Disposable syringes are made of polymer polypropylene materials, divided into three-part and two-part types. The three-part type structure is composed of three pieces of core rod, rubber stopper, outer cover, injection needle, and outer packaging. The two-part type structure is composed of a core rod, a jacket, an injection needle, and an outer package. Some syringes have a screw port design and use double threads to fix the needle.
The Auto disable syringe is a disposable syringe product that can prevent repeated use after use. After the injection is completed, manual or mechanical force is required to prevent the push rod from being drawn out of the barrel to achieve self-locking, or the sealing performance of the piston is destroyed, or the plunger of the syringe can be inferred, ultimately achieving the purpose of preventing reuse.
The safe clip syringe consists of a syringe, a needle, and a needle protective cover. When in use, the needle protective sleeve is cut along the parallel direction of the needle, the protective sleeve is pulled away from the needle for injection, and the protective sleeve is reset after the injection, so that the needle no longer hurts people, so as to achieve the purpose of preventing repeated use at one time. After use, its sharp parts are effectively protected, so that accidental injury to medical staff and others can be avoided.
It is a syringe specially used to inject insulin. It consists of a needle cap, an injection needle, a syringe, and a pusher. Usually, this type of syringe is directly marked with a unit (U) on the barrel. Therefore, the doctor asks you to inject several units of insulin, as long as you inject the several units marked on the barrel.
The infusion set is a common medical consumables used for intravenous infusion. Generally, it is composed of eight parts connected by intravenous needle or injection needle, needle cap, infusion tube, medical liquid filter, flow rate regulator, drip pot, cork puncture device, and air filter.
This is based on the ordinary infusion set, plus a medicine port design(Y site).

A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. A tube made of natural rubber, silicone rubber, or polyvinyl chloride (PVC) can be inserted into the bladder through the urethra to drain urine out. After the catheter is inserted into the bladder, there is a balloon near the tip of the catheter to fix the catheter. The tube stays in the bladder and is not easy to come out, and another side drainage tube is connected to the urine bag to collect urine.
The main types of urinary catheters are:
One way urinary catheter. Usually, there is no balloon, only one channel, difficult to fix, and short indwelling time.
Two-way urinary catheter. There are two lumens, one is the water injection hole and the other is the liquid outlet. Can be fixed, mainly used for indwelling catheterization.
Three-way urinary catheter. There are three cavities, one for water injection cavity, one for medicine another for injection cavity, and drainage cavity. Mainly used for short-term indwelling urinary catheterization, intravesical drug drip, irrigation, drainage, etc.
Nasal oxygen tube is to place the opening of the nasal oxygen tube in the nostril. The air outlet of the nasal oxygen tube is smaller than the nostril. There is a gap around the exit, which can breathe air while inhaling oxygen. This gap is also used to exhale, more comfortably. The nasal oxygen tube is equipped with an oxygen supply system for the human body to inhale oxygen. The nasal oxygen tube is composed of nasal congestion, front catheter, rear catheter, three-way connector, and horn connector. According to the shape of nasal congestion, it can be divided into two types: single nose and double nose. According to the size of nasal congestion have three specifications: large, medium, and small. The use of the nasal oxygen tube is to connect the horn connector to the oxygen supply system equipped with a humidification bottle interface, put the nasal plug end on the patient’s head and insert the nasal plug into the patient’s nostrils, and then adjust the amount of oxygen output from the oxygen humidification bottle to inhaled oxygen.
The disposable suction catheter is made of medical polymer materials, composed of a catheter and a joint, and is a sterile product used for clinically extracting sputum or secretions in the trachea. A disposable suction catheter is divided into 6 models according to different tube diameters, they are F4, F6, F8, F10, F12, F16.
The function of a disposable stomach tube is mainly used to extract gastric juice, or prepare the enteral nutrient solution, and inject it into the stomach to provide patients with daily food and nutrition.
Disposable anal tube, made of medical polymer materials, used for anal exhaust, enema, etc.
Disposable mucus extractor is generally composed of a night storage bottle, a suction tube, a negative pressure tube, a joint, a bottle cap, etc., for clinical sputum suction.
The role of chest drainage bottle:
1. Airtight, through the surface of the drainage bottle to prevent air from entering the chest cavity and causing pneumothorax or pneumothorax aggravation;
2. Drainage can drain the pleural effusion or gas in the chest cavity out of the body;
3. Prevent the mediastinum from swinging, making the bilateral thoracic pressure equal through the fluctuation of the water column of the drainage bottle, avoid causing the mediastinum to swing and affect the breathing and circulation function;
4. Maintain negative pressure in the pleural cavity;
5. It is easy to observe. Through the fluctuation of the water column, the patency of the drainage tube can be observed, such as the drainage of pleural effusion, the color and volume of the pleural effusion can be observed, if the pneumothorax is drained, the drainage bottle can be used to observe whether there is air bubble overflow and understand the lungs air leak.
The closed wound drainage system is to produce the negative pressure state of its suction head through a certain method, suck out the liquid in the wound with the help of negative pressure, effectively prevent the waste liquid from accumulating and at the same time form internal fixation to the body cavity, and accelerate the wound healing time. The closed wound drainage system is suitable for clinical departments, mainly used for medical drainage, sputum discharge, blood discharge, and secretion, etc.
An oxygen mask is a device that transfers oxygen from a storage tank to the lungs of the human body for auxiliary treatment. Common oxygen masks are mainly composed of nose clips, masks, elastic bands, mask connectors, oxygen tubes, and conical connectors.
The non-rebreather mask is composed of an oxygen bag, oxygen bag connector, conversion connector, side hole, mask, nose clip, elastic band, conical connector, oxygen tube, conical connector, mask connector, etc. This kind of mask does not take in inhalation and exhalation. One channel so that the exhaled air will not be inhaled repeatedly. Traditional oxygen masks always have part of the exhaled air which is re-inhaled, because the exhaled air contains relatively high carbon dioxide. After this part of the gas is repeatedly inhaled, it will dilute the inhaled oxygen.
It is suitable for spraying the treatment of respiratory diseases. It is mainly composed of nose clips, face mask, conversion joint, elastic band, atomization tank, cone joint, oxygen tube, cone joint, etc.
The Venturi mask is made according to the Venturi principle, when oxygen enters the mask through a narrow channel, negative pressure is generated around the jet flow, and a certain amount of air flows into the mask from the open edge, and the size of the side seam of the mask changes the air and the ratio to oxygen. Because the airflow injected into the mask is greater than the maximum flow rate and tidal volume of the patient during inhalation, the oxygen concentration is constant. As the high flow rate of the gas continuously flushes the inside of the mask, it is difficult for the exhaled breath to stay in the mask, so there is basically no repeated breathing. Treatment of patients with hypoxemia and hypercapnia.
Manual resuscitator consists of a mask, a one-way valve, a ball, and an oxygen storage valve. It is generally used in emergency cardiopulmonary resuscitation, respiratory muscle paralysis caused by nerve and muscle diseases, and various large-scale operations.
The anesthesia mask consists of a fixed ring (only for adults), a mask body (including interfaces), an air bag, and a one-way valve. The function is to connect with the anesthesia breathing circuit through the connector on the anesthesia mask, the anesthesia breathing circuit is connected with the anesthesia breathing machine or the oxygen supply equipment, covering the cushion of the gas to the patient’s mouth and nose, and the connection forms a pathway for fresh oxygen gas, delivery to the patient’s respiratory tract.
The laryngeal mask is composed of a ventilation tube and a ventilation mask. The ventilation catheter is similar to the ordinary trachea. It is made of silicone. It has an opening at one end that can be connected to an anesthesia machine or ventilator. The other end is a ventilating mask. The ventilating mask forms an airway in the throat. The ventilating mask is oval and made of soft rubber, the periphery is raised, and the inside is a cavity. At the junction of the ventilation catheter and the ventilation mask, the slope of the catheter cavity is 30°, and the black line behind the ventilation catheter helps to identify the distortion of the catheter. At the upper part of the entrance of the ventilation tube into the ventilation mask, there are two vertical fences to form several longitudinal slits to prevent the epiglottis from blocking the lumen. The proximal end of the ventilation mask is connected with the gas injection pipe, and the gas can be expanded by injecting gas inward through the gas injection pipe. Used in general anesthesia to establish a safe airway.
These are all common disposable medical caps, which are medical supplies used in clinical health care in medical systems, and are used for general isolation in outpatient clinics, wards, and laboratories of medical institutions.
Disposable gloves are a common medical consumable, it has the following conventional classifications:
1. Surgery or Examination.
According to the different environments in which medical gloves are used, general disposable medical gloves can be divided into two categories: surgical gloves and examination gloves. Surgical gloves refer to the gloves worn by medical staff during surgery, while examination gloves are the gloves used by medical staff for diagnosis, treatment, and surface inspection of patients. Relatively speaking, the sanitary requirements of surgical gloves will be more stringent than examination gloves, requiring sterilization and independent packaging.
2. With or Without Powder
According to whether the gloves contain powder, medical gloves can be divided into powdered medical gloves and powder-free medical gloves. The powder in the gloves is to increase the handgrip of the medical staff so that they can still hold the medical tools firmly in the slippery operating environment, without slipping and other errors.
However, some people are allergic to powdered, and the powder sometimes affects the diagnosis and treatment results. From the perspective of professionalism and safety, it is more appropriate for medical staff to choose powder-free gloves.
3. Sterile or Non-sterile
Disposable gloves worn by medical staff during surgery have higher requirements and must be safe, hygienic, and healthy. Otherwise, direct contact with the patient’s body is prone to adverse effects. Therefore, sterilized medical surgical gloves must be used. In other cases, medical gloves can be non-sterile.
4. Nitrile or Latex
According to the material of medical gloves, there are nitrile gloves and latex gloves. Latex gloves were first used in the medical field, but because some people are allergic to latex proteins in a latex glove, medical nitrile gloves are now used in some medical fields.
Medical protective clothing refers to the protective clothing used by medical staff (doctors, nurses, public health personnel, cleaning staff, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, people entering infected areas, etc.). Its function is to isolate germs, harmful ultrafine dust, acid and alkaline solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.
According to the purpose and use occasions can be divided into daily work clothes, surgical clothes, isolation gowns, and protective clothing:
Daily work clothes are the coats worn by medical staff in their daily work, also known as white coats;
Surgical gown refers to specially designed clothing worn in the operating room;
Isolation clothing is the clothing worn by medical staff when they come in contact with patients, or when family members visit patients;
Protective clothing is the clothing worn by people who enter special areas such as medical emergency, infectious disease area, electromagnetic radiation area, etc.
Medical masks are generally made of one or more layers of non-woven fabrics. They are medical protective products that can resist liquids, filter particles, and bacteria. Medical masks are generally divided into three categories, they are disposable medical masks, medical-surgical masks, and medical protective masks:
1. Disposable medical masks
Disposable medical masks are generally used in ordinary medical environments and do not have too many requirements for adhesion and blood isolation. Common disposable medical masks are divided into two types: ear strap type and lace type. In appearance, they are similar to medical surgical masks.
2. Medical-surgical masks
Medical-surgical masks are generally used in environments with body fluids and blood splashes, such as hospital operating rooms. This type of mask can effectively isolate blood and body fluids and prevent blood and body fluids from passing through the mask to infect the wearer.
3. Medical protective masks
Medical protective masks are generally used in environments with respiratory infectious diseases. They can filter particles in the air and block pollutants such as droplets, blood, body fluids, and secretions. The filtration efficiency of non-oily particles can reach more than 95%. An adhesive self-priming filter type medical protective equipment.
Medical absorbent cotton is the main sanitary material used in the medical industry for wound dressing, protection, cleaning and other purposes. It is also a medical device product that directly contacts the wound. Compared with ordinary cotton, it removes the non-absorbent lipids on the surface of cotton, and enhances the absorption of liquid medicine and body fluids by cotton.
Disposable medical cotton swabs are made of medical absorbent cotton and natural birch wood. They are mainly used to disinfect patients’ skin, treat wounds, and apply medicine.
Gauze is a cotton fabric with sparse warp and weft. It belongs to the raw material of textiles and is a kind of cloth. Generally speaking, medical gauze is also called degreased gauze, which can be used clinically for the drainage of incisions, plugging leaks, and covering wounds after surgery, which are beneficial to the repair of body tissues. Therefore, it is widely used in clinical practice.
Bandages are gauze bands used to wrap wounds or affected areas and are common medical supplies. The simplest one is the single-shed belt, which is made of gauze or cotton and is suitable for the limbs, head, chest, and abdomen. Double bandages are bandages of various shapes made according to parts and shapes. The material is a double-layer cotton cloth, which can be sandwiched between different thicknesses of cotton. There are cloth strips around it for knotting and fixing. Chest bandage, abdominal bandage, etc. Special bandages are mostly used for fixing the limbs and joints.
Medical tape is a common medical consumable, often used to bandage wounds. According to the material, it can be divided into four categories:
Non-woven tape: very low irritation, no tingling sensation when torn off, it feels lighter and breathable. But the disadvantage is that the strength is relatively low and it is not waterproof.
PE tape: at the expense of certain permeability in exchange for higher strength, there is a certain degree of waterproofness, but the irritation of tearing off is relatively obvious.
Zinc oxide tape: zinc oxide is not the material of the tape itself, the tape material itself is pure cotton, and zinc oxide is the coating impregnated on the tape. This kind of tape has the highest strength and the strongest water resistance, and the irritation to tear off is similar to that of PE tape.
Silk tape: strong adhesion, low sensitization, no residual glue, no damage to the skin, strong air permeability, and easy to tear off.
