Description

Disposable self-venting anti-needle stick blood transfusion set

technical field

The utility model belongs to disposable medical equipment, in particular to a disposable self-exhausting anti-acupuncture blood transfusion device. the

Background technique

Disposable blood transfusion sets used clinically in clinical units of various domestic medical institutions are mainly composed of cork piercer protective cover, cork piercer, air filter, infusion hose, dropper, drip funnel, blood filter, flow regulator Composed of intravenous infusion needles, the traditional use method is: some need to get rid of the air in the infusion tube before performing venipuncture on the patient. There are usually two manual methods: one is to insert the cork piercer into the upside-down blood transfusion bag stopper, and let the dropper discharge the air in the dripping funnel above the lower liquid outlet, and let the dripping funnel fill with half of the dripping funnel. A large number of air bubbles can be avoided by being vertical; another method is to close the flow regulator, squeeze the drip funnel to suck the blood to about 1/2 to 2/3 of the drip funnel, and then slowly open the flow regulator, which can also avoid Produces numerous bubbles. But these two kinds of methods all will expend a lot of time of medical personnel, as slightly improper during operation, medical personnel then will discharge a certain amount of liquid medicine to get rid of air bubble, cause inconvenience to medical personnel like this; In addition, because some patients may Such as AIDS, hepatitis B, and hepatitis C virus carriers, the used needles are very easy to accidentally injure medical staff or other personnel and cause infection, endangering the health of others. the

Utility model content

The purpose of the utility model is to provide a one-time use self-venting anti-acupuncture blood transfusion set, which solves the technical problems that the existing infusion sets cannot be automatically vented and the accidental injury caused by needles after use can be avoided. the

In order to achieve the above object, the utility model adopts the following technical solutions:

A disposable self-exhausting anti-needle-puncture blood transfusion set, including a protective cover for a bottle stopper piercer, a bottle stopper piercer, an upper hose, a dripping funnel cover, a latex cap, a self-exhausting device, a dripping funnel, a blood filter, Lower coupler, lower hose, flow regulator, union with taper head, intravenous infusion needle and anti-acupuncture sheath, intravenous infusion needle consists of needle sheath, puncture needle tube, needle handle, thin hose, needle seat, The protective sleeve of the cork piercer is set on the cork piercer, the cork piercer, the upper hose, the dripping funnel cover, the dripping funnel, the lower coupler, the lower hose, and the coupler with a cone head are connected in sequence, and the latex cap is sleeved on the On the dosing port of the dripping funnel cover, the blood filter is clamped in the dripping funnel, the flow regulator is set on the lower hose, the needle seat of the intravenous infusion needle is sleeved on the union with a tapered head, the puncture needle tube, needle handle, thin The hose and needle seat are sequentially connected by adhesive, and the needle sheath is sleeved on the needle handle. It is characterized in that: the self-exhausting device is composed of an air plug, an air filter membrane and an exhaust channel on the dripping funnel cover. The cover is buckled on the thin tube of the intravenous infusion needle, and the anti-acupuncture sheath can slide back and forth on the thin tube of the intravenous infusion needle, and the needle handle and needle tube of the intravenous infusion needle can be clipped on the anti-acupuncture sheath Inside. the

The above-mentioned disposable self-venting anti-acupuncture blood transfusion set can also be equipped with an air intake device, which is composed of an air filter, an air intake hose, an air intake steel needle and a needle sheath. the

In the above-mentioned self-venting device of the disposable self-venting anti-acupuncture blood transfusion set, the air plug tightly presses the air filter membrane into the outlet port of the exhaust channel, or uses high-frequency heat sealing to heat seal the air filter film to the outlet port of the exhaust channel inside the port and secure with an air plug. the

The anti-acupuncture sheath of the above-mentioned disposable self-venting anti-acupuncture blood transfusion set is formed by folding and pressing from both sides. After the engagement, the rear part is a closed ring, and the front side wall of the buckle is Along the axial direction, a meandering slot is formed. the

Before the anti-acupuncture sheath of the above-mentioned disposable self-venting anti-acupuncture blood transfusion set is engaged, the upper and lower covers can be connected by side connection points on one side, and the rear parts of the other two sides are provided with buckles and connected with it. Matching card holes. the

The upper or lower wall of the axially tortuous slot of the anti-needle-stick sheath of the disposable self-venting anti-needle-stick blood transfusion set is provided with non-return steps, convex points and corresponding depressions. the

There may be 2 or 3 or more edge connection points of the needle-stick-proof sheath of the above-mentioned disposable self-venting needle-stick-proof blood transfusion set. the

The front part of the anti-needlestick sheath of the disposable self-venting anti-needlestick blood transfusion set has an open oblique ellipse shape, the unopened part is at the end of the edge connection point, and the open part is the starting point of the slot. the

By adopting the above-mentioned technical scheme, the utility model has the following advantages: Compared with the disposable blood transfusion set routinely used clinically, the utility model is connected with a self-exhaust device at the lower part of the drip funnel, and the self-exhaust device is composed of an air plug, an air filter Before inserting the bottle stopper piercer into the blood bag stopper, open the inner plug of the air plug on the self-venting device, and close the flow regulator, insert the bottle stopper piercer and/or the air inlet device into the bottle After the needle is inserted into the blood bag, the blood in the blood bag will quickly and automatically flow into the drip funnel due to the air inlet and the self-exhaust device on the cork piercer being connected to the atmosphere and the hydraulic pressure difference in the blood bag. As the surface rises, the blood takes the air in the dripping funnel into the air from the exhaust port on the top of the exhaust channel, and discharges it through the exhaust channel, the air filter membrane of the exhaust port and the air plug. After the air inlet, it enters the exhaust passage to the air filter membrane. Because the air filter membrane has the function of preventing water from flowing out and can withstand a certain pressure, the liquid level will no longer rise and stay on the top of the air inlet of the exhaust passage, that is, greater than 1/2 of the length of the drip funnel; it only takes 3-5 seconds for the blood to flow into the drip funnel. After opening the flow regulator, the blood temporarily stored in the drip funnel can quickly pass through the blood filter and enter the lower hose. There is no need to exhaust the blood transfusion set, which shortens the original exhaust time, facilitates the operation of the medical staff, saves waiting time, and increases work efficiency; in addition, because of the anti-acupuncture sheath, the utility model can pull out the needle after the blood transfusion Finally, you need to pinch the buckle position of the anti-needle sheath with one hand, and pull back the thin hose at the back of the anti-needle sheath with the other hand to pull the needle handle back into the anti-needle sheath, so as to avoid accidental needle sticking. Injuries occur. the
