Description

anti-needle indwelling needle

technical field

The product of the utility model relates to a medical appliance, in particular to a venous indwelling needle used for intravenous infusion, blood transfusion, etc. of a human body. the

Background technique

The indwelling needle is generally used for clinical infusion of medicinal liquid to patients, because it has the advantages of reducing the number of blood vessel punctures, reducing exudate, and enabling rapid infusion of medicinal liquid, which is beneficial to alleviate the pain of patients and facilitate rescue. the

But the disadvantage of the existing indwelling needle is that after venipuncture, the needle tube is pulled out, and the sharp needle tube after use will be exposed, so when cleaning and destroying the indwelling needle tube, it is easy to stab medical staff or other people, causing cross infection. At present, the anti-acupuncture indwelling needle is based on the addition of an anti-acupuncture device on the basis of the ordinary indwelling needle in the past. After the indwelling needle is used up, the anti-acupuncture device can effectively protect the sharp needle tube from exposure, so fundamentally To prevent medical staff from being punctured by the puncture needle and the occurrence of infection. the

Contents of the invention

The purpose of this utility model is to provide an anti-acupuncture indwelling needle, which has good safety performance and is easy to operate. After venipuncture, the needle is withdrawn along the guide groove, and the needle tube slides in the guide sleeve with the needle seat. When reaching the rear end of the guide sleeve, the clamping position of the clamping rod part is snapped into the snap ring, so that the position limit plays the role of restricting the movement, the needle tube is stably fixed, and at this time the needle tube is also completely protected in the guide sleeve, so as to avoid the Expose and puncture medical personnel or others. the

The purpose of this utility model is achieved in this way, an anti-acupuncture indwelling needle, which includes: a sheath, a needle tube, a catheter, a needle core, a seal, a needle seat, a catheter seat, a pipe clamp, a flexible pipe, an antibacterial cap, Infusion connector, positive pressure connector and anti-needle stick device. It is characterized in that a detachable anti-acupuncture device is installed at the rear end of the catheter seat, and the anti-acupuncture device is divided into three parts, namely, a clamping rod part, a snap ring part and a guide sleeve part. One end of the clamping rod part is fixed in the back hole of the needle seat, and the other end is provided with a clamping position, which is convenient to be clamped into the clamping ring to play a limiting role; one end of the clamping ring part is connected to the end of the guide sleeve through the clamping hole, and the other end is The claw style is convenient to fix and limit the clamping position on the rod; the guide sleeve part is provided with a guide groove, which is convenient for indwelling needles. At the rear end, the clamping position of the clamping rod is clamped into the clamping ring, so that the position limit plays a role in restricting the movement. At this time, the needle tube is also completely protected in the guide sleeve, so as to avoid hurting medical staff or others due to the exposure of the needle tube. the

With the above technical solution, after the indwelling needle is used, the exposed needle tube can be snapped into the snap ring through the clamping position on the lever, so as to play a stable locking and limiting role, so that the needle tube is completely protected in the guide sleeve , to achieve safety, avoid stabbing medical staff or others, and reduce cross-infection and contamination. the

Below in conjunction with accompanying drawing and embodiment example, product of the utility model is further described. the

Detailed ways

As shown in Figure 1, an anti-acupuncture indwelling needle, including: 1 sheath, 2 catheters, 3 needle cores, 4 seals, 5 needle seats (single wing), 6 clamping rods, 7 guide sleeves, 8 snap rings , 9 needle tubes, 10 catheter bases, 11 hoses, 12 tube clips, 13 anti-bacterial caps, 14 infusion connectors and 15 positive pressure connectors. the

An anti-acupuncture indwelling needle, which includes: a sheath 1, a needle tube 9, a catheter 2, a needle core 3, a seal 4, a needle seat 5 that is a single wing, a catheter seat 10, a tube clamp 12, a hose 11, an anti-needle Bacteria cap 13, infusion connector 14, positive pressure connector 15 and anti-acupuncture device. It is characterized in that a detachable anti-acupuncture device is installed at the rear end of the catheter base 10, and the anti-acupuncture device is divided into three parts, which are respectively 6 parts of the clamp rod, 7 parts of the guide sleeve and 8 parts of the snap ring. One end of the lever part is fixed in the back hole of the needle seat, and the other end is provided with a card position, which is convenient to be inserted into the clamp ring to play a limiting role; the guide sleeve part is provided with a guide groove, which is convenient for the indwelling needle to use during the needle withdrawal process , the needle tube slides with the needle seat in the guide sleeve.
