The utility model discloses the aperture when only having produced the pjncture needle and having worn on the well disc, because the isolation plug body material is medical elastic material, can seal the pinhole that the pjncture needle left immediately when the pjncture needle is extracted, the difficult condition that produces the weeping, puncture channel's use has both saved the material and has reduced the frictional force when the pjncture needle inserts.
Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a novel isolation stopper that uses in needle is kept somewhere to vein.
Background
The disposable indwelling needle consists of a protective sleeve, a catheter component, a needle tube component, a hose component, a heparin cap, a water stop clamp, a connector and the like, wherein the catheter component consists of a catheter, a metal wedge, a sealing isolation plug and a catheter seat. When in use, the hose seat of the venous indwelling needle is well connected with an infusion apparatus or an injector to exhaust bubbles; selecting a part suitable for puncture, puncturing a vein after disinfection according to a conventional method, sending the catheter into the vein while pulling out the puncture needle tube after blood return is seen, finally completely pulling out the puncture needle tube, and keeping the catheter in the vein and fixing the catheter, thereby carrying out multiple times of transfusion on a patient.
Patent No. CN107308520A discloses an isolating plug, in which the upper and lower ends of the isolating plug are provided with incisions communicated with the puncture channel, and once the incisions deform due to temperature change or extrusion, the infused liquid or the blood of the patient can flow out from the incisions, thereby increasing the probability of cross infection between the patient and the medical staff and causing injury to the patient and the medical staff.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel isolating plug used in a vein indwelling needle.
The utility model discloses an innovation point lies in, the utility model provides an isolation stopper does benefit to the pjncture needle and inserts, but can not produce the condition of weeping again.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: a novel isolating plug used in a venous indwelling needle comprises an isolating plug body, wherein the isolating plug body is of a cylindrical structure and comprises a disc, a first semicircular plunger body and a second semicircular plunger body, the disc is positioned above the first semicircular plunger body and the second semicircular plunger body, the first semicircular plunger body and the second semicircular plunger body are the same in size and shape, the bottom surface of the disc is connected with the top surface of the first semicircular plunger body, and the bottom of the first semicircular plunger body is connected with the bottom of the second semicircular plunger body; a puncture channel parallel to the axial direction of the isolating plug body is formed between the first semicircular plunger body and the second semicircular plunger body; the isolation plug body is made of medical elastic material.
The puncture channel saves materials and reduces the friction force when the puncture needle is inserted, only small holes are formed in the disc when the puncture needle penetrates through the disc, and the isolation plug body is made of medical elastic materials, so that a needle hole left by the puncture needle can be immediately sealed when the puncture needle is pulled out, and liquid leakage is not easy to occur.
Furthermore, the disc, the first semi-circular plunger body and the second semi-circular plunger body are integrally formed. Is beneficial to production and assembly.
Further, the middle part of the periphery of the isolating plug body is provided with an annular groove. The isolating plug is arranged in a catheter seat of the indwelling needle during use, and glue can be injected into the annular groove of the isolating plug through two symmetrical small holes arranged on the catheter seat, so that the isolating plug is fixed in the catheter seat.
Further, the puncture channel is of a gourd-shaped structure. The leakage can be further prevented, when the leakage appears at the bottom of the isolating plug body, the leakage enters the cavity at the lower part of the puncture channel, and the isolating plug is protected by the gourd-shaped structure.
Further, the medical elastic material is isoprene rubber or medical silica gel.
The utility model has the advantages that:
1. The utility model discloses the aperture when only having produced the pjncture needle and having worn on the well disc, because the isolation plug body material is medical elastic material, can seal the pinhole that the pjncture needle left immediately when the pjncture needle is extracted, the difficult condition that produces the weeping, puncture channel's use has both saved the material and has reduced the frictional force when the pjncture needle inserts.
2. The utility model provides a puncture channel of calabash column structure makes the isolation stopper realize the duplicate protection.
