Abstract

The utility model provides an upper arm transfusion harbor needle puncture fixed auxiliary device, includes a positioning seat and two viscidity dressing, and the positioning seat is the frustum of a cone form, runs through along the axial in the positioning seat and is provided with a taper hole, and the bottom of positioning seat outwards is provided with a first annular limit, runs through in the offside lateral wall of positioning seat and is provided with the connection breach, all is provided with a tearable connecting block in the offside opening respectively, two viscidity dressing's side all be provided with a semicircle groove respectively, first annular limit is pasted on viscidity dressing. Because the positioning seat is fully attached to the infusion port injection seat for positioning, the top hole of the taper hole is smaller, so that the puncture opening of the infusion port injection seat can be accurately positioned, the accurate puncture can be performed on the infusion port injection seat only by extending the port needle into the positioning seat, the needle insertion deviation is prevented, the needle insertion accuracy and success rate are improved, the needle point is not easy to deviate after the puncture, the drug is prevented from being oozed, and the damage of the infusion port silica gel film is reduced.

Description

Upper arm transfusion harbor needle puncture fixing auxiliary device

Technical Field

The utility model relates to a human living article, in particular to a medical instrument, and especially relates to an upper arm transfusion harbor needle puncture fixing auxiliary device.

Background

The transfusion port is an intravenous transfusion device which is planted subcutaneously and is kept in the body for a long time, and is clinically suitable for patients needing long-term transfusion and chemotherapy. The upper arm transfusion port has the advantages of effectively preventing the clamping syndrome of the pneumothorax, the catheter and the pneumothorax caused by puncture and tube placement, being simple and convenient to operate, small in port seat, small in incision, attractive, protecting the privacy of patients and not affecting chest radiotherapy and radiography. However, in the prior art, due to the small port body, the nursing staff cannot accurately position and fix the puncture, and the puncture easily deviates and slides out, so that the drug is extravasated. Repeated punctures tend to increase the risk of infection, resulting in damage to the silicone membrane of the port.

Disclosure of Invention

The utility model aims to provide an upper arm transfusion harbor needle puncture fixing auxiliary device, which aims to solve the technical problem that the transfusion harbor fixing seat cannot be accurately positioned and fixed for needle insertion in the prior art.

The utility model relates to an upper arm transfusion port needle puncture fixing auxiliary device which comprises a positioning seat and two adhesive dressings, wherein the positioning seat is in a truncated cone shape, a taper hole is formed in the positioning seat in an axial penetrating manner, a first annular edge is outwards arranged at the bottom of the positioning seat, a connecting split is formed in the opposite side wall of the positioning seat in a penetrating manner, a tearable connecting block is respectively arranged in the opposite side opening, a semicircular groove is respectively arranged on the side edges of the two adhesive dressings, the two semicircular grooves are oppositely arranged, the first annular edge is adhered to the adhesive dressing, and the taper hole corresponds to the two semicircular grooves.

Further, the number of the openings is two, and the two openings are symmetrically arranged.

Further, a second annular edge is arranged at the top of the positioning seat inwards.

Furthermore, the positioning seat is formed by tearable silica gel or tearable plastic.

Compared with the prior art, the utility model has positive and obvious effects. Because positioning seat and infusion port injection seat fully laminate the location, the top aperture of taper hole is less, consequently can accurately fix a position the puncture mouth of infusion port injection seat, just need stretch into the positioning seat with the port needle in just can carry out accurate puncture to infusion port injection seat, prevent to prick the skew, improve accuracy and the success rate of pricking, make the needle point be difficult to deviate from after the puncture, prevent the medicine extravasation, reduce the damage of infusion port silica gel membrane, extension infusion port life, reduce the infection risk because of the repeated puncture leads to, reduce the relevant complication of puncture pricking (such as pain, hematoma and subcutaneous tissue infection), improve nursing staff and patient satisfaction.

Detailed Description

The present utility model is further described below with reference to the drawings and examples, but the present utility model is not limited to the examples, and all the similar structures and similar variations using the present utility model should be included in the protection scope of the present utility model. The use of the directions of up, down, front, back, left, right, etc. in the present utility model is only for convenience of description, and is not a limitation of the technical scheme of the present utility model.

As shown in fig. 1-4, the upper arm transfusion harbor needle puncture fixing auxiliary device comprises a positioning seat 1 and two adhesive dressings 2, wherein the positioning seat 1 is in a truncated cone shape, a taper hole 3 is formed in the positioning seat 1 in an axial penetrating manner, a first annular edge 4 is arranged at the bottom of the positioning seat 1 outwards, connecting slits 5 are formed in the side walls of two sides of the positioning seat 1 in a penetrating manner, a tearable connecting block 6 is respectively arranged in the connecting slits 5, semicircular grooves 7 are respectively formed in the side edges of the two adhesive dressings 2, the two semicircular grooves 7 are oppositely arranged, the first annular edge 4 is stuck on the adhesive dressing 2, and the taper hole 3 corresponds to the two semicircular grooves 7.

Further, the number of the slits 5 is two, and the two slits 5 are symmetrically arranged.

Further, a second annular edge 8 is provided inwardly on the top of the positioning seat.

Further, the positioning seat 1 is made of tearable silica gel or tearable plastic.

Specifically, the adhesive dressing, the truncated cone shape, the taper hole 3, the tearable connecting block 6, the tearable silica gel, the tearable plastic, etc. in this embodiment all adopt the known schemes in the prior art, and those skilled in the art will understand that the description is omitted here.

The working principle of the embodiment is as follows: the port injection site has been left under the patient's skin. When the disposable infusion port injection seat is used, two adhesive dressings 2 are firstly adhered to the skin around the infusion port injection seat respectively, then the first annular edge 4 of the positioning seat 1 is adhered to the adhesive dressing 2, the positioning seat 1 surrounds the infusion port injection seat, the adhesive dressing 2 plays a role of fixing the positioning seat 1, a nursing staff does not need to hold the positioning seat 1 all the time, the positioning seat 1 and the infusion port injection seat are fully adhered and positioned, the top aperture of the taper hole 3 is smaller, so that the puncture opening of the infusion port injection seat can be accurately positioned, the accurate puncture can be carried out on the infusion port injection seat only by extending the port needle into the positioning seat 1, the puncture offset is prevented, the puncture accuracy and success rate are improved, the needle point is not easy to deviate after puncture, the drug extravasation is prevented, the damage of the port silicon rubber film is reduced, the service life of infusion nursing is prolonged, the infection risk caused by repeated puncture is reduced, the related complications (such as pain, hematoma and subcutaneous tissue infection) of the puncture nursing staff and the patient are improved. After the port needle is punctured, the port needle is fixed in the transfusion port, the positioning seat 1 is torn along the split 5, the tearable connecting block 6 is disconnected with the positioning seat 1, the split 5 of the positioning seat 1 is opened, and then the positioning seat 1 and the adhesive dressing 2 can be removed. The device has low cost of materials, is convenient to popularize and is convenient for clinical application.
