Description

A new type of sealing isolation plug

technical field

The invention relates to the field of medical equipment, in particular to a novel sealing isolation plug.

Background technique

Disposable indwelling needles are composed of protective sheath, catheter assembly, needle tube assembly, hose assembly, heparin cap, water stop clip and connector, among which the catheter assembly is composed of a catheter, a metal wedge, a sealing isolation plug and a catheter seat. When in use, connect the hose seat of the venous indwelling needle to the infusion set or syringe to remove air bubbles; select a site suitable for puncture, sterilize the vein according to conventional methods, puncture the vein, and pull out the puncture needle after seeing the blood return. The catheter is sent into the vein, and finally the puncture needle is completely pulled out, the catheter is indwelled in the vein and fixed, and the patient can be given multiple infusions. The sealing isolation plug plays the role of sealing isolation, which can isolate the external bacteria and viruses and prevent them from entering the inside of the catheter. Therefore, whether the sealing performance of the sealing isolation plug is still good after multiple puncture needles is a very important performance. In the existing production process of venous indwelling needle isolation plug, often due to the incision at the production site of the isolation plug, the phenomenon of chipping is serious, which seriously affects the assembly quality; and when the finished indwelling needle is assembled, the puncture needle is used to puncture the "isolation plug" because of its center There is no channel or one-way channel, which leads to high puncture friction, easy to drop chips and increase the difficulty of puncture needle assembly; at the same time, the isolation plug cannot completely seal the hole or gap left after the puncture needle is pulled out, resulting in the infusion of liquid or patient. The blood flows out of the isolation plug holes or gaps, which increases the risk of cross-infection between patients and medical staff, and causes harm to patients and medical staff.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the deficiencies in the prior art and provide a new type of sealing isolation plug, which reserves a bidirectional channel, is convenient for puncturing with a puncture needle, and can maintain good sealing performance after multiple punctures.

In order to solve the problems of the prior art, the present invention discloses a novel sealing isolation plug, comprising an isolation plug body, and a connection groove in the middle of the isolation plug body, and the connection groove is recessed toward the centerline of the isolation plug body; The top is provided with a transverse incision, the transverse incision extends downward from the top of the isolation plug body to the position corresponding to the connection groove on the isolation plug body, and a longitudinal incision is provided at the bottom of the isolation plug body, and the longitudinal incision extends from the bottom of the isolation plug body It extends upward to the position corresponding to the connection groove on the isolation plug body; the transverse incision and the longitudinal incision are connected at the corresponding position of the connection groove on the isolation plug body.

Preferably, the width of the transverse slit and the longitudinal slit is smaller than the smallest diameter of the isolation plug body.

Preferably, the widths of the transverse incision and the longitudinal incision are the same.

Preferably, the directions of the transverse incision and the longitudinal incision are perpendicular to each other.

Preferably, the inwardly recessed depth of the connecting groove is smaller than the radius of the location where the connecting groove is located.

The beneficial effects of the present invention are as follows: puncturing is convenient, a transverse incision and a longitudinal incision are respectively provided at the top and bottom of the isolation plug body, the transverse incision and the longitudinal incision are connected and the directions are perpendicular to each other, and the puncture is inserted inward along the middle of the transverse incision , you can enter the longitudinal incision along the way, and the puncture is more convenient. Compared with non-channel and one-way channel isolation plugs, it is more labor-saving and does not generate debris that can affect injection. The sealing effect is good. Two perpendicular incisions are used on the top and bottom of the isolation plug body, which has a better isolation effect. Compared with the one-way channel that penetrates directly, it can prevent bacteria and viruses from entering. And after the puncture is completed, the incision can quickly rebound, avoiding the difficult recovery of the puncture caused by direct puncture. The connection is tight, and an inwardly recessed connection groove is provided to facilitate the introduction of the isolation plug body into the catheter, and sealant can be injected to achieve effective sealing after introduction.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only intended to more clearly illustrate the structure of the present invention.

A novel sealing isolation plug, comprising an isolation plug body 1, a connecting groove 2 in the middle of the isolation plug body 1, and the connecting groove 2 is recessed towards the centerline of the isolation plug body 1; a transverse cut is provided on the top of the isolation plug body 1 3. The transverse incision 3 extends downward from the top of the isolation plug body 1 to the position corresponding to the connection groove 2 on the isolation plug body 1, and a longitudinal incision 4 is provided at the bottom of the isolation plug body 1, and the longitudinal incision 4 is self-isolating The bottom of the plug body 1 extends upward to the position corresponding to the connection groove 2 on the isolation plug body 1 ;

The widths of the transverse incision 3 and the longitudinal incision 4 are smaller than the minimum diameter of the isolation plug body 1, the widths of the transverse incision 3 and the longitudinal incision 4 are the same, and the directions of the transverse incision 3 and the longitudinal incision 4 are perpendicular to each other.

The inwardly recessed depth of the connecting groove 2 is smaller than the radius of the position where the connecting groove 2 is located.

The beneficial effects of the present invention are: puncturing is convenient, the top and bottom of the isolation plug body 1 are respectively provided with a transverse incision 3 and a longitudinal incision 4, the transverse incision 3 and the longitudinal incision 4 are connected and the directions are perpendicular to each other, and the puncture along the transverse incision 3 The middle of the piercing is pierced inward, and then it can enter the longitudinal incision 4 along the way, and the piercing is more convenient. Compared with non-channel and one-way channel isolation plugs, it is more labor-saving and does not generate debris that can affect injection. The sealing effect is good. The top and bottom of the isolation plug body 1 adopt two incisions that are perpendicular to each other. The isolation effect is better. Compared with the one-way channel that penetrates directly, the entry of bacteria and viruses is avoided. And after the puncture is completed, the incision can quickly rebound, avoiding the difficult recovery of the puncture caused by direct puncture. The connection is tight, and the inwardly recessed connection groove 2 is provided to facilitate the introduction of the isolation plug body 1 into the catheter, and sealant can be injected after the introduction to achieve effective sealing.
