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

Background

A disposable indwelling needle consists of a protective sleeve, a catheter component, a needle tube component, a hose component, a heparin cap, a water stop clip, 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 remove air bubbles, a part suitable for puncture is selected, after disinfection according to a conventional method, the vein is punctured, after blood return is seen, the catheter is fed into the vein while the puncture needle tube is pulled out, finally the puncture needle tube is completely pulled out, the catheter is retained in the vein and fixed well, and then multiple times of infusion can be carried out on the patient, the sealing isolation plug plays a role of sealing isolation, external bacteria and viruses can be isolated, the entry into the catheter is avoided, therefore, performance which is very important for whether the sealing performance of the sealing isolation plug after multiple times of puncture is still good or not, in the production process of the existing venous indwelling needle isolation plug, serious incision production and serious assembly of the phenomenon of the puncture needle drop are caused, and the possibility of the puncture needle insertion hole or the possibility of the cross-caused by the puncture of the puncture needle or the increase of the possibility of the puncture of the medical care and the formation of a puncture needle caused by the puncture needle or the increase of the possibility of the puncture needle assembly caused by the cross-caused by the puncture needle or the puncture needle assembly caused by the puncture needle assembly and the increase of the puncture needle assembly.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides novel sealing isolation plugs, which reserve a bidirectional channel, are convenient for puncture by a puncture needle and can maintain good sealing performance after multiple punctures.

In order to solve the problems in the prior art, the invention discloses novel sealing isolation plugs, which comprise an isolation plug body, wherein the middle part of the isolation plug body is provided with a connecting groove which is sunken towards the center line of the isolation plug body, the top of the isolation plug body is provided with a transverse cut, the transverse cut extends downwards from the top of the isolation plug body to the position corresponding to the connecting groove on the isolation plug body, the bottom of the isolation plug body is provided with a longitudinal cut, the longitudinal cut extends upwards from the bottom of the isolation plug body to the position corresponding to the connecting groove on the isolation plug body, and the transverse cut and the longitudinal cut are connected at the position corresponding to the connecting groove on the isolation plug body.

Preferably, the width of the transverse cuts and the width of the longitudinal cuts are smaller than the minimum diameter of the isolating plug body.

Preferably, the transverse cuts and the longitudinal cuts have a width .

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

Preferably, the depth of the inward recess of the connecting groove is smaller than the radius of the position of the connecting groove.

The invention has the beneficial effects that: the puncture is convenient, sets up horizontal incision and longitudinal incision respectively at the top and the bottom of isolation stopper body, and horizontal incision meets and the direction mutually perpendicular with longitudinal incision, pierces inwards along the middle part of horizontal incision during the puncture, alright in order entering into longitudinal incision, it is more convenient to puncture. Compared with the isolating plug without the channel and the one-way channel, the isolating plug saves more labor and does not generate scraps to influence injection. Sealed effectual, adopt mutually perpendicular's twice incision at the top of isolation stopper body and bottom, it is better to keep apart the effect, compares with the one-way passage that directly runs through, avoids the bacterium virus to get into. And after the puncture is finished, the incision can be rebounded quickly, so that the situation that the puncture hole is difficult to recover due to direct puncture is avoided. Connect closely, set up inside sunken spread groove, the isolation stopper body of being convenient for is leading-in to the inside of guide tube to can pour into sealed glue etc. and realize effective sealing after leading-in.

Detailed Description

The present invention is further described in conjunction with the drawings the following examples are provided to more clearly illustrate the structure of the present invention.

novel sealing isolation plug comprises an isolation plug body 1, wherein the middle part of the isolation plug body 1 is provided with connecting groove 2, the connecting groove 2 is sunken towards the center line of the isolation plug body 1, the top of the isolation plug body 1 is provided with a transverse cut 3, the transverse cut 3 extends downwards from the top of the isolation plug body 1 to the position corresponding to the connecting groove 2 on the isolation plug body 1, the bottom of the isolation plug body 1 is provided with a longitudinal cut 4, the longitudinal cut 4 extends upwards from the bottom of the isolation plug body 1 to the position corresponding to the connecting groove 2 on the isolation plug body 1, and the transverse cut 3 and the longitudinal cut 4 are connected at the position corresponding to the connecting groove 2 on the isolation plug body 1.

The width of the transverse cuts 3 and the width of the longitudinal cuts 4 are smaller than the minimum diameter of the isolation plug body 1, and the width of the transverse cuts 3 and the width of the longitudinal cuts 4 are equal to the width of the transverse cuts 3, so that the transverse cuts 3 and the longitudinal cuts 4 are perpendicular to each other.

The depth of the inward recess of the connecting groove 2 is smaller than the radius of the position of the connecting groove 2.

The invention has the beneficial effects that: the puncture is convenient, sets up horizontal incision 3 and longitudinal incision 4 respectively at the top and the bottom of isolation stopper body 1, and horizontal incision 3 meets and the direction mutually perpendicular with longitudinal incision 4, pierces inwards along the middle part of horizontal incision 3 during the puncture, alright in 4 with entering into longitudinal incision along, it is more convenient to puncture. Compared with the isolating plug without the channel and the one-way channel, the isolating plug saves more labor and does not generate scraps to influence injection. Sealed effectual, adopt mutually perpendicular's twice incision at the top of isolation stopper body 1 and bottom, it is better to keep apart the effect, compares with the one-way passage that directly runs through, avoids the bacterium virus to get into. And after the puncture is finished, the incision can be rebounded quickly, so that the situation that the puncture hole is difficult to recover due to direct puncture is avoided. Connect closely, set up inside sunken connecting groove 2, the isolation stopper body 1 of being convenient for is leading-in to the inside of the guide tube to can pour into sealed glue etc. and realize effective sealing after leading-in.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
