Abstract

The utility model relates to a fixing mechanism for thoracoabdominal puncture that is safe and reliable, firmly fixed with simple structure and easy access, applicable to discharging the accumulated air or liquid in the thoracic cavity or abdominal cavity of patients, and characterized in that a rubber balloon with a drum open at one side is arranged; a hopper-shaped sorption ring is built in the open of the rubber balloon; a binding rod is sheathed at the outside of the thin neck of the sorption ring; a shrink-ring is positioned at the upper end of the binding rod while a sleeve gasket ring with a rubber gasket built-in is arranged at the lower end of the binding rod. The utility model can make the puncture needle penetrating through the rubber gasket. In case the sorption ring is close to the skin surface, part of the air in the balloon can be removed by pressing the rubber balloon. And then, the sorption ring will be tied to the skin firmly. Fixation of puncture is maintained by the negative pressure absorption applied to skin from the rubber balloon.

Description

Splanchnocoel puncture fixture

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of splanchnocoel puncture fixture.

Background technology

At present, clinical liquid, pneumothorax sting device are made up of common syringe needle (No. 8 or No. 9) or piercing needle, drain connection tube and the mosquito forceps more longer than common syringe needle, drain connection tube one termination pintle (being generally 50ml), another termination piercing needle, mosquito forceps are extracted the liquid in patient's breast abdomen, gas out at needle tubing and are clamped the drain connection tube when effluxing in case stop ring border gas enters the patient thoracic cavity along the drain connection tube.Said process puncture needle when practical operation is difficult for fixing, poor safety performance, someone designs the holder that is used for fixing puncture needle, holder comprises the screw fixed device, auxiliary fixedly spiral and the structure hook that matches with it, fixing band, wherein screw fixed device and auxiliary fixedly spiral all have female thread, corresponding with the external screw thread on the puncture needle, make it and to move along the puncture spiral, thereby the adjusting paracentesis depth also has four symmetric circular holes on the screw fixed device, and it is cared for mutually with hook one end, the other end of hook is then cared for fixing band, thereby plays the fixedly effect of puncture needle jointly.This design complex structure, troublesome poeration, and fixing not firm.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, easy to operate, fixation, safe and reliable splanchnocoel puncture fixture.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of splanchnocoel puncture fixture, the rubber pocket that has cylindric opening comprising a side, it is characterized in that: be inlaid with funnelform absorption ring in the opening of rubber pocket, the thin neck of absorption ring is with connecting rod outward, the upper end of connecting rod has the cover ring, the lower end has the cover packing ring, is with rubber blanket in the cover packing ring.

This utility model can pass puncture needle from rubber blanket, when the absorption ring is close to the human body skin surface, the extruding rubber pocket is got rid of portion gas wherein, the then firm suction of absorption ring is attached on the skin, realize the fixing, simple in structure, easy to operate, safe and reliable of puncture needle by the negative-pressure adsorption of rubber pocket on skin.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is further described:

A kind of splanchnocoel puncture fixture, as shown in Figure 1, the rubber pocket 1 that has cylindric opening comprising a side, be inlaid with funnelform absorption ring 2 in the opening of rubber pocket 1, referring to Fig. 2, the thin neck of absorption ring 2 is with connecting rod 3 outward, and the upper end of connecting rod 3 has cover ring 31, the lower end has cover packing ring 32, is with rubber blanket 4 in the cover packing ring 32.

In this utility model, rubber pocket is called the puncture needle holder with the coalition of absorption ring, the puncture needle holder is connected with puncture needle by connecting rod, rubber blanket, the cover ring of connecting rod holds the narrow neck part that is fixed on funnel-form absorption ring, be close to the cylindric opening of rubber pocket thereafter, the cover packing ring of connecting rod surrounds on the syringe needle of puncture needle during use, and referring to Fig. 3, and there have the ring-shaped rubber pad to strengthen between the two to be fixing.

The rubber pocket that plays the negative-pressure adsorption effect in this utility model is with ordinary rubber or plastic production, it is that elasticity will be got well that quality requires, be embedded in to rise in the cylindric opening of rubber pocket one side and strengthen adsorbing absorption ring, it is hard that quality is wanted, metal, nonmetallic materials all can be made, generally be advisable with metallic article, rubber blanket is that make preferably by rubber or plastic or other material for elasticity.

Absorption ring in this utility model is a funnel-form, and the end that bore is bigger is in the cylindric opening part of rubber pocket, to increase the adsorption area to skin, strengthens steadiness, and the less end of bore is embedded in the cylindric opening of rubber pocket, with anti-gas-leak.The cover ring of connecting rod closely is looped around a thinner end of absorption ring, is close to the cylindric opening of rubber pocket thereafter, and the external diameter of absorption ring tubule should be a bit larger tham the cylindric opening internal diameter of rubber pocket, with anti-gas-leak.For connecting rod and absorption ring are connected firmly, be difficult for sliding, the absorption ring is gone up corresponding site also can add valve rubber.The cover packing ring of connecting rod links together by the syringe needle of valve rubber and puncture needle, and the syringe needle of puncture needle can slide in the middle of cyclic rubber blanket, so that the nutriture according to the patient is regulated the degree of depth that puncture needle thrusts the thoracic cavity, so both avoided thrusting the arteries and veins device damage that may cause deeply, the arteries and veins device damage of having avoided the piercing needle swing to cause again.

The right hand is held the needle handle of puncture needle during this utility model operation, left hand is held rubber pocket, make the easy positions of adsorbing of human body such as absorption ring alignment ribs gap, on selected point of puncture, allow the vertical surface inserting needle of needle point of puncture needle, when being close to skin, the absorption ring stops to carry out, left hand extruding rubber pocket makes the absorption of puncture needle holder fixing, carries out repeat aspiration then, until taking out most pneumatosis or hydrops.

This utility model can be used for not only that bleed in thoracic cavity, abdominal paracentesis, drawing liquid, also can be used for the puncture of bladder, and to thoracic cavity, intraperitoneal transfusion treatment.This utility model is with low cost, reasonable in design, fixation, safe and reliable, easy to operate, be convenient to clinical expansion and use.
