Abstract
A kind of automatic stationary type puncture casing, comprise puncture casing, described puncture casing outer cover is equipped with an air bag, described air bag is provided with air inlet, described air bag is hollow cylinder when not working, the length of described air bag is greater than the thickness of site of puncture tissue, and the two ends deformation coefficient of described air bag is large, middle part deformation coefficient is little, presents " work " font after making airbag aeration.This patent structure is simple, easy to operate, prevent puncture casing to be shifted and produce Accessory injury.
Description
Technical field
This utility model relates to a kind of automatic stationary type puncture casing.
Background technology
Existing puncture casing thrusts after in body, puncture casing may be caused to damage deep tissue for puncture casing displacement or puncture casing deviates from body cavity, therefore preventing puncture casing to be shifted or to fix puncture casing is the technical problem that each puncture casing will solve, and existing fixing puncture casing method is all adopt the mode increasing the frictional force that puncture casing is organized with perforation, such as add a few screw threads at puncture casing external diameter or form matsurface, although but adopt this mode increasing frictional force can play fixing effect, but add the damage of puncture casing to surrounding tissue simultaneously.In addition, need to carry out ventilation supercharging in body due to during puncture, and existing fixed form is all that localized contact is fixed due to what adopt, pressed gas is easily entered from unsealing and subcutaneously causes subcutaneous emphysema, thus secondary injury is caused to patient, be therefore badly in need of improving existing puncture casing.
Utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art the automatic stationary type puncture casing that a kind of structure is simple, easy to operate, prevent puncture casing displacement and generation Accessory injury.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of automatic stationary type puncture casing, comprise puncture casing, described puncture casing outer cover is equipped with an air bag, described air bag is provided with air inlet, described air bag is hollow cylinder when not working, the length of described air bag is greater than the thickness of site of puncture tissue, and when air bag is worked, the two ends of air bag are arranged on outside tissue.
The two ends deformation coefficient of described air bag is large, middle part deformation coefficient is little, presents " work " font after making airbag aeration.
The air inlet of described air bag is arranged on the end in body, and described air inlet is provided with the retainer ring being strutted by described air inlet and keep air inlet port size.
As the another kind of embodiment of this patent, the air inlet of described air bag is arranged on not to be gone up near external end, and described air inlet is connected with aerating device by pipeline.
Owing to adopting such scheme, this device adopts outside puncture casing, arranges an air bag, air bag head end arranges an air inlet, middle part due to air bag is placed in tissue and contact tissue, therefore the pressure be subject to is large, and the two ends of air bag are arranged on outside tissue, be not under pressure, therefore air bag more easily swells at two ends when inflating, thus thrust after in body at puncture casing, the demi-inflation of two ends outside tissue of air bag, air bag is made to form " work " character form structure, thus well fix puncture casing, and the middle part of air bag is also the position with contact tissue, also prevent excessive expansion to the damage of surrounding tissue simultaneously, and the two ends deformation coefficient of air bag is large, deformation coefficient in middle part is little, airbag gas is made more easily to enter into the both ends of air bag, the air inlet of this device can be arranged on air bag and also can be arranged on the end in body near external end, when air inlet is arranged on external, directly by aerating device to airbag aeration, when air inlet is arranged in vivo, air inlet arranges the size that a retainer ring fixes air inlet, thus utilize during puncture and pass into pressed gas in body air bag is inflated, the step to air bag manual inflation can be saved like this, improve the efficiency of puncture.
In sum, this device utilizes puncture casing to be gas transluminal operation manual inflation, completes the automatic inflating of air bag; Also use puncture casing be greater than with tissue contacting portions pressure and organizing discontiguous part, gas is made more to enter air bag outside tissue, the namely two ends of air bag, balloon ends is expanded and automatically forms " work " shape structure, body wall is clamped by the two ends of " work " shape structure, thus firm fixing puncture casing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state figure of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, further describe the detailed description of the invention of this patent.
As shown in Figure 1, a kind of automatic stationary type puncture casing, comprise puncture casing 1, described puncture casing 1 outer cover is equipped with an air bag 2, and described air bag 2 is provided with air inlet 3, air inlet 3 when venting also simultaneously as gas outlet, described air bag 2 is hollow cylinder when not working, the length of described air bag 2 is greater than the thickness of site of puncture tissue, and the two ends deformation coefficient of described air bag 2 is large, middle part deformation coefficient is little, presents " work " font after air bag 2 is inflated.
As a kind of embodiment of this patent, the air inlet of described air bag 2 is arranged on the end in body, and described air inlet is provided with the retainer ring being strutted by described air inlet and keep air inlet port size.
As the another kind of embodiment of this patent, the air inlet of described air bag is arranged on not to be gone up near external end, and described air inlet is connected with aerating device by pipeline.
As shown in Figure 2, during use, when the air inlet of described air bag 2 is arranged on the end in body, first puncture casing 1 is thrust after in body, air bag 2 is entered from air inlet under the pressure of air bag 2 gas in vivo, first the part of air bag 2 outside tissue 4 expand, air bag is made to form " work " character form structure, thus puncture casing 1 is fixed in tissue 4, prevent puncture casing 1 mobile in tissue, and the medium position of air bag plays a part to support to tissue 4, thus prevent excessive expansion to the damage of surrounding tissue, when puncture casing 1 takes out by needs, first the gas passed in body is discharged, air bag 2 is not owing to having the support of pressed gas simultaneously, thus return to original hollow cylinder, now direct puncture casing 1 to be taken out.
