Abstract

The utility model provides a thoracocentesis device which comprises an injector, guide pipes and a needle head. The guide pipes are connected with an injection port of the injector, the needle head is connected to one of the guide pipes, and a guide port is arranged on a side wall at one end of the injector, which is close to the injection port; a first one-way valve is arranged at the position of the guide port and connected with a guide bag through a first guide pipe, a second one-way valve is arranged at the position of the injection port of the injector and connected with the needle head through a second guide pipe; the needle tip portion of the needle head is an arc needle tip; and a needle rod portion of the needle head is provided with marks. According to the thoracocentesis device, the condition that the needle tip punctures lungs of patients due to the fact that the depth of acupuncture is not easy to control is effectively avoided; and simultaneously, the injector is not required for taking down to achieve a function of continuously drawing body fluids, the cumbersome degree of working is greatly reduced, and the working efficiency is improved.

Description

A kind of thoracic puncture set

Technical field

The utility model relates to a kind of medical instruments, especially a kind of thoracentesis device.

Background technology

In the prior art; Technique known is when doing thoracentesis and extract intrathoracic body fluid, to use syringe to connect mozzle one end, and the mozzle other end connects syringe needle, and syringe needle thrusts the thoracic cavity and spurs syringe again and extract body fluid out; But need take off syringe after taking out a full body liquid at every turn; Carry out second decimation with refilling syringe after the discharge of the body fluid in the syringe, step is loaded down with trivial details relatively, inefficiency; And syringe needle is the conventional pointed syringe needle that uses, and stabs patient pulmonary easily, and the degree of depth of having an acupuncture treatment is simultaneously leaned on doctors experience control entirely, safety inadequately, and this is the existing in prior technology weak point.

Summary of the invention

The purpose of this utility model is exactly not enough to existing in prior technology, is provided with draining hole and provide a kind of technical scheme of thoracic puncture set, this scheme to be employed in syringe near the sidewall of an end of injection port; Draining hole is provided with the first single-pass valve, and the first one-way valve door is connected with drainage bag through first mozzle; The injection port of syringe is provided with the second single-pass valve, and the second one-way valve door is connected with syringe needle through second mozzle; The tip portion of syringe needle is the arc needle point; It is wayward that the shank of syringe needle partly is provided with the scale degree of depth of can avoiding effectively having an acupuncture treatment, and needle point is stabbed the situation of patient pulmonary; Can also need not take off simultaneously syringe and realize the function of continuous drawing body fluid, reduce the fussy degree of work widely, improve work efficiency.

This programme is realized through following technical measures: a kind of thoracic puncture set, include syringe, and be connected the mozzle of injector to inject mouth and be connected the syringe needle on the mozzle, syringe is provided with draining hole near the sidewall of an end of injection port; Draining hole is provided with the first single-pass valve; The first one-way valve door is connected with drainage bag through first mozzle; The first single-pass valve closes when extracting bodily fluid; Take out when promoting the body fluid in the injector handle exhaustjet device behind the full body liquid, the body fluid in the first single-pass valve open, syringe just can flow into drainage bag through draining hole; The injection port of syringe is provided with the second single-pass valve; The second one-way valve door is connected with syringe needle through second mozzle, when extracting bodily fluid, and the second single-pass valve open; Body fluid in the front is drawn in the syringe; During body fluid in the exhaustjet device, the second single-pass valve closes prevents that body fluid is back in the thoracic cavity, has guaranteed that the body fluid in the syringe flows in the drainage bag through draining hole; The tip portion of said syringe needle is the arc needle point, can reduce the sharpness of needle point relatively, prevents that needle point from stabbing patient pulmonary; The shank of said syringe needle partly is provided with scale, can play the effect of the control acupuncture treatment degree of depth effectively.

The beneficial effect of this programme can learn according to the narration to such scheme, because syringe is provided with draining hole near the sidewall of an end of injection port in this scheme; Draining hole is provided with the first single-pass valve; The first one-way valve door is connected with drainage bag through first mozzle; The first single-pass valve closes when extracting bodily fluid; Take out when promoting the body fluid in the injector handle exhaustjet device behind the full body liquid, the body fluid in the first single-pass valve open, syringe just can flow into drainage bag through draining hole; The injection port of syringe is provided with the second single-pass valve; The second one-way valve door is connected with syringe needle through second mozzle, when extracting bodily fluid, and the second single-pass valve open; Body fluid in the front is drawn in the syringe; During body fluid in the exhaustjet device, the second single-pass valve closes prevents that body fluid is back in the thoracic cavity, has guaranteed that the body fluid in the syringe flows in the drainage bag through draining hole; The tip portion of said syringe needle is the arc needle point, can reduce the sharpness of needle point relatively, prevents that needle point from stabbing patient pulmonary; The shank of said syringe needle partly is provided with scale, can play the effect of the control acupuncture treatment degree of depth effectively.

This shows that this utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Description of drawings

Fig. 1 is the structural representation of this utility model specific embodiment.

Among the figure, 1 is syringe, and 2 is handle, and 3 is drainage bag, and 4 is first mozzle, and 5 is draining hole, and 6 is the first single-pass valve, and 7 is injection port, and 8 is the second single-pass valve, and 9 is second mozzle, and 10 is the arc needle point, and 11 is scale.

The specific embodiment

For clearly demonstrating the technical characterstic of this programme, below through a specific embodiment, and combine its accompanying drawing, this programme is set forth.

Can find out that through accompanying drawing this programme syringe 1 is provided with draining hole 5 near the sidewall of an end of injection port 7; Draining hole 5 is provided with the first single-pass valve 6; The first single-pass valve 6 is connected with drainage bag 3 through first mozzle 4; The first single-pass valve, 6 closures when extracting bodily fluid; When taking out the body fluid in the handle 2 exhaustjet devices 1 of pushing syringe 1 behind the full body liquid, the first single-pass valve 6 is opened, and the body fluid in the syringe 1 just can flow into drainage bags 3 through draining hole 5; The injection port 7 of syringe 1 is provided with the second single-pass valve 8; The second single-pass valve 8 is connected with syringe needle through second mozzle 9, and when extracting bodily fluid, the second single-pass valve 8 is opened; Body fluid in the front is drawn in the syringe 1; During body fluid in exhaustjet device 1, the second single-pass valve, 8 closures prevent that body fluid is back in the thoracic cavity, have guaranteed that the body fluid in the syringe 1 flows in the drainage bags 3 through draining hole 5; The tip portion of said syringe needle is an arc needle point 10, can reduce the sharpness of needle point relatively, prevents that needle point from stabbing patient pulmonary; The shank of said syringe needle partly is provided with scale 11, can play the effect of the control acupuncture treatment degree of depth effectively.
