Abstract
The utility model relates to a medical appliance, especially to a disposable thoracentesis sucking device. The sucking device comprises a needle, a rubber hose, a syringe cylinder, and a one-way valve, wherein the needle is communicated with the one-way valve via the rubber hose, the one-way valve is communicated with the syringe cylinder via the rubber hose, and the one-way valve is in an OFF state normally. The one-way valve is equipped with a spring and a rubber ball, wherein one end of the spring is connected with the inner wall of the one-way valve and the other end of the spring is connected with the rubber ball. The disposable theoracentesis sucking device of the utility model overcomes the disadvantage that with traditional disposable theoracentesis sucking devices, external air tends to enter the thoracic cavity of a patient when a syringe cylinder is changed during the sucking process, thereby achieving certain beneficial effects.
Description
Technical field
This utility model relates to a kind of medical apparatus, especially a kind of disposable thoracentesis aspirator.
Background technology
Traditional disposable thoracentesis aspirator is made up of syringe needle, rubber hose, syringe and hemostatic clamp; When in aspiration procedure, changing syringe; Regular meeting occurs introducing harmful effect because medical personnel use the untimely ambient atmos that causes of hemostatic clamp blocking-up rubber hose to get in the patient thoracic cavity.
The utility model content
This utility model is intended to address the above problem; A kind of disposable thoracentesis aspirator is provided; It has overcome, and ambient atmos is prone to cause dysgenic drawback in the entering patient thoracic cavity when changing syringe in traditional disposable thoracentesis aspirator aspiration procedure, and its technical scheme that adopts is following:
A kind of disposable thoracentesis aspirator; Comprise syringe needle, rubber hose, syringe; This disposable thoracentesis aspirator also comprises a check valve; Said syringe needle is communicated with check valve through rubber hose, and said check valve is communicated with syringe through rubber hose, and said check valve is in closure state under normal conditions.
On the technique scheme basis, be provided with spring and ball in the said check valve, an end of said spring is connected the other end with the check valve inwall and is connected with ball.
The utlity model has following advantage: simple in structure, easy to use, cost of manufacture is low, can effectively avoid when changing syringe ambient atmos to get in the patient thoracic cavity and cause harmful effect.
Description of drawings
Fig. 1: the structural representation of this utility model (band part section);
Symbol description:
1. syringe needle, 2. rubber hose, 3. check valve, 4. syringe, 5. ball, 6. spring.
The specific embodiment
Below in conjunction with accompanying drawing and instance this utility model is described further:
As shown in Figure 1; A kind of disposable thoracentesis aspirator of present embodiment; Comprise syringe needle 1, rubber hose 2, syringe 4, this disposable thoracentesis aspirator also comprises a check valve 3, and said syringe needle 1 is communicated with check valve 3 through rubber hose 2; Said check valve 3 is communicated with syringe 4 through rubber hose 2, and said check valve 3 is in closure state under normal conditions.
Preferably, be provided with spring 6 and ball 5 in the said check valve 3, an end of said spring 6 is connected the other end with check valve 3 inwalls and is connected with ball 5.
In use, syringe 4 is connected with check valve 3 through rubber hose 2, syringe needle 1 is thrust in the patient thoracic cavity; Drawing syringe 4, spring 6 shrinks, thus ball 5 is left the air inlet of check valve 3 and is drawn pneumatosis or hydrops in the thoracic cavity; After treating that syringe 4 capacity are used up, extract syringe 4, spring 6 stretches automatically; The air inlet that promotion ball 5 compresses check valve 3 makes extraneous isolated with the thoracic cavity; Thereby guaranteed that ambient atmos can not get in the thoracic cavity, changed new syringe 4 a continued suction hydrops or a pneumatosis then, accomplished until work.
With way of example this utility model is illustrated above, but this utility model is not limited to above-mentioned specific embodiment, all any changes done based on this utility model or modification all belong to this utility model and require the scope protected.
