The specific embodiment
Below, will and coordinate accompanying drawing by some concrete embodiment, thoracentesis drainage device described in the utility model is described below in detail:
Fig. 1 is the front view of this utility model the first specific embodiment.As shown in the figure, thoracentesis drainage device described in the utility model comprises syringe 1 and the drainage bag 4 that is connected with syringe 1 by drainage tube 3.In the present embodiment, syringe 1 is basic identical with the structure of common syringe, comprises puncture needle 11, syringe 10 and needle handle 12.Wherein, drainage tube 3, for seamless link or integrally formed, with the seal of intensifier, thereby reduces the generation of polluting with drainage bag 4.In addition, for the hydrops with in syringe 10, thoroughly discharge, drainage tube 3 is arranged near puncture needle 11 places.Further, be provided with at least two check valves on described syringe 10, namely in described syringe 10 and the junction of puncture needle 11, be provided with the first check valve 2A, in syringe 10 and the junction of drainage tube 3, be provided with the 3rd check valve 2C.
Further, as shown in Figure 3, described the first check valve 2A and the 3rd check valve 2C comprise that respectively central authorities are provided with the fixture 21 of through hole 23, and are movably connected in the diaphragm seal 22 that can open to a side on fixture 21, and the diameter of described diaphragm seal 22 is greater than the diameter of through hole 23.When described the first check valve 2A or the 3rd check valve 2C were in closure state, diaphragm seal 22 was to cover through hole 23 fully.
Again further, the diaphragm seal 22 of described the first check valve 2A is positioned at the inboard of syringe 10, and namely sealing sheet 22 only can be opened towards the inside of syringe 10, completes breakdown action.The diaphragm seal 22 of the 3rd check valve 2C is positioned at the outside of syringe 10, and namely sealing sheet 22 only can, towards the external opening of syringe 10, be completed breakdown action.So that described device is realized the function of liquid one-way flow.
When extracting hydrops, pull the needle handle 12 of syringe 1, under the effect of pressure differential, the first check valve 2A opens, and is opening.Simultaneously, the 3rd check valve 2C is in closure state, and further, the 3rd check valve 2C is arranged near puncture needle 11 places.So, making the intrathoracic hydrops of patient be introduced into syringe 10 and be detained can not leak outside therein.When the hydrops in syringe 10 arrives the maximum of syringe 10 scales, the operator can promote needle handle 12, and at this moment, the first check valve 2A becomes closure state under the effect of pressure differential, the 3rd check valve 2C transfers opening to, thereby makes the hydrops in syringe 10 flow into drainage bag 4 through drainage tube 3.So, just, completed a drawing liquid operation.The operator can repeatedly repeat above-mentioned drawing and promote to do, and, until the intrathoracic hydrops of patient is extracted totally, then extracts puncture needle 11, and then completes whole drawing liquid operation.
As shown in Figure 2, it is the front view of this utility model the second specific embodiment.As shown in the figure, the first check valve 2A is identical with set position in the first embodiment.The difference of the present embodiment and the first embodiment is: in the present embodiment, syringe 10 is double side walls, and it comprises inner layer wall 101 and outer wall 102, is formed with a cavity volume between the two.For the hydrops with in syringe 10 is thoroughly discharged, drainage tube 3 is arranged on the bottom of described outer wall 102 near needle handle 12 places.In addition, be provided with the second check valve 2B near puncture needle 11 on described inner layer wall 101, the present embodiment be two the second check valve 2B that are oppositely arranged be that example is described.Yet the number of the second check valve 2B on described inner layer wall 101 and setting position be not as limit.
Further, as shown in Figure 3, described the first check valve 2A and the second check valve 2B comprise that respectively central authorities are provided with the fixture 21 of through hole 23, and are movably connected in the diaphragm seal 22 that can open to a side on fixture 21, and the diameter of described diaphragm seal 22 is greater than the diameter of through hole 23.When described the first check valve 2A or the second check valve 2B were in closure state, diaphragm seal 22 was to cover through hole 23 fully.
Further, the diaphragm seal 22 of described the first check valve 2A is positioned at the inboard of syringe 10, and namely sealing sheet 22 only can be opened towards the inside of syringe 10, completes breakdown action.The diaphragm seal 22 of the second check valve 2B is positioned at cavity volume, and namely sealing sheet 22 only can be opened towards outer wall 102, completes breakdown action.So that described device is realized the function of liquid one-way flow.
When extracting hydrops, the operator can pull the needle handle 12 of syringe 1, and this moment, syringe 10 was opened with the first check valve 2A of puncture needle 11 junctions, is opening under the effect of pressure differential.Simultaneously, the second check valve 2B that arranges near puncture needle 11 on syringe 10 inner layer walls 101 is in closure state.So, making the intrathoracic hydrops of patient be introduced into syringe 10 and be detained can not leak outside therein.When the hydrops in syringe 10 arrives the maximum of syringe 10 scales, the operator can promote needle handle 12, at this moment, the first check valve 2A becomes closure state under the effect of pressure differential, the second check valve 2B transfers opening to, thereby make the hydrops in syringe 10 first flow to cavity volume, then by drainage tube 3, flow in drainage bag 4.So, just, completed a drawing liquid operation.The operator can repeatedly repeat above-mentioned drawing and promote to do, and, until the intrathoracic hydrops of patient is extracted totally, then extracts puncture needle 11, and then completes whole drawing liquid operation.
Can be understood as, this utility model is described by some embodiment, and those skilled in the art are in the situation that break away from spirit and scope of the present utility model, can to these features and embodiment carry out various changes or equivalence is replaced.In addition, under instruction of the present utility model, can modify to adapt to concrete situation and material and can not break away from spirit and scope of the present utility model these features and embodiment.Therefore, this utility model is not subjected to the restriction of specific embodiment disclosed herein, and all interior embodiment of claim scope that fall into the application belong to protection domain of the present utility model.
