Abstract
The utility model relates to a multi-function thoracentesis device which is composed of an air (liquid) drainage pipe, an air (liquid) suction pipe, a passage behind a valve, a check valve embolism, a passage in front of the valve, an injector connector, and a thoracentesis device body. The air (liquid) drainage pipe, the air (liquid) suction pipe, and the thoracentesis device body are tightly matched, and the air (liquid) leakage is eliminated. The check valve embolism is an assembly of a cone and a cylinder, the conicity of the cone is identical with the conicities of the thoracentesis device body and the round table cavity of the air (liquid) suction pipe, a cavity of the cone and cylinder assembly is retained in the check valve embolism, and four gaps are arranged at the terminal of the check valve embolism.
Description
This utility model belongs to the medical apparatus and instruments scope, relates to the improvement of thoracentesis apparatus.
Present puncture for pneumothorax and hydrothorax, general injection needle or the artificial pneumothorax apparatus that has latex tubing that adopt, in operating process, needing the assistant constantly to press from both sides with mosquito forceps closes and decontrols latex tubing or constantly rotate the artificial pneumothorax apparatus channel selector, complex operation, influence the drawing liquid speed of bleeding, also wasted manpower simultaneously.
The purpose of this utility model just provides a kind of thoracentesis device that integrates the drawing liquid function of bleeding, and it can realize the one man operation, and saving manpower and raising are bled, drawing liquid speed.
This utility model is realized as follows, at (liquid) pipe and aerofluxus (liquid) the pipe place of bleeding, a check valve respectively is set, and their switch direction is opposite.
Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing.
Fig. 1 is the sectional side elevation according to the multi-functional chest puncture instrument that the utility model proposes.
Fig. 2 is two views of check valve embolus ［ 4.5 ］ among Fig. 1.
As shown in Figure 1, this device comprises a chest puncture instrument body ［ 10 ］, a syringe connector ［ 9 ］ that links to each other with syringe, (liquid) pipe ［ 8 ］ of bleeding that is connected with piercing needle, an aerofluxus (liquid) pipe ［ 1 ］ can external latex tubing, two check valve emboluses ［ 4,5 ］.Above-mentioned two pipes ［ 1,8 ］ all tightly cooperate with chest puncture instrument body ［ 10 ］, do not have gas leakage (liquid).As shown in Figure 2, check valve embolus ［ 4,5 ］ is the assembly of circular cone and cylinder, its circular cone tapering is identical with the tapering of the round platform cavity of the chest puncture instrument body ［ 10 ］ and (liquid) pipe ［ 8 ］ of bleeding, and portion leaves a circular cone and cylinder assembly cavity within it, and end is not equipped with 4 breach.
At syringe with after this device is connected, when pull syringe bolt, under this device internal pressure is regulated, check valve embolus ［ 4 ］ is in the release position, check valve embolus ［ 5 ］ is in the closed position, and this device is in state shown in Figure 1, and aerothorax (liquid) is gone into valve prepass ［ 6 ］ by piercing needle, by the terminal breach of check valve embolus ［ 4 ］, passage behind valve ［ 2 ］ enters syringe; When advancing the syringe bolt, check valve embolus ［ 4,5 ］ on the contrary residing position and above-mentioned, gas (liquid) body in the syringe by valve prepass ［ 7 ］ by the terminal breach of check valve embolus ［ 5 ］, passage behind valve ［ 3 ］ discharge.If link to each other with pressure gauge with tee T between (liquid) pipe ［ 8 ］ and piercing needle bleeding, make the drawing liquid of bleeding under the monitoring of intrathoracic pressure, carry out better.
In addition, with after this device is connected,, replace push-and-pull syringe bolt then, still can reach the purpose of pressure transfusion if aerofluxus (liquid) pipe ［ 1 ］ of this device is linked to each other with the aerofluxus syringe needle of transfusion device at syringe.
This utility model only needs with aerofluxus (liquid) pipe place a check valve to be set respectively at (liquid) pipe of bleeding, and their switch direction is opposite, simple in structure, simultaneously because the starting point of the present utility model is to realize to bleed, the semi-automation of drawing liquid and pressure transfusion, mode of operation does not have specific (special) requirements, be easy to grasp, be easy to realize the purpose of saving manpower, raising the efficiency.
Claims (2)
