technical field

The utility model relates to the technical field of medical equipment, in particular to an effusion drainage device for thoracic surgery nursing.

Background technique

Closed thoracic drainage is to put one end of the drainage tube into the chest cavity, and the other end is connected to a water-sealed bottle lower than its position, so as to discharge gas or collect fluid in the chest cavity, so that the lung tissue can reopen and restore function. A treatment method is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases.

At present, when doctors drain the fluid inside the patient's chest cavity, in order to improve the drainage efficiency, they often use a syringe to cooperate with pumping, and a new syringe needs to be replaced every time the pump is drawn. The operation is too troublesome and the drainage efficiency is not high. Secondly, storage When the liquid in the liquid bottle is full, it cannot be found and replaced in time, which affects the normal operation of drainage.

Utility model content

The purpose of the utility model is to solve the shortcomings in the prior art, and propose a effusion drainage device for thoracic surgery nursing.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a effusion drainage device for thoracic surgery nursing, including a drainage needle and a liquid storage bottle, the inner surface wall of the top side of the liquid storage bottle is provided with a liquid A surface sensor, a buzzer is arranged on the outer wall of the top side of the liquid storage bottle, the top of the liquid storage bottle communicates with the first drainage tube through the first connecting tube, and one end of the first drainage tube communicates with a drainage steel Needle, the middle part of one side of the first connecting tube communicates with the piston barrel through the second connecting tube, the bottom side of the piston barrel communicates with the liquid storage bag through the second drainage tube, and the inside of the piston barrel is slidably sleeved There are pistons.

As a further description of the above technical solution:

The connection between the first connecting pipe and the liquid storage bottle is provided with a third one-way valve on the first connecting pipe.

As a further description of the above technical solution:

A first one-way valve and a second one-way valve are respectively provided at the central position of one side and the bottom of one side of the piston barrel.

As a further description of the above technical solution:

The central position of one side of the piston is fixedly connected with the push handle through the piston rod.

As a further description of the above technical solution:

The output end of the liquid level sensor is electrically connected with the input end of the buzzer.

In the utility model, first of all, through the cooperative arrangement of the piston cylinder, the first one-way valve and the second one-way valve, the pumping work can be continuously performed without replacing the piston cylinder. The structure is simple and the operation is convenient. It has high practicability and improves the drainage efficiency. Secondly, through the setting of the liquid level sensor and the buzzer, the liquid level of the liquid storage bottle can be monitored in real time, so that the medical staff can replace the liquid storage bottle in time to ensure the smooth drainage work conduct.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to Figures 1-3, a effusion drainage device for thoracic surgery nursing includes a drainage needle 1 and a liquid storage bottle 7, a liquid level sensor 10 is arranged on the inner wall of the top side of the liquid storage bottle 7, and the liquid storage bottle 7. A buzzer 6 is provided on the outer wall of the top side. The top of the liquid storage bottle 6 communicates with the first drainage tube 2 through the first connection tube 3, and one end of the first drainage tube 2 is connected with a drainage steel needle 1. The middle part of one side of a connecting pipe 3 communicates with the piston barrel 5 through the second connecting pipe 4, the bottom side of the piston barrel 5 communicates with the liquid storage bag 9 through the second drainage tube 8, and the piston barrel 5 is slidingly sleeved inside the piston 13.

The connection between the first connecting pipe 3 and the liquid storage bottle 7 is located on the first connecting pipe 3, and a third one-way valve 16 is arranged on the first connecting pipe 3, and a first one-way valve is arranged on the center position of one side and the bottom of one side of the piston barrel 5, respectively. 11 and the second one-way valve 12, the central position of one side of the piston 13 is fixedly connected with the push handle 15 through the piston rod 14, and the output end of the liquid level sensor 10 is electrically connected with the input end of the buzzer 6.

The first one-way valve 11, the second one-way valve 12 and the third one-way valve 16 are all used to control the one-way circulation of liquid or gas, so as to ensure that the gas and liquid inside the chest cavity can be drained smoothly. The liquid level sensor 10 is used to Monitor the height of the liquid level. When the liquid inside the liquid storage bottle 7 is full, the liquid level sensor 10 transmits an electrical signal to the buzzer 6, thereby controlling the buzzer 6 to sound a buzzer alarm, reminding the medical staff to replace the liquid storage bottle 7 in time .

Working principle: When in use, insert the drainage steel needle 1 into the chest cavity of the patient, and by pulling the push handle 15 outward, the piston 13 moves inside the piston barrel 5, thereby generating negative pressure, and sucking the liquid or gas inside the chest cavity into the piston barrel 5, then, push the push handle 15 in the reverse direction, the piston 13 moves in the reverse direction, the gas and liquid inside the piston cylinder 5 are pressed into the liquid storage bag 9 to be collected, repeat the above process, and most of the gas and liquid in the chest cavity can be discharged , and finally, through negative pressure, the residual liquid inside the thoracic cavity is slowly drained into the liquid storage bottle 7 through the first drainage tube 2, and when the liquid is full, an alarm is issued through the buzzer 6 to remind the medical staff to replace the liquid storage bottle in time 7.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
