The utility model will now be described in further detail by way of specific examples of embodiments in connection with the accompanying drawings.

Referring to fig. 1, an embodiment of the present application provides a subcutaneous drainage device, including: the air bag 102 and the drainage tube 101, one side of the air bag 102 is provided with a first valve 103 which can not only allow liquid to enter and exit, one side of the air bag 102 is provided with a second valve 104 which can not only allow gas to enter and exit, and the air inlet end of the first valve 103 is connected with the drainage tube 101.

The embodiment of the application provides a subcutaneous drainage device, when the subcutaneous drainage device is used, medical staff can embed a drainage tube 101 under the skin of a patient and manually squeeze an air bag 102, and as the second valve 104 only does not enter air, the air in the air bag 102 can be discharged out of the air bag 102 to form negative pressure in the air bag 102. At this time, after the medical staff loosens hands, as the first valve 103 only cannot be in or out, the subcutaneous pus, blood and effusion can be gradually sucked into the air bag 102 through the drainage tube 101 within a longer period of time until no negative pressure exists in the air bag 102, the medical staff does not need to be repeatedly pricked into the skin to drain at intervals by using the injector, the pain of a patient is reduced, the operation flow of the patient is saved, and the cost is low. In addition, the subcutaneous drainage device is small and exquisite, and does not influence the movement of patients.

In addition, the exhaust end of the second valve 104 may be provided with a piston 106. Thus, when the air in the air bag 102 is discharged out of the air bag 102 to form negative pressure in the air bag 102, the medical staff can close the piston 106 to avoid the pollution caused by the pus, the blood and the effusion sucked into the air bag 102 penetrating into the outside through the second valve 104.

The liquid inlet end of the first valve 103 is connected with a connector 105, and the drainage tube 101 is detachably connected with the liquid inlet end of the first valve 103 through the connector 105. Thus, when the pus, blood and effusion in the air bag 102 are filled, the air bag 102 can be replaced without embedding a new drainage tube under the skin of the patient, thereby reducing the pain of the patient.

The airbag 102 is a transparent airbag, and graduation marks are arranged on the outer side of the transparent airbag. Thus, the medical staff can browse the volume of pus, blood and effusion in the transparent air bag, so that the medical staff can know the condition of the patient deeply.

Specifically, the diameter of the draft tube 101 has a value ranging from 0.2mm to 0.4mm. Such as 0.2mm, 0.3mm, and 0.4mm, etc., are not limited herein.

As shown in fig. 2 and 3, a control box 108 is provided outside the airbag 102, a controller 112 is provided inside the control box 108, a display screen 109 is provided outside the control box 108, an air pressure sensor 110 is provided inside the airbag 102, and the controller 112 is electrically connected to the air pressure sensor 110 and the display screen 109, respectively. The air pressure sensor 110 is used for acquiring air pressure signals inside the air bag 102, and the controller 112 is used for converting the air pressure signals acquired by the air pressure sensor 110 into air pressure values and outputting the air pressure values to the display screen 109 for display. In this way, the medical staff can control the air pressure value in the air bag 102 through the illness state of the patient and the air pressure value in the air bag 102 displayed by the display screen 109, so that the situation that the negative pressure of the air bag 102 is too high to cause the excessive absorption of the subcutaneous fresh blood of the patient or the situation that the negative pressure in the air bag 102 is too low to cause the complete absorption of the subcutaneous pus, blood and effusion of the patient can not be realized at one time is avoided.

In addition, as shown in fig. 2 and 3, a flow meter 107 is further provided on one side of the first valve 103, and the controller 112 is further electrically connected to the flow meter 107. The flowmeter 107 is used for detecting flow signals of pus, blood, effusion and the like flowing through the first valve 103, and the controller 112 is used for converting the flow signals collected by the flowmeter 107 into flow values and outputting the flow values to the display screen 109 for display, so that medical staff can browse the flow values, and the medical staff can know the illness state of the patient deeply.

A liquid sensor 111 is arranged in the air bag 102 at one side close to the second valve 104, an alarm 113 is also arranged in the control box 108, and the controller 112 is respectively electrically connected with the liquid sensor 111 and the alarm 113. The liquid sensor 111 is used for detecting a liquid signal, and the controller 112 is used for controlling the alarm 113 to alarm when the liquid signal is detected. Because the liquid sensor 111 is located near the side of the second valve 104, when the liquid sensor 111 detects the liquid signal, it indicates that the liquid level of pus, blood, effusion, etc. in the air bag 102 is higher, and the liquid easily permeates into the air bag 102 to cause pollution, and then the alarm 113 is controlled to alarm, so as to prompt the medical staff to process, so as to avoid pollution.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features can be replaced equivalently; such modifications and substitutions do not depart from the spirit of the application.
