Preferably, the binding band is an elastic band, so that the binding band is firmer and more stable.

In some alternative embodiments, the height of the screw plug 21 in the axial direction is the same as the height of the screw section and the smooth section of the cartridge 1 in the axial direction.

It will be appreciated that the purpose of the screw plug 21 is to precisely control the distance of movement of the rubber plug 22 within the cartridge. Therefore, in order to avoid the rubber plug 22 moving to the thread section of the liquid storage barrel 1, interference is caused to the cooperation of the thread plug 21 and the thread section of the liquid storage barrel 1, the thread plug 21 and the rubber plug 22 are arranged at intervals, and the axial heights of the thread plug 21 and the thread section of the liquid storage barrel 1 are the same as those of the smooth section, so that the good cooperation of the thread plug 21 and the thread section of the liquid storage barrel 1 can be ensured, and the rubber plug 22 can move within the range of the smooth section without moving to the thread section.

In some alternative embodiments, the straps include left strap 411 and right strap 412, one end of left strap 411 and right strap 412 are connected to reservoir 1, respectively, and the other ends of left strap 411 and right strap 412 are detachably connected and form a loop structure.

It will be appreciated that left strap 411 and right strap 412 cooperate to form a loop for binding at the patient's forearm, which is provided for the purpose of facilitating binding and removal.

In this example, one side of the left strap 411 is provided with a pile layer, and one side of the right strap 412 is correspondingly provided with a barb layer, thereby achieving adjustable and detachable connection of the left strap 411 and the right strap 412.

In some alternative embodiments, left strap 411 and right strap 412 are each attached to reservoir 1 by a snap fit. So as to ensure the connection stability of the left binding band 411, the right binding band 412 and the liquid storage barrel 1, and avoid the falling off of the liquid storage barrel 1 and the binding band when the wound effusion in the liquid storage barrel 1 is increased.

In some alternative embodiments, the shoulder straps 42 are adjustable in length. To adapt to different wearing requirements of patients.

In some alternative embodiments, the other end of the negative pressure control rod 2 is provided with an annular rotating handle 23, and the plane of the rotating handle 23 coincides with the axis of the negative pressure control rod 2.

The turning handle 23 is provided in a ring shape, and the plane of the turning handle 23 coincides with the axis of the negative pressure control lever 2, thereby facilitating control of the rotation of the negative pressure control lever 2 by the turning handle 23.

In this example, the rotary handle 23 has a triangular annular structure integrally formed with the negative pressure control rod 2, which is more convenient for one-hand operation and saves labor.

In some alternative embodiments, the cartridge 1 is a transparent piece of material and is provided with graduations along its height.

The liquid storage cylinder 1 is transparent, so that the volume of wound effusion in the liquid storage cylinder 1 can be conveniently observed, the volume of the effusion can be conveniently measured each time by setting the scale, and the wound condition of a patient can be conveniently known.

In some alternative embodiments, the closed end of the cartridge 1 is provided with a liquid outlet 11 and is closed by a closure.

The liquid outlet 11 is used for facilitating the drainage of wound fluid in the liquid storage barrel 1. It should be noted, however, that the closure should ensure complete closure of the outlet 11 during drainage of the wound.

The working principle of the embodiment of the utility model is as follows: the shoulder belt 42 is obliquely spanned on the shoulder of a patient, the liquid storage barrel 1 is fixed on the big arm of the patient by using the left binding belt 411 and the right binding belt 412, the rotating handle 23 is rotated, the threaded plug 21 is matched with the threaded section of the liquid storage barrel 1, the rubber plug 22 is driven to move towards the opening end of the liquid storage barrel 1 along the axial direction of the liquid storage barrel 1, and at the moment, the other end of the drainage tube 3 sucks accumulated liquid at the wound into the liquid storage barrel 1. After the suction is completed, the sealing element of the liquid outlet 11 is opened, and the accumulated liquid is discharged, so that the next use is convenient.

According to the ear wound drainage device, the screw plug and the rubber plug are arranged on the negative pressure control rod and are respectively matched with the screw section and the smooth section on the inner wall of the liquid storage barrel, so that the moving distance of the rubber plug in the liquid storage barrel can be accurately controlled by using the screw plug, the negative pressure value in the liquid storage barrel is further controlled, and discomfort to a patient during suction caused by overlarge negative pressure in the liquid storage barrel is avoided; the shoulder straps and the binding straps are arranged, so that the liquid storage barrel is stably fixed at the large arm of a patient, and the phenomenon that the drainage tube falls off or the liquid storage barrel falls off when the patient moves while carrying the liquid storage barrel is avoided; an annular rotating handle is arranged, so that the negative pressure control rod can be conveniently rotated; the liquid storage cylinder is transparent and provided with scales, so that the liquid storage cylinder is convenient to observe and extract the hydrops condition.
