Description
Technical Field
The utility model belongs to the field of medical equipment, in particular to liquid collecting device for surgical operation.
Background
The surgery is called as operation, commonly known as open surgery, and refers to a treatment process of entering human body or other biological tissues through surgical equipment or surgical instruments and operated by surgeons or other professionals to remove pathological changes, change structures or implant foreign objects by means of external force.
Surgery involves many aspects such as disease treatment, plastic face-lifting, etc.; after a patient is treated, it is often necessary to continue draining a portion of the patient's blood or fluid. The current liquid collecting device is mainly realized by a fixed air bag and a liquid guiding mechanism. When the device is used, one end of the liquid guiding mechanism is connected with the fixed air bag, and the other end of the liquid guiding mechanism is inserted into human tissues; then through the fixed gasbag of extrusion to reduce the pressure in the fixed gasbag, impel blood or hydrops to get into fixed gasbag, then extrude the hydrops or blood in the fixed gasbag to the collection dish in. However, in the process of pressing and fixing the air bag, part of the gas flows back to the human body through the liquid guiding mechanism, and the human body is easily injured.
Aiming at the problem, the liquid collecting device is improved at present and is realized by adopting an injector; the pressure is adjusted by pulling the piston rod. But in the using process, the liquid guide mechanism is easy to fall off from the injector; or when the piston rod is pulled, the pulling distance of the piston rod is not proper, and the piston rod is easy to retreat when the air pressure difference at two sides of the injector is overlarge.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a liquid collecting device for surgical operation to the realization is fixed to the stability of drain mechanism.
The liquid collecting device for the surgical operation comprises a liquid guide mechanism and a liquid collecting pipe; the liquid guiding mechanism comprises a liquid guiding pipe which is penetrated in the axial direction and a liquid guiding needle which is connected to one end of the liquid guiding pipe; the liquid collecting tube comprises a tube body with an opening at one end, a rubber plug hermetically connected to the opening of the tube body and a fixed cover in threaded connection with the tube body, and a limiting hole for the liquid guide needle to penetrate through is formed in the top of the fixed cover.

Further, the connecting rod is positioned at the top of the fixed cover. The connecting rod is arranged at the top of the fixed cover, so that the stroke of the fixed cover is increased.
Furthermore, a plug for sealing the air outlet hole is detachably connected in the air outlet hole. Through setting up the jam, can prevent effectively that outside air from entering into in the body through the venthole.
Furthermore, an adjusting cavity is arranged in the fixing cover, the adjusting cavity is surrounded at the position limiting hole, a fixing air bag is surrounded on the side wall of the position limiting hole, and the fixing air bag is communicated with the adjusting cavity; the adjusting cavity is internally and hermetically connected with a push plate in a sliding manner, the fixing cover is provided with a screw rod in threaded connection, and the screw rod is fixedly connected with the push plate. The screw rod is rotated to push the push plate to move, so that air in the adjusting cavity is extruded into the fixed air bag, the fixed air bag can better fix the catheter, and air leakage at the position of the limiting hole can be effectively prevented.
Furthermore, an annular groove is formed in the side wall of the limiting hole, an annular air cushion ring is hermetically connected in the groove, a vent hole is formed in the fixing cover, an adjusting air bag is fixedly connected to the outer wall of the fixing cover, and the adjusting air bag is communicated with the air cushion ring through the vent hole; the fixed cover is also rotatably connected with a fixed plate used for extruding and adjusting the air bag, and the free end of the fixed plate is detachably connected with the fixed cover. The air cushion ring, the adjusting air bag, the vent hole and the fixing plate are arranged; during the use, can adjust the gasbag through the fixed plate extrusion, make the gas of adjusting in the gasbag extrude in to the air cushion circle, increase the pressure in the air cushion circle to make the air cushion circle better to the fixed effect of collecting main, ensure the seal of body.
