Description
Technical Field
The utility model relates to a two-way regulating switch of thoracic drainage tube, more specifically say specifically, especially relate to a two-way regulating switch of thoracic drainage tube that can conveniently close the drainage tube when changing the water-sealed bottle, detecting drainage volume or patient get on or off the bed.
Background
The thoracic surgery patient needs to place a closed thoracic drainage tube in a conventional way after operation, one end of the thoracic drainage tube is placed in a pleural cavity, and the other end of the thoracic drainage tube is connected with a closed water-sealed bottle for drainage and promotion of wound healing. The nurse needs regularly to detect the drainage volume and change the normal saline in the water-sealed bottle, changes the normal saline in-process, in order to prevent that gas from getting into the pleural cavity, need utilize the vascular pincers to press from both sides the pipeline closed. However, the clamping of the thoracic drainage tube by the vascular clamp has the following disadvantages:
(1) The drainage tube is frequently clamped and closed by the vascular clamp, the drainage tube is easy to break, and complications such as pneumothorax and the like can be caused after gas enters the pleural cavity from the broken part. (2) When the patient is inserted with the drainage tube, family members help the patient to get on or off the bed, also need to utilize vascular pincers to clip the drainage tube closed, if vascular pincers use the misoperation, can cause the drainage liquid to flow backward, cause adverse effect to patient's recovery and treatment. (3) Every patient need borrow a vascular pincers to the nurse before the art, and vascular pincers need the handing-over in the operation transportation, have the risk of losing. (4) The number of the vascular clamps needs to be checked, borrowed, returned and disinfected regularly by each nurse, and the labor intensity of the nurses is increased. (5) The vascular clamp is easy to damage in the using process, and the operating cost of a department is increased. (6) The vascular clamp is stored in a patient for a long time during use, and has potential safety hazards.
If an operating switch can be arranged on the thoracic drainage tube, when medical personnel detect the drainage quantity, change the normal saline in the water-sealed bottle or a patient goes up and down to go to the toilet, the drainage tube is closed by using the operating switch; when a patient lies in bed, the drainage tube is opened, so that the problem caused by clamping and closing the drainage tube by using vascular forceps can be solved. Because viscous substances such as blood clots and the like possibly exist in the drainage liquid in the thoracic cavity, the diameter of the drainage tube cannot be reduced in order to ensure normal drainage of the thoracic cavity, and a switch valve on the urethral catheterization bag cannot be adopted, and the normal outflow of the drainage liquid in the thoracic cavity can be influenced because a cross rod is arranged in the middle of the switch valve on the urethral catheterization bag.
