Description

Technical Field

[0001] The present application belongs to the technical field of medical supplies, and in particular relates to a pump-type flushing and waste liquid collection device for sputum care. Background Art

[0002] At present, in the field of nursing care for critically ill patients in hospitals, sputum care is often required for patients. During the nursing process, the negative pressure when suctioning patients is generally between 0.02-0.04MPa. In addition to being used for suction care, the negative pressure in hospitals is also used for other waste liquid collection, especially during surgery when a large amount of waste liquid is collected. These application scenarios often require relatively large negative pressure. Therefore, the negative pressure gas source in the hospital is often higher than 0.04MPa, and some even have a pressure of 0.08MPa. Therefore, during suction care, the negative pressure is too high, and patients with poor tolerance often have a strong emergency response. At present, most of the negative pressure source meters in hospitals control the switch of the gas source through a knob switch, and it is difficult to control the output negative pressure gas source. Pressure, so it is necessary to improve the current usage method. At the same time, when medical staff use suction tubes for suction care, the control switches are all open switches, and are all on the end handle of the suction tube. In this way, the sputum produced by the patient will inevitably pass through the open switch. Although the medical staff press the switch with gloves, it is an open operation after all, which will inevitably cause sputum splashing, affecting the working environment of the medical staff and even causing secondary pollution. For patients with thicker respiratory tract sputum, general suction care is difficult to clean the sputum. In order to solve this problem, medical staff will let the patient inhale atomized drugs to promote expectoration, or use a sputum removal machine to remove sputum, which increases the cost of atomization or the cost of the sputum removal machine, and also increases the difficulty of care;

[0003] Therefore, in view of the fact that the current negative pressure gas source pressure is difficult to control and adjust, and that suction care is difficult for some patients with thick sputum, it is necessary to develop a device for suction care that is safe, environmentally friendly, economical, and easy to operate.

At this time, part of the bistable dome spring a44 or the bistable dome spring b51 is transformed into a convex state. At this time, the inner wall of the bistable dome spring a44 is separated from the surface sealing effect between the inner pit surface a42, and the air flow enters the box body 39 through the secondary microporous community a45 and the main microporous community a43, or the inner wall of the bistable dome spring b51 is separated from the inner wall of the bistable dome spring b51. The surface sealing effect between the separation and the inner pit surface b49 causes the air flow to enter the box body 39 through the secondary microporous community b52 and the main microporous community b50, and the negative pressure value of the terminal suction hole 21 is reduced. More bistable dome shrapnel a44 and bistable dome shrapnel b51 are gradually pulled until the terminal negative pressure value reaches the standard. The left hand operates the suction tube 4 to be placed on the patient's sputum position. The sputum enters the inner cavity of the suction tube 4 along the multiple suction holes 21 under the negative pressure suction force, enters the adapter 7 along the suction tube 4, and falls into the waste liquid collection bag 11 through the adapter 7; if the patient's part needs to be flushed, the right hand presses the pump pressure head 12 at this time, and the flushing liquid pot The flushing liquid in 13 will flow along the flushing tube 14, the oblique tube 20 and the flushing extension tube 17, and finally be flushed through the sputum suction hole 21; if the sputum is too thick and the attraction is insufficient, at this time, just press the pulling handle a46 or the pulling handle b53 pulled open in the above steps, and the part of the bistable dome shrapnel a44 will be transformed into a concave state again, and the inner wall of the bistable dome shrapnel a44 will be close to the outer wall of the inner pit surface a42, and the part of the bistable dome shrapnel b51 will be transformed into a concave state again, and the inner wall of the bistable dome shrapnel b51 will be close to the outer wall of the inner pit surface b49, returning to the surface sealing state, and the negative pressure value of the terminal sputum suction hole 21 will be improved.
