Description

Negative pressure hydrops drainage bed

Technical Field

The invention relates to the technical field of medical equipment, in particular to a negative-pressure effusion drainage bed.

Background

The transmission routes of the novel coronavirus pneumonia are mainly direct transmission, aerosol transmission and contact transmission. Direct transmission refers to the infection caused by sneezing, coughing, speaking droplets and the close distance between the exhaled air and the direct inhalation of the patient; aerosol transmission refers to the situation that droplets are mixed in the air to form aerosol which causes infection after being inhaled; contact transmission refers to the condition that droplets are deposited on the surface of an article and contact with mucous membranes such as oral cavity, nasal cavity, eyes and the like after contacting with contaminated hands, so that infection is caused. The novel coronavirus is a virus which can cause respiratory diseases, and the clinical manifestations of the coronavirus mainly comprise cough, dry cough, dyspnea and the like, and can cause inflammation and mucus and body fluid accumulation (pneumonia) in the airways of the lung. Body position drainage is one of the important nursing measures that promote respiratory function, through with the help of external force, cooperates chest manipulation treatment simultaneously, if: the method of beating the back, shaking or spraying (medicine) and the like slightly stimulates the pharynx of the patient to cause cough, so that the patient can more conveniently discharge accumulated (phlegm) liquid out of the body from the lung and the bronchus. Usually when the patient is difficult to breathe because lung disease, chest are injured, drowned etc. lead to, the lung has long-pending (phlegm) liquid to be difficult for discharging, need under doctor's guidance, borrow corresponding position drainage, be fixed in the drainage bed with the patient, adjust the drainage bed according to different situation, make patient's head be located the low department, long-pending (phlegm) liquid position is located the eminence, presents the body position that the head is low buttockss high, realizes the drainage with the help of gravity. The drainage bed is the main facilities who is applied to the position drainage, and the drainage bed of present clinical use is mostly with the one end bed hedgehopping of sick bed, makes the sick bed slope, and patient's head is located low department, and the shank is located the eminence, and this kind of method is too crude, and poor stability, and need consume more medical care strength.

Patent "a lung lobe position drainage bed" (CN 0782922U) through the one end installation hinge at the bed board, the pad is raised in the installation of the other end, realizes that the one end angle of bed board is adjustable to reach the drainage effect, the bed board angle modulation of drainage bed is very limited in this design, and the patient needs to realize fixedly through holding the handrail.

Patent position drainage bed (CN208770203U) controls two bed boards respectively through two tilting mechanism to this shank angle and the back angle of adjusting the patient obtain suitable position, and angle of regulation is limited, and this drainage bed only relies on the action of gravity to realize the drainage effect, and does not have patient fixing device, and stability is not enough.

Patent "a novel drainage bed of multi-functional" (CN 209107868U) has set up the rail guard that prevents to fall at the lathe bed border of drainage bed, has increased certain security compared with other patents.

But the drainage effect is realized only to the help patient that has only been considered in current drainage bed to change the position, has neglected the security of drainage bed, functional and medical personnel's security and the simple operation nature. Patents (CN 0782922U) and (CN208770203U) realize the adjustment of the bed board at a limited angle, so that the patient can obtain the drainage effect to a certain extent, but the designed drainage bed has no protection device at all, and the safety of the patient cannot be guaranteed. Patent (CN 209107868U) has set up the rail guard that falls at the lathe bed edge of drainage bed, has increased certain security compared with other patents, but patient and medical personnel still direct contact, do not consider medical personnel's security.
