Description

Device for preventing getting up and falling down

Technical Field

The invention relates to the technical field of medical instruments, in particular to a device for preventing getting-up and falling down.

Background

At present, the falling incidence rate of old patients is high, and especially, old high-risk patients have research and research display: out of 360 patients with clear consciousness (except for bedridden patients) who are more than 2 weeks old and 65 years old, 134 patients have fallen, and the incidence rate of the falls is 37.22%. The fall causes injuries and losses of different degrees to patients, families and even hospitals, including fracture, cerebral hemorrhage, soft tissue contusion and laceration, etc., and brings expenses of additional medical expenses, even causes contradiction, dispute and compensation between doctors and patients.

Although each hospital at present brings the elderly patients into one of key monitoring contents in daily nursing work by falling, needs to make detailed repeated notification and health education, requires family members to accompany for 24 hours, posts high-risk anti-falling warning signs, improves the environments such as sickrooms and toilet floors, and adds nursing bed fences, the elderly patients have poor self-compliance and the family members or nursing staff cannot leave the patients 24 hours later, and especially the elderly patients fall and/or fall down at night (such as 0-4 am). It is therefore important how to find the first time that an elderly patient has a wake-up action.

To solve the above problems, the present chinese patent with application number 201521088497.3 discloses a fall-down prevention device, which comprises a vest body, an air bag is arranged on the vest body, and the fall-down prevention device further comprises: the pressure signal judging device is respectively connected with the pressure detecting device and the alarming device in a signal mode. When a user gets up, the alarm device is triggered through pressure change to remind nursing families or nursing workers, so that the condition of the patient can be known at the first time, and the falling accident can be prevented to the greatest extent.

Chinese patent that application number is 201720813368.9 simultaneously in addition discloses an old person early warning device that gets up, and it includes the box, the box includes left side board and right side board, be equipped with the opening on the board of right side, the opening part is equipped with the gasbag, the gasbag includes half on the left side and half on the right side, half a left side of gasbag is located the box, half a right side of gasbag is located outside the box, the inside of box is located the top that half a left side of gasbag has been irritated liquid, be equipped with the sensor that is used for monitoring the liquid level on the inner wall of half a left side board, the sensor is located the top of gasbag, the sensor is connected with alarm controller, alarm controller is connected with the alarm. Its early warning device that provides can monitor old person's getting up, and the early warning starts when old person gets up, and the accompanying person in time helps or intervenes to the bedside through the early warning, reaches the purpose of preventing weighing down the bed, tumbles, considers its compliance of using simultaneously, sets the device to functional structure between the neck that accords with old person to increase the shape of comfort level.

Although the above two publications are effective in solving the above problems, the above two publications still have the following problems in practical use:

1) an anti-falling device with application number 201521088497.3, which will give an alarm if a patient turns to a side sleeping posture during sleeping during use, thereby causing a phenomenon of false alarm and causing unnecessary trouble to caregivers or caregivers;

2) the application number is 201720813368.9's an old person early warning device that gets up, it is in the use, if the patient stands up to sit on the sick bed or when patient's head breaks away from the gasbag, it will report to the police, therefore it can not accurately judge whether the patient really will get up, leads to often producing the phenomenon of wrong report police from this, brings unnecessary trouble for accompanying person.

3) Above-mentioned two patents, in case can last the warning after the warning, other patients of serious interference need the outage just can eliminate the chimes of doom, use relatively troublesome.

Therefore, a device for preventing getting up and falling down is provided.

The housing 3 of examples 1 to 4 was put in a humid environment with a certain concentration of bacteria for 36 hours in a laboratory and then taken out to a microscope, and the following observations were made:

examples	Observation results
		Example 1	The surface of the shell 3 is distributed with a plurality of bacteria
Example 2	The surface of the shell 3 is distributed with a small amount of bacteria
		Example 3	The surface of the shell 3 is distributed with a small amount of bacteria
Example 4	The surface of the shell 3 is distributed with a small amount of bacteria
