Abstract
Description
Technical Field
[0001] The invention relates to a device for assisting getting in and out of bed and a device for raising the body. Background Art
[0002] With the increase in the average age of the Chinese population, the elderly population is also expanding. At present, many elderly people are alone at home without the company and care of their children. In their later years, the elderly may suffer from cardiovascular and cerebrovascular diseases, such as hypertension, arteriosclerosis, hyperlipidemia, diabetes, etc. The elasticity and systolic and diastolic function of cerebral blood vessels are poor, which can easily cause cerebral ischemia. Medical experts point out that when people are sleeping soundly in the middle of the night, due to low metabolism and less activity, blood flow is relatively slow, blood pressure is relatively low, and nerves, muscles and other organs are in a state of comfort. At this time, if you get out of bed and stand up in a hazy state, it is not only easy to get hurt, but more dangerous is that the body has been lying flat for a long time with low blood pressure and slow blood flow. If you suddenly change your body position from lying flat to getting on the ground, the brain may show transient ischemia, and then the symptoms of dumping after ischemia will occur in the haze. The mild ones will feel dizzy, dizzy, and shake unsteadily, and the severe ones will fall to the ground. When the elderly get up, there is always a risk of accidents due to cerebral ischemia and confusion of the mind, and they are prone to slipping and falling and fractures when they get out of bed.
[0003] The existing assisted getting-out-of-bed method basically uses a tilted bed board to help the elderly stand up their upper body, but this assisted getting-out-of-bed method can only help the elderly's upper body, and cannot avoid the problems caused by the elderly's change of posture from prone to prone, and a series of problems caused by the change in body position have not been well solved.
[0004] There are some multifunctional nursing beds and auxiliary getting-up devices on the market now, but the functions are complicated and inconvenient for the elderly to operate, and when the elderly just wake up, their minds are not fully awake and it is difficult for them to figure it out.
[0005] Another basic method is to use the method of tilting the upper bed board to make the elderly stand up, which cannot assist the elderly to stand steadily. The entire operation process is not complete and the entire device is partially changed (only the upper bed board). The operation is relatively tough and can easily cause discomfort to the elderly. This type of auxiliary bed-raising device is mostly a medical device, which has its own professional and regulations for the height angle of standing up, and is difficult to master and widely use. It is not very suitable for ordinary elderly people. It is only limited to helping the elderly sit up, lacks the supplement of assisting the elderly to stand up, and is not enough for the elderly who are not sick to sit up. Summary of the invention
[0006] In order to solve the above problems, the present invention proposes a machine for assisting in getting in and out of bed and getting up, which can adjust the height automatically, has a wide range of applications, is simple to operate, has low cost, occupies less space, is easy to move, is suitable for elderly people to use at home, and is also suitable for nursing staff to take care of the elderly, and has great popularity and practicality.

The two-way wireless remote controls are connected between a live wire and a neutral wire through a wire, and are connected to the wireless signal of the remote control, and are used to receive the wireless signal transmitted by the remote control to control the first electric push rod or the fourth electric push rod; an AC receiver is added between the two-way wireless remote control receiver and the voltage transformer and voltage regulator module, and is used to prevent the first electric push rod from short-circuiting due to the reversal of positive and negative poles after remote control; the two remote control buttons are electrically connected to the second electric push rod and the third electric push rod through wires, respectively, and are used to control the start and stop of the second electric push rod and the third electric push rod; the first electric push rod and the fourth electric push rod are connected in parallel between the AC receiver and the two-way wireless remote control receiver through wires, and a conversion switch is added to the wires electrically connected to the first electric push rod and the fourth electric push rod, and is used to switch the electric push rod controlled by the remote control.
2. The device for assisting in getting in and out of bed and raising the body as claimed in claim 1, characterized in that: The scissor-type lifting frame includes two sets of cross-hinged frame bodies and a set of horizontally arranged lifting frames. The two sets of cross-hinged frame bodies are parallel, and the top and bottom ends of the two sets of cross-hinged frame bodies are each equipped with a set of roller connecting rod assemblies. The roller connecting rod assembly includes a connecting cross bar and a roller, wherein the first connecting cross bar is fixedly connected to the top end of the first connecting rod body, and a roller is installed at each of its two ends, and the roller is inserted into the horizontal slide groove of the lifting platform; the second connecting cross bar is fixedly connected to the bottom end of the second connecting rod body, and a roller is installed at each of its two ends, and the roller is inserted into the horizontal slide groove of the base frame; the second connecting cross bar is connected to the pushing end of the first electric push rod.
3. The device for assisting in getting in and out of bed and raising the body as claimed in claim 1, characterized in that: The switching power supply is a 24V switching power supply, which can convert a 220V AC voltage into a 24V DC voltage.
