Description

Technical Field

[0001] The invention relates to the field of household care equipment, in particular to a household care transfer bed. Background Art

[0002] Nursing beds are generally for patients who are unable to move and have been bedridden for a long time. They need to get out of bed with the help of nursing staff every day for diet and rehabilitation training. Simply using manpower to help patients get in and out of bed is not only a great burden for nursing staff, but may also cause bumps, strains and other artificial injuries to patients due to improper force. Therefore, if conditions permit, it is recommended to purchase a nursing bed specifically for paralyzed patients. This nursing bed can better help nursing staff take care of patients in life, such as: mobile dining tables, dining table boards and sit-up functions, etc., which can help nursing staff take care of patients well and greatly reduce the burden on nursing staff. Home care mainly refers to the care of body temperature, pulse, respiration, blood pressure, pupils, etc. Changes in these vital signs reflect the improvement or deterioration of the disease. Therefore, disease observation is the focus of basic care. In addition, attention should be paid to changes in skin and mucous membranes and the color, amount, properties, and frequency of vomitus and urine. Under the general trend of the cash society, home care for the elderly is increasingly being discussed as a topic, that is, how to design a set of nursing equipment that is easy to use, easy for nursing staff to operate, reduces the difficulty of nursing staff's work, and is easy to transport. Nursing beds can be divided into two categories according to the driving mode: 1. Electric nursing beds; 2. Manual nursing beds. In addition, the multifunctional nursing bed also has a timed turning function, which can solve the problem that the elderly cannot turn over when sleeping.

[0003] At this stage, the improvements to nursing beds are mainly concentrated in the following aspects: 1. A variety of assembly posture adjustments, the nursing bed can have a variety of deformations, which is convenient for home care; 2. Improving the degree of automation, such as installing multiple motor drives to make it easy to move; 3. Improvements in appearance to enhance its commercial competitiveness; 4. Adding a guide function to guide the patient to turn over, thereby reducing the chance of bedsores; 5. Combination with various electronic monitoring instruments to achieve docking of multiple instruments.

[0004] However, at the current stage, the shortcomings of home care beds are: 1. They are often limited to home use, with large single unit size and low utilization rate, and are not suitable for use in communities or nursing homes; 2. The highly specific design makes it difficult to adapt to other occasions when patients need to be moved to other places, and nurses are required to assist in moving patients, which increases the labor intensity of nurses; 3. The equipment has a single function and there are many inconveniences during use. Summary of the invention

[0035] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] Example 1

[0037] A home care transfer bed, see Figures 1 to 8 The design includes a bed surface 1 with a deformable head and a bottom pneumatic lifting bed body 2. The bed surface 1 includes a head support 3, a trunk support and a leg support 4, wherein the head support 3 and the leg support 4 are respectively hinged and connected at both ends of the trunk support. The bottom pneumatic lifting bed body 2 includes a folding connecting rod 5 driven by a pneumatic rod. The folding connecting rod 5 includes two groups of connecting rods twisted in a scissor shape. One side of the connecting rod group is hinged and connected to the bottom support via a rotating circle, and the other side is slidably sleeved on the bottom support 6 and connected to the bottom support via a rotating moving pair. Rollers 7 are provided at the four corners of the bottom support 6. A limiting mechanism for limiting the opening height of the folding connecting rod 5 is provided on the lifting bed body, and the lifting bed body is eccentrically located below the head support 3 and the trunk support. When in use, each pneumatic rod is controlled to cause the bed surface to deform in the direction required by the patient or medical staff. The use of pneumatic rods can refer to the pneumatic storage bed in the field of building materials. When the bed surface is flat and the foldable connecting rod is at the extreme position close to horizontal, the entire device is at the lowest height and can be directly lifted up and docked with the ambulance for transportation. Furthermore, by utilizing the characteristics of the gas pressure rod, a slight pressure on the foldable connection can cause it to deform and complete the transformation from use to transportation. For patients who are commonly bedridden, this undoubtedly shortens the rescue time.

[0038] A urine bag hanging rod 9 is provided on the back of the trunk support, and an arc-shaped limiting groove 10 is provided on the hanging rod. In this design, the urine bag is reasonably lower than the buttocks and higher than the ground, which is convenient for urine drainage and collection and sorting by medical staff, while protecting the urine bag itself and extending its service life. At the same time, it can also move with the nursing bed during home care.

[0039] A stomach tube placement groove 8 is also provided on the back of the trunk support, and a contact sensor is provided in the stomach tube placement groove 8. A first motor 11 that drives the hinged connection main shaft of the trunk and head support 3 to rotate is connected to the output end of the controller, and the input end of the controller is connected to the contact sensor. The purpose of this design is that when the stomach tube syringe is taken out of the stomach tube placement groove, the bed surface can be electrically controlled to tilt to a suitable angle to prevent esophageal reflux caused by unprofessional caregivers. In the applicant's long-term front-line work, it is found that for patients who need external assistance to feed through a stomach tube, the principle of ensuring the upper body tilt during feeding and 15 minutes after feeding is often forgotten. This design uses an electronic control device to directly drive the tilt of the bed. In the specific use process, a time relay circuit can also be introduced to control the deformation time of the bed to further ensure the safety of the patient.

[0040] A ventilation interlayer is provided on the bed surface 1, and an air source inlet is provided on the ventilation interlayer, wherein the air source issuing device is fixed on the back of the trunk support. Ensuring ventilation of the back can reduce the risk of bedsores in patients to a certain extent.

[0041] There are widened boards on both sides of the bed, making it easier for patients of all sizes to use.

[0042] In this embodiment, a controller connected with a circuit is included, the input end of the controller is connected to each rotating motor, and a control board is arranged on the lifting bed, and the control board is connected to the input end of the controller.

[0043] An armrest 13 is also installed on the side of the lifting bed, and a storage element 14 is provided on the armrest 13. This design is convenient for various connection pipes and placement of some electronic measurement and monitoring components on the one hand, and is used to install a controller on the other hand, which is convenient for patients to control themselves. In the specific implementation, the armrest and the bed surface can be fixed with pins, and the length of the pins is designed to be no greater than the width of the widening plate. At the same time, the widening plate and the bed surface are also fixed by positioning with pins.

[0044] The limiting mechanism includes a limiting rope of standard size, one end of which is fixed to the side of the bottom support 6, and the other end is wound around the limiting column 16 on the side of the lifting bed. The limiting rope is used together with the equipment and includes multiple different sizes. During use, a set of three limiting ropes of the same size are selected for limiting, limiting the travel range of the folding connecting rod to return, thereby achieving the effect of adjusting the reset height. The height adjustment is to adapt to the transfer between beds of different sizes and reduce the workload of medical staff during transfer. The two ends of the limiting rope can be fixed by hook or by binding.

[0045] Embodiment 2, the principle of this embodiment is the same as that of embodiment 1, and the specific difference is that: the limit mechanism is replaced by a limit block installed at the bottom of the upper side of the lifting bed, and the limit rod 17 is rod-shaped, and both ends are clamped on both sides of the bottom support 6. During the return process of the foldable connecting rod, the limit block limits the return stroke range, thereby achieving the effect of adjusting the reset height.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
