Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an intelligent medical nursing bed. Background Art

[0002] Patients with poor mobility due to injuries or surgeries in hospitals face many inconveniences during their hospitalization, especially in bed. Patients who have been bedridden for a long time and have difficulty turning over will suffer from physical health if they lie in bed for a long time. Therefore, medical staff are often required to assist in turning over. However, this kind of assisted turning over work not only brings huge workload to medical staff, but also easily causes secondary injuries to patients if they turn over improperly.

[0003] Existing nursing beds often have the function of taking care of patients' daily lives, but very few of them can help patients turn over.

[0004] The patent application with publication number CN201310064256.4 and publication date November 27, 2013 discloses an electrically controlled turning bed, which uses a conveyor belt and multiple rollers to turn the patient over. This solution requires a very large space to perform the corresponding turning, and the operation process is complicated.

[0005] The patent application with publication number CN 104352315 A and publication date February 18, 2015 discloses a patient care bed with an auxiliary turning function and an auxiliary turning method thereof. The solution turns the patient over by rolling up a cloth. However, due to the flexibility of the turning cloth itself, the turning method is extremely unstable and the patient may easily fall off the bed during the turning process. Summary of the invention

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0036] The present invention provides an intelligent medical nursing bed. Figure 1 and Figure 2 As shown, it includes an outer bed body 100, an inner bed body 200 and a support frame 300; the outer bed body 100 and the inner bed body 200 are semi-cylindrical, the inner bed body 200 is embedded in the outer bed body 100 and is connected to the servo motor 400 shaft arranged on the front and rear sides of the outer bed body 100, and the support frame 300 is arranged under the outer bed body 100.

[0037] Specifically, when turning over is required, the servo motor 400 is controlled to start. The servo motors 400 are set on both sides of the bed, and two can be set specifically, which can smoothly control the rotation of the inner bed 200. The corresponding rotation speed and rotation angle can be achieved according to the actual situation and the existing technology. When turning over to a certain extent, the patient or the medical staff only need to provide simple support and protection to achieve turning over; when turning over is completed, the servo motor 400 controls the inner bed 200 to rotate and return to the initial position. Among them, the control button of the servo motor 400 can be set on the outside of the bed to facilitate the control of the medical staff, or it can be set on the inside of the bed to facilitate the patient's self-control.

[0038] The intelligent medical nursing maternity bed provided by the present invention can realize or assist the patient's turning over by directly controlling the rotation of the bed body. The semi-cylindrical bed body is designed to make the patient more stable when turning over, greatly increasing the safety of the patient when turning over and reducing the work efficiency of medical staff. The intelligent medical nursing maternity bed has important practical application value in the field of medical care.

[0039] On the basis of the above technical solution, further, Figure 2 As shown, a sub-bed 500 is arranged on the side of the outer bed 100, and the outer bed 100 and the inner bed 200 are provided with notches at the bed edges corresponding to the sub-bed 500, and the bed edge height of the sub-bed 500 near the notch is lower than the height of the sub-bed 500. In this scheme, in order to enable the mother to take better care of the baby and prevent the baby from affecting the mother's health, the design of a mother-and-child bed is adopted, and a baby bed is arranged on the side of the main bed, and the setting position is approximately at the breastfeeding position, and the bed edge height of the sub-bed 500 near the notch is lower than the height of the sub-bed 500, which can prevent the baby from falling into the main bed on the one hand, and on the other hand, it is convenient for the mother to take care of the baby in a state where she does not fully stand up, and it is also more convenient to place the baby in the sub-bed after breastfeeding.

[0040] On the basis of the above technical solution, further, the inner wall of the inner bed body 200 is a smooth inner wall, and the inner bed body 200 is provided with a first mattress 210 and a second mattress 220 which are connected to each other and attached to the inner wall of the inner bed body 200, and the first mattress 210 is arranged at the bottom of the inner wall of the inner bed body 200;

[0041] The inner wall of the inner bed body 200 is provided with a one-way hook groove 230. After the inner bed body 200 rotates, the one-way hook groove 230 is placed on the bottom side of the first mattress 210 and / or the second mattress 220. During the rotation of the inner bed body 200, the one-way hook groove 230 causes the first mattress 210 and the second mattress 220 to be displaced, and the second mattress 220 is placed at the original position of the first mattress 210.

[0042] In the above preferred embodiment, on the basis of the design that enables the patient to turn over, a solution is also provided that enables the mattress to be easily replaced. The inner wall of the inner bed body 200 can be made of polished stainless steel to ensure smoothness; the structure of the one-way hook groove 230 is as follows: Figure 1 As shown in FIG. 2 , when the inner bed body 200 rotates (as shown in FIG. Figure 3 As shown), the smooth surface of the hook groove contacts the mattress and does not affect the displacement of the mattress. Due to the pressure of the human body and the smooth inner wall, the position of the mattress does not change significantly. When the servo motor 400 controls the inner bed body 200 to rotate (as shown in FIG. Figure 4As shown), the hook surface of the barb groove forms resistance to the mattress, thereby dragging the mattress; wherein, the power of the servo motor 400 in controlling the rotation of the inner bed body 200 can be controlled according to the patient's weight. For example, a patient with a large body weight can increase the output power by controlling the servo motor 400, and a patient with a small body weight can reduce the output power by the servo motor 400. The relationship between the above-mentioned weight and power can be obtained by technical personnel in this field through specific experimental tests.

[0043] In addition, the first mattress 210 and the second mattress 220 are connected in a manner as follows: Figure 5 As shown, the side edges of the first mattress 210 and the second mattress 220 are fixed by means of buckles; when the first mattress 210 is pulled away from the patient's body (the patient can also assist in this process to facilitate the mattress pulling out), the second mattress 220 is dragged to the original position of the first mattress 210, that is, under the patient's body, and the mattress replacement can be completed; after replacement, the first mattress 210 can be disassembled and washed, and at the same time, the third mattress (similar to the first and second mattresses in structure) is connected to the second mattress 220 by buckles to prepare for the next replacement.

[0044] Specifically, the number of the one-way barb grooves 230 in the above solution can be set according to specific needs.

[0045] Preferably, a one-way paddle 221 is provided on the side of the second mattress 220, and the one-way paddle 221 is fixedly connected to the outer bed body 100. When the inner bed body 200 rotates, the resistance of the one-way paddle 221 to the second mattress 220 is smaller than the resistance of the one-way paddle 221 to the second mattress 220 when the inner bed body 200 rotates. Figure 6 As shown, the blocking end of the one-way paddle 221 is set downward. Since mattresses generally have a certain elasticity, when the inner bed body 200 rotates, the one-way paddle 221 can block the second mattress 220 from rotating upward synchronously. When the inner bed body 200 rotates, the one-way paddle 221 will not block the second mattress 220, and allows the second mattress 220 to be dragged to the original position of the first mattress 210, that is, under the patient's body.

[0046] Preferably, a humidity sensor 240 is provided at the contact position between the inner bed body 200 and the first mattress 210, and the humidity sensor 240 transmits a signal to a single-chip microcomputer, and the single-chip microcomputer controls the rotation of the servo motor 400 according to instructions; specifically, the single-chip microcomputer can adopt at least one of AX1001, STC, AT91M, and MCS-51.

[0047] Taking into account the patient's physical condition, when excrement or liquid contaminants flow out and penetrate into the mattress, the humidity sensor 240 can transmit the detected data to the single-chip microcomputer, and set a certain threshold for the single-chip microcomputer. When the humidity exceeds a certain threshold, the single-chip microcomputer controls the servo motor 400 to rotate, thereby completing the automatic replacement of the mattress. In addition, an alarm device can also be set. When the humidity exceeds the threshold, the alarm information can also be transmitted to medical staff, which is convenient for medical staff to deal with it in time, prevent patients from being infected again under long-term contaminants, and improve the safety of patient medical care.

[0048] On the basis of the above technical solution, further, the bottom side of the inner bed body 200 is provided with an adsorption through hole 250, and the adsorption through hole 250 penetrates the inner bed body 200; an adsorption chamber 260 is provided between the outer bed body 100 and the inner bed body 200, and the adsorption chamber 260 corresponds to the position of the adsorption through hole 250, and is connected to the adsorption pump 130 provided in the support frame 300; further, the adsorption chamber 260 is made of silicone rubber. When the mattress is contaminated by liquid pollutants, adsorption can assist the mattress to penetrate quickly, and combined with the design of the humidity sensor, the efficiency of detection can be guaranteed, and the contaminated mattress can be quickly and conveniently treated to prevent the patient from being in the environment of contaminated liquid for a long time; the adsorption chamber 260 can also be connected to the collection tank to complete the collection of contaminated liquid.

[0049] On the basis of the above technical solution, further, the first mattress 210 and the second mattress 220 can be made of polyurethane, activated carbon powder, titanium dioxide, and nano zinc powder by mixing them in a ratio of 10:3~5:1~2:0.01~0.03 and then foaming them; polyurethane is often used to prepare memory sponge, but general memory sponge has a large static friction with the interface. When the inner bed body 200 rotates, it is easy to drive the mattress to rotate synchronously, which will reduce the success rate of correct mattress replacement; by adding activated carbon powder and titanium dioxide for modification, the friction with the inner wall of the inner bed body 200 can be reduced while ensuring the elasticity and adsorption force of the mattress, and nano zinc powder can improve the bactericidal ability of the mattress; the specific preparation method can refer to the existing foaming process. In addition, the proportion of titanium dioxide used in the bottom material of the mattress can be increased. For example, the mattress can be layered, with the upper material made of polyurethane, activated carbon powder, and titanium dioxide at a ratio of 10:3:1, and the lower material made of polyurethane, activated carbon powder, and titanium dioxide at a ratio of 10:5:2. This can not only ensure the adsorption capacity of the mattress after contact with liquid, but also reduce the friction between the mattress and the inner bed body 200, preventing the mattress from moving synchronously when the inner bed body 200 rotates.

[0050] On the basis of the above technical solution, further, Figure 1As shown, the inner wall of the outer bed 100 is fixedly provided with a ball mounting groove 110, and the ball 120 is arranged in the ball mounting groove 110, and the ball 120 is in contact with the outer wall of the inner bed 200. The inner and outer beds connected by the ball 120 can support the inner bed 200 on the one hand, and reduce the friction between the inner and outer beds on the other hand, while avoiding the burden caused by directly using a motor to drive the inner bed 200 to rotate, reducing energy waste, saving energy, reducing electrode loss, and increasing service life. Among them, the number of ball mounting grooves 110 and balls 120 used can be selected accordingly according to actual needs.

[0051] Preferably, the support frame 300 includes a support rod 310 and a base 320, the upper and lower ends of the support rod 310 are respectively connected to the outer bed body 100 and the base 320, the support rod 310 is a retractable rod, and the height of the bed can be adjusted accordingly; the base 320 is provided with a retractable universal wheel 321. When the intelligent medical nursing mother-and-child bed needs to be moved, the retractable universal wheel 321 can be opened to assist the movement of the bed; when it is not necessary to move, the retractable universal wheel 321 can be retracted to fix the bed.

[0052] Although the terms such as outer bed body, inner bed body, support frame, servo motor, first mattress, second mattress, one-way hook groove, one-way pick, humidity sensor, adsorption through hole, ball mounting groove, ball, adsorption pump, support rod, base, telescopic universal wheel, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
