Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a postoperative positioning and nursing device for gastrointestinal surgery. Background Technology

[0002] Postural adjustment after gastrointestinal surgery is a crucial aspect of postoperative care, directly affecting the patient's recovery speed and the incidence of complications.

[0003] To prevent respiratory complications, the main ways to adjust body position are as follows: patients who have not yet regained consciousness from general anesthesia should lie flat without a pillow and turn their head to one side to prevent aspiration of vomit, which could lead to suffocation or aspiration pneumonia; a semi-recumbent position (upper body elevated 30-45°) can reduce pressure on the diaphragm, promote lung expansion, and reduce the risk of atelectasis.

[0004] However, current postoperative positioning adjustments for gastrointestinal surgeries mainly rely on medical staff manually assisting patients to turn over or patients independently adjusting their posture by holding onto handrails, which has significant drawbacks:

[0005] 1. Manual turning requires the coordination of multiple medical staff, which is time-consuming and labor-intensive (the average time for a single adjustment is ≥3 minutes). Furthermore, the position angle depends on experience and judgment, which can easily lead to uneven support, resulting in ineffective relief of pressure on the diaphragm and increasing the risk of swelling.

[0006] 2. Traditional mattresses cannot deform synchronously with body position, which can easily lead to local high pressure areas in the patient's lower back, increasing shear force and inducing pressure sores.

[0007] Therefore, it is necessary to design a postoperative positioning and nursing device for gastrointestinal surgery to solve the above-mentioned technical problems. Utility Model Content

[0008] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a postoperative positioning and nursing device for gastrointestinal surgery.

[0009] The technical solution is as follows: A postoperative positioning and nursing device for gastrointestinal surgery includes a bed frame, which consists of legs and a bed board. Guide grooves are symmetrically formed on both sides of the bed board. Motors are installed on both sides of the bottom of the bed board. First helical rods are rotatably connected to the middle of both sides of the bottom of the bed board. The output shaft of the motor is connected to the corresponding first helical rod. Guide rods are symmetrically arranged on both sides of the bottom of the bed board. A connecting rod is slidably connected between two guide rods on the same side. The middle of the two connecting rods is threadedly connected to the corresponding first helical rod. Sliding blocks are arranged on both sides of the top of the connecting rods. Lifting rods are hinged to the top of the sliding blocks. The upper part of each lifting rod slides into the corresponding guide groove. The bed board is connected to a three-section folding pad at the top. A top plate is connected between the tops of the two lifting rods on the same side. The top plate is embedded in the bottom of the folding pad. The folding pad is covered with a foldable foam mattress. A controller for operating various electrical components is installed on the outside of the bed board. Guardrails are installed at the top of the head and foot of the bed board. Air jet pipes are connected inside the two top plates. There are horizontal jet outlets at both ends of the air jet pipes. The two jet outlets are connected to the guardrails at the head and foot of the bed, respectively. An air pump is installed outside the pipes of the jet outlets. The two ends of the jet outlets extend to the head and foot of the bed, and filter caps are fitted at both ends of the jet outlets.

[0010] Furthermore, it is particularly preferred that the device also includes a reinforcing base plate, wherein the folded portion in the middle of the folding pad is the reinforcing base plate, the folding pads on both sides are rotatably connected to the reinforcing base plate, and the reinforcing base plate is fixedly connected to the bed board of the bed frame.

[0011] Furthermore, it is particularly preferred that the nozzle also includes a filter screen, with the ejector portions at both ends of the jet pipe arranged opposite each other, and the ejector portions of the jet pipe having multiple symmetrical nozzles, each nozzle having a filter screen installed in its outlet.

[0012] Furthermore, it is particularly preferred that the device also includes a first solenoid valve, which is installed on the outside of the jet pipe near one of the air pumps.

[0013] In addition, it is particularly preferred that the device also includes a diversion tube, a second solenoid valve and an airbag. The bottom of the jet pipe is connected to a downwardly bent diversion tube. One end of the diversion tube passes through the bed board, the folding pad and the inside of the foam mattress of the bed frame. A second solenoid valve is installed on the outside of the diversion tube. An airbag is connected to the top of the foam mattress. The airbag and the end of the diversion tube passing through the foam mattress are connected.

[0014] In addition, it is particularly preferred that the device also includes a pressure relief regulator and a skin-friendly cover, with the pressure relief regulator installed at the middle section of the outside of the shunt tube and the airbag covered with a skin-friendly cover.

[0015] In addition, it is particularly preferred that the bed frame also includes a second helical rod, a support cylinder, and a handwheel. The bottom of each leg of the bed frame is threaded with a second helical rod, the support cylinder is threaded onto the outside of the second helical rod, and a circular handwheel is provided on the outside of the support cylinder.

[0016] In addition, it is particularly preferred that an anti-slip pad is included, with the bottom of the support cylinder having an anti-slip pad glued on.

[0017] The beneficial effects of this utility model are as follows: 1. This utility model uses a dual-motor driven first spiral rod to lift the folding pad, achieving precise body position adjustment, evenly supporting the lower back, and reducing diaphragmatic pressure; the air jet pipe blows clean airflow onto the bed surface after being filtered by the filter cover, forming a dynamic air layer to reduce skin friction and moisture, and prevent pressure sores; the foldable sponge mattress adapts to the curve of the body, reduces shear force, and, in conjunction with the controller, switches body position modes to quickly complete the adjustment, significantly optimizing the quality of postoperative care.

[0018] 2. This utility model uses a reinforced base plate in the middle of the folding pad to fix it to the bed frame, which enhances the overall rigidity and prevents the folding pad from shifting or collapsing when the top plate is lifted, thus ensuring the stability and safety of body position adjustment; the multiple symmetrical nozzles of the spray section have built-in filters to intercept dust and microorganisms, and the clean airflow blows directly onto the patient's body, reducing the postoperative infection rate, which is especially suitable for immunosuppressed patients.

[0019] 3. This utility model controls the on / off state and flow rate of the jet pipe through the first solenoid valve to achieve continuous air supply or intermittent pulse mode, adapting to the comfort needs of different patients; the diversion tube directs part of the airflow into the airbag, and the airbag disperses the pressure to the bony prominence area through the skin-friendly cover. Combined with the real-time monitoring of the pressure relief regulator, it automatically vents when there is overpressure to prevent pressure sores and ischemic injuries.

[0020] 4. This utility model adjusts the height of the support cylinder by rotating the handwheel to drive the second screw rod, so as to realize independent control of each support leg to adapt to uneven ground; the anti-slip pad at the bottom of the support cylinder can keep the bed stable in wet and slippery environments and prevent the risk of displacement.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0031] Example: A postoperative positioning and nursing device for gastrointestinal surgery, such as... Figures 1-8As shown, the device includes a bed frame 1, which serves as the supporting structure and provides a lying platform for the patient. The bed frame 1 consists of legs and a bed board. Guide grooves are symmetrically formed on both sides of the bed board. Motors 2 are installed on both sides of the bottom of the bed board. First spiral rods 3 are rotatably connected to the middle of the bottom of the bed board. The output shaft of the motor 2 is connected to the corresponding first spiral rod 3. Guide rods 5 are symmetrically arranged on both sides of the bottom of the bed board. A connecting rod 4 is slidably connected between two guide rods 5 on the same side. The motor 2 drives the first spiral rods 3 to rotate, and through threaded transmission, pushes the connecting rods 4 to translate, realizing the power output for body position adjustment. The middle of the two connecting rods 4 is threadedly connected to the corresponding first spiral rods 3. Slider blocks 6 are set on both sides of the top of the connecting rods 4. Lifting rods 7 are hinged to the top of the sliders 6. The upper part of each lifting rod 7 is slidably connected to the corresponding guide groove. A three-section folding pad 8 is connected to the top of the bed board. A top plate 9 is connected between the tops of two lifting rods 7 on the same side. The top plate 9 is embedded in the bottom of the folding pad 8. The lifting rods 7 are connected through a hinged structure. The translational motion of slider 6 is converted into the lifting motion of top plate 9, driving the deformation of folding pad 8. Folding pad 8 is covered with a foldable foam mattress 10. The foam mattress 10 is made of memory foam, conforms to the curve of the patient's back, and bends synchronously with folding pad 8 to distribute pressure and reduce shear force. A controller 11 is installed on the outside of the bed board to control the operation of various electrical components. The controller 11 is connected to various electrical components through cables. The head and foot of the bed board are equipped with guardrails 12 to prevent the patient from falling and to provide a gripping fulcrum to assist in adjusting posture. The two top plates 9 are connected to the inside of the air jet pipe 13. The air jet pipe 13 has a horizontal jet outlet at both ends to deliver filtered clean air to the jet outlet at the head and foot of the bed, forming an airflow layer to isolate the skin from the foam mattress 10 and reduce friction and moisture. The two jet outlets are respectively connected to the inside of the guardrails 12 at the head and foot of the bed. An air pump 14 is installed outside the pipe of the jet outlet. The two ends of the jet outlet extend to the head and foot of the bed, and the two ends of the jet outlet are covered with filter caps 16.

[0032] like Figure 2 As shown, it also includes a reinforcing base plate 701. The folded part in the middle of the folding pad 8 is the reinforcing base plate 701. The folding pads 8 on both sides are rotatably connected to the reinforcing base plate 701. The reinforcing base plate 701 is fixedly connected to the bed board of the bed frame 1, which can enhance the overall rigidity and prevent the folding pad 8 from shifting laterally or collapsing when the top plate 9 is lifted, thus ensuring the stability and safety of body position adjustment.

[0033] like Figure 4 and Figure 5 As shown, it also includes a filter screen 15. The ejection portions at both ends of the jet pipe 13 are arranged opposite each other. The ejection portion of the jet pipe 13 is provided with multiple symmetrical nozzles. Each nozzle has a filter screen 15 installed in its air outlet to intercept dust and pathogens in the airflow and ensure that the airflow blown toward the patient is clean.

[0034] like Figure 6 and Figure 7As shown, it also includes a first solenoid valve 17. The first solenoid valve 17 is installed on the outside of the jet pipe 13 near one of the air pumps 14. It is used to switch the airflow mode of the jet pipe 13, such as continuous air supply or intermittent pulse, so as to adapt to different skin care needs.

[0035] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a diversion tube 18, a second solenoid valve 19, and an airbag 22. The bottom of the jet pipe 13 is connected to the downward-bent diversion tube 18. One end of the diversion tube 18 passes through the bed board of the bed frame 1, the folding pad 8, and the interior of the foam mattress 10. The second solenoid valve 19 is installed on the outside of the diversion tube 18. The second solenoid valve 19 is used to control the inflation flow of the airbag 22. The first solenoid valve 17 and the second solenoid valve 19 are both controlled to open and close by electrical signals. The top of the foam mattress 10 is connected to the airbag 22. The airbag 22 and the diversion tube 18 are connected at the end of the foam mattress 10. The airflow of the diversion part of the air pump 14 is injected into the airbag 22 to support the bony prominence area and prevent pressure sores.

[0036] like Figure 6 and Figure 7 As shown, it also includes a pressure relief regulator 20 and a skin-friendly cover 21. The pressure relief regulator 20 is installed at the middle section of the outside of the diversion tube 18. The pressure relief regulator 20 monitors the pressure inside the airbag 22 in real time and automatically releases air when there is overpressure to avoid excessive local pressure. The airbag 22 is covered with a skin-friendly cover 21, which is made of medical-grade pure cotton fabric to ensure that it is non-allergenic when in contact with the skin. It is also flexible and breathable. After the airbag 22 is inflated, it expands evenly, and the skin-friendly cover 21 distributes the pressure to a larger area, reducing the risk of local pressure sores.

[0037] like Figure 1 and Figure 8 As shown, it also includes a second spiral rod 23, a support cylinder 24, and a handwheel 25. The bottom of each leg of the bed frame 1 is threaded with the second spiral rod 23. The support cylinder 24 is threaded onto the outside of the second spiral rod 23. A circular handwheel 25 is provided on the outside of the support cylinder 24. By rotating the handwheel 25, the support cylinder 24 is driven to rise and fall, and the height of the legs is adjusted to adapt to uneven ground.

[0038] like Figure 1 and Figure 8 As shown, it also includes an anti-slip pad 26. The bottom of the support cylinder 24 is glued with an anti-slip pad 26. The anti-slip pad 26 is made of silicone material, which can increase the friction between the legs and the ground, prevent the bed frame 1 from sliding, and ensure stability.

[0039] Before use, medical staff start the device through controller 11. The system performs a self-check to confirm that the motor 2, air pump 14, first solenoid valve 17, second solenoid valve 19 and pressure relief regulator 20 are connected normally. The patient lies flat on the sponge mattress 10 with his head behind the headboard guardrail 12. By rotating the handwheel 25 at the bottom of the bed frame 1 leg, the second screw rod 23 is driven to raise and lower the support cylinder 24, adjusting the overall height of the bed. The anti-slip pad 26 at the bottom of the support cylinder 24 is in close contact with the ground through silicone material to prevent the bed from sliding. Each leg supports independent adjustment to adapt to uneven ground and ensure the bed is level and stable.

[0040] At the same time, the controller 11 sends instructions to the two motors 2. The output shaft of the motors 2 drives the first screw rod 3 to rotate. Since the first screw rod 3 is threadedly connected to the middle of the connecting rod 4, when the first screw rod 3 rotates, it pushes the connecting rods 4 on both sides to move synchronously inward or outward along the guide rod 5. The lifting rod 7 at the top of the connecting rod 4 slides along the guide grooves on both sides of the bed board through the hinge structure. The guide grooves ensure that the movement trajectory of the slider 6 is smooth and avoid mechanical jamming. Since the tops of the lifting rods 7 on both sides are respectively connected to the top plate 9, the top plate 9 will rise or fall synchronously with the movement of the lifting rod 7.

[0041] The top plate 9 lifts up the two folded parts of the folding pad 8, and the middle reinforcing base plate 701 is fixed to the bed board, forming an inclination angle of 0° to 45° (error ≤ ±1°). The three-section structure of the folding pad 8 ensures even support for the patient's back, reduces pressure on the diaphragm, and avoids local suspension or pressure concentration. The foldable foam mattress 10 on the top of the folding pad 8 bends synchronously with the body position adjustment. Its internal memory foam material conforms to the curve of the patient's waist and back, reducing shear force.

[0042] After the air pump 14 is started, the airflow is delivered to the jet outlets at the head and foot of the bed through the jet tube 13. Part of the airflow output by the air pump 14 is injected into the airbag 22 through the diverter tube 18 and then through the second solenoid valve 19 to control the flow rate. After the airbag 22 is inflated, the pressure is evenly distributed through the skin-friendly cover 21, which focuses on supporting the bony prominences such as the sacrum, coccyx and scapula. The pressure relief regulator 20 monitors the pressure inside the airbag 22 in real time. If the pressure exceeds the standard, it will automatically release the air to prevent the risk of pressure sores.

[0043] Furthermore, the air pump 14 delivers filtered clean air to the nozzles at the head and foot of the bed through the jet pipe 13. The filter 15 inside the nozzle can intercept dust and pathogens. Multiple symmetrical nozzles in the nozzle blow airflow onto the patient's body to form an air layer that isolates the skin from the mattress, reducing friction and moisture. The first solenoid valve 17 can switch the airflow mode (continuous airflow or intermittent pulse) to prevent the skin from drying out.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
