Description

Technical Field

[0001] This application relates to the field of surgical equipment, specifically to an operating bed with temperature control and insulation functions. Background Technology

[0002] To provide uniform heat radiation to the patient's trunk or limbs during surgery and reduce the risk of hypothermia, existing operating tables typically use heating pads for warmth. However, these devices have drawbacks, such as a small contact area with the patient and easy heat loss. Therefore, inflatable warming blankets are increasingly being used for intraoperative patient warmth. These blankets utilize an adjustable air pressure inflatable bladder and a warm air control system. During surgery, an embedded control module adjusts the bladder pressure and airflow temperature in real time to ensure that the heat output conforms to the patient's body surface curve. Disposable bladders are used to ensure medical hygiene. However, current devices are mostly external warming devices, which not only occupy the intraoperative space but also restrict the movement and operation of medical staff due to the external air ducts. Furthermore, the disposable bladders require medical staff to use a large amount of adhesive tape, Velcro, and other auxiliary fixation tools to connect and seal the air ducts and bladders each time, making preoperative preparation and postoperative cleaning inconvenient and increasing the physical labor of medical staff.

[0003] Therefore, in order to solve the above problems, this application provides an operating table with temperature control and heat preservation function that integrates a heating device with the operating table to expand the intraoperative space and facilitates the connection of air ducts. Utility Model Content

[0004] The purpose of this invention is to provide an operating bed with temperature control and heat preservation functions, in order to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an operating bed with temperature control and heat preservation function, including a support frame, a bed body fixedly connected to the upper end of the support frame, a heat preservation blanket detachably connected to the upper part of the bed body, a heat preservation fan bolted to the side of the support frame, an air duct connected to the output end of the heat preservation fan, and an auxiliary mechanism for connecting the air duct and the heat preservation blanket at the rear end of the bed body.

[0006] The auxiliary mechanism includes a fixed tube, a connecting plate, and two sets of semi-circular clamps; the connecting plate is bolted to the tail of the bed, the outer periphery of the fixed tube is welded to the inner wall of the connecting plate, the clamps are slidably connected to the tail of the bed with a locking mechanism, and the end of the air duct away from the heat preservation fan is connected and fixed to the lower end of the fixed tube; the air inlet of the heat preservation blanket is fitted around the outer periphery of the fixed tube, and the clamps slide to clamp the air inlet of the heat preservation blanket on the outer periphery of the fixed tube.

[0007] By integrating the heat preservation fan onto the support frame and using a fixed tube at the rear of the bed to limit the air duct, both the air duct and the heat preservation fan remain under the bed, without occupying space during surgery. At the same time, by placing the air inlet of the heat preservation blanket on the fixed tube and using a clamp to directly squeeze and clamp it, the air duct and the heat preservation blanket are quickly connected and sealed by squeezing with a semi-circular clamp. This effectively reduces the operation steps of medical staff, reduces their labor intensity, and further improves the efficiency of preoperative preparation and postoperative cleaning.

[0008] Furthermore, the insulation blanket is made of disposable flexible material, and an air inlet is provided at the air inlet of the insulation blanket. The insulation blanket is tied to the bed frame. A controller is also provided, and the insulation fan is electrically connected to the controller to control the output speed and temperature of the insulation fan. The bed frame is a segmented bed frame, and the air duct is a flexible corrugated pipe.

[0009] Furthermore, the auxiliary mechanism also includes a through hole, a slot, a rotating rod, and threaded sleeves. The through hole is located at the rear end of the bed, and the rotating rod is rotatably connected to both ends of the through hole. Opposite-directed threads are provided on both sides of the center of the rotating rod, and two sets of threaded sleeves are threadedly connected to the rotating rod. The slot is located on the side of the through hole, and the clamping device is inserted into the threaded sleeve via a connecting rod passing through the slot. One end of the rotating rod extends outward through the side of the bed, and a handle is inserted into the outward-extending end of the rotating rod. Several sets of limiting protrusions are provided on both sides of the center of the rotating rod.

[0010] When the threaded rotating rod rotates, it drives two sets of threaded sleeves to move closer together, which in turn drives the semi-circular clamps to move closer together to clamp the fixed tube and the air inlet. The self-locking property of the threads is used to lock them, which effectively reduces the steps required for sealing the connection between the air inlet and the fixed tube, allowing medical staff to easily and quickly complete the pipeline connection.

[0011] Furthermore, the auxiliary mechanism also includes a sealing reinforcement component, which includes a receiving groove, a worm gear, a socket, a pin, and an elastic band. The receiving groove is opened above the through hole and communicates with the through hole. The worm gear is rotatably connected to the inner wall of the receiving groove. Two sets of sockets are symmetrically fixed to one side of the worm gear. The two ends of the elastic band are respectively tied to two sets of pins. The pins are inserted into the sockets. The middle part of the rotating rod is a worm structure, and the middle part of the rotating rod meshes with the worm gear.

[0012] By wrapping one end of the elastic band around the air inlet and inserting it into the socket, while turning the handle to clamp the pipe with the clamp, the worm gear is driven to rotate, causing the end of the elastic band to rotate and tighten. The tightening of the elastic band provides a secondary reinforcement seal for the air inlet, further enhancing the gas sealing effect.

[0013] Compared with existing technologies, it has the following beneficial effects:

[0014] This utility model provides an operating bed with temperature control and insulation function. By integrating the insulation fan onto the support frame and using a fixed tube at the rear end of the bed to limit the air duct, both the air duct and the insulation fan remain under the bed, without occupying space during surgery. At the same time, by placing the air inlet of the insulation blanket on the fixed tube and using a clamp to directly squeeze and clamp it, the air duct and the insulation blanket are quickly connected and sealed by the semi-circular clamp. This effectively reduces the operation steps of medical staff, reduces their labor intensity, and further improves the efficiency of preoperative preparation and postoperative cleaning.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5As shown, the present invention provides the following technical solution: an operating bed with temperature control and heat preservation function; including a support 1, a bed body 2 fixedly connected to the upper end of the support 1, a heat preservation blanket 3 detachably connected to the upper part of the bed body 2, a heat preservation fan 4 bolted to the side of the support 1, an air duct 5 connected to the output end of the heat preservation fan 4, and an auxiliary mechanism 6 for assisting in connecting the air duct 5 and the heat preservation blanket 3 at the tail end of the bed body 2;

[0023] The auxiliary mechanism 6 includes a fixed pipe 61, a connecting plate 62, and two sets of semi-circular clamps 63; the connecting plate 62 is bolted to the tail of the bed 2, the outer periphery of the fixed pipe 61 is welded to the inner wall of the connecting plate 62, the clamps 63 are slidably connected to the tail of the bed 2 with a locking mechanism, and the end of the air duct 5 away from the heat preservation fan 4 is connected and fixed to the lower end of the fixed pipe 61; the air inlet of the heat preservation blanket 3 is fitted around the outer periphery of the fixed pipe 61, and the clamps 63 slide to clamp the air inlet of the heat preservation blanket 3 on the outer periphery of the fixed pipe 61.

[0024] See Figure 1 The thermal blanket 3 is made of disposable flexible material, and an air inlet duct 31 is provided at the air inlet of the thermal blanket 3. The thermal blanket 3 is tied to the bed frame 2. The thermal blanket 3 is a disposable product that meets medical standards and can be discarded as medical waste after a single use. The support frame 1 is an electrically retractable support frame 1, which can be used to adjust the height of the bed frame 2 according to the surgical situation and the actual situation of the patient.

[0025] It should be noted that a controller is also provided, and the heating fan 4 is electrically connected to the controller to control the output rate and temperature of the heating fan 4. The heating fan 4 is a commonly used intraoperative heating fan 4 in existing technology, such as the 3M BairHugger™ powered air-inflating heating device. By installing the heating fan 4 at the bottom of the bracket 1 and using the electrical signal controller to remotely control the operating parameters of the heating fan 4, intraoperative space is saved and excessive equipment is avoided from being arranged around the bed 2.

[0026] See Figure 1 and Figure 2 The bed body 2 is a segmented bed body 2, and the air duct 5 is a flexible corrugated pipe. The segmented bed body 2 can be rotated at a certain angle to change the patient's lying posture, making it easier for medical staff to perform intraoperative operations and providing a clearer surgical field;

[0027] Meanwhile, the connecting plate 62, bolted to the tail end of the bed 2, limits the fixed pipe 61, allowing it to move synchronously with the tail end of the bed 2. Combined with the flexible corrugated pipe, this ensures effective communication between the air inlet of the insulation blanket 3 and the air duct 5 when the bed 2 is moved vertically or rotated as needed. The clamping device 63, moving synchronously with the bed 2, maintains effective clamping at all times. In use, the air inlet 31 is placed on the fixed pipe 61, and then the sliding semi-circular clamping device 63 clamps the fixed pipe 61 from both sides. The semi-circular clamping devices 63 close together to complete the clamping seal, and the insulation fan 4 delivers the insulation gas to the insulation blanket 3 through the air duct 5.

[0028] As another embodiment, such as Figures 3 to 5 As shown, the auxiliary mechanism 6 also includes a through hole 64, a slot 65, a rotating rod 66, and a threaded sleeve 67. The through hole 64 is located at the rear end of the bed 2. The rotating rod 66 is rotatably connected to both ends of the through hole 64. The rotating rod 66 has threads in opposite directions on both sides of its center. Two sets of threaded sleeves 67 are threadedly connected to the rotating rod 66. The slot 65 is located on the side of the through hole 64. The clamp 63 is inserted into the threaded sleeve 67 through the slot 65 via a connecting rod 68.

[0029] Among them, the threaded sleeve 67 and the through hole 64 have a limited sliding connection, which allows the threaded sleeve 67 to only move horizontally along the through hole 64 and cannot rotate. Since the threads on both sides of the center of the rotating rod 66 are in opposite directions, the internal threads of the threaded sleeve 67 that are threadedly connected to it are in opposite directions.

[0030] When the rotating rod 66 rotates, the threaded part rotates synchronously, driving the two sets of threaded sleeves 67 to move closer or further apart. The two sets of threaded sleeves 67 moving closer together cause the two sets of clamps 63 to move closer together and clamp and seal the air inlet 31 sleeved on the fixed tube 61, while using the self-locking property of the thread to lock it.

[0031] See Figure 3 One end of the rotating rod 66 extends outward through the side of the bed 2, and a handle 661 is inserted into the outward-extending end of the rotating rod 66. The position where the rotating rod 66 passes through the side of the bed 2 is rotatably connected to the bed 2. By rotating the handle 661, the rotating rod 66 can be rotated, thereby controlling the closing and unlocking of the clamp 63.

[0032] See Figure 4 An array of limiting protrusions 662 are provided on both sides of the center of the rotating rod 66. The function of the limiting protrusions 662 is to prevent the threaded sleeve 67 from excessive displacement, so that the threaded sleeve 67 can only move within a certain distance along the direction of the rotating rod 66.

[0033] As another embodiment, such as Figure 4 and Figure 5As shown, the auxiliary mechanism 6 also includes a sealing reinforcement component 69, which includes a receiving groove 691, a worm gear 692, a socket 693, a pin 694, and an elastic band 695. The receiving groove 691 is opened above the through hole 64 and communicates with the through hole 64. The worm gear 692 is rotatably connected to the inner wall of the receiving groove 691. Two sets of sockets 693 are symmetrically fixed to one side of the worm gear 692. The two ends of the elastic band 695 are respectively tied to two sets of pins 694, and the pins 694 are inserted into the sockets 693.

[0034] The connection between the pin 694 and the socket 693 is a detachable snap-fit ​​connection. Under normal conditions, the pin 694 at one end of the elastic band 695 is inserted into the socket 693, and the pin 694 on the other side of the elastic band 695 hangs down naturally. After the air inlet duct 31 is placed on the fixed tube 61, the pin 694 can be pulled to make the elastic band 695 pass around the air inlet duct 31 and insert the pin 694 into the socket 693, so that the elastic band 695 is placed on the air inlet duct 31.

[0035] See Figure 4 The middle part of the rotating rod 66 is a worm gear structure, and the middle part of the rotating rod 66 meshes with the worm wheel 692. The rotating rod 66 can be constructed by splicing threaded rods at both ends and a worm gear in the middle, or it can be a single integral rotating rod 66, with different areas treated separately. The rotating rod 66 is designed with threaded sections on both sides of the center and a worm gear section in the middle. The worm gear section and the threaded section are separated by a limiting protrusion 662. When the rotating rod 66 rotates, the worm gear section rotates synchronously, which in turn drives the worm wheel 692 in the receiving groove 691 to rotate. The rotation of the worm wheel 692 drives the socket 693 to rotate, which in turn drives the two ends of the elastic band 695 to rotate through the pin 694. The elastic band 695 is limited by the air inlet duct 31 and the fixed tube 61, so that the elastic band 695 is stretched and the ends are intertwined. This allows the elastic band 695 to play a role in assisting in fixing and strengthening the seal of the air inlet duct 31. At the same time, the clamp 63 at the bottom is driven to clamp the fixed tube 61 and the air inlet duct 31 normally.

[0036] Working principle: During use, the heat insulation blanket 3 is tied and fixed to the bed frame 2, with the air inlet 31 aligned with the rear of the bed frame 2. Then, the air inlet 31 is placed on the fixing tube 61. Pulling the pin 694 causes the elastic band 695 to pass around the air inlet 31, and the pin 694 is inserted into the socket 693, so that the elastic band 695 is placed on the air inlet 31. Turning the handle 661 causes the handle 661 to drive the rotating rod 66 to rotate. The threaded sleeve 67 is driven to move the two sets of semi-circular clamps 63 closer together and clamp the fixing tube 61 and the air inlet 31. At the same time, the worm gear 692 is driven by the worm to rotate, causing the elastic band to stretch and wrap, which assists in fixing and strengthens the seal of the air inlet 31. The heat insulation fan 4 is started to expand the heat insulation blanket 3. During the operation, the temperature and air pressure are continuously controlled by the controller. Before the operation, medical staff can also lay a sterile surgical drape on the operating table, which covers the warming blanket 3 to prevent infection during the operation; after the operation, stop the warming fan 4, and reverse the handle 661 to unlock the device, and collect and dispose of the warming blanket 3.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
