Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a treatment bed for oral clinical medicine. Background Art

[0002] In oral surgery, ensuring a sterile environment in the surgical area is one of the key factors for a successful operation. In order to protect the patient's face and keep the surgical area clean, it is usually necessary to cover the face with a surgical drape, leaving only the oral cavity exposed. However, there are some problems with the traditional way of fixing surgical drapes. In the prior art, a drape clamp is often used to fix the surgical drape on the patient's face, but this method can easily cause damage to the patient's skin and hair, and during the operation, the surgical drape may slide or shift due to the patient's facial movement or interference from surgical instruments, thereby affecting the surgical operation and the maintenance of a sterile environment.

[0003] In order to solve the above problems, the prior art (such as patent CN115120461A) proposes a method of fixing the surgical drape on the patient's face through the elastic pressure of a rubber strip, avoiding the scratch problem caused by using a cloth towel clamp. This method fixes the drape on the patient's forehead and chest through a rubber strip, which preliminarily solves the problem of drape fixation, but there are still shortcomings. Due to the complex contour of the face, the rubber strip is not firm when fixing the hole, and the hole of the surgical drape is not effectively pressed and limited, resulting in the risk of sliding and displacement during the operation, which not only affects the smooth progress of the operation, but also may increase the risk of infection.

[0004] In addition, existing fixation methods often lack flexibility in actual operation and cannot be effectively adjusted according to the shape and size of different patients' faces. This limitation requires medical staff to spend extra time and energy to adjust the position and tightness of the surgical drape during surgical preparation, which increases the complexity of surgical preparation. Summary of the invention

[0005] The technical problem to be solved by the present invention is to propose an improved oral clinical medical treatment bed, which ensures the firm fixation of the surgical drape by designing a reasonable winding and pressing mechanism to avoid sliding or shifting during the operation, while improving the efficiency of surgical preparation and reducing pressure and discomfort on patients.

[0006] To achieve the above-mentioned object, the present invention provides a treatment bed for oral clinical medicine, comprising a bed body and fixed plates arranged on both sides of the bed body, wherein the fixed plates are provided with fixed blocks, the side surfaces of the fixed blocks are provided with a first winding mechanism, the top surface of the fixed blocks is provided with a second winding mechanism, and a pressing mechanism is provided between the two second winding mechanisms.

[0007] The first winding mechanism includes a side plate welded and fixed on the side of the fixed block, and a first winding drum movably connected to the side plate bearing, the first winding drum is connected to the second winding drum, the second winding drum is connected to the third winding drum, and buckles are clamped on the outer walls of the first winding drum and the third winding drum.

[0008] The second winding mechanism comprises a fixed frame slidably connected to the fixed block, and a rotating shaft connected to the fixed frame bearing, a fixed column is sleeved on the rotating shaft, a winding shaft is sleeved on the fixed column, an elastic rope is wound and fixed on the winding shaft, and a locking mechanism is arranged at one end of the winding shaft.

[0009] The pressing mechanism comprises a pressing pad, which is formed by a first pressing part and a second pressing part surrounding each other end to end, a first adjusting wire is arranged inside the first pressing part, a second adjusting wire is arranged inside the second pressing part, and the first adjusting wire and the second adjusting wire are an integrated structure.

[0010] The first pressing portion at the top end of the first adjusting wire is connected to the elastic rope through an elastic connector.

[0011] As the preferred technical solution:

[0012] In the oral clinical medical treatment bed as described above, the fixing block is provided with a slot facing one side of the fixing plate, the fixing block and the slot are both "C" shaped, and a locking bolt is screwed into the thread of the bottom end wall of the fixing block.

[0013] Through the above technical solution, the shape design of the fixing block and the slot ensures that the fixing block will not touch the bolts between the bed body and the fixing plate during installation.

[0014] In the oral clinical medical treatment bed as described above, the first winding drum and the second winding drum are both hollow structures, the inner diameters of the first winding drum, the second winding drum and the third winding drum gradually decrease, and the buckles on the first winding drum and the third winding drum are in a "C" shape.

[0015] Through the above technical solution, the buckle is made of plastic material, which has a certain elasticity, and its shape is designed so that after the surgical drape is wound on three winding drums, the buckle can be fastened on the first winding drum and the third winding drum, so that the surgical drape can be fixed on the three winding drums, and then the surgical drape can be continuously wound when winding.

[0016] As described above, the oral clinical medical treatment bed, the first winding drum has a first through hole at the head end thereof for the second winding drum to pass through, and the second winding drum has a second through hole at the head end thereof for the third winding drum to pass through;

[0017] The end of the second winding drum is sleeved with a first limiting ring welded and fixed thereto, and the end of the third winding drum is sleeved with a second limiting ring welded and fixed thereto;

[0018] The outer circular wall of the first limiting ring is in contact with the inner wall of the first winding drum, and the outer circular wall of the second limiting ring is in contact with the inner wall of the second winding drum.

[0019] Through the above technical solution, the first limiting ring is set so that the second winding drum will not fall off from the first winding drum when the second winding drum moves telescopically inside the first winding drum.

[0020] The second limiting ring is provided so that the third winding drum will not fall off the second winding drum when the third winding drum moves telescopically inside the second winding drum, thereby improving the integrity of the first winding drum, the second winding drum and the third winding drum.

[0021] In the oral clinical medical treatment bed as described above, a long guide rail is fixed to the top of the fixed block, a long sliding block is welded and fixed to the bottom of the fixed frame, the cross section of the sliding block is in an inverted "T" shape, and a sliding groove adapted to the sliding block is opened on the guide rail.

[0022] Through the above technical solution, the sliding block is embedded in the sliding groove, and the sliding block can slide linearly in the sliding groove, and then the fixed frame can move linearly along the guide rail through the sliding block, and the structure is reasonable.

[0023] In the above-mentioned oral clinical medical treatment bed, the fixing column is provided with a first hole slot penetrating the fixing column, and the rotating shaft passes through the first hole slot and is fixed to the fixing column by welding;

[0024] The winding shaft is provided with a second hole slot penetrating through the winding shaft, and the fixing post passes through the second hole slot and is slidably connected to the winding shaft;

[0025] The fixing column and the second hole groove are both in the shape of a rectangular column.

[0026] Through the above technical solution, the shape design of the fixing column and the second hole groove allows the winding shaft to not only move along the axis of the fixing column, but also synchronously drive the winding shaft to rotate axially when the fixing column rotates.

[0027] In the above-mentioned oral clinical medical treatment bed, the locking mechanism comprises a third hole slot provided at one end of the rotating shaft, and a rotating rod inserted into the third hole slot, and the end surface of the rotating rod inserted into the third hole slot is welded to the slot wall of the third hole slot via an elastic spring;

[0028] The cross sections of the third hole and the rotating rod are both rectangular.

[0029] Through the above technical solution, the cross-sectional shape design of the third hole groove and the rotating rod enables the rotating rod to not only move linearly along the third hole groove, but also transmit torque between the rotating rod and the rotating shaft, that is, the rotating rod and the rotating shaft can rotate synchronously.

[0030] In the oral clinical medical treatment bed as described above, the locking mechanism also includes a locking cover sleeved on the rotating rod, the locking cover is a hollow cylindrical structure, the side of the locking cover facing the fixed frame is open, and the open end surface of the locking cover is frosted.

[0031] Through the above technical solution, when the open end of the locking cover fits against one side of the fixed frame, friction can be generated on the contact surface of the two, and the friction can prevent the rotating shaft from rotating, ensuring that the rotating shaft can remain fixed after rotation.

[0032] In the above-mentioned oral clinical medical treatment bed, the pressing pad, the elastic rope and the elastic connector are all made of silicone material, the elastic connector is in a "Y" shape, the two branches at the head end of the elastic connector are fixedly bonded to the first pressing part, and the terminal branch of the elastic connector is fixedly bonded to the first connecting block;

[0033] The end of the elastic rope not connected to the winding shaft is fixedly bonded with a second connecting block, the first connecting block is provided with a threaded hole, and the surface of the second connecting block is provided with threads and is threadedly connected to the threaded hole.

[0034] Through the above technical solution, the second connecting block is threadedly connected to the threaded hole, so that the second connecting block and the first connecting block are a detachable installation structure. By separating the second connecting block from the first connecting block, the pressing pad can be removed separately, which is convenient for disinfection of the pressing pad to ensure the safety of the operation.

[0035] In the oral clinical medical treatment bed as described above, two first adjusting wires are symmetrically arranged about the first pressing part, and the first adjusting wire and the second adjusting wire are metal wires.

[0036] Through the above technical solution, the first adjusting wire and the second adjusting wire can be iron wire, copper wire, etc. The metal wire has good plasticity and durability. In this way, after the first adjusting wire and the second adjusting wire are twisted, both can maintain the twisted shape, so that the compression pad can fit the patient's face better and avoid sliding and deviation of the surgical drape.

[0037] Compared with the prior art, the present invention has at least the following beneficial effects:

[0038] (1) Secure fixation of surgical drapes to prevent sliding and displacement: The present invention forms an effective surgical drape fixing system by providing a first winding drum, a second winding drum, and a third winding drum. The surgical drapes are securely fixed to both sides of the bed through the synergistic effect of the three winding drums, avoiding the risks of using clips in traditional fixing methods, such as damage to the patient's skin. At the same time, this winding structure can prevent the drapes from sliding or displacing during surgery, ensuring the stability of the surgical environment and the continuity of aseptic operation.

[0039] (2) Comfortable design of the compression pad improves patient experience: The compression pad of the present invention is made of soft silicone material with good elasticity and softness. When the compression pad is used to fix the hole of the surgical drape, it can effectively avoid excessive pressure on the patient's face and reduce discomfort. At the same time, the silicone material can fit the patient's face tightly, providing a comfortable compression experience, which is particularly suitable for patients with different facial contours and improves the patient's comfort.

[0040] (3) Adjustable compression structure to adapt to different facial shapes: The compression pad is equipped with an adjustable wire inside, which can be adjusted according to the facial shape of different patients. By changing the shape and size of the wire, the compression pad can flexibly adapt to different facial contours and ensure that the surgical drape remains stable during the operation. This design not only improves the applicability of the equipment, but also reduces the time for surgical preparation.

[0041] (4) Quick adjustment and fixing function to simplify the surgical preparation process: The present invention has designed a simple winding and pressing mechanism, which allows medical staff to quickly adjust the tightness and pressing position of the surgical drape to flexibly meet the needs of different surgeries. The sliding design of the fixing block and the guide rail enables the pressing mechanism to move on both sides of the bed, greatly improving the efficiency of surgical preparation and reducing adjustment time.

[0042] (5) Easy to clean and maintain, in compliance with hygiene standards: The compression pad and other components of the present invention are all detachable, which is convenient for disinfection and cleaning after the operation, ensuring that the equipment meets medical hygiene standards. The durable silicone material allows the equipment to be reused, reducing medical costs and reducing the use of disposable materials, meeting environmental protection requirements.

DETAILED DESCRIPTION

[0052] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0053] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0054] See also Figure 1 , Figure 2 and Figure 6 The present invention provides a technical solution: a treatment bed for oral clinical medicine, comprising a bed body 1, and fixed plates 2 arranged on both sides of the bed body 1, a fixed block 3 is arranged on the fixed plate 2, a first winding mechanism is arranged on the side of the fixed block 3, a second winding mechanism is arranged on the top surface of the fixed block 3, and a pressing mechanism is arranged between the two second winding mechanisms.

[0055] The first winding mechanism includes a side plate 4 welded and fixed on the side of the fixed block 3, and a first winding drum 5 movably connected to the bearing of the side plate 4, the first winding drum 5 is connected to the second winding drum 6, the second winding drum 6 is connected to the third winding drum 7, and buckles 10 are clamped on the outer walls of the first winding drum 5 and the third winding drum 7.

[0056] The second winding mechanism includes a fixed frame 13 slidably connected to the fixed block 3, and a rotating shaft 14 bearing-connected to the fixed frame 13, a fixed column 15 is sleeved on the rotating shaft 14, a winding shaft 17 is sleeved on the fixed column 15, an elastic rope 23 is wound and fixed on the winding shaft 17, and a locking mechanism is provided at one end of the winding shaft 17.

[0057] The pressing mechanism includes a pressing pad 24, which is formed by a first pressing part 32 and a second pressing part 33 surrounding each other end to end. A first adjusting wire 25 is arranged inside the first pressing part 32, and a second adjusting wire 26 is arranged inside the second pressing part 33. The first adjusting wire 25 and the second adjusting wire 26 are an integrated structure.

[0058] The first pressing part 32 at the top of the first adjusting wire 25 is connected to the elastic rope 23 through the elastic connector 27. Two first adjusting wires 25 are symmetrically arranged about the first pressing part 32. The first adjusting wire 25 and the second adjusting wire 26 are metal wires.

[0059] Before the operation, the patient is first allowed to lie flat on the bed 1, and then the fixing blocks 3 are installed on the fixing plates 2 on both sides of the bed 1, and then the first winding drum 5, the second winding drum 6 and the third winding drum 7 are stretched.

[0060] Then, the surgical drape is covered on the patient's body, and the hole of the surgical drape is moved to the patient's mouth, and then the two ends of the surgical drape are wound on the first winding drum 5, the second winding drum 6 and the third winding drum 7, and the surgical drape is wound by the first winding drum 5, the second winding drum 6 and the third winding drum 7. During the winding process, the surgical drape will gradually tighten and fit the patient's body, so that the surgical drape can cover the patient flatly.

[0061] Then slide the fixing frame 13 on the fixing block 3, and move the fixing frame 13 to a suitable position so that the pressing pad 24 can be located just above the hole of the surgical drape. At this time, the shape and size of the pressing pad 24 can be changed by twisting the first adjusting wire 25 and the second adjusting wire 26. In the initial state, the second adjusting wire 26 is in a "V" shape. When the second adjusting wire 26 is deformed from a "V" shape to an "I" shape, the distance between the two first pressing parts 32 can be increased, that is, the overall width of the pressing pad 24 can be increased.

[0062] Since the two first adjustment wires 25 in the first pressing part 32 are not a whole, the first pressing part 32 between the two first adjustment wires 25 can be elastically deformed, so that the two elastic ropes 23 can be wound and tightened by the second winding mechanism, and the two elastic ropes 23 synchronously pull the elastic connecting parts 27. The two elastic connecting parts 27 can stretch the first pressing part 32 between the two first adjustment wires 25, so that the distance between the two second pressing parts 33 can be increased, that is, the overall length of the pressing pad 24 can be increased.

[0063] When the size adjustment is completed, the first adjustment wire 25 and the second adjustment wire 26 can be twisted and deformed so that the first pressing part 32 and the second pressing part 33 can better fit the patient's face. In this way, the pressing pad 24 can better press the surgical drape to prevent the surgical drape from sliding during the operation, thereby ensuring the smooth progress of the operation.

[0064] like Figure 3 As shown, a slot 31 is provided on the fixing block 3 facing the fixing plate 2 , and both the fixing block 3 and the slot 31 are “C” shaped, and a locking bolt is screwed into the bottom wall of the fixing block 3 .

[0065] Due to the arrangement of the card slot 31, when installing the fixing block 3, the fixing plate 2 can be inserted into the card slot 31, and then the fixing block 3 can be slidably sleeved on the fixing plate 2, which facilitates the installation and disassembly of the fixing block 3. When the fixing block 3 is installed, the locking bolt can be screwed in, and the end of the locking bolt is pressed against the fixing plate 2, which can prevent the fixing block 3 from sliding on the fixing plate 2.

[0066] like Figure 2 As shown, the first winding drum 5 and the second winding drum 6 are both hollow structures, the inner diameters of the first winding drum 5, the second winding drum 6 and the third winding drum 7 gradually decrease, and the buckles 10 on the first winding drum 5 and the third winding drum 7 are in a "C" shape.

[0067] A first through hole for the second winding drum 6 to pass through is formed at the head end of the first winding drum 5 , and a second through hole for the third winding drum 7 to pass through is formed at the head end of the second winding drum 6 .

[0068] A first limiting ring 8 is sleeved and fixedly welded to the end of the second winding drum 6 , and a second limiting ring 9 is sleeved and fixedly welded to the end of the third winding drum 7 .

[0069] The outer circular wall of the first limiting ring 8 fits with the inner wall of the first winding drum 5 , and the outer circular wall of the second limiting ring 9 fits with the inner wall of the second winding drum 6 .

[0070] The hollow design of the first winding drum 5 and the second winding drum 6 allows the second winding drum 6 to be telescopically movable inside the first winding drum 5, and the third winding drum 7 to be telescopically movable inside the second winding drum 6. The outer circular walls of the first limiting ring 8 and the second limiting ring 9 are bonded with rubber rings, and the first limiting ring 8 and the second limiting ring 9 are in contact with the inner walls of the second winding drum 6 and the third winding drum 7 through the rubber rings, so that friction can be generated through the rubber rings. Due to the existence of friction, the extension and retraction of the second winding drum 6 and the third winding drum 7 require external force, so as to avoid the second winding drum 6 and the third winding drum 7 shrinking by themselves during the operation and affecting the laying effect of the surgical drape.

[0071] At the same time, through friction, torque can be transmitted between the first winding drum 5 and the second winding drum 6 and between the second winding drum 6 and the third winding drum 7, so that the first winding drum 5, the second winding drum 6 and the third winding drum 7 can rotate synchronously, ensuring the winding effect of the surgical drape.

[0072] like Figure 3 As shown, a long guide rail 11 is fixed to the top of the fixed block 3, and a long sliding block 12 is welded and fixed to the bottom of the fixed frame 13. The cross section of the sliding block 12 is in an inverted "T" shape, and a sliding groove adapted to the sliding block 12 is opened on the guide rail 11.

[0073] The sliding block 12 can slide linearly in the sliding groove, so that the fixed block 3 can slide linearly along the guide rail 11, so that the position of the fixed frame 13 can be freely adjusted. When the surgical drape is wound by the first winding drum 5, the second winding drum 6 and the third winding drum 7, the fixed frame 13 can be moved away to avoid the fixed frame 13 from hindering the winding of the surgical drape.

[0074] like Figure 3 , Figure 4 and Figure 5 As shown, the fixing column 15 is provided with a first hole groove 16 penetrating through the fixing column 15, and the rotating shaft 14 passes through the first hole groove 16 and is welded and fixed to the fixing column 15; the winding shaft 17 is provided with a second hole groove 18 penetrating through the fixing column 15, and the fixing column 15 passes through the second hole groove 18 and is slidably connected to the winding shaft 17; the fixing column 15 and the second hole groove 18 are both rectangular columnar.

[0075] The fixed frame 13 can slide on the fixed block 3, and the position of the winding shaft 17 can be adjusted through the fixed frame 13. Since the moving range of the fixed frame 13 is limited, in order to increase the moving range of the winding shaft 17, the winding shaft 17 can also move on the fixed column 15, thereby ensuring that the pressing pad 24 can move above the hole of the surgical drape.

[0076] When the rotating shaft 14 rotates, it can directly drive the fixed column 15 to rotate. Since the cross-sections of the fixed column 15 and the second hole groove 18 are both rectangular, torque can be transmitted between the fixed column 15 and the winding shaft 17, and the fixed column 15 can drive the winding shaft 17 to rotate synchronously.

[0077] like Figure 4 and Figure 5 As shown, the locking mechanism includes a third hole groove 19 opened at one end of the rotating shaft 14, and a rotating rod 20 inserted into the third hole groove 19. The end surface of the rotating rod 20 inserted into the third hole groove 19 is welded to the groove wall of the third hole groove 19 through an elastic spring 21; the cross-sections of the third hole groove 19 and the rotating rod 20 are both rectangular.

[0078] The locking mechanism further includes a locking cover 22 sleeved on the rotating rod 20. The locking cover 22 is a hollow cylindrical structure. The side of the locking cover 22 facing the fixed frame 13 is open, and the open end surface of the locking cover 22 is frosted.

[0079] When rotating the rotating shaft 14, you must first pull the rotating rod 20, which moves linearly in the third hole groove 19 and stretches the elastic spring 21. When the rotating rod 20 moves, it will drive the locking cover 22 to move synchronously, so that the locking cover 22 is separated from the fixed frame 13. Then, the rotating rod 20 is twisted, and the rotating rod 20 can drive the rotating shaft 14 to rotate synchronously. When it is rotated to a suitable position, the rotating rod 20 is released. Under the elastic force of the elastic spring 21, the rotating rod 20 will be pulled to reset, and then the locking cover 22 will be synchronously reset and abut against the fixed frame 13 again. The friction force generated between the locking cover 22 and the fixed frame 13 can limit the rotating shaft 14. In the above manner, medical staff can quickly complete the locking operation, which is convenient and fast.

[0080] like Figure 1 and Figure 7 As shown, the pressing pad (24), the elastic rope (23) and the elastic connecting piece (27) are all made of silicone material, the elastic connecting piece (27) is in a "Y" shape, the two branches at the head end of the elastic connecting piece (27) are fixedly bonded to the first pressing portion (32), and the terminal branch of the elastic connecting piece (27) is fixedly bonded to the first connecting block (28); the end of the elastic rope (23) not connected to the winding shaft (17) is fixedly bonded to the second connecting block (30), the first connecting block (28) is provided with a threaded hole (29), and the surface of the second connecting block (30) is provided with threads and is threadedly connected to the threaded hole (29).

[0081] The design of the silicone material not only makes the compression pad (24), the elastic rope (23) and the elastic connector (27) have good elasticity, but also makes the material soft. Thus, when the compression pad (24) is fitted onto the patient's face, the pressure of the compression pad (24) on the patient's face can be greatly reduced, thereby avoiding causing discomfort to the patient.

[0082] The first connecting block (28) and the second connecting block (30) are connected by threads to form a whole, which is not only convenient for disassembly to sterilize the pressing pad (24) separately, but also the first connecting block (28) and the second connecting block (30) are firmly connected and difficult to separate, so that the elastic connecting piece (27) can be pulled by the elastic rope (23).

[0083] The shape design of the elastic connecting pieces (27) allows the two ends of the two first pressing parts (32) to be stretched through the two elastic connecting pieces (27).

[0084] In the description of this specification, "connection", "installation", "fixation" and the like should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
