Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a hospital bed for thoracentesis. Background Technology

[0002] Thoracentesis is a common, convenient, and simple diagnostic and treatment procedure for pleural effusion.

[0003] Currently, when performing thoracentesis, medical staff usually have the patient get out of bed and sit backwards in a chair with a backrest to expose their back for the procedure. However, this method is not suitable for critically ill patients or those with lower limb mobility impairments who are unable to get out of bed. Therefore, in existing technical solutions, a swingable and adjustable bed is generally used to assist patients in thoracentesis.

[0004] However, when the hospital bed is raised, patients, especially those with disabilities, are prone to slipping to one side, affecting subsequent punctures. To prevent patients from tilting and slipping, multiple medical staff need to work together to stabilize the patient and assist with the puncture. Moreover, the patient's position is still prone to change during the puncture, affecting the puncture effect. Furthermore, after the bed is raised, the patient's back is usually facing the head of the bed, requiring medical staff to walk around to the head of the bed to perform the puncture, which is inconvenient for them. At the same time, during ultrasound-guided punctures, due to the different body shapes of patients, it may be necessary to make minor adjustments to the angle of the patient. However, disabled patients cannot actively adjust their sitting posture, and it is inconvenient for medical staff to manually assist and adjust them. Summary of the Invention

[0005] In view of this, the present invention provides a bed for thoracentesis, wherein the anti-slip ends of two anti-slip components move in opposite directions to abut against the left and right sides of the patient's chest cavity to prevent the patient from slipping when sitting up, thereby avoiding affecting the subsequent puncture effect.

When the two fixing blocks are in the storage position, they are flush with the front of the second bed body, and when they are in the protruding position, they protrude from the front of the second bed body.

[0023] The two third drive components are used to drive the two fixed blocks to switch back and forth between the storage station and the protrusion station.

[0024] One end of the fixation strap is fixed to the fixation block, and the other end is used to insert into another fixation block to fix the patient's abdomen.

[0025] Preferably, both of the fixing slots are elongated slots, and the two fixing blocks can slide horizontally within the two fixing slots;

In the first work position, the first bed body is parallel to the bed frame and in the second work position, it is perpendicular to the bed frame.

[0031] The bed for thoracentesis also includes a fourth drive assembly, which drives the first bed body to switch back and forth between a first working position and a second working position.

[0032] The second bed body has a through back groove in the middle part, and the two anti-slip components are located on both sides of the back groove.

[0033] The bed also includes a back panel that can be detachably installed in the back slot of the second bed.

[0034] Preferably, the middle part of the first bed body has two parallel first through slots, the two first through slots are close to the front end of the first bed body and are perpendicular to the rotation axis of the second bed body;

[0035] The bed also includes two cover plates, which are detachably installed in the slots of the two first through slots of the first bed.

[0036] Preferably, it further includes: a support column, a fixing plate, and a fifth drive assembly;

[0037] The support column is rotatably mounted on the bed frame around a first horizontal direction;

[0038] The fixing plate is disposed at the top of the support column;

[0039] The first bed body is rotatably mounted on the fixed plate in a vertical direction;

[0040] The fifth drive assembly is disposed on the bed frame and is used to drive the fixed disc to rotate about a first horizontal direction; wherein, the first horizontal direction is parallel to the rotation axis of the second bed body.

[0041] Preferably, it further includes a support assembly, which includes: a support rod, a support plate, and a sixth drive assembly;

[0042] A storage groove is provided in the middle part of the front of the first bed body along the second horizontal direction;

[0043] The first end of the support rod is rotatably disposed at one end of the storage slot around the first horizontal direction, and has a switchable storage position and a support position. When the support rod is in the storage position, it is located inside the storage slot, and when it is in the support position, it protrudes outside the storage slot. The first horizontal direction is parallel to the rotation axis of the second bed and perpendicular to the second horizontal direction.

[0044] The sixth drive component is used to drive the rotation of the first end of the support rod, so that the support rod can switch back and forth between the storage position and the support position.

[0045] The support plate is detachably installed on the second end of the support rod when the support rod is switched to the support position.

[0046] Preferably, it further includes two handrail assemblies, each comprising: a sliding block, a rotating rod, a handrail bar, a first locking member, a second locking member, and a third locking member;

[0047] The first bed body has first sliding grooves on both sides of the back side along the first horizontal direction, and these grooves are respectively connected to the left and right ends of the first bed body.

[0051] As can be seen from the above technical solution, the thoracentesis bed provided by the present invention can drive the second bed body to rotate through the first driving component to assist the patient to sit up. In this process, the anti-slip ends of the two anti-slip components move in opposite directions to abut against the left and right sides of the patient's chest cavity to prevent the patient from slipping when sitting up, thereby avoiding affecting the subsequent puncture effect.

Detailed Implementation

[0067] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0068] The thoracentesis bed provided in this embodiment of the invention includes: a bed frame, a bed body, a first drive assembly, and two anti-slip assemblies;

[0069] like Figure 4 As shown, the bed body includes: a first bed body 11 and a second bed body 12;

[0070] The first bed body 11 is mounted on the bed frame;

[0071] The second bed 12 is rotatably disposed on the first bed 11 and can rotate relative to the first bed 11 under the drive of the first drive assembly.

[0072] Two anti-slip components are respectively located on both sides of the second bed body 12, and their anti-slip ends can move towards each other to abut against both sides of the patient's chest cavity.

[0073] It should be noted that, as Figure 1 and Figure 5 As shown, the bed frame includes: a first support 10, two second supports 18, and two third supports 19. The two second supports 18 are located on the front side and are arranged symmetrically from left to right. The first support 10 is located on the rear side, and each side of the first support 10 is connected and fixed to the second supports 18 via the third supports 19. Figure 4 As shown, the first bed body 11 can be mounted on two second supports 18; the front end of the second bed body 12 can be hinged to the rear end of the first bed body 11; wherein, as Figure 6 As shown, hinge plates 58 can be provided on both sides of the front end of the second bed body 12, and hinge slots can be provided on both sides of the rear end of the first bed body 11. The two hinge plates 58 on the front end of the second bed body 12 can be hinged to the two hinge slots on the rear end of the first bed body 11 through a rotating shaft. There can be two first drive components, which are respectively provided on both sides of the back of the first bed body 11 and are used to drive the two hinge plates 58 to rotate or flip. Of course, the side of the second bed body 12 used for the patient to lie down or sit is the front, and the other side facing away from the patient is the back or bottom.

[0074] Specifically, such as Figure 6As shown, the first drive assembly can be in the form of a lead screw assembly + a swing arm, and may include: a first motor 59, a first screw 25, a threaded block 60, a guide rod, and a swing arm 62; the first motor 59 can be disposed downward on the back of the first bed 11 and located on one side of the corresponding hinge slot; the first screw 25 is disposed vertically, and its upper end is connected to the output shaft of the first motor 59; the guide rod is disposed vertically on the back of the first bed 11; the first screw 25 and the guide rod respectively pass through the threaded block 60, and the first screw 25 and the threaded block 60 are threadedly engaged, and the threaded block 60 can slide up and down along the guide rod; a connecting block may be provided at the bottom of the hinge plate 58; one end of the swing arm 62 can be rotatably connected (hinged) to the side end of the threaded block 60, and the other end can be rotatably connected (hinged) to the side end of the connecting block of the corresponding hinge plate 58; wherein, the first motor 59 can be used to drive the first drive assembly. The first motor 59 drives the first screw 25 to rotate, which in turn drives the threaded block 60 to slide along the first screw 25. Then, the swing arm 62 drives the hinge plate 58 to rotate or flip, thereby achieving the flipping and lifting of the second bed 12. Of course, the first motor 59 can rotate in both directions to drive the second bed 12 to rise and return, and it can also have a self-locking function. Of course, the first bed 11 and the second bed 12 are both in a horizontal state under normal conditions, so that the first bed 11 and the second bed 12 form a bed surface for the patient to lie on. When thoracentesis is required, the first motor 59 is started, causing the first screw 25 to rotate, which in turn drives the threaded block 60 to move up and down. Then, the threaded block 60 pulls the swing arm 62, which in turn pulls the hinge plate 58 to rotate or flip, thereby achieving the effect of rotating and lifting the second bed 12 so that the patient can sit up.

[0075] Two anti-slip components can be respectively installed on both sides of the front of the second bed 12, and their anti-slip ends can move towards each other to abut against the left and right sides of the patient's chest cavity respectively. In this way, during the rotation and raising of the second bed 12, the patient can be prevented from sliding sideways when sitting up, which can also prevent the patient from tilting and slipping when sitting up, thus avoiding affecting the subsequent puncture effect. Of course, this solution uses two anti-slip components to replace multiple medical staff to restrain the left and right sides of the patient's chest cavity, which can help reduce labor costs. Of course, both anti-slip components can be equivalent to anti-side slip components.

[0076] In other words, the thoracentesis bed provided by this solution can drive the second bed body 12 to rotate through the first drive component to assist the patient in sitting up. During this process, the anti-slip ends of the two anti-slip components move in opposite directions to abut against the left and right sides of the patient's chest cavity to prevent the patient from slipping when sitting up, thereby avoiding affecting the subsequent puncture effect.

[0077] In this plan, such as Figure 10 As shown, both anti-slip components include: an anti-slip shell 22, an anti-slip plate 30, and a side-push assembly;

[0078] like Figure 4 As shown, two anti-slip shells 22 are respectively disposed on both sides of the front of the second bed body 12, and openings are provided on the opposite side ends;

[0079] Two side-push components are installed inside two anti-slip shells 22, and their movable ends can move towards each other and protrude out of the anti-slip shells 22 through the openings;

[0080] Two anti-slip plates 30 are respectively installed at the movable ends of the two side-push components, and each has a switchable storage position and a contact position, such as... Figure 4 As shown, both anti-slip plates 30 are located inside the anti-slip shell 22 when in the storage position, and abut against the two sides of the patient's chest cavity when in the contact position.

[0081] It should be noted that, as Figure 4 As shown, two anti-slip shells 22 can be respectively installed on the left and right sides of the front of the second bed body 12, and the two are distributed opposite each other, and the opposite sides of the two anti-slip shells 22 are provided with openings (such as...). Figure 10 As shown), both anti-slip shells 22 have openings at their closest points; naturally, the two anti-slip shells 22 are located on the left and right sides of the patient's chest cavity, respectively, and the openings of the anti-slip shells 22 communicate with their inner cavities; among them, as... Figure 10 As shown, the anti-slip shell 2 can be a box-shaped structure;

[0082] Two side-push components are respectively disposed on the inner sidewalls of the two anti-slip shells 22 (the two side-push components are distributed opposite to each other), and the movable ends of the two side-push components can move towards each other and protrude (extend) from the anti-slip shells 22 through the openings; specifically, such as Figure 11 As shown, both side-push assemblies may each include: two first hydraulic cylinders 31; wherein, the two first hydraulic cylinders 31 may be respectively vertically arranged on the inner side wall of the anti-slip shell 22, and each first hydraulic cylinder 31 has a first telescopic rod 32; of course, the side-push assembly uses two first hydraulic cylinders 31 so as to smoothly push the anti-slip plate 30 out of the anti-slip shell 22 and abut against one side of the patient's chest cavity.

[0083] Each anti-slip plate 30 can be installed at the movable end of the first telescopic rod 32 of the two first hydraulic cylinders 31 (e.g., Figure 11 As shown), both have switchable storage and contact positions; in the storage position, both anti-slip plates 30 are located inside the anti-slip shell 22 (as shown). Figure 10As shown), when the two anti-slip plates 30 are in contact with each other, they are located outside the anti-slip shell 22 and are used to contact the left and right sides of the patient's chest cavity respectively. This is equivalent to locking the left and right sides of the patient's chest cavity, thereby restraining the left and right sides of the patient's chest cavity and preventing the patient from sliding sideways when sitting up. In addition, soft pads can be installed on the side ends of the two anti-slip plates 30 that are close to each other, so as to provide a cushioning effect when contacting each other. The soft pads can be made of sponge material or inflatable pads to ensure that the patient feels a soft touch when in contact with the soft pads.

[0084] In other words, this solution uses two opposing anti-slip plates 30 as two anti-slip components. The structure is simple and the anti-slip is convenient. Moreover, the two anti-slip plates 30 can be stored in the corresponding anti-slip shell 22, which makes the structure of the two anti-slip components compact and not obtrusive, which helps to ensure that the hospital bed has a good appearance.

[0085] Specifically, anti-slip grooves are provided on both sides of the front of the second bed body 12;

[0086] Two anti-slip shells 22 are slidably installed in two anti-slip grooves, each with a switchable storage position and an extended position. When in the storage position, both anti-slip shells 22 are flush with the front of the second bed 12. Figure 4 As shown, when protruding from the work station, its openings all protrude from the front of the second bed body 12;

[0087] Both anti-slip components also include a second drive component;

[0088] Two second drive components are respectively located on both sides of the back of the second bed 12, and are used to drive the two anti-slip shells 22 to switch back and forth between the storage position and the protrusion position.

[0089] It should be noted that, as Figure 10 As shown, the anti-slip shell 22 can be a rectangular box-shaped structure; correspondingly, as... Figure 4 As shown, rectangular anti-slip grooves can be opened on both sides of the front of the second bed body 12, and their cross-sectional shape is adapted to the cross-sectional shape of the anti-slip shell 22; the two anti-slip shells 22 are slidably disposed in the two anti-slip grooves of the second bed body 12; wherein, the sliding direction of the anti-slip shell 22 is the normal direction of the front or back of the second bed body 12, that is, the direction perpendicular to the front or back of the second bed body 12, so as to form a switchable storage position and an extension position; when the two anti-slip shells 22 are in the storage position, they are flush with the front of the second bed body 12, so that the front of the second bed body 12 is flat, so that the patient can lie down more easily, such as Figure 4As shown, when in the extension position, the openings of both anti-slip plates 30 protrude from the front of the second bed body 12, so that both anti-slip plates 30 can be pushed out of the anti-slip shell 22 and abut against the left and right sides of the patient's chest cavity; two second drive components are respectively located on both sides of the back of the second bed body 12, and can correspond one-to-one with the two anti-slip grooves, and are used to drive the two anti-slip shells 22 to switch back and forth between the storage position and the extension position; wherein, as Figure 6 As shown, both anti-slip components also include a fixing plate 33; the two fixing plates 33 can be respectively mounted on both sides of the back of the second bed 12 via brackets, and correspond one-to-one with the two anti-slip grooves; the two second drive components are respectively mounted on the two fixing plates 33; wherein, as Figure 1 As shown, the second drive assembly includes a second motor 34 and a second screw 35. The second motor 34 can be mounted on the back of the fixed plate 33, and its output shaft passes through the fixed plate 33. The second screw 35 is connected to the output shaft of the second motor 34 and passes through the bottom wall of the anti-slip shell 22, and is threadedly engaged with the bottom wall of the anti-slip shell 22. Of course, the second screw 35 will not interfere with the two first hydraulic cylinders 31. At this time, the anti-slip shell 22 is equivalent to the sliding nut of the second screw 35. The second motor 34 drives the second screw 35 to rotate, and then drives the anti-slip shell 22 to slide along the second screw 35, so that the anti-slip shell 22 switches to the storage position or the protrusion position. Of course, the sliding direction of the anti-slip shell 22 is also the axial direction of the second screw 35, and the anti-slip shell 22 will not rotate with the rotation of the second screw 35 due to the limitation of the anti-slip groove.

[0090] In other words, both anti-slip components can be retracted to be flush with the front of the second bed 12 to restore the flatness of the front of the second bed 12, making it easier for the patient to lie down. Both anti-slip components can also protrude from the front of the second bed 12 so that their two anti-slip plates 30 can be pushed out of the anti-slip shell 22 and abut against the left and right sides of the patient's chest cavity.

[0091] Furthermore, the thoracentesis bed provided in this embodiment of the invention also includes a fixation component, such as... Figure 4 As shown, the fixing components include: two fixing blocks 28, two third drive components, and a fixing belt 29;

[0092] like Figure 2 As shown, the second bed body 12 has fixed through slots 66 on both sides of its front side, and is close to the first bed body 11;

[0093] like Figure 4 As shown, the two fixing blocks 28 are slidably disposed in the two fixing slots 66, and each has a switchable storage position and a protruding position. When the two fixing blocks 28 are in the storage position, they are flush with the front of the second bed 12, and when they are in the protruding position, they protrude from the front of the second bed 12.

[0094] Two third drive components are used to drive the two fixed blocks 28 to switch back and forth between the storage station and the protrusion station.

[0095] like Figure 4 As shown, one end of the fixation strap 29 is fixed to the fixation block 28, and the other end is used to be inserted into another fixation block 28 to fix the patient's abdomen.

[0096] It should be noted that, as Figure 2 As shown, the second bed body 12 has fixing slots 66 on both sides of its front side, and these slots are located near the front end of the second bed body 12, between the first bed body 11 and the two anti-slip slots; Figure 4 As shown, two fixing blocks 28 are slidably disposed within two fixing slots 66; wherein, the sliding direction of the fixing blocks 28 is the normal direction of the front or back of the second bed body 12, that is, perpendicular to the front or back of the second bed body 12, so as to form a switchable storage position and an extension position; wherein,

[0097] Both fixing blocks 28 are flush with the front of the second bed 12 when in the retracted position, ensuring the flatness of the front of the second bed 12 for easy patient lying down. When in the extended position, they protrude from the front of the second bed 12, facilitating the insertion of the other end of the fixing strap 29 into the other fixing block 28 for securing the patient's abdomen. Two third drive components can be respectively located on the back of the second bed 12 and are used to drive the two fixing blocks 28 back and forth between the retracted and extended positions. Figure 4 As shown, the fixation strap 29 can be a binding strap, with one end fixed to the fixation block 28 (such as the left fixation block), and the other end used to insert into another fixation block 28 (such as the right fixation block) to fix the patient's abdomen. This prevents the patient from sliding downwards and also prevents changes in the patient's position, thereby better ensuring the puncture effect; in addition, as Figure 4 As shown, another fixing block 28 may have insertion holes extending through its left and right ends, and the other end of the binding strap may have an insertion strip 40, such as... Figure 12 As shown, the insertion strip 40 of the binding strap can be inserted into the insertion hole of another fixing block 28, and then the fourth locking member 41 (which can be a locking bolt) is tightened to the other fixing block 28 to lock the insertion strip 40 of the binding strap, that is, to limit the sliding of the insertion strip 40; wherein, one end of the binding strap can be tightened to the fixing block 28 by means of thread tightening, and the outside of the binding strap can be wrapped with a sponge pad, and when the binding strap is bound to the patient's abdomen, the tightness of the binding strap can be adjusted according to the patient's weight profile, that is, the binding strap can be adapted to the fixation of the abdomen of patients of different body types.

[0098] Furthermore, such as Figure 2 As shown, both fixed through slots 66 are elongated through slots, and the two fixed blocks 28 can slide horizontally one by one within the two fixed through slots 66.

[0099] like Figure 5 As shown, the fixing assembly also includes: two fixing shells 21 and two translational components;

[0100] Two translation components are respectively located on both sides of the back of the second bed 12, and are parallel to the two fixed through slots 66.

[0101] Two fixed shells 21 are respectively set at the movable ends of the two translation components, and correspond to the two fixed through slots 66.

[0102] The two third drive components are each housed in one of the two fixed housings 21, and their output ends are threaded into the two fixed blocks 28.

[0103] It should be noted that, as Figure 2 As shown, both fixed through slots 66 can be elongated through slots, and both are parallel to the rotation axis of the second bed body 12; the two fixed blocks 28 can also slide horizontally within the two fixed through slots 66; wherein, in this case, the sliding direction of the fixed blocks 28 is parallel to the rotation axis of the second bed body 12, that is, the two fixed blocks 28 can slide towards or away from each other; the two translation components are respectively arranged on both sides of the back of the second bed body 12, and are parallel to the two fixed through slots 66; wherein, as Figure 9 As shown, the translation component can be a linear motor, and can be set on one side of the fixed through slot 66, parallel to the fixed through slot 66; the two fixed housings 21 can be set one by one on the moving ends (i.e., linear motor movers) of the two linear motors, and correspond one-to-one with the two fixed through slots 66, so that the two fixed housings 21 can be driven to slide relative to each other (sliding towards each other and sliding away from each other) by the two linear motors; the two third drive components can be set one by one in the two fixed housings 21, and their output ends are threadedly engaged with the two fixed blocks 28; specifically, as Figure 13As shown, the third drive assembly may include: a drive gear 36, a driven gear 37, a rotating shaft 38, and a third motor 39; the fixed housing 21 may be a box-shaped structure; the first end of the rotating shaft 38 passes through the fixed housing 21 along a first direction and is fitted with the driven gear 37, and the second end passes through the bottom of the fixed block 28 and is threadedly engaged with the bottom of the fixed block 28; the first direction is the normal direction of the back surface of the second bed 12; the third motor 39 is disposed within the fixed housing 21 and is parallel to the rotating shaft 38; the drive gear 36 is fitted onto the output shaft of the third motor 39 and is parallel to the shaft 38. Driven gear 37 engages; wherein, the third motor 39 drives the power gear 36 to rotate, which in turn drives the rotating shaft 38 to rotate. Then, based on the threaded engagement between the second end of the rotating shaft 38 and the bottom of the fixed block 28 (equivalent to the engagement of a lead screw and nut), the fixed block 28 will also slide along the second end of the rotating shaft 38, allowing the fixed block 28 to switch to the storage position or the protrusion position. Of course, due to the limitation of the fixed through slot 66, the fixed block 28 will not rotate with the rotation of the second end of the rotating shaft 38, and the fixed block 28 can be a long strip fixed block; in addition, such as Figure 6 As shown, second pneumatic clamps 24 can be provided on both sides of the back of the second bed 12. Figure 6 (This can be used to illustrate the mounting position of the second pneumatic clamp 24), and is used to limit the sliding of the two fixed shells 21. Of course, the outer side wall of the fixed shell 21 is provided with a limiting groove for engaging with the second pneumatic clamp 24.

[0104] In other words, the above design allows for adjustment of the distance between the two fixing blocks 28 to accommodate the abdominal fixation of patients with different body widths. Furthermore, the third drive component is built into the fixing shell 21, which makes the structure of the fixing component compact and reduces space occupation.

[0105] In this design, the first bed 11 is rotatably mounted on the bed frame in the vertical direction and has a switchable first workstation and a second workstation, such as... Figure 4 As shown, the first bed body 11 is parallel to the bed frame in the first working position and perpendicular to the bed frame in the second working position;

[0106] The bed for thoracentesis also includes a fourth drive assembly, which drives the first bed body 11 to switch back and forth between the first position and the second position.

[0107] like Figure 4 As shown, the middle part of the second bed body 12 has a through back groove 26, and two anti-slip components are located on both sides of the back groove 26.

[0108] like Figure 4 As shown, the bed also includes a back panel 27 that can be detachably installed in the backrest groove 26 of the second bed 12.

[0109] It should be noted that, as Figure 6As shown, the bed frame also includes: two support frames 63 and two sets of connecting rods; wherein, the two support frames 63 are arranged in parallel and distributed between the two second supports 18; each support frame 63 is connected and fixed to the adjacent second support 18 by a set of connecting rods; in addition, as Figure 6 As shown, this hospital bed may further include: a support column 65 and a fixing plate 14; the support column 65 may be disposed between two support frames 63, and the fixing plate 14 may be disposed at the top of the support column 65; the first bed body 11 may be rotatably disposed on the fixing plate 14 in the vertical direction; wherein, as Figure 4 As shown, the first bed 11 is parallel to the bed frame in the first position and perpendicular to the bed frame in the second position, so that the patient can turn so that his / her back faces the medical staff, avoiding the medical staff having to go around to the head of the bed to perform the puncture, thus making it easier for the medical staff to perform thoracentesis; of course, the first position of the first bed 11 is the initial position, and the second position is the puncture position.

[0110] Additionally, the fourth drive assembly is used to drive the first bed 11 to switch back and forth between the first and second workstations; wherein, for example... Figure 7 As shown, the fourth drive assembly may include a fourth motor 20, which may be disposed downwards on the back of the first bed 11 and close to the front end of the first bed 11. The output shaft of the fourth motor 20 may be provided with an arc-shaped rack or gear. The outer peripheral wall of the fixed disk 14 may be provided with teeth for meshing with the arc-shaped rack or gear on the output shaft of the fourth motor 20. When the fourth motor 20 is working, based on the meshing of the arc-shaped rack or gear with the teeth on the outer peripheral wall of the fixed disk 14, the fourth motor 20 can move circumferentially along the fixed disk 14, thereby driving the first bed 11 to rotate. Of course, the fourth motor 20 can rotate in both directions to drive the first bed 11 to switch back and forth between the first and second workstations. Figure 7 As shown, the back of the first bed 11 may be provided with a first pneumatic clamp 54, which is used to hold the fixing plate 14 when the first bed 11 is in the first working position, so as to lock the first bed 11 in the first working position and prevent the first bed 11 from being rotated arbitrarily. Moreover, the first pneumatic clamp 54 can rotate with the first bed 11 to the second working position and can be used to hold the second through slot 53 of the fixing plate 14, so that the first bed 11 can also be locked and fixed in the second working position.

[0111] In addition, such as Figure 4As shown, a square backrest groove 26 can be formed in the middle of the second bed frame 12, located between two anti-slip components, that is, the two anti-slip components are located on the left and right sides of the backrest groove 26 respectively; the back panel 27 can be detachably installed in the backrest groove 26 of the second bed frame 12, and the front of the back panel 27 can be flush with the front of the second bed frame 12 to ensure the flatness of the front of the second bed frame 12; wherein, the thickness of the back panel 27 can be less than the thickness of the second bed frame 12, and multiple spring pins can be provided on the left and right sides of the back of the back panel 27, and the left side of the backrest groove 26... Multiple pin holes can be provided on both the back wall and the right side wall. When the back plate 27 is flush with the back groove 26 of the second bed body 12, multiple spring pins on the left side of its back can be inserted into multiple pin holes on the left side wall of the back groove 26, and multiple spring pins on the right side of its back can be inserted into multiple pin holes on the right side wall of the back groove 26, thereby realizing the installation of the back plate 27 in the back groove 26. Of course, when the patient needs to undergo thoracentesis, the spring pins on the back of the back plate 27 can be slid to remove the back plate 27 so that the patient's back can be exposed.

[0112] Specifically, such as Figure 7 As shown, the middle part of the first bed body 11 has two parallel first through slots 50, which are perpendicular to the rotation axis of the second bed body 12.

[0113] like Figure 4 As shown, the bed also includes two cover plates 51, which are detachably installed in the slots of the two first through slots 50 of the first bed 11.

[0114] It should be noted that, as Figure 7 As shown, the middle portion of the first bed 11 may have two parallel first through slots 50. Both first through slots 50 may be elongated through slots and are perpendicular to the rotation axis of the second bed 12. This allows the first bed 11 to be rotated to the second position for thoracentesis, enabling the patient's feet to be inserted into the lower part of the first bed 11, thus providing a comfortable sitting position. Of course, if... Figure 7 As shown, the edge of the fixed plate 14 has two clearance slots, and when the first bed 11 rotates to the second position, its two first slots 50 can correspond one-to-one with the two clearance slots of the fixed plate 14, so as to prevent the fixed plate 14 from obstructing the insertion of the patient's feet. Figure 5 As shown, foot pedals 17 can be provided on both sides of the second support 18 for the patient to step on with both feet; in addition, as Figure 4As shown, two cover plates 51 are detachably installed in the openings of the two first through slots 50 of the first bed body 11, and are flush with the front of the first bed body 11 to ensure the flatness of the front of the first bed body 11. Of course, by covering the two first through slots 50 of the first bed body 11 with the two cover plates 51, the patient's discomfort with the two first through slots 50 of the first bed body 11 can be eliminated. In addition, the above-mentioned two first through slots 50 can be opened again in the part of the first bed body 11 near its front end, and two more cover plates 51 should be added to cover the openings of the two additional first through slots 50. The cover plate 51 can be a long strip cover plate, and can be slidably pushed into or slidably pulled out of the opening of the first through slot 50.

[0115] Furthermore, such as Figure 6 As shown, the thoracentesis bed provided in this embodiment of the invention further includes: a support column 65, a fixing plate 14, and a fifth drive assembly;

[0116] The support column 65 is rotatably mounted on the bed frame around the first horizontal direction;

[0117] The fixing plate 14 is located at the top of the support column 65;

[0118] The first bed 11 can be rotatably mounted on the fixed plate 14 in the vertical direction;

[0119] The fifth drive assembly is disposed on the bed frame and is used to drive the fixed disk 14 to rotate about a first horizontal direction; wherein the first horizontal direction is parallel to the axis of rotation of the second bed body 12.

[0120] It should be noted that, as Figure 6 As shown, the bed frame also includes a rotating shaft 64, which is arranged between the tops of the two second supports 18 along a first horizontal direction, and passes sequentially through the top of the support frame 63, the lower part of the support column 65, and the top of another support frame 63. The lower part of the support column 65 is fixedly connected to the middle part of the rotating shaft 64, meaning the lower part of the support column 65 can rotate with the rotating shaft 64. Furthermore, as mentioned above, a fixing plate 14 is disposed at the top of the support column 65, and the first bed body 11 can be rotatably mounted on the fixing plate 14 in a vertical direction. Additionally, as... Figure 5 As shown, the bed frame also includes a U-shaped mounting plate 57, which can be horizontally positioned at the front end of the bottom of the two support frames 63. A second sliding groove 56 can be opened on the back of the fixing plate 14, parallel to the first through groove 50 of the first bed body 11; specifically, as... Figure 1 and Figure 5As shown, the fifth drive assembly may include: a sliding block 55 and a second hydraulic cylinder 15; wherein, the sliding block 55 is slidably disposed in the second slide groove 56 on the back of the fixed plate 14, and the sliding block 55 will not fall out of the second slide groove 56; the second hydraulic cylinder 15 is vertically disposed on the mounting bracket 57 and has a second telescopic rod 16, and its movable end is rotatably connected to the bottom of the sliding block 55 (such as hinged); of course, the first bed 11 is normally in a horizontal state, and when it is necessary to adjust the pitch angle of the first bed 11, the second hydraulic cylinder 15 can be used. The second telescopic rod 16 of the first bed extends, thereby causing the fixed plate 14 to rotate or swing around the first horizontal direction, thus realizing the adjustment of the pitch angle of the first bed 11 and the second bed 12. This can also be used to adjust the pitch angle of the patient's sitting posture, thus avoiding the need for medical staff to manually assist and adjust the pitch angle of the patient's sitting posture. Of course, through the above-mentioned pitch angle adjustment, it can adapt to the posture needs of patients with different body characteristics, which facilitates the smooth performance of thoracentesis. In other words, the lower side of the first bed 11 is provided with an adjustment component for adjusting the pitch angle of the first bed 11.

[0121] Furthermore, the thoracentesis bed provided in this embodiment of the invention also includes a support assembly, such as... Figure 4 As shown, it includes: support rod 42, support plate 13 and sixth drive assembly;

[0122] like Figure 4 As shown, a storage groove 44 is provided in the middle part of the front of the first bed body 11 along the second horizontal direction;

[0123] The first end of the support rod 42 is rotatably mounted on one end of the storage slot 44 around a first horizontal direction, and has a switchable storage position and a support position. When in the storage position, the support rod 13 is located within the storage slot 44. Figure 4 As shown, the storage slot 44 protrudes from the support station; wherein, the first horizontal direction is parallel to the rotation axis of the second bed 12 and perpendicular to the second horizontal direction;

[0124] The sixth drive assembly is used to drive the rotation of the first end of the support rod 42, so that the support rod 42 switches back and forth between the storage position and the support position.

[0125] The support plate 13 is used to be detachably installed on the second end of the support rod 42 when the support rod 42 is switched to the support position.

[0126] It should be noted that, as Figure 4 As shown, a storage groove 44 is provided in the middle part of the front of the first bed body 11 along the first horizontal direction (such as the front-to-back direction), and can be located between two first through grooves 50. Of course, the storage groove 44 can be a through storage groove; the bottom end of the support rod 42 can be flipped around the first horizontal direction (such as the left-to-right direction) and set at the rear end of the storage groove 44, and flipped back into the storage groove 44 when in the storage position. Figure 4 As shown, the support rod 42 flips out of the storage slot 44 when in the support position; the flipping angle of the support rod 42 can be greater than 90° and less than 180°, and the support rod 42 needs to have a self-locking function or be able to be locked when in the support position to prevent the support rod 42 from shaking when in the support position; of course, as Figure 4 As shown, the length of the support rod 42 is adjustable, for example, a telescopic support rod can be used, and a tightening assembly (not shown) is provided on the support rod 42 so that the length can be locked after the support rod 42 extends to a fixed length;

[0127] In addition, the sixth drive assembly is used to drive the bottom end of the support rod 42 to rotate, so that the support rod 42 can switch back and forth between the storage position and the support position. Specifically, the sixth drive assembly (not shown in the figure) may include: a motor, a first gear and a second gear. The first gear may be set on one side wall of the bottom end of the support rod 42 and coaxial with the rotating shaft of the bottom end of the support rod 42. The motor may be set on the back of the first bed 11 along the first horizontal direction, and its output shaft is sleeved with the second gear and used to mesh with the first gear at the bottom end of the support rod 42. The motor does not interfere with the fixed plate 14 and the first pneumatic clamp 54. When a thoracentesis is required, the first gear is indirectly driven to rotate by the motor, thereby driving the bottom end of the support rod 42 to rotate around the first horizontal direction. Moreover, this driving method can also make the rotation of the bottom end of the support rod 42 have a self-locking function. Of course, other sixth drive assemblies can also be used in this solution, which will not be described in detail here.

[0128] In addition, such as Figure 4 As shown, when the support rod 42 is switched to the support position, the support plate 13 is detachably installed on the top of the support rod 42 and used to press against the patient's chest and face to stabilize the patient's position and prevent changes in the patient's posture; wherein, the installation angle of the support plate 13 at the top of the support rod 42 can be adjusted and locked so that the support plate 13 can be adapted to press against the patient's chest and face; specifically, as Figure 4 As shown, the bottom of the support plate 13 can be rotatably mounted on the top of the support rod 42 along the first horizontal direction, and can be locked by the locking screw 43, so that the support plate 13 can be locked and fixed when the installation angle is adjusted.

[0129] In this solution, the thoracentesis bed provided in this embodiment of the invention further includes two handrail assemblies, such as... Figure 4 As shown, each includes: a sliding block 23, a rotating rod 48, a handrail 49, a first locking element 47, a second locking element, and a third locking element 52;

[0130] like Figure 7 As shown, first sliding grooves 46 are respectively opened on both sides of the back of the first bed body 11 along the first horizontal direction, and respectively communicate with the left and right ends of the first bed body 11.

[0131] like Figure 6 As shown, the two sliding blocks 23 are slidably disposed in the two first sliding grooves 46 of the first bed body 11, and when the two sliding blocks 23 slide to be flush with the left and right ends of the first bed body 11 respectively, they are locked by the first locking member 47.

[0132] like Figure 4 As shown, the first ends of the two rotating rods 48 are rotatably disposed on the left and right ends of the two sliding blocks 23 around the first horizontal direction, and when the two rotating rods 48 rotate to be located above the side of the first bed 11, they are locked by the second locking member.

[0133] like Figure 4 As shown, the first ends of the two handrails 49 are rotatably mounted on the second ends of the two rotating rods 48 around the second direction, and when the two handrails 49 rotate to be perpendicular to the two rotating rods 48, they are locked by the third locking member 52; wherein, the first horizontal direction is parallel to the axis of rotation of the second bed 12 and perpendicular to the second direction.

[0134] It should be noted that, as Figure 7 As shown, the left and right sides of the back of the first bed body 11 are provided with first sliding grooves 46 along the first horizontal direction, and are respectively connected to the left and right ends of the first bed body 11, and are close to the rear end of the first bed body 11. Of course, the two first sliding grooves 46 are respectively equivalent to the left bottom groove and the right bottom groove of the first bed body 11.

[0135] like Figure 6 As shown, two sliding blocks 23 are slidably disposed in the two first sliding grooves 46 of the first bed body 11, and each has a switchable storage position and a flush position; wherein, in the storage position, the two sliding blocks 23 are located inside the left and right ends of the first bed body 11, respectively, and in the flush position, they are flush with the left and right ends of the first bed body 11, respectively. When the two sliding blocks 23 are slid to be flush with the left and right ends of the first bed body 11, respectively, each sliding block 23 can be locked to the back of the first bed body 11 by the first locking member 47; wherein, the sliding block 23 can be an inverted T-shaped structure, and its vertical part is slidably disposed in the first sliding groove 46. In order to prevent the sliding block 23 from detaching, the first sliding groove 46 can adopt a dovetail groove structure, and the first locking member 47 can be a first locking bolt, which is used to tighten the horizontal part of the sliding block 23 to the back of the first bed body 11;

[0136] like Figure 4As shown, the first ends of the two rotating rods 48 are rotatably mounted on the left and right ends of the two sliding blocks 23 around a first horizontal direction, and each has a switchable storage position and a lifting position. When in the storage position, the two rotating rods 48 are parallel to and at the same height as the two sliding blocks 23. When in the lifting position, they are located above the side of the first bed 11. When both rotating rods 48 rotate to their positions above the side of the first bed 11, the first ends of both rotating rods 48 can be locked by the second locking member, thus locking and fixing the two rotating rods 48 after lifting. The first horizontal direction is parallel to the axis of rotation of the second bed 12. Additionally, as... Figure 4 As shown, both rotating rods 48 can be telescopic rotating rods;

[0137] like Figure 4 As shown, the first ends of the two handrails 49 are rotatably mounted on the second ends of the two rotating rods 48 in the second direction, and each handrail has a switchable first position and a second position. In the first position, the two handrails 49 are parallel to the two rotating rods 48, and in the second position, they are perpendicular to the two rotating rods 48, allowing the patient's hands to grip both handrails 49. When the two handrails 49 rotate to be perpendicular to the two rotating rods 48, the first ends of both handrails 49 are locked by a third locking element 52, preventing further rotation. The first horizontal direction and the second direction are spatially perpendicular. The third locking element 52 can be a third locking bolt.

[0138] Furthermore, when both handrail components are in the retracted state, the two sliding blocks 23 slide to the retracted position one by one, the first ends of the two rotating rods 48 rotate to the retracted position, and the first ends of the two handrail bars 49 rotate to the first position. In this way, the two handrail components can be retracted to the sides below the back of the first bed 11. In addition, when both handrail components are in the extended state, the two sliding blocks 23 slide to the flush position one by one, the first ends of the two rotating rods 48 rotate to the raised position, and the first ends of the two handrail bars 49 rotate to the second position. In this way, the two handrail bars 49 can be raised to the top of the sides of the first bed 11 so that the patient can grasp the two handrail bars 49 with both hands.

[0139] In other words, when not in use, the two armrest components can be stored on both sides below the back of the first bed 11, reducing space occupation; when in use, the two armrest components can extend above the sides of the first bed 11 for the patient to hold, increasing the patient's sense of security.

[0140] In addition, it should be noted that the usage method of this hospital bed is as follows:

[0141] In the initial state, the second bed body 12 is horizontal and flush with the first bed body 11. The second bed body 12 can be placed on the first support 10, which provides support. The second bed body 12 and the first bed body 11 form a bed board, and its length direction is the same as the length direction of the bed frame formed by the first support 10, the third support 19, and the second support 18. The back panel 27 is installed on the second bed body 12. The top surface of the anti-slip shell 22 is flush with the top surface of the second bed body 12. The armrest assembly is stored at the bottom of the first bed body 11. The top surface of the fixing block 28 is flush with the top surface of the second bed body 12. The cover plate 51 is inserted into the first through groove, and the support rod 42 is stored in the storage groove 44.

[0142] The medical staff placed the patient lying flat on the second bed 12 and the first bed 11, with the upper body on the second bed 12 and the lower body on the first bed 11;

[0143] When thoracentesis is required, the second motor 34 operates, causing the second screw 35 to rotate, which in turn causes the anti-slip shell 22 to slide upward. Then, the first hydraulic cylinder 31 operates, and the first telescopic rod 32 extends, pushing out the anti-slip plate 30 until the soft pad of the anti-slip plate 30 abuts against both sides of the patient's upper chest cavity.

[0144] Then, the fixing block 28 is pulled up, the third motor 39 is controlled to work, the power gear 36 drives the driven gear 37 to rotate, and the rotating shaft 38 rotates, and then the fixing block 28 slides along the second end of the rotating shaft 38; in addition, by controlling the linear motor to work, the fixing shell 21 slides, the distance between the two fixing blocks 28 is adjusted, and then the second pneumatic clamp 24 is controlled to work, so that the fixing shell 21 is locked and fixed. Then the binding strap is installed on one of the fixing blocks 28; in this embodiment, one end of the binding strap is installed in one fixing block 28, and the insert 40 at the other end is slidably inserted into the other fixing block 28. The tightness of the binding on the patient's abdomen is adjusted, and then the fourth locking member 41 is tightened.

[0145] Next, the first motor 59 is controlled to work, driving the first screw 25 to rotate, which in turn causes the threaded block 60 to slide, which in turn causes the swing arm 62 to pull the hinge plate 58 to rotate, which in turn causes the second bed body 12 to rotate, thereby assisting the patient to sit up.

[0146] Then control the motor to work, so that the first gear rotates, which in turn makes the support rod 42 rotate. The support rod 42 rotates and stands up. Then the support plate 13 is installed on the top of the support rod 42. Adjust the angle of the support plate 13, then insert the locking screw 43 and tighten it. At the same time, the length of the support rod 42 can be adjusted. Control the tightening component to lock the length of the support rod 42. Then pull out the handrail assembly and adjust it to the appropriate position.

[0147] At this time, the fourth motor 20 is controlled to work, so that the first bed 11 rotates around the fixed plate 14 as the rotation center. After rotating ninety degrees, the first pneumatic clamp 54 works to fix the first bed 11 on the fixed plate 14. At this time, the first through slot 50 and the second through slot 53 coincide. Then the rectangular cover is pulled out, and the patient's legs are placed under the first bed 11 through the first through slot 50 and stepped on the foot pedal 17. Then the second bed 12 is controlled to continue to rotate, and the patient's chest and face rest on the support plate 13, and the hands hold the handrail 49.

[0148] Then the backplate 27 is removed, exposing the patient's back. Medical staff hold the ultrasound-guided device to locate the thoracentesis. After positioning, the thoracentesis is performed. If the patient's position needs to be slightly adjusted during the thoracentesis, the second hydraulic cylinder 15 can be controlled to extend or retract the second telescopic rod 16, thereby controlling the sliding block 55 to lift the fixed plate 14 upward or pull the fixed plate 14 downward, so that the fixed plate 14 swings around the rotation axis 64 to adjust the position and angle, making it convenient for medical staff to perform ultrasound-guided puncture.

[0149] In summary, the second bed can be flipped upwards to assist the patient in sitting up. When sitting, the anti-slip shell extends and locks onto both sides of the patient's chest cavity to prevent lateral slippage when sitting up. Furthermore, the binding straps can be adjusted in tightness according to the patient's weight and profile when binding the abdomen. The armrest assembly can be stored under the first bed when not in use, reducing space occupation. A first through-slot is provided on the first bed, allowing the bed to be switched between a bed and a seat. When ultrasound-guided thoracentesis is required, the cover can be pulled out, allowing the patient's legs to extend under the first bed, thus facilitating the patient's movement. The patient can sit up, and with the removal of the backrest, the function of thoracentesis can be switched between lying down and sitting up. The first bed can rotate around the vertical direction so that the patient's back faces the medical staff, making it easier for the medical staff to perform thoracentesis. The support rod can be stored, and the support plate can be adjusted in angle and used to support the patient's chest and face to stabilize the patient's position. Moreover, the angle adjustment can accommodate the needs of patients with different body characteristics. At the same time, during ultrasound-guided positioning and puncture, the tilt angle of the first bed can be adjusted without the need for medical staff to manually support and adjust it, so as to ensure the smooth performance of thoracentesis.
