Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a posture auxiliary support device for thoracentesis treatment of pleural effusion. Background Art

[0002] Thoracentesis treatment is a diagnostic and therapeutic operation that involves inserting a puncture needle into the chest cavity to extract effusion. It is commonly used to clarify the nature of pleural effusion or relieve the compressive symptoms caused by the effusion. Laboratory tests can be performed on the extracted effusion to determine its nature and identify the cause. At the same time, a large amount of effusion can be extracted to relieve compressive symptoms such as chest tightness, shortness of breath, and dyspnea.

[0003] During the operation, the patient needs to lie face down on a chair with their back against the chair back, place both forearms on the chair back, and rest their forehead on their forearms. However, the chairs currently used in hospitals do not have an adjustment function. Patients with different body postures have different heights. When some patients with a relatively high height lie face down on the chair with their back against the chair back, since the height of the chair back is lower than the horizontal height of the patient's arms, it will cause the patient's arms to be unable to maintain a stable lying-down posture when placed, and it will also cause the forehead of their head to be unable to lie on their forearms normally. Therefore, it will cause difficulties for the patient to lie face down, and even cause soreness and limb tremors due to the arms and head not being properly supported for a long time, which will affect the thoracentesis treatment.

[0015] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0016] First, when the patient sits in a prone position, this patent application can keep the patient's torso in an upright state. Under the action of gravity, pleural effusion will accumulate in the lower part of the chest cavity, especially under the back. This enables medical staff to more easily and accurately determine the location and scope of the effusion through methods such as percussion and ultrasound, thereby finding a suitable puncture point, increasing the success rate of puncture, and reducing the risk of accidentally puncturing other tissues or organs.

[0017] At the same time, the structure of the chest cavity in the sitting position is relatively conducive to the natural outflow of effusion. After the puncture needle enters the chest cavity, the effusion is more likely to flow out along the puncture needle and drainage tube under the action of gravity, facilitating the full drainage of the pleural effusion in the chest cavity, reducing the pressure in the chest cavity, and alleviating symptoms such as dyspnea caused by excessive pleural effusion in the patient.

[0018] Second, when the patient lies prone on the table board, the angle of the table board can be adjusted according to the adaptable angle of the patient's neck that can be bent forward. After the angle of the table board is adjusted, a fixed locking state can be formed between the first adjustment plate and the second adjustment plate through bolts, enabling the table board to hover at a fixed position after completing the specified angle adjustment on the second support plate, so that the table board can be adapted to the forward bending angle of the patient's neck for the patient's arms and head to lie prone.

[0019] Third, in order to maintain the balance of the entire auxiliary support device to prevent the patient from tipping backward towards the backrest, a backing plate is provided on the outside of the support plate. The output end of the second electric push rod extends forward to push the push block, connecting rod, and connecting bar towards the backing plate, causing the guide rod on the connecting bar to move along the guide groove on the guide plate, so that the backing plate extends and descends towards the backside area of the backrest, and forms a support on the ground in the backside area of the backrest. When the patient lies prone facing the backrest, the backing plate will form a supporting effect on the rear bottom of the entire auxiliary support device, preventing the entire auxiliary support device from tipping backward, thereby avoiding the tilting displacement of the patient's torso.

[0038] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the scope of protection of the present invention.

[0039] The technical solutions provided by each embodiment of the present invention will be described in detail below in conjunction with the drawings.

[0040] An embodiment of the present invention provides a body position auxiliary support device for thoracentesis treatment, including a sitting part 1 and a backrest part 2; the sitting part 1 is placed flat on a horizontal plane; the backrest part 2 is arranged obliquely on one side of the sitting part 1, and the bottom of the backrest part 2 is fixedly connected to the sitting part 1; a support part 3 for the patient's arm to lie on is arranged at the top of the backrest part 2; a support base 4 with adjustable height is arranged at the bottom of the sitting part 1;

[0041] The sitting part 1 allows the patient to sit, and the backrest part 2 allows the patient to rely on the back for regular sitting to perform preoperative preparation and examination work;

[0042] Before thoracentesis, adjust the support height of the support base 4 according to the patient's height. Then the patient needs to sit facing the backrest part 2, lie the arm on the support part 3, and the abdomen can be attached to the backrest part 2 or not in contact with the backrest part 2. And lower the height of the backrest part 2 and the support part 3 so that the patient can arch the back when lying on the support part 3, so as to facilitate the medical staff to perform thoracentesis treatment operations;

[0043] Among them, when the patient sits in a prone state, the present patent application can keep the trunk of the patient in an upright state. Under the action of gravity, the pleural effusion will accumulate in the lower part of the chest cavity, especially below the back. This enables the medical staff to more easily and accurately determine the location and scope of the effusion through means such as percussion and ultrasound, so as to find a suitable puncture point, improve the success rate of puncture, and reduce the risk of accidentally puncturing other tissues or organs;

[0044] Meanwhile, the structure of the chest cavity in the sitting position is relatively conducive to the natural outflow of the effusion. After the puncture needle enters the chest cavity, the effusion is more likely to flow out along the puncture needle and the drainage tube under the action of gravity, so as to fully drain the effusion in the chest cavity, reduce the pressure in the chest cavity, and relieve symptoms such as dyspnea caused by excessive pleural effusion in the patient. Secondly, when sitting upright, the patient's chest can expand and contract relatively freely, which is conducive to respiratory movement. Compared with the lying position, the sitting position can reduce the restriction on breathing, make the patient breathe more smoothly during the puncture process, reduce the impact of the puncture operation on the respiratory function, and reduce the discomfort and the risk of dyspnea of the patient. Moreover, when the patient is in the sitting position, the positions of the internal organs in the chest cavity are relatively stable, and the doctor can also better avoid important blood vessels and organs during the operation, reducing the possibility of puncture injury, and is also conducive to timely detection and treatment of complications such as a small amount of pneumothorax that may occur during the puncture process. Because if pneumothorax occurs when the patient is in the sitting position, the gas is more likely to gather upward at the top of the chest cavity, which is convenient for timely detection through chest fluoroscopy or other examinations, and the impact of a small amount of pneumothorax on the respiratory function is relatively small in the sitting position.

[0045] In a further preferred embodiment, the riding part 1 includes a riding board 11 and a cushion 12 for the patient to sit on; the riding board 11 is arranged horizontally on the horizontal plane; the cushion 12 is arranged on the riding board 11, and a fixed connection is formed between the cushion 12 and the riding board 11 through a support frame 13; the riding board 11 and the cushion 12 are in the shape of rectangular blocks, and cutouts are provided at two diagonal positions on the side of the riding board 11 and the cushion 12 close to the backrest 2, so that two diagonal positions on the side of the riding board 11 and the cushion 12 close to the backrest 2 are designed to be concave.

[0046] The design that two diagonal positions on the side of the riding board 11 and the cushion 12 close to the backrest 2 are concave allows the patient's legs to be placed in the concave parts when facing the backrest 2, so as to avoid the diagonal parts of the rectangular block shape from hindering the placement of the patient's legs, which may otherwise cause the patient's legs to be placed flat only, affecting the balance of the patient when sitting upright and causing the trunk part to shake or tilt, thus preventing the medical staff from performing puncture treatment normally.

[0047] In a further preferred embodiment, the backrest 2 includes a first support plate 21 and a second support plate 22. Both the first support plate 21 and the second support plate 22 are inclined, and a connection is formed between the first support plate 21 and the second support plate 22 through a telescopically adjustable telescopic rod 23. Soft pads made of flexible materials are fixedly arranged on the surfaces of the first support plate 21 and the second support plate 22 facing the riding board 11.

[0048] The first support plate 21 can be relied on by the patient's waist and abdomen when sitting with the back facing the backrest 2, while the second support plate 22 can be relied on by the patient's back in this sitting posture.

[0049] When the patient sits facing the backrest 2, the second support plate 22 can be relied on by the patient's chest area. At the same time, according to the different heights of the patients, their trunk lengths are also different. The telescopic lengths of multiple telescopic rods 23 can be adjusted to adapt and adjust the height of the second support plate 22 on the first support plate 21.

[0050] In a further preferred embodiment, the support portion 3 includes a table plate 31. The table plate 31 is horizontally arranged at the top end of the second support plate 22, and the table plate 31 is rotatably connected to the top edge portion of the second support plate 22. An adjusting assembly for adjusting the angle of the table plate 31 is provided between the second support plate 22 and the table plate 31;

[0051] The adjusting assembly includes a first adjusting plate 32 and a second adjusting plate 33; both the first adjusting plate 32 and the second adjusting plate 33 are arc-shaped designs; the first adjusting plate 32 is arranged at the bottom of the table plate 31, one end of the first adjusting plate 32 is fixedly connected to the bottom of the table plate 31, and the other end is arranged towards the direction of the second support plate 22; the second adjusting plate 33 is arranged in an overlapping manner with the first adjusting plate 32, that is, the second adjusting plate 33 is located on one side of the first adjusting plate 32; one end of the second adjusting plate 33 is fixedly connected to the rear side of the second support plate 22, and the other end is towards the bottom direction of the table plate 31, so that the second adjusting plate 33 and the first adjusting plate 32 overlap with each other with the rotation connection between the table plate 31 and the second support plate 22 as the axis; a plurality of through holes 331 are arranged around the rotation connection between the table plate 31 and the second support plate 22 on the second adjusting plate 33, and a hand-tightening bolt 34 is arranged on the first adjusting plate 32. The threaded end of the bolt 34 can be inserted into a corresponding through hole 331 after passing through the first adjusting plate 32. Threads adapted to the threaded end on the bolt 34 are arranged at the portion of the first adjusting plate 32 through which the bolt 34 passes and in each through hole 331;

[0052] When the patient lies prone on the table plate 31, the angle of the table plate 31 can be adjusted according to the adaptable angle of the patient's neck and head that can be bent forward. During the adjustment, the first adjusting plate 32 will move on the second adjusting plate 33 following the angle adjustment of the table plate 31. When the angle adjustment of the table plate 31 is completed, the bolt 34 portion on the first adjusting plate 32 will correspond to one of the through hole 331 portions on the second adjusting plate 33. At this time, the bolt 34 can be rotated so that the threaded end at the front end of the bolt 34 is gradually screwed into the corresponding threaded through hole 331 on the second adjusting plate 33 in a thread-mating state, so as to form a fixed locking state between the first adjusting plate 32 and the second adjusting plate 33 through the bolt 34, and make the table plate 31 hover at a fixed position after completing the specified angle adjustment on the second support plate 22, so that the table plate 31 can be adapted to the forward bending angle of the patient's neck for the patient's arms and head to lie prone;

[0053] When the patient's arm and head lie prone on the table board 31, the telescopic rod 23 can be adjusted in terms of its telescopic length according to the length of the patient's torso. When the height of the table board 31 and the second support board 22 is reduced, since the height at which the patient's arm and head lie prone decreases, the trunk of the patient will naturally bend, and it will be exposed to the medical staff in a state where the back arches, so that the position corresponding to the thoracentesis of the pleural effusion on the back can be fully exposed, thereby facilitating the puncture treatment.

[0054] In a further preferred embodiment, the support base 4 includes a bottom plate 41; the bottom plate 41 is in the shape of a rectangular block, and universal wheels 42 with locking functions are arranged at the four diagonal positions corresponding to the bottom of the bottom plate 41; two groups of elevation parts are symmetrically arranged between the bottom plate 41 and the seat board 11; the elevation part is composed of two adjusting rods 43, and the two adjusting rods 43 are arranged in a cross state, the cross part between the two adjusting rods 43 is rotatably connected, and the ends of the two adjusting rods 43 facing the backrest 2 are respectively rotatably connected to the bottom plate 41 and the seat board 11; the other ends of the two adjusting rods 43 are respectively provided with sliders 44, the sliders 44 are rotatably connected to the two adjusting rods 43, and the sliders 44 connected to the two adjusting rods 43 can respectively perform translational sliding on the corresponding bottom plate 41 and seat board 11; a first electric push rod 45 is arranged between the two groups of cross - arranged adjusting rods 43 on the bottom plate 41, the first electric push rod 45 is fixedly installed on the bottom plate 41 in a horizontal state, and the output end of the first electric push rod 45 is fixedly connected to the slider 44 close to the bottom plate 41 direction;

[0055] The first electric push rod 45 in this patent application is configured with a matching controller;

[0056] According to the different heights of patients, the output end of the first electric push rod 45 can be extended forward or backward by operating the controller. When the output end of the first electric push rod 45 extends forward, it will push the slider 44 close to the bottom plate 41 part to translate outward in the direction of the bottom plate 41, and drive the corresponding adjusting rod 43 to pull outward in the direction of the bottom plate 41. Since the cross part between the two adjusting rods 43 is rotatably connected, therefore, when one of the adjusting rods 43 is pulled by the slider 44 in the direction of the bottom plate 41, it will drive the other adjusting rod 43 to close together with the cross - rotation connection part as the axis. At the same time, the slider 44 on the other adjusting rod 43 will also translate outward at the bottom of the seat board 11 due to the angle adjustment of the corresponding adjusting rod 43, so that the support height at both ends of the two adjusting rods 43 decreases, thereby realizing the height reduction adjustment of the entire seat part 1;

[0057] When the output end of the first electric push rod 45 retracts backward, it will drive the corresponding slider 44 on the bottom plate 41 to translate in the direction of the first electric push rod 45, and cause the corresponding adjusting rod 43 to tilt and contract inward. In this way, it can be realized to control the two ends of the two adjusting rods 43 facing the bottom plate 41 and the riding plate 11 to gradually approach, so as to raise the support height of the upper and lower ends of the two adjusting rods 43, and thus the height of the entire riding part 1 can be adjusted to be raised.

[0058] In a further preferred embodiment, a support plate 5 is provided at the bottom of the bottom plate 41. The two sides of the support plate 5 are bent and extended upward and are fixedly connected to the bottom of the bottom plate 41; a cushion plate 51 that can support the ground is provided on the outer side of the support plate 5 facing the backrest 2; a connecting rod 52 is provided on the cushion plate 51. The front end of the connecting rod 52 is fixedly connected above the cushion plate 51, and the end of the connecting rod 52 extends to the upper area of the support plate 5; a pushing block 53 that can slide horizontally on the support plate 5 is provided at the end of the connecting rod 52. An inclined connecting rod 54 is provided between the pushing block 53 and the end of the connecting rod 52. One end of the connecting rod 54 is rotatably connected to the end of the connecting rod 52 and the other end is rotatably connected to the top of the pushing block 53; a second electric push rod 55 is provided at the end of the pushing block 53. The second electric push rod 55 is fixedly installed on the support plate 5, and the output end of the second electric push rod 55 is fixedly connected to the end of the pushing block 53; a guiding slider 56 is provided on one side of the support plate 5 at the end of the connecting rod 52. The guiding slider 56 can slide horizontally on the support plate 5 and has the same horizontal sliding direction as the pushing block 53. The end of the connecting rod 52 is in vertical sliding fit with the guiding slider 56; a guiding plate 57 is fixedly provided on the other side of the support plate 5 at the end of the connecting rod 52. A guiding groove 58 is provided on the guiding plate 57. The guiding groove 58 is arranged horizontally, and one end of the guiding groove 58 facing the cushion plate 51 is bent and extended downward; a guiding rod 59 is fixedly provided on one side of the end of the connecting rod 52 facing the guiding plate 57. The guiding rod 59 penetrates into the guiding groove 58 on the guiding plate 57 and can move along the track of the guiding groove 58 in the guiding groove 58;

[0059] The second electric push rod 55 in this patent application is configured with a matching controller;

[0060] When the patient lies prone and sits facing the backrest 2, the center of gravity of the arms, head and torso is transferred to the rear area of ​​the backrest 2. Therefore, in order to maintain the balance of the entire auxiliary support device to prevent the patient from tipping over to the rear of the backrest 2, a pad 51 is provided on the outer side of the support plate 5. During operation, the output end of the second electric push rod 55 can be driven forward by operating the controller, and the push block 53 can be pushed in the direction of the pad 51. When the push block 53 moves forward, the connecting rod 54 can be driven to adjust downward. When the connecting rod 54 is at the maximum tilt angle, it will drive the connecting rod 52 and the guide slider 56 to move in the support plate 5. When the connecting rod 52 is moved forward on the support plate 57, as the connecting rod 52 extends forward and moves horizontally, the guide rod 59 on the connecting rod 52 will move along the guide groove 58 on the guide plate 57. When the guide rod 59 moves from the horizontal position in the guide groove 58 to the downward bending extension position, the guide rod 59 will drive the entire connecting rod 52 to slightly drop to a certain height. When the connecting rod 52 drops, the guide slider 56 and the end of the connecting rod 52 slide up and down to guide the moving direction of the connecting rod 52. Since the guide slider 56 and the support plate 5 are in a translational sliding cooperation, the connecting rod 52 can only move in a cross direction of translation and lifting.

[0061] When the guide rod 59 at the end of the connecting rod 52 moves in the transverse position of the guide groove 58, the front end of the connecting rod 52 will drive the pad 51 to extend toward the rear side of the backrest 2. When the guide rod 59 at the end of the connecting rod 52 moves from the transverse position in the guide groove 58 to the downward bending extension position, the connecting rod 52 will drive the pad 51 to descend, and cause the bottom of the pad 51 to fit the ground to be in the same horizontal plane with the multiple universal wheels 42 at the bottom of the bottom plate 41. At this time, the pad 51 will form a support on the ground in the rear area of ​​the backrest 2. When the patient lies down facing the backrest 2, the pad 51 will support the rear bottom of the entire auxiliary support device, so that the entire auxiliary support device will not fall backwards, thereby preventing the patient's torso from falling and displacement.

[0062] When the pleural effusion puncture treatment is completed and the entire device needs to be moved, the output end of the second electric push rod 55 can be driven to retract backward by operating the controller, and the push block 53 can be pulled, so that the connecting rod 54 is gradually adjusted to the horizontal direction and the connecting rod 52 is pulled. As the connecting rod 52 moves backward, the guide rod 59 will gradually retreat to the horizontal position at the bent downward extension part of the guide groove 58. At this time, the connecting rod 52 will also drive the pad 51 to rise and retreat in the direction of the support plate 5, so that the pad 51 is separated from the ground and stops contacting the ground. At this time, because there is no resistance, the entire device can be moved after unlocking the universal wheel 42.

[0063] In a further preferred embodiment, an arm support member 6 for placing a patient's arm is provided at the rear side of the first support plate 21; the arm support member 6 is composed of two arm support plates 61, and the two arm support plates 61 are arranged in the same inclined direction as the first support plate 21. The tops of the two arm support plates 61 are bent and extend horizontally towards the rear side of the first support plate 21; a grip bar 62 for the patient to hold is fixedly arranged at the top ends of the two arm support plates 61 after being bent and placed horizontally; a cross plate 63 is arranged between the two arm support plates 61, and both ends of the cross plate 63 are fixedly connected to the two arm support plates 61 respectively; a sliding groove 131 for placing the cross plate 63 and performing inclined up-and-down movement is provided on the support frame 13; a plurality of through holes 331 are arranged vertically on the cross plate 63, and a hand-tightenable bolt 34 is provided at the position of the sliding groove 131 on the support frame 13. The threaded end of the bolt 34 passes through the support frame 13 and can be inserted into a corresponding through hole 331 on the cross plate 63. Threads adapted to the threaded end of the bolt 34 are provided at the position on the support frame 13 through which the bolt 34 passes and in each through hole 331 on the cross plate 63; stoppers 64 are arranged on both sides of the support frame 13 on the cross plate 63, and the stoppers 64 are fixedly connected to the cross plate 63.

[0064] When the patient maintains a prone sitting position for a certain period of time, when crossing the arms and placing the head, discomfort will be felt. Therefore, the arm support member 6 is provided in this patent application. During use, the height of the cross plate 63 can be adjusted according to the height required for placing the patient's arm. During adjustment, the stoppers 64 on both sides of the support frame 13 on the cross plate 63 can slide on both sides of the sliding groove 131 of the support frame 13 following the lifting and lowering of the cross plate 63, so as to limit the cross plate 63 and prevent the cross plate 63 from tilting during lifting and lowering movement.

[0065] After completing the height adjustment of the cross plate 63, the bolt 34 can be rotated to make the threaded end of the bolt 34 penetrate into the corresponding threaded through hole 331 on the cross plate 63, and the bolt 34 is used to limit the cross plate 63 and the sliding groove 131 part of the support frame 13, so that the cross plate 63 and the two arm support plates 61 can achieve the locking and hovering function after the height adjustment is completed.

[0066] The horizontally placed parts after bending on the two arm support plates 61 can be used for the patient's arms to rest. The patient can lean the arms on the two arm support plates 61 and hold the hands on the grip rod 62 to give the arms a certain holding control force, so as to maintain the balance of the patient's entire torso. At the same time, when the horizontally placed bent parts on the two hand support plates form a support from the bottom of the patient's arms, the patient can press down on the arms to maintain torso stability. Subsequently, the patient can lie prone on the table board 31 normally. In this way, there is no need to cross the arms and lie prone on the table board 31 and then place the head on the arms, which can effectively avoid the oppressive discomfort of the head on the arms and the discomfort caused by the tendon tissues in the patient's axillary tendon and scapular region being stretched for a long time when the arms are crossed for a long time. By setting the arm support member 6, more arm placement space can be provided for the patient, enabling the patient to lie prone and sit in a more comfortable manner and adapting to the torso characteristics to cooperate with medical staff for thoracentesis treatment.
