Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of medical devices, and particularly relates to an anesthesia auxiliary device and system. BACKGROUND
[0002] In clinical anesthesia practice, intraspinal anesthesia is a common anesthesia method in surgical operation, and its successful implementation highly depends on the stability of the patient's body position. The patient needs to maintain a standard knee chest lateral position, that is, the knees are bent close to the chest, the head is bent forward, and the back is arched, so as to fully expose the spinal space and provide a clear operation mark for puncture operation.
[0003] However, this body position requires high body control and endurance of the patient. Before anesthesia, the patient often has limited limb movement due to tension, pain or underlying diseases, and it is difficult for the patient to maintain the standard posture for a long time. At this time, the conventional clinical practice is to continuously assist and fix the patient's body position by the nurse: the nurse needs to hold the patient's shoulders, legs or hips with hands, and constantly adjust the patient's body posture to ensure that it meets the puncture requirements.
[0004] This continuous assistance mode requires the nurse to stay by the patient's side throughout the operation, which cannot be interrupted to complete other nursing work (such as preparing anesthesia equipment, monitoring patient vital signs, etc.), greatly increasing the workload of the nurse, especially during the peak operation period, which may cause tension in human resource allocation. On the other hand, the nurse needs to maintain a fixed posture such as bending over for a long time, which may cause muscle strain. In addition, the stability of human assistance is limited, and if the nurse relaxes slightly or the patient moves slightly due to discomfort, the body position may deviate, affecting the puncture accuracy, and even the body position needs to be adjusted again, prolonging the anesthesia operation time and increasing the patient's pain and anxiety.
[0005] Therefore, there is an urgent need in the clinic for an instrument that can replace the continuous assistance of the nurse to help the patient stably maintain the knee chest lateral position, so as to reduce the burden of medical staff and improve the efficiency and safety of anesthesia operation.
[0006] The methods described in this section are not necessarily the methods that have been previously conceived or employed. Unless otherwise indicated, nothing in this section should be construed as a limitation on any method described herein solely based on its inclusion in this section. Similarly, issues mentioned in this section should not be assumed as having been admitted in any prior art unless otherwise indicated. SUMMARY
[0007] The purpose of the present application is to overcome the deficiencies in the prior art and provide an anesthesia auxiliary device and anesthesia auxiliary system to solve the problem that the patient is difficult to maintain the knee chest lateral position independently during intraspinal anesthesia and the continuous assistance of the nurse leads to an increase in workload and an increase in operation risk.
[0008] To achieve the above-mentioned purpose, one technical scheme adopted by the present application is: An anesthesia auxiliary device, comprising: Two slide rails, each provided with a plurality of locking grooves on the upper side along the length direction; A restraint assembly, comprising: Two slide assemblies, each for slidingly assembling with a slide rail, comprising: A first slide, provided with a first sliding groove for slidingly assembling with the slide rail, and provided with a second sliding groove at the upper end and communicated with the first sliding groove; A second slide, slidingly assembled in the second sliding groove, provided with a first guide surface inclined from top to bottom and a second guide surface inclined from bottom to top on the lower end, and provided with an insertion groove at the upper end and penetrating the second guide surface; An insertion piece, inserted in the insertion groove; A limiting piece, provided on the upper end of the insertion piece, for abutting against the upper end of the second slide, and when abutting, the lower end of the insertion piece is not below the lower end of the second slide, and the height difference between the two ends is less than the depth of the insertion groove; A flexible restraint piece, connected with the insertion pieces of the two slide assemblies at the opposite ends.
[0009] Further, the upper end of the first slide and the upper end of the second slide are both extended to the side of the insertion piece to connect the flexible restraint piece, and the side of the first slide and the side of the second slide are respectively provided with a first clearance groove and a second clearance groove matched with the flexible restraint piece.
[0010] Further, the side of the second slide is provided with a rotation-stopping part extended into the second clearance groove, and the rotation-stopping part cooperates with the second clearance groove to limit the axial rotation of the second slide in the second sliding groove.
[0011] Further, the inner side of the first sliding groove is provided with a first rotation-stopping surface, and the upper end of the slide rail is provided with a second rotation-stopping surface matched with the first rotation-stopping surface, and the first rotation-stopping surface cooperates with the second rotation-stopping surface to limit the axial rotation of the first slide outside the slide rail.
[0012] Further, the longitudinal middle part of each end of the flexible restraint piece is provided with a handle groove.
[0013] Further, the limiting piece is upwardly extended to form a handle.
[0014] Further, the flexible restraint piece is in the shape of a cloth piece.
[0015] Further, when the limiting piece abuts against the upper end of the second slide, the lower end of the insertion piece is flush with the lower end of the second slide.
[0016] Further, the lower end of the plug-in part has a circular truncated cone part with a wide lower end and a narrow upper end, and the locking groove corresponds to the side surface of the plug-in part, and the included angle between the side surface and the bottom surface is less than 90 degrees.
[0017] The anesthetic auxiliary system comprises the anesthetic auxiliary device and a medical device, and the anesthetic auxiliary device is connected with the medical device through the slide rail.
[0018] Compared with the prior art, the anesthetic auxiliary device and the anesthetic auxiliary system have the following advantages: The anesthetic auxiliary device can replace manual assistance and greatly reduce the workload of medical staff. Through the cooperative design of the double slide rails and the double constraint components, the patient's shoulder and hip can be stably constrained, the effect of the nurse's double-hand holding can be simulated, the working mode that the nurse needs to be near the patient and continuously adjust the body position in the clinic can be replaced, and the medical staff can focus on the anesthesia puncture operation, instrument preparation and patient vital sign monitoring, so that the human resource tension problem can be effectively relieved, and the muscle strain of the nurse caused by long-time bending and holding can be avoided.
[0019] The locking structure is stable and reliable, and the body position accuracy is guaranteed. In the sliding component, the circular truncated cone part at the lower end of the plug-in part and the inclined surface of the inner wall of the locking groove form a wedge-shaped cooperation. When the patient generates a backward reaction force due to the maintenance of the curled position, the wedge-shaped structure will be further locked, so that the constraint component is prevented from loosening and deviating. This design ensures the stability of the body position from the mechanical structure level, reduces the deviation of the puncture site caused by the slight movement of the patient or the failure of the constraint, reduces the anesthesia operation rework rate, improves the puncture success rate, and reduces the discomfort of the patient caused by repeated adjustment of the body position.
[0020] The operation is simple and efficient, and the clinical rapid adjustment requirement is adapted. The guide surface design of the sliding component makes the constraint position adjustment not need an additional unlocking step: in the unlocked state, the forward and backward pushing can move the sliding part up and down through the guide surface to realize the rapid adjustment of the position; in the locked state, the forward pushing can automatically unlock and adjust, and the backward pushing can keep the locking. Combined with the handle formed by the extension of the limiting part and the handle groove on the flexible constraint part, the medical staff can easily complete the lifting and unlocking, sliding positioning and other operations, and the whole process does not need complex tools, which adapts to the clinical requirement of rapid preparation of the body position in the anesthesia operation.
[0021] The flexible constraint and ergonomic design improve the patient comfort. The flexible constraint part is made of soft cloth or soft net, which can form a close wrapping when directly contacting with the patient's body, so as to avoid the compression damage caused by the hard constraint. In addition, the "on-demand constraint" mode can constrain only the part that cannot be fixed by the patient according to the self-position control ability of the patient, so as to reduce unnecessary body restraint and enhance the patient's cooperation degree.
[0022] Flexible structure adaptation, taking into account different scenarios and crowds. The device components are designed with high flexibility: the slide rail can be fixed or detachably connected, facilitating flexible disassembly according to the medical equipment use requirements; the flexible restraint material can be selected according to the patient's skin sensitivity and seasonal requirements; the guide surface inclination angle, the cooperation mode of the plug-in and sliding parts, etc., can adapt to the restraint requirements of patients of different sizes. At the same time, it supports dual restraint components for comprehensive restraint or single restraint components for targeted restraint, which is suitable for both critically ill patients who cannot maintain their body position independently and light patients who only need local assistance, reducing the use cost of single-scenario equipment.

Detailed Implementation
[0026] The invention will now be further described with reference to the accompanying drawings.
[0027] Reference Figures 1-14 As shown, an anesthesia aid device according to this embodiment includes a slide rail 1 and a restraint assembly 2.
[0028] In this embodiment, there are two slide rails 1, which are fixedly installed on the left and right sides of the medical device 3, which can be an operating table or an anesthesia bed. Multiple locking grooves 11 are spaced apart along the length of the upper side of the slide rail 1. The locking grooves 11 are used to cooperate with the constraint component 2 to achieve position locking. In other embodiments, the slide rail 1 can also be connected to the medical device 3 via a detachable structure (such as bolt connection), facilitating flexible assembly and disassembly according to usage requirements.
[0029] In this embodiment, the constraint component 2 includes a sliding component 21 and a flexible constraint member 22. There are two sliding components 21, each slidably fitted to two slide rails 1. In this embodiment, to achieve stable constraint on the patient, two constraint components 2 are symmetrically arranged on both sides of the length of the medical device 3 (bed): the constraint component 2 near the head of the bed is used to surround and constrain the patient's shoulders and head, and the constraint component 2 near the foot of the bed is used to surround and constrain the patient's legs and buttocks. Through two-point coordinated constraint, the effect of a nurse's hands assisting is simulated to ensure the stability of the patient's curled-up state.
[0030] In this embodiment, the sliding component 21 includes a first slider 211, a second slider 212, a plug 213, and a limiting component 214.
[0031] The first sliding piece 211 is provided with a first sliding groove 2111 which is matched with the slide rail 1, so that the first sliding piece 211 can slide forward and backward along the slide rail 1. The upper end of the first sliding piece 211 is provided with a second sliding groove 2112 which is communicated with the first sliding groove 2111. In the embodiment, the first sliding groove 2111 and the slide rail 1 are cylindrical, and the rotation of the first sliding piece 211 is limited by the cooperation of the first rotation limiting surface 2111a and the second rotation limiting surface 1a; in other embodiments, the cross section of the first sliding groove 2111 can also be rectangular, and the cross section of the slide rail 1 can also be a matching rectangle, so that the axial rotation of the first sliding piece 211 can be naturally limited.
[0032] The second sliding piece 212 is slidably arranged in the second sliding groove 2112, and the lower end of the second sliding piece 212 is provided with a first guide surface 212a and a second guide surface 212b on the front and rear sides respectively. The first guide surface 212a is inclined from front to back and from top to bottom, and the second guide surface 212b is inclined from front to back and from bottom to top. In the embodiment, the inclination angles of the first guide surface 212a and the second guide surface 212b are 45 degrees, which facilitates the smooth guiding of the second sliding piece 212 to move up and down during sliding; in other embodiments, the inclination angles can also be set to 30 degrees or 60 degrees according to actual needs. The upper end of the second sliding piece 212 is provided with a slot 2121 which penetrates the second guide surface 212b.
[0033] The insert 213 is inserted into the slot 2121, and the limiting piece 214 is arranged at the upper end of the insert 213 and abuts against the upper end of the second sliding piece 212. When the limiting piece 214 abuts against the upper end of the second sliding piece 212, the lower end of the insert 213 does not protrude to the lower side of the lower end of the second sliding piece 212, and the height difference between the two is less than the depth of the slot 2121, so that the insert 213 cannot fall off from the slot 2121. In the embodiment, the limiting piece 214 and the insert 213 are integrally formed, which has higher strength; in other embodiments, the two can also be fixed by threaded connection.
[0034] In the embodiment, the opposite ends of the flexible constraint piece 22 are connected with the inserts 213 of the two sliding assemblies 21 respectively, which is used to constrain the patient's body and assist in maintaining the knee chest lateral position. In the embodiment, the flexible constraint piece 22 is made of soft cloth material, which is soft and breathable, and improves the comfort of the patient; in other embodiments, it can also be made of soft net material, which has better air permeability.
[0035] In order to improve the connection stability, the upper end of the first sliding piece 211 and the upper end of the second sliding piece 212 are both extended to the side of the insert 213 which is connected with the flexible constraint piece 22, and the side of the first sliding piece 211 and the side of the second sliding piece 212 are respectively provided with a first accommodation slot 2113 and a second accommodation slot 2122 which are matched with the flexible constraint piece 22 and provide accommodation space for the flexible constraint piece 22.
[0036] In the embodiment, the second sliding member 212 is provided with a rotation-stopping part 2123 on the side, the rotation-stopping part 2123 extends into the second accommodating slot 2122, and the rotation-stopping part 2123 and the second accommodating slot 2122 are matched to limit the axial rotation of the second sliding member 212 in the second sliding groove 2112. In the embodiment, the rotation-stopping part 2123 is a vertical bar-shaped protrusion, and the second accommodating slot 2122 is a vertical bar-shaped groove, and the matching effect is stable; in other embodiments, other shapes that match each other can also be used.
[0037] In the embodiment, the upper part of the inner side of the first sliding groove 2111 is a first rotation-stopping surface 2111a, and the upper end of the slide rail 1 is provided with a second rotation-stopping surface 1a matched with the first rotation-stopping surface 2111a, and the first rotation-stopping surface 2111a and the second rotation-stopping surface 1a are matched to limit the axial rotation of the first sliding member 211 on the outer side of the slide rail 1.
[0038] In the embodiment, the longitudinal middle part of each end of the flexible constraint member 22 is provided with a handle slot 221, which is convenient for the user to put his fingers through to hold the sliding assembly 21 or the plug-in part 213 for operation. The limiting part 214 extends upward to form a handle, and the length of the handle is 5 cm in the embodiment, which is convenient for holding; in other embodiments, the length or shape can also be adjusted according to the use requirements.
[0039] Preferably, when the limiting part 214 abuts against the upper end of the second sliding member 212, the lower end of the plug-in part 213 is flush with the lower end of the second sliding member 212, at this time, the abutting area of the plug-in part 213 and the side surface of the lock slot 11 is large, which can improve the abutting stability.
[0040] In the embodiment, the lower end of the plug-in part 213 is provided with a circular truncated cone part 2131 with a wide lower end and a narrow upper end, and the angle between the side surface corresponding to the side surface abutting against the plug-in part 213 and the bottom surface of the lock slot 11 is less than 90 degrees. In the embodiment, the angle is 70 degrees, and the side surface of the circular truncated cone part 2131 is inclined at an angle of 20 degrees, and the two are matched to effectively limit the upward sliding of the plug-in part 213; in other embodiments, it can also be set to 80 degrees and 10 degrees and other combinations, as long as it can achieve stable limiting.
[0041] It should be emphasized that when the plug-in part 213 is not inserted into the lock slot 11 (i.e. in the unlocked state), if the sliding assembly 21 is pushed and pulled forward and backward (since the two sliding assemblies 21 are symmetrically arranged, therefore, the side of the flexible constraint member 22 contacting the patient is regarded as the front, and the side away from the patient is regarded as the back), the second sliding member 212 can contact the edge of the lock slot 11 through the first guide surface 212a or the second guide surface 212b, which will guide the second sliding member 212 to slide upward, that is, when the sliding assembly 21 is pushed and pulled forward and backward, the position can be directly adjusted without additional operation.
[0042] When the plug-in part 213 is inserted into the lock slot 11 (i.e. in the locked state), if the sliding assembly 21 is pushed forward, the first guide surface 212a can smoothly contact the edge of the lock slot 11 to guide the second sliding part 212 to slide upward, so as to drive the plug-in part 213 to move upward synchronously and disengage from the lock slot 11 through the limiting part 214, that is, the position can be directly adjusted when the sliding assembly 21 is pushed forward; but when the sliding assembly 21 is pushed backward, the second guide surface 212b cannot contact the edge of the lock slot 11, but contacts the inner wall of the lock slot 11 through the side surface of the plug-in part 213 (in this embodiment, through the circular truncated cone part 2131). Due to the design of the inclined angle between the circular truncated cone part 2131 and the inner wall of the lock slot 11, a wedge-shaped fit is formed, so that the second sliding part 212 cannot be guided to slide upward, that is, the position cannot be adjusted when the sliding assembly 21 is pushed backward, but the position is locked, which can ensure that the backward reaction force of the patient's body during the restraint of the patient will not cause the sliding assembly 21 to loosen, and the stability of the restraint is ensured.
[0043] If it is necessary to adjust backward or completely unlock, the plug-in part 213 can be pulled upward (by holding the limiting part 214), so that the circular truncated cone part 2131 disengages from the lock slot 11, and at this time the second sliding part 212 can freely slide upward and downward, and the sliding assembly 21 returns to the state of being freely adjustable forward and backward.
[0044] In this embodiment, two sets of restraint assemblies 2 (corresponding to the shoulder and hip restraint, respectively) are provided, and the two sets of assemblies may have the sliding demand in the forward and backward directions during adjustment: the restraint assembly 2 close to the head of the bed may slide toward the tail of the bed, and the restraint assembly 2 close to the tail of the bed may slide toward the head of the bed. Therefore, the front and rear walls of the lock slot 11 are designed to be inclined in the same way as described above (i.e. the included angle between the front wall and the bottom surface and the included angle between the rear wall and the bottom surface are both less than 90 degrees), so as to adapt to the locking demand of the two sets of restraint assemblies 2 in different sliding directions, and ensure that both of the two restraint assemblies 2 can be stably locked through the corresponding inclined surface.
[0045] The present application also provides an anesthesia auxiliary system, which comprises the above anesthesia auxiliary device and a medical equipment 3, and the anesthesia auxiliary device is connected with the medical equipment 3 through the sliding rail 1 and can be integrated on the medical equipment 3, so as to facilitate clinical use.
[0046] In use, the patient lies on the medical device 3 in a knee chest lateral position, and the medical staff first adjusts the restraint assembly 2 close to the head of the bed to the position of the patient's shoulder, and then adjusts the restraint assembly 2 close to the tail of the bed to the position of the patient's leg and hip. In the process of sliding the sliding assembly 21 forward (facing the patient side) to the appropriate position, when the first guide surface 212a of the second sliding piece 212 is in contact with the edge of the lock slot 11, it will guide the second sliding piece 212 to slide upward, so that the plug-in piece 213 moves upward accordingly; when sliding to the target position, the plug-in piece 213 moves downward under the action of gravity and is inserted into the corresponding lock slot 11 to achieve locking (that is, to prevent sliding backward), so that the flexible restraint piece 22 can form a stable wrapping restraint on the patient's body, replacing the continuous support of the nurse. If adjustment or unlocking is needed, just pull up the limiting piece 214 (handle) to make the plug-in piece 213 exit the lock slot 11, and then adjust the sliding.
[0047] It is worth mentioning that in other embodiments, one set of restraint assemblies 2 can be flexibly selected according to the patient's self-position control ability to achieve more targeted body position assistance. In clinical practice, although some patients may have difficulty maintaining a complete knee chest lateral position, they may have the ability to control a certain part of the body independently: for example, some patients can maintain the forward flexion and fixation of the shoulder by themselves, and only the leg and hip are prone to relaxation and deviation due to muscle weakness or discomfort; or some patients can stably control the flexion posture of the leg and hip, and only the shoulder is prone to backward tilting, causing the body position to deform. For such cases, instead of using two sets of restraint assemblies 2 for comprehensive restraint, a set of restraint assemblies 2 can be installed on the corresponding side of the medical device 3 (bed) in the length direction: if the patient's leg and hip are difficult to control independently, the restraint assembly 2 is installed close to the tail side of the bed, and the flexible restraint piece 22 is used to wrap around the patient's leg and hip to assist in maintaining the flexion posture close to the chest; if the patient's shoulder is difficult to fix independently, the restraint assembly 2 is installed close to the head side of the bed, and the flexible restraint piece 22 is used to adhere to the patient's shoulder to prevent it from deviating. This "on-demand restraint" design not only ensures the stability of the overall knee chest lateral position by fixing the parts that cannot be controlled independently, but also avoids unnecessary restraint of the parts that can be controlled independently by the patient, reduces the area of body restraint, improves the comfort and cooperation of the patient, and also reduces the number of components used, reduces the cost of the device and the operation complexity of the medical staff.
[0048] To sum up, the anesthetic auxiliary device and the anesthetic auxiliary system of the present application, through scientific structure design and flexible use logic, solve the clinical pain points that patients are difficult to maintain the knee chest lateral position independently and rely on nurses for continuous assistance during intraspinal anesthesia. The core advantages are: on the one hand, based on the "double slide rail + double constraint assembly", through the coordinated cooperation of the first sliding piece 211, the second sliding piece 212 and the insert piece 213 in the sliding assembly 21, combined with the wedge-shaped locking structure of the lock groove 11 and the circular table part 2131, the stable constraint of the patient's shoulder and leg is realized, the double hand assistance effect of the nurse is simulated, the artificial continuous support is completely replaced, and the workload of the medical staff is significantly reduced; on the other hand, the device has high flexibility, not only can each component (such as the connection mode of the slide rail 1, the material of the flexible constraint piece 22, the inclination angle of the guide surface, etc.) select the adaptive scheme according to the actual demand, but also can flexibly select the double constraint assembly or the single constraint assembly according to the patient's independent body position control ability, through "on-demand constraint", the body position stability and patient comfort are considered, and the equipment cost and operation complexity are reduced. In addition, the locking and unlocking mechanism of the device is simple and efficient, and the position adjustment can be completed without complex operation, which is suitable for patients of different body types and clinical scenes, provides a safe, reliable and convenient solution for the body position management of intraspinal anesthesia, and has high clinical application value.
