Abstract
Description
Technical Field
[0001] This utility model relates to the field of restraint belt technology, and in particular to restraint belts for neurosurgical nursing. Background Technology
[0002] Currently, existing restraint straps (such as patent publication number: CN217339049U) disclose a restraint strap for neurosurgical care. Through the adapter sleeve, the movement and adjustment of the chest restraint strap, waist restraint strap, and leg restraint strap are highly convenient. The position can be adjusted according to the patient's height, resulting in a better overall effect. The adapter sleeve can be positioned by clamping the positioning seat, so that the chest restraint strap, waist restraint strap, and leg restraint strap can provide high restraint stability to the patient.
[0003] In the aforementioned patent, the restraint strap is a long strip structure. However, different patients have different limb thicknesses and lengths, so it is not possible to restrain a specific part according to their needs. Especially for patients with limb defects, the use of symmetrical restraint straps can easily result in unnecessary constriction. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a restraint belt for neurosurgical care. It solves the technical problem that restraint belts are long and narrow, but different patients have different limb thicknesses and lengths, making it impossible to restrain a specific part according to their needs. In particular, for patients with limb defects, the use of symmetrical restraint belts can easily result in unnecessary constriction.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A restraint strap for neurosurgical care includes a restraint strap body and two strap strips. Multiple strip-shaped airbags are fixedly installed on the inner side of the restraint strap body, and multiple drawstrings are provided on the outer side of the restraint strap body.
[0007] Each of the straps has two positioning rings fixedly installed inside, and each positioning ring has two slots on its inner side. Each of the straps also has two locking cylinders fixedly installed inside that mate with the positioning rings.
[0008] Preferably, each of the strap strips has an interface fixedly installed on its side end;
[0009] Each locking cylinder has a rotating rod rotatably mounted at its top end, a knob fixedly mounted at the top end of each rotating rod, and a push plate provided at the end of each rotating rod.
[0010] Preferably, each of the locking cylinders has two reset rods inside, and a limit block is fixedly installed at the top of each reset rod;
[0011] One end of the drawstring is embedded in the pre-set rope-threading channel inside the strap strip, and the other end of the drawstring is arranged along the outside of the restraint strap body.
[0012] The restraint strap body has a flexible air tube arranged in its internal interlayer, with one end connected to an interface and the other end branching to connect to each strip-shaped airbag.
[0013] Compared with the prior art, the present invention has the following beneficial effects;
[0014] In this invention, the strap strip drives the locking cylinder to insert into the positioning ring. Then, the knob is turned, and the end of the rotating rod rotates to push the push plate downward. During the downward movement of the push plate, the inclined surface friction pushes two limiting blocks. The limiting blocks are inserted into the slots inside the positioning ring, thereby locking the position of the locking cylinder and the positioning ring. The two sets of restraint strap bodies can be combined and installed together, which can simultaneously restrain different parts of the patient's limbs and expand the restraint coverage.
[0015] In this invention, gas is delivered to the soft trachea inside the restraint band body through the interface at the side end of the strap strip. The gas then enters each strip-shaped air bladder through the trachea branch, causing the strip-shaped air bladder to inflate inside the restraint band body. On the one hand, the inflated strip-shaped air bladder helps to conform to the limb, increasing the stability of the restraint, and the tightness of the restraint can be changed by adjusting the inflation pressure. On the other hand, the inflated strip-shaped air bladder can prevent the restraint band body from directly rubbing against the patient's skin surface. Attached Figure Description

[0022] This application provides a restraint strap for neurosurgical care, effectively solving the problem that restraint straps are long and narrow, but different patients have different limb thicknesses and lengths, making it impossible to restrain a specific part according to needs. Especially for patients with limb defects, using a symmetrical restraint strap can easily lead to excessive restraint. The strap strip drives the locking cylinder to insert into the positioning ring. Then, by rotating the knob, the end of the rotating rod rotates and pushes the push plate downward. During the downward movement of the push plate, the inclined surface friction pushes two limiting blocks, which insert into the slots inside the positioning ring, thereby locking the locking cylinder and the positioning ring. The two sets of restraint strap bodies can be combined and installed together, which can restrain different parts of the patient's limbs at the same time, expanding the restraint coverage.
[0023] Example
[0024] like Figures 1-4 As shown, the technical solution in this application embodiment effectively solves the problem that restraint straps are long and narrow, but different patients have different limb thicknesses and lengths, making it impossible to individually restrain a specific part according to needs. This is especially true for patients with limb disabilities, where using symmetrical restraint straps can easily lead to unnecessary constriction. The overall approach is as follows:
[0025] To address the problems existing in the prior art, this utility model provides a restraint belt for neurosurgical care, including a restraint belt body 11 and two straps 14. Multiple strip-shaped airbags 12 are fixedly installed on the inner side of the restraint belt body 11, and multiple drawstrings 13 are provided on the outer side of the restraint belt body 11. The restraint belt body 11 wraps around the limb, and the drawstrings 13 are either slack or at a preset length. When the straps 14 are pulled, the drawstrings 13 are moved towards the straps 14 by utilizing the connection structure between the straps 14 and the drawstrings 13. The drawstrings 13 tighten along the outer side of the restraint belt body 11. Through the fixed relationship between the drawstrings 13 and the restraint belt body 11, the edge of the restraint belt body 11 is pulled towards the center, reducing the space enclosed by the restraint belt body 11 and achieving tight restraint of the limb.
[0026] Two positioning rings 16 are fixedly installed inside each strap 14. Two slots are provided on the inner side of each positioning ring 16. Two locking cylinders 17 that are connected to the positioning rings 16 are fixedly installed inside each strap 14. By folding the strap 14, the strap 14 is passed through the guardrails on both sides of the hospital bed. The strap 14 is bent and wrapped around the guardrails of the hospital bed. After the end of the strap 14 is bent, it is re-fitted. The strap 14 drives the locking cylinders 17 to insert into the inside of the positioning rings 16.
[0027] Each strap 14 has an interface 15 fixedly installed on its side end. Gas flows into the strip-shaped airbag 12 through the interface 15. The strip-shaped airbag 12 expands and supports the restraint strap body 11. The strip-shaped airbag 12 helps to fit the limb and increase the restraint stability. The tightness of the restraint can also be adjusted by the expansion pressure.
[0028] Each locking cylinder 17 has a rotating rod 19 rotatably mounted on its top end, and a knob 18 is fixedly mounted on the top end of each rotating rod 19. Each rotating rod 19 has a push plate 21 at its end. When the locking cylinder 17 is inserted into the positioning ring 16, the rotating rod 19 is rotated in the forward direction inside the locking cylinder 17 by rotating the knob 18. At the same time, the end of the rotating rod 19 rotates and pushes the push plate 21, driving the push plate 21 to slide downward. The end of the push plate 21 has a protruding structure. The push plate 21 squeezes and rubs against the two limit blocks 23. At the same time, the thread helix angle of the rotating rod 19 and the push plate 21 is less than the friction angle. The rotating rod 19, which stops rotating, can lock itself with the push plate 21.
[0029] Each locking cylinder 17 has two reset rods 22 inside, and each reset rod 22 has a limit block 23 fixedly installed at the top. The push plate 21 presses the two limit blocks 23, and the friction of the inclined surface allows the push plate 21 to push the two limit blocks 23, allowing the limit blocks 23 to slide inside the locking cylinder 17. The side end of the limit block 23 is inserted into the slot inside the positioning ring 16, locking the position of the locking cylinder 17 and the positioning ring 16 to prevent the strap strip 14 from loosening. At the same time, the two sets of restraint strap bodies 11 can be combined and installed together.
[0030] One end of the drawstring 13 is embedded in the pre-set rope channel inside the strap strip 14, and the other end of the drawstring 13 is arranged along the outside of the restraint strap body 11 and is fixedly connected to the restraint strap body 11. When the strap strip 14 is operated, the drawstring 13 is limited and guided by the channel. Pulling the drawstring 13 can shrink the circumference of the restraint strap body 11. By driving the drawstring 13 to move, the restraint strap body 11 is tightened.
[0031] The restraint strap body 11 has a flexible trachea arranged in its internal interlayer. One end is connected to the interface 15, and the other end is forked and connected to each strip-shaped airbag 12. The interface 15 at the side end of the strap strip 14 is connected to the multiple strip-shaped airbags 12 inside the restraint strap body 11 through the trachea. By delivering gas into the interface 15, the strip-shaped airbags 12 are inflated inside the restraint strap body 11. The multiple strip-shaped airbags 12 work together with the restraint strap body 11 to tighten and fix the patient's limbs. At the same time, the inflated strip-shaped airbags 12 prevent friction against the patient's skin surface.
[0032] Working principle:
[0033] The first step involves wrapping the restraint strap body 11 around the patient's limb and then pulling the strap strip 14. Because one end of the drawstring 13 is embedded in the pre-set rope-threading channel inside the strap strip 14 and the other end is fixed to the outside of the restraint strap body 11, the strap strip 14 guides the drawstring 13 to move in its direction by limiting and guiding the drawstring 13 through the channel. The drawstring 13 tightens along the outside of the restraint strap body 11. By utilizing the fixed relationship between the drawstring 13 and the restraint strap body 11, the edge of the restraint strap body 11 is pulled towards the center, reducing the enclosed space of the restraint strap body 11 and achieving the initial tightening restraint of the limb.
[0034] Fold the strap 14 so that it passes through the side rails of the hospital bed, bends and wraps around the bed rails, and then reattaches the end. At this time, the strap 14 drives the locking cylinder 17 to insert into the positioning ring 16. Then, turn the knob 18. The knob 18 drives the rotating rod 19 to rotate forward in the locking cylinder 17. The end of the rotating rod 19 rotates and pushes the push plate 21 to slide downward. The push plate 21 squeezes and rubs the two limit blocks 23. Since the thread helix angle of the rotating rod 19 and the push plate 21 is less than the friction angle, the two can lock themselves after the rotation stops. During the downward movement of the push plate 21, the two limit blocks 23 are pushed by the inclined surface friction. The limit blocks 23 slide in the locking cylinder 17, and their side ends are inserted into the slots inside the positioning ring 16, thereby locking the position of the locking cylinder 17 and the positioning ring 16, preventing the strap 14 from loosening, completing the fixation of the restraint belt to the hospital bed, further ensuring the stability of the limb restraint, and the two sets of restraint belt bodies 11 can be combined and installed through this structure.
[0035] The second step involves supplying gas through the interface 15 at the side end of the strap 14 to the soft trachea inside the restraint strap body 11. The gas then branches off through the trachea and enters each strip-shaped airbag 12, causing the strip-shaped airbag 12 to inflate inside the restraint strap body 11. On the one hand, the inflated strip-shaped airbag 12 helps to conform to the limb, increasing the stability of the restraint, and the tightness of the restraint can be changed by adjusting the inflation pressure. On the other hand, the inflated strip-shaped airbag 12 can prevent the restraint strap body 11 from directly rubbing against the patient's skin surface, improving the patient's wearing comfort.
[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
