Description

Technical Field

[0001] The invention relates to the technical field of medical care, and in particular to a knee restraint belt for a patient. Background Art

[0002] The patella is the largest sesamoid bone in the human body. It is located in front of the lower end of the femur, inside the quadriceps tendon, wide at the top and pointed at the bottom, rough at the front, and with an articular surface at the back. It articulates with the patellar surface of the femur. The patella has the function of protecting the knee joint and preventing the quadriceps tendon from rubbing against the cartilage surface of the femoral condyle. It has the function of transmitting the power of the quadriceps and participating in the formation of the knee extensor mechanism. It has the function of maintaining the stability of the knee joint in the semi-squatting position, preventing excessive adduction, abduction and flexion and extension of the knee joint, and acting as a chain to increase the rotation ability of the knee joint.

[0003] A restraint belt is a device that can control the occurrence of dangerous behaviors in patients (such as suicide, self-harm, extreme excitement and impulse, and obvious aggressive behavior), prevent patients from hurting others or themselves, and prevent children, patients with high fever, delirium, coma, agitation and critically ill patients from falling out of bed, being hit, scratched, etc. due to weakness, unconsciousness or other reasons, thereby ensuring the safety of patients and ensuring the smooth progress of treatment and care.

[0004] During medical care, patients often need to restrain their knee joints. Different patients have different knee circumferences. However, several existing knee restraints include patella fixation holes, fixing to the bed through the knee joint dimension holes to achieve the fixation effect, and fixing the left and right knee joints together and tying them to the bed with cloth strips to achieve the restraint effect. These implementation methods have many disadvantages, such as:

[0005] (1) The existing restraint belt cannot be adjusted according to the size of the patient's patella or knee joint, is easy to slip off, and cannot adapt to patients of different body shapes. For example, Chinese document 1 (CN211023400U) discloses a new type of adjustable restraint belt for fixing on a hospital bed, including a left restraint belt and a right restraint belt, wherein the left restraint belt is provided with fixing straps at both upper and lower positions of the left front and rear ends of the left restraint belt, and the left adjustment fixing belt device is provided at the right end of the left restraint belt, wherein the left adjustment fixing belt device includes a left adjustment fixing hole, a left fixing strap and a left plug-in column. The zipper changes the restraint belt into an extended restraint belt device, a left adjustment fixing belt device and a right adjustment fixing belt device. Although the extended restraint belt device, the left adjustment fixing belt device and the right adjustment fixing belt device can be disassembled and installed, document 1 also has some shortcomings: the left adjustment fixing hole and the right adjustment fixing hole are fixed and cannot be adjusted, so the restraint belt cannot adapt to the body shapes of different patients. For example, adults and children have different patellar sizes. The restraint belt used to restrain adults is used to restrain children, and the fixing effect of the restraint belt is not good;

[0006] (2) The existing restraint belt is relatively fixed when connected to the bed through the knee joint, which will fix the knee joint too tightly, not only affecting the comfort but also causing poor blood circulation, affecting the patient's postoperative recovery, prolonging the recovery time, and reducing patient satisfaction;

[0007] (3) The existing restraint belt will firmly fix the left and right knee joints after restraint, which will affect the range of motion of the joints on the one hand and hinder medical care operations on the other hand, causing great inconvenience to clinical work. For example, Chinese document 2 (CN111658282A) discloses a knee joint restraint belt, including a cloth body, a left leg fixing belt fixedly arranged on the left side of the cloth body, and a right leg fixing belt fixedly arranged on the right side of the cloth body. The left leg fixing belt and the right leg fixing belt are symmetrically arranged relative to the cloth body. The cloth body is provided with a left leg fixing belt hole and a right leg fixing belt hole. The left leg fixing belt hole is arranged close to the left leg fixing belt, and the right leg fixing belt hole is arranged close to the right leg fixing belt. Although the restraint belt of document 2 can restrain the patient's knee joint, this restraint belt also has some shortcomings. It is fixed between the left and right knee joints and cannot be adjusted, which is inconvenient for medical staff to operate and is not conducive to the patient's recovery after surgery.

[0008] Therefore, the existing restraint belts are prone to slipping, have poor fixation effects, affect patients' postoperative recovery, cannot provide restraint care for different patients, cannot adapt to the needs of different patients, cannot provide patients with comfortable and personalized care, and also affect the development of medical care to a certain extent.

[0009] Therefore, there is an urgent need to develop a knee restraint belt that has a good fixing effect and is convenient for restraining and nursing patients. Summary of the invention

[0022] Preferably, the knee-fixing component is filled with flexible material, so that the restraint belt makes the patient feel comfortable and not tight when fixing the patient's knee joint.

[0023] Compared with the prior art, the solution of the present invention has at least the following beneficial effects:

[0024] (1) The restraint belt of the present invention comprises a knee-fixing component and a knee-adjusting component, and the knee-adjusting component is used to adjust the circumference of the patient's knee joint. The knee-adjusting component can be used to adjust the circumference of the knee joint of different patients, so that the restraint belt can be suitable for patients of different body shapes. A patella hole is opened on the knee-fixing component, and the patient's patella can be exposed through the patella hole, so as to facilitate the movement of the patient's patella and avoid compression of the patient's patella.

[0025] (2) The present invention provides a patellar hole adjustment structure at the patellar hole. The adjustment and fixing assembly is used to adjust the patellar hole for patients with different sizes of patellar holes through the patellar hole adjustment structure. The patellar hole adjustment structure enables the entire restraint belt to better restrain the bodies of different patients, thereby providing patients with a more comfortable care. The adjustment structure of the patellar hole adjustment structure is a sliding adjustment assembly or a sliding buckle assembly, a positioning hole adjustment assembly or a Velcro structure. The patellar hole adjustment structure is used to adjust the size of the patellar hole, thereby solving the problem in the prior art that the restraint belt cannot be adjusted to the size of the patella of different patients.

[0026] (3) The present invention has a first adjustment belt and a first circular adjustment buckle connected to the left and right ends of the knee-fixing component. The first circular adjustment buckle can be adjusted in size. The first circular adjustment buckle can be used to fix the restraint belt to different beds more firmly. In addition, the restraint belt can be used to adjust the fixed distance between patients of different body shapes and the bed through the first adjustment belt, thereby being suitable for fixing patients of different body shapes to the bed.

[0027] (4) The restraint belt of the present invention fixes the patient's knee joint by providing a knee-fixing component to prevent the fixing effect of the restraint belt from deteriorating or slipping over time, and the knee-fixing component is used to improve the fixing effect of the restraint belt.

[0028] (5) The patellar hole adjustment structure of the present invention includes a fit adjustment component, which includes a second Velcro and a fit fixing belt. The second Velcro is attached to the open mouth near the patellar hole. Through the fit of the second Velcro, it can be adjusted according to the different knee joint dimensions of the patient, so that when the restraint belt fixes the patient's knee joint, it does not affect the blood circulation status of the patient's lower limbs, reduces the risk of deep vein thrombosis in the lower limbs, and promotes the patient's postoperative recovery. It solves the problems of excessive traction of the restraint belt when fixing the patient's knee joint, causing the patient's knee joint to be red and blood circulation to be poor. Then, the fit fixing belt is set on the fitting position of the second Velcro. The fit fixing belt can enhance the fitting effect of the second Velcro and prevent the second Velcro from loosening after long-term use.

[0029] (6) The restraint belt of the present invention is filled with flexible material in the knee fixing part, so that when the restraint belt fixes the patient's knee joint, the patient's joint area is not compressed and the blood circulation is not affected. While ensuring the fixation effect, the patient feels comfortable and not tight.

[0030] (7) The present invention sets an elastic rope and a first buckle to connect the elastic rope and the first buckle to form a buckle connection. The buckle connection can be used to adjust the distance between the two knee joints of the patient so that the patient feels comfortable and it is convenient for the patient to change different body positions to ensure the restraint effect. Compared with the existing left and right knee joint restraint belts that are completely fixed together and have no elastic expansion space, the patient can change the body position appropriately, which increases the patient's comfort. Different treatment and nursing work can be carried out according to different body positions, which solves the problem that the restraint belt technology cannot flexibly disassemble the restraint belt to personalize the patient's restraint, thereby ensuring the orderly progress of medical work.

[0031] (8) The left and right knees of the present invention are connected by means of an elastic rope and a first buckle. The elastic rope allows medical staff to loosen the rope at any time according to the nursing needs of the patient and the medical staff. Both knees can be restrained at the same time, or they can be restrained separately or by a single knee joint. This can adapt to different needs, different scenarios, and different patients, and is flexible and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0045] like Figure 1-Figure 2 As shown, the present invention provides a knee restraint belt, including a restraint belt for restraining a patient's knee and fixing it to a hospital bed, the restraint belt includes a knee fixing component 1 and a knee adjusting component 3 arranged on the knee fixing component 1, the knee adjusting component 3 is connected to the knee fixing component 1, the knee fixing component 1 fixes the left and right knee joints of the patient, and the circumference of the patient's knee joint can be adjusted by adjusting the knee adjusting component 3, so that the restraint belt can adapt to patients with different knee joint circumferences, so that the restraint belt can be more widely used.

[0046] Specifically, a patellar hole 11 is provided on the knee-fixing component 1. There are two patellar holes 11, which are symmetrically arranged with each other. The patient's patella can be exposed through the patellar hole 11 to prevent the patient's patella from struggling and causing damage during restraint. A patellar hole adjustment structure 2 is formed on the periphery of the patellar hole 11. The entire restraint belt adjusts the size of the patellar hole 11 through the patellar hole adjustment structure 2, so that the entire restraint belt can better restrain the bodies of different patients and provide patients with a more comfortable care.

[0047] like Figure 3-4 As shown, when the embodiment of the present invention is implemented, a first adjustment belt 12 and a first circular adjustment buckle 13 are connected to the left and right ends of the knee fixing component 1. The restraint belt of the present invention can restrain the patient and fix him on the bed through the first circular adjustment buckle 13.

[0048] like Figure 5The figure is a schematic diagram of the overall structure of the first adjustment belt 12 and the first circular adjustment buckle 13 of the present invention. As shown in the figure, the first adjustment belt 12 is connected to the first circular adjustment buckle 13, and the first circular adjustment buckle 13 itself can be telescopically adjusted, so the aperture size of the first circular adjustment buckle 13 can be adjusted. Therefore, through the adjustment function of the first circular adjustment buckle 13, the restraint belt can be fixed on beds of different specifications and sizes.

[0049] Specifically, the present invention is provided with a first adjusting ring 121 on the first adjusting belt 12, and the first adjusting belt 12 passes through the first adjusting ring 121. The length of the first adjusting belt 12 can be adjusted by the different lengths of the first adjusting belt 12 passing through the first adjusting ring 121. By adjusting the length of the first adjusting belt 12, the distance between patients of different body types and the hospital bed can be adjusted, so that the restraint belt can adapt to patients of different body types. The present invention can adapt to beds of different sizes and specifications by adjusting the size of the first circular adjusting buckle 13. A bayonet 131 is provided on the first circular adjusting buckle 13. The fixing rod of the hospital bed is clamped and released by the bayonet 131, so that a relatively firm fixation between the restraint belt and the hospital bed is achieved, and the fixing method is very simple and convenient. In addition, the restraint belt of the present invention fixes the patient to the hospital bed through the first circular adjusting buckle 13, which can prevent the patient from hurting others / self-injury or other reasons and causing accidents such as falling out of bed, collision, scratching, etc., thereby ensuring the safety of the patient and ensuring the smooth progress of treatment and nursing.

[0050] In other embodiments of the present invention, the first adjustment belt 12 of the restraint belt of the present invention and the first circular adjustment buckle 13 are connected and can be configured as a snap-on connection mode, and a circular buckle is provided. The size of the first circular adjustment buckle 13 can be adjusted by loosening and tightening the circular buckle, and the patient can be restrained and fixed on the bed through the circular buckle.

[0051] like Figure 1-2 As shown, the knee adjustment component 3 is composed of a knee fixing strip 31 and a first Velcro 32 arranged at the end of the knee fixing strip 31. It can be seen from the figure that the knee fixing strips 31 located on the left and right sides of the knee fixing component 1 are cross-fixed on the knee fixing component 1, and the knee fixing strips 31 are passed from the front of the patient's knee joint to the back of the knee joint. In addition, the knee fixing strips 31 are cross-fitted through the first Velcro 32, so that the Velcro can be used to fix the fixed position of the knee joint circumference, which is convenient for medical staff to care for the patient and also facilitates the nursing. It also makes it easier for the restraint belt to be fixed by passing the patellar hole 11 with a cloth belt, which ensures the safety of the patient while increasing the comfort, reducing the force on the patient's knee joint, and preventing excessive pressure from causing blood circulation disorders, resulting in lower limb blood circulation disorders and related complications.

[0052] like Figure 1As shown, an elastic rope 14 and a first buckle 15 are arranged between the two patellar holes 11 of the restraint belt, and the elastic rope 14 and the first buckle 15 are connected to form a buckle connection. The restraint belt adjusts the distance between the two knee joints of the patient by means of a buckle connection. In this way, while ensuring the safety of the patient, the comfort of the patient is also increased, which is convenient for the patient to change different body positions and ensure the restraint effect. Compared with the restraint belts in the prior art in which the left and right knee joint restraint belts are completely fixed together and have no elastic expansion space, the restraint belt of the present invention can solve the problem that the restraint belt technology cannot be flexibly disassembled and the restraint belt cannot be personalized to restrain the patient in the prior art, thereby ensuring the orderly progress of medical work. In addition, such a design enables the elastic rope 14 connected to the left and right knees by means of the elastic rope 14 and the first buckle 15 to be loosened at any time according to the needs of the patient and medical staff, and both knees can be restrained at the same time, or they can be restrained separately or a single knee joint can be restrained, so as to adapt to the restraint of different needs, different scenes and different patients, and is flexible and convenient. While achieving the restraint effect, it can also increase the comfort of the patient and the flexibility of different body positions.

[0053] like Figure 6 As shown, specifically, the patellar hole adjustment structure 2 includes a sliding adjustment component 22, which includes a sliding buckle 211, a sliding body 212 and an adjustment switch 213. One end of the sliding body 212 is connected to the sliding buckle 211, and the adjustment switch 213 is set on the sliding buckle 211. The sliding body 212 is buckled on the sliding buckle 211 through the adjustment switch 213. The sliding buckle 211 is also provided with a sliding space 214 for one end of the sliding body 212 to pass through. First press the adjustment switch 213, and then pull the sliding body 212 to adjust the size of the patellar hole 11. The operation is very convenient.

[0054] like Figure 7 As shown, a plurality of adjustment buckles 215 are provided on the sliding body 212, and the adjustment switch 213 is fixedly arranged on the sliding buckle 211 and exposed on the surface of the sliding buckle 211. Pressing or pulling the adjustment switch 213 causes part of the sliding buckle 211 to be stuck or loosened. The adjustment buckle 215 can be used to adjust the sliding adjustment component 22, thereby achieving adjustment of different sizes of the patellar hole 11.

[0055] like Figure 8 As shown, the patellar hole adjustment structure 2 of the present invention includes a sliding buckle assembly 22, which includes a buckle mechanism 221, a sliding belt 222 and an adjustment assembly 223. The sliding belt 222 passes through the adjustment assembly 223 so that the sliding belt 222 can be adjusted. The buckle mechanism 221 and the sliding belt 222 are connected so that the sliding belt 222 can be fastened and loosened, thereby achieving adjustment of the aperture size of different patellar holes 11.

[0056] like Fig.10As shown, specifically, the buckle mechanism 221 of the present invention includes a first buckle 2211 and a second buckle 2212. The second buckle 2212 is inserted into the first buckle 2211 to tighten the buckle mechanism 221. The first buckle 2211 and the second buckle 2212 are respectively connected to the two ends of the sliding belt 222. The adjustment component 223 uses an adjustable Japanese buckle.

[0057] In specific implementation, the first buckle 2211 of the present invention uses a male buckle, and the second buckle 2212 uses a female buckle. By inserting the male buckle into the female buckle, the sliding belt 222 can be buckled and adjusted. By pulling the male buckle out from the female buckle, the sliding belt 222 can be loosened. The buckle mechanism 221 of the present invention uses a buckle method to buckle or loosen, which is very convenient for medical staff to operate. There is no need to use a complex structure for loosening, which greatly reduces the production cost. In addition, the material of the first buckle 2211 and the second buckle 2212 of the present invention is plastic buckles, which are relatively light and convenient for mass production.

[0058] In other embodiments, the buckle mechanism 221 of the present invention can be selected as a bullet buckle, a Japanese buckle, an airplane buckle, or other mechanisms capable of buckling.

[0059] like Fig. 9 As shown, the patellar hole adjustment structure 2 of the present invention includes a positioning hole adjustment component 23, and the positioning hole adjustment component 23 includes a positioning adjustment belt 231 and a positioning strip 232. The positioning strip 232 is clamped on the positioning adjustment belt 231, and a plurality of positioning holes are opened in the positioning adjustment belt 231, so that the positioning strip 232 can adjust the positioning adjustment belt 231 through the positioning holes, thereby realizing the adjustment of the size of the patellar hole 11.

[0060] like Figure 1 and Figure 3 As shown, specifically, the present invention has an open opening 16 in the knee fixing component 1 near the patellar hole 11, and the patellar hole adjustment structure 2 also includes a fit adjustment component 24, and the fit adjustment component 24 includes a second Velcro 241 and a fit fixing belt 242. The second Velcro 241 of the present invention is fixed near the position of the open opening 16, and the fit fixing belt 242 is arranged next to the second Velcro 241 to prevent the second Velcro 241 from loosening after long-term use. The fit fixing belt 242 can reinforce the position of the second Velcro 241 at the open opening 16, and the size of the patellar hole 11 can be adjusted by the tightness or looseness of the second Velcro 241, which is very convenient for medical staff to operate.

[0061] The present invention fills some flexible materials in the knee fixing component 1, so that when the restraint belt fixes the patient's knee joint, the patient's joint area is not compressed and the blood circulation is not affected, and the patient feels comfortable and not tight while ensuring the fixation effect.

[0062] Embodiment 1:

[0063] like Figure 2 and Figure 4 As shown, the knee adjustment component 3 of the present invention is composed of a knee fixing strip 31 and a first Velcro 32. In specific implementation, the knee fixing strips 31 on the left and right sides of the knee fixing component 1 are cross-fixed on the knee fixing component 1, and the knee fixing strips 31 are passed through the front to the back of the patient's knee joint, and then the first Velcro 32 at the end of the knee fixing strip 31 is used to tighten the knee joint. Since the knee fixing strips 31 are cross-fixed, the back of the patient's knee joint is in a hollow state, which is convenient for the patient to move the back of the knee joint, avoids injury due to force points when the patient breaks free, and avoids affecting the patient's care and recovery. In addition, the present invention provides a patellar hole 11 in front of the restraint belt that restrains the patient's knee, and the patellar hole 11 also facilitates the patient's knee joint to move in front. In this way, the restraint belt with hollow front and back can provide better guarantee for the patient's care and recovery, and can make the patient feel comfortable while restraining the patient.

[0064] Embodiment 2:

[0065] like Fig.11 As shown, it is the patellar hole double adjustment component 25 in the patellar hole adjustment structure 2 of the present invention, and the patellar hole double adjustment component 25 includes a double adjustment belt 251 and an adjustment fixing seat 252. After the double adjustment belt 251 passes through the adjustment fixing seat 252, the left and right ends of the double adjustment belt 251 are respectively connected with a left adjustment buckle 253 and a right adjustment buckle 254. The length of the double adjustment belt 251 is adjusted by the left adjustment buckle 253 or the right adjustment buckle 254. The length of the double adjustment belt 251 passing through the left adjustment buckle 253 or the right adjustment buckle 254 is adjusted separately, so as to adjust the size of the patellar hole 11. The present invention is provided with two left adjustment buckles 253 and right adjustment buckles 254 for adjusting the length of the double adjustment belt 251. When one of the adjustment buckles has a problem, the present invention can still continue to adjust the size of the patellar hole 11 without affecting the use of the restraint belt.

[0066] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
