Description

Technical Field

[0001] This utility model relates to the field of clinical nursing technology, and in particular to an auxiliary carrying strap device. Background Technology

[0002] In clinical medical care, transferring stroke patients or other patients with limited mobility from their beds to wheelchairs or other mobile devices is an extremely challenging task. These patients often have lost or partially lost their mobility due to their condition, making them completely dependent on medical staff for assistance during the transfer.

[0003] Currently, the transfer of bedridden patients (such as from bed to wheelchair) typically requires the collaboration of two or more caregivers, employing traditional manual lifting or assistive devices such as transfer boards. However, these methods have significant drawbacks: firstly, they are extremely physically demanding for caregivers, posing a risk of occupational injury when performed alone; secondly, the patient's weight-bearing areas are prone to pressure injuries, especially for stroke patients with abnormal muscle tone, where improper force may cause secondary injuries; and thirdly, existing sling devices often require the patient to remain seated while wearing them, which is difficult for comatose or severely weakened patients to meet. Utility Model Content

[0004] To overcome at least one of the defects described in the prior art, this invention provides an auxiliary carrying strap device. This solves the problem of complex patient transfer procedures.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] An auxiliary carrying device includes: a wearing unit, which includes a fixing member, a head hole, a binding hole, and a leg hole sequentially from one end to the other; a binding unit located at one end of the wearing unit, which includes a first binding strap and a second binding strap extending backwards from each other, both the first binding strap and the second binding strap passing through the binding hole, and the ends of the first binding strap and the second binding strap being detachably connected; and a carrying strap unit located at the other end of the wearing unit, which includes a first carrying strap and a second carrying strap, both of which are connected to the fixing member.

[0007] By adopting the above solution, the auxiliary carrying device, through the design of the carrying unit, allows caregivers to transfer patients from the bed to the wheelchair as if carrying a backpack, greatly reducing physical burden. The distributed weight-bearing method of the device avoids the risk of occupational injury to caregivers due to prolonged or improper posture. The design of the wearing unit takes into account the patient's body structure. Through the reasonable layout of head holes, binding holes, and leg holes, the device can fit the patient's body closely while distributing pressure and reducing pressure injury. The first and second binding straps of the binding unit are detachable, making it easy to adjust the tightness according to the patient's body shape and condition, avoiding secondary injuries caused by improper force. At the same time, the auxiliary carrying device does not require the patient to maintain a sitting posture for wearing. The design of the wearing unit and binding unit allows the patient to complete the wearing while lying down.

[0008] Furthermore, the wearable unit includes: a front body located between the binding unit and the head hole, with the fastener located at one end of the front body near the head hole; and a rear body located between the back strap unit and the head hole, with the binding hole located at one end of the rear body near the leg hole.

[0009] By adopting the above-mentioned solution, the wearable unit can be flexibly adjusted according to the patient's body shape and condition. For example, for patients of different heights or body types, the length or position of the front and rear main bodies can be adjusted to ensure that the device fits the patient's body closely, providing effective support and fixation. The fastener located at the end of the front main body near the head hole allows it to be positioned on the patient's shoulder or upper chest, improving the fit of the strap. The binding hole is located at the end of the rear main body near the leg hole, allowing it to be positioned around the patient's waist. The wearable unit can be bound to the patient through the binding unit. Once bound, the patient's weight can be effectively distributed and supported, reducing the risk of device damage or patient falls caused by single-point force.

[0010] Furthermore, the fastener includes a first fastener and a second fastener, which are symmetrically arranged on both sides of the head hole. The first fastener is connected to the first strap, and the second fastener is connected to the second strap.

[0011] By adopting the above scheme, the symmetrical design allows caregivers to more quickly locate the fixing parts and smoothly connect them to the straps when putting the device on patients. It also enhances the stability and safety of wearing the device, improves the convenience and efficiency of wearing it, adapts to patients of different body types and conditions, and optimizes the overall structure of the device.

[0012] Furthermore, the leg hole includes a first leg hole and a second leg hole, the first leg hole being disposed at the connection between the first shoulder strap and the rear main body, and the second leg hole being disposed at the connection between the second shoulder strap and the rear main body.

[0013] By adopting the above solution, the patient's legs can pass naturally through the wearable unit, avoiding compression or restraint on the legs, thereby improving wearing comfort. The design of the leg holes helps to distribute the patient's weight more evenly on the wearable unit, reducing single-point force and thus enhancing the stability of the device. Fixing the patient's legs in the wearable unit through the leg holes can provide additional support, helping to maintain the patient's balance and stability during the transfer process.

[0014] Furthermore, the binding hole includes a first binding hole and a second binding hole, wherein the first binding hole is provided corresponding to the first leg hole, and the second binding hole is provided corresponding to the second leg hole.

[0015] By adopting the above scheme, the first binding hole and the second binding hole help to bind the strap unit to the patient, improving the wearing stability.

[0016] Furthermore, a flexible ring pad is provided inside the leg hole, and the flexible ring pad has memory rebound capability.

[0017] By adopting the above-mentioned design, the leg openings can conform to the patient's leg contours, reducing friction and pressure on the patient's skin, thereby improving wearing comfort. The memory rebound capability allows the flexible ring pad to quickly return to its original shape after being compressed, maintaining gentle support for the patient's legs, and preventing discomfort even after prolonged wear. The filling effect of the flexible ring pad makes the leg openings fit the patient's legs more closely, reducing swaying during transfer and enhancing wearing stability. The flexible ring pad has a certain degree of elasticity and plasticity, adapting to patients of different body types and leg circumferences, ensuring that each patient receives the best wearing experience.

[0018] Furthermore, the first strap is connected to a first buckle at one end, and the second strap is connected to a second buckle, with the first buckle and the second buckle engaging.

[0019] By adopting the above solution, the snap-fit ​​design of the first and second buckles allows caregivers to quickly secure the first and second straps together, greatly simplifying the donning process. The buckle design also facilitates quick adjustments based on the patient's body shape and comfort during donning, ensuring a snug but not overly tight fit.

[0020] Furthermore, the fastener is a D-ring buckle.

[0021] By adopting the above-mentioned design, the D-ring buckle's structural design gives it excellent load-bearing capacity. Its sturdy frame and tight fastening mechanism ensure that it is not easily deformed or damaged when subjected to large tensile forces, providing stable support for the patient, while the tightness can be changed through simple sliding and adjustment.

[0022] Furthermore, the flexible ring pad is made of shape memory silicone.

[0023] By adopting the above solution, the flexible ring pad can closely conform to the patient's leg contour while maintaining a soft and comfortable feel, and will not cause pressure even after wearing for a long time; it not only improves the comfort of wearing, but also helps to reduce skin indentations and discomfort caused by wearing for a long time.

[0024] Furthermore, the flexible ring pad is wrapped with a skin-adhesive layer.

[0025] By employing the above-mentioned approach, the skin-contact layer is typically made of soft, skin-friendly materials such as cotton, silk, or special medical-grade textiles. These materials reduce friction between the flexible ring pad and the patient's skin, providing a softer and more comfortable feel. For patients who need to wear the assistive brace for extended periods, the skin-contact layer significantly reduces skin pressure and discomfort, enhancing the overall wearing experience. As a barrier between the flexible ring pad and the skin, the skin-contact layer also effectively prevents silicone or other materials from directly irritating the skin, reducing the risk of skin allergies, redness, or breakage.

[0026] In summary, the auxiliary carrying strap device provided by this utility model has the following technical effects:

[0027] 1. The design of the carrying unit allows caregivers to transfer patients from the bed to the wheelchair as if carrying a backpack. This design greatly reduces the physical burden on caregivers and improves work efficiency.

[0028] 2. The distributed load-bearing method of the device makes the force on the nurse's body more even, avoiding the risk of occupational injury caused by prolonged or improper posture, such as lower back pain, muscle strain, etc.

[0029] 3. The reasonable layout of the head hole, binding hole and leg hole allows the device to fit closely to the patient's body, while distributing pressure and reducing the risk of pressure injury to the weight-bearing parts of the patient's body.

[0030] 4. The first and second straps of the binding unit are detachable, which makes it easy to adjust the tightness according to the patient's body shape and condition, avoids secondary injury caused by improper force, and improves the safety during the transfer process;

[0031] 5. The device does not require the patient to remain seated to wear it. The design of the wearing unit and the binding unit allows the patient to complete the wearing process while lying down. This is especially suitable for patients who are comatose or have severe muscle loss, improving the adaptability and ease of use of the device. Attached Figure Description
