Description

Technical Field

[0001] This utility model relates to the field of restraint straps, and in particular to a hand restraint strap for facial surgery. Background Technology

[0002] During facial surgeries such as eyelid surgery, rhinoplasty, and treatment for hemifacial spasm, patients often unconsciously reach out with their hands, contaminating sterile areas and potentially causing infection. Therefore, to ensure patient safety and surgical outcomes, there is an urgent need for a facial surgical hand restraint to prevent patients from extending their hands to the face and contaminating sterile areas. Utility Model Content

[0003] This utility model addresses the problems existing in the prior art by providing a hand restraint strap for facial surgery.

[0004] To achieve the above objectives, the present invention provides a facial surgical hand restraint strap, including a back pressure strap and a wrist strap. Two symmetrically arranged wrist straps are integrally connected to the back pressure strap. A pressure relief ball is connected to the middle of the wrist strap via an elastic cord. A Velcro barbed surface is provided on the lower side of the wrist strap end, and a Velcro rough surface corresponding to the Velcro barbed surface is provided on the lower side of the back pressure strap.

[0005] Furthermore, the back pressure band is divided into three layers, including a medical silicone layer, a memory foam layer, and a medical elastic fabric layer, which are hot-pressed and composited from top to bottom.

[0006] Preferably, the thickness of the medical silicone layer is 1-1.5 mm, the thickness of the memory foam layer is 8-12 mm, and the thickness of the medical elastic fabric layer is 1-2 mm.

[0007] More preferably, the medical silicone layer is provided with a micropore array with a pore size of 0.5 mm and a spacing of 3 mm.

[0008] Furthermore, the wristband is made of medical elastic fabric and is integrally formed with the medical elastic fabric layer of the back pressure belt.

[0009] Preferably, a polyimide film layer is provided on the lower surface of the middle part of the wristband.

[0010] More preferably, the polyimide film layer has a thickness of 0.3 mm.

[0011] Furthermore, the surface of the pressure-reducing ball is provided with several annular anti-slip patterns, the depth of which is 0.2 mm and the width of which is 1 mm.

[0012] Furthermore, the elastic rope is made of elastic silicone.

[0013] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are as follows: The facial surgery hand restraint strap of this utility model can restrain the patient's hands during facial surgery, preventing the patient's hands from reaching the face and contaminating the sterile area; the structure of the back pressure strap and wrist strap is integrally formed, eliminating the potential risk of suture delamination of traditional suture or splicing structures, improving the stability and durability of the overall structure, and reducing friction at contact points to avoid skin redness and swelling caused by prolonged wear; the use of pressure-relieving balls can soothe the patient's mind and divert attention, and the pinching action activates the sensorimotor cortex of the brain, diverting excessive attention from the surgical process and improving patient cooperation.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following describes this utility model in further detail through preferred embodiments.

[0019] Please see the appendix Figure 1-3 As shown, a facial surgical hand restraint strap in this embodiment includes a back pressure strap 1 and a wrist strap 2. Two symmetrically arranged wrist straps 2 are integrally connected to the back pressure strap 1. The middle of the wrist strap 2 is connected to a pressure relief ball 4 through an elastic rope 3. The lower side of the end of the wrist strap 2 is provided with a Velcro barbed surface 5, and the lower side of the back pressure strap 1 is provided with a Velcro rough surface 6 corresponding to the Velcro barbed surface 5.

[0020] Before facial surgery, the patient lies naturally on the back pressure band 1, and the wristband 2 is wrapped around the wrist. The Velcro 5 is attached to the Velcro 5, so that the wrist is fixed by the wristband 2. The patient's weight is used to press the end of the wristband 2 against the bottom of the back pressure band 1 to form double fixation and prevent the patient's hand from reaching the face and contaminating the sterile area. The pressure ball 4 is handed to the patient to squeeze and hold to make them feel relaxed, divert their attention and improve their cooperation.

[0021] Specifically, in some preferred embodiments, the back pressure band 1 is divided into three layers, including a medical silicone layer 101, a memory foam layer 102, and a medical elastic fabric layer 103, which are thermo-pressed and composited from top to bottom; the medical silicone layer 101 is 1-1.5mm thick, providing good support and stability while maintaining softness; the memory foam layer 102 is 8-12mm thick, providing cushioning and comfort, and its slow rebound characteristics adapt to the body's curves; the medical elastic fabric layer 103 is 1-2mm thick, ensuring fit and breathability; the medical silicone layer 101 is provided with a micropore array 8 with a pore size of 0.5mm and a spacing of 3mm to improve breathability.

[0022] Specifically, in some preferred embodiments, the wristband 2 is made of medical elastic fabric and is integrally formed with the medical elastic fabric layer 103 of the back pressure band 1. The integrally formed structure of the back pressure band 1 and the wristband 2 can eliminate the potential risk of suture delamination of traditional suture or splicing structures, improve the stability and durability of the overall structure, reduce friction at contact points, avoid skin redness and swelling caused by prolonged wear, and improve the comfort and safety of hand restraint for surgical patients.

[0023] Specifically, in some preferred embodiments, a polyimide film layer 7 is provided on the lower surface of the middle part of the wristband 2. The polyimide film layer 7 has a thickness of 0.3 mm, which can provide additional support and abrasion resistance, reduce edge friction, and reduce the rate of skin damage.

[0024] Specifically, in some preferred embodiments, the surface of the pressure-reducing ball 4 is provided with several annular anti-slip textures 401. The depth of the anti-slip textures 401 is 0.2mm and the width is 1mm. The pressure-reducing ball 4 uses medical silicone (Shore hardness 30A) to wrap the TPU core, taking into account both soft touch and rebound performance. The anti-slip textures 401 improve the stability of gripping.

[0025] Specifically, in some preferred embodiments, the elastic rope 3 is made of elastic silicone.

[0026] The above description is a preferred embodiment of the present utility model, used to explain the technical solution of the present utility model. Those skilled in the art can also make conventional modifications, equivalent substitutions and improvements within the spirit and principles of the present utility model.
