Description

Technical Field

[0001] This invention relates to a reusable sterilizable shockwave therapy anti-recoil protective glove, belonging to the field of medical protective equipment technology. Background Technology

[0002] Shockwave therapy is a common treatment in rehabilitation departments. When administering this treatment, the operator needs to continuously hold the shockwave handle and apply counterforce. This causes the operator's wrist to bear a significant amount of the shockwave's reaction force, making wrist strain a common problem. Currently, there is a lack of dedicated protective measures for shockwave therapy operators, resulting in a high risk of wrist strain, a practical problem that urgently needs to be addressed in the industry. Anti-recoil protective gloves may be an effective solution to reduce vibration and wrist strain, but there are currently no gloves specifically designed for shockwave operation protection. Furthermore, commercially available industrial and sports protective gloves do not adequately filter shockwave vibrations, cannot absorb millisecond-level shockwave recoil, and lack adaptability to medical settings, such as insufficient tactile sensitivity and the inability to be repeatedly sterilized. Summary of the Invention

[0003] The present invention aims to provide an anti-recoil protective glove for shock wave therapy, which solves the industry pain point that existing protective equipment cannot simultaneously achieve high-energy shock absorption and medical-grade disinfection tolerance.

[0004] To achieve the above objectives, the present invention provides a reusable sterilizable shockwave therapy anti-recoil protective glove, comprising a palm area, a knuckle area, and a thenar eminence area. The palm area, from the inside out, includes a first inner lining layer, a dual-function composite damping layer, and a wear-resistant layer. The knuckle area, from the inside out, includes a second inner lining layer, a second impact-resistant layer, a second nano-sterilization layer, and a second scratch-resistant layer. The thenar eminence area includes a third inner lining layer, a third impact-resistant layer, a third nano-sterilization layer, and a third scratch-resistant layer.

[0006] The second and third impact layers are 3D support skeleton layers filled with STF-Kevlar composite material.

[0007] Preferably, it also includes a wrist area extending from the edge of the palm area to the wrist portion, wherein the wrist area comprises, from the inside out, a fourth inner lining layer, an impact-resistant protective functional layer, a transition buffer layer, and an outer wear-resistant layer; the impact-resistant protective functional layer and the transition buffer layer are respectively made of high-density polyurethane foam and low-density polyurethane foam.

[0008] Preferably, the first inner lining layer, the second inner lining layer, and the third inner lining layer are antibacterial quick-drying mesh fabrics with a thickness of 0.6 to 1.2 mm.

[0009] Preferably, the second and third nano-sterilization layers are fluorosilane nano-sterilization layers with a thickness of 3–10 μm.

[0010] Preferably, the wear-resistant layer is a composite layer of microfiber leather and Kevlar mesh, with a thickness of 0.4-1mm.

[0011] Preferably, the second and third anti-scratch layers are elastic spandex covering layers with a thickness of 0.2-0.5 mm.

[0012] Preferably, the fourth inner lining layer is made of antibacterial mesh fabric with a thickness of 0.6 to 1.2 mm.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] (1) The protective glove provided by the present invention has a partitioned composite damping layer that precisely reduces vibration:

[0017] Through non-Newtonian fluid materials ( Aero Solid achieves a shear thickening effect during the impact instant (0.1-2ms), converting mechanical impact energy into heat energy; in addition, it utilizes the viscoelastic hysteresis characteristics of the polyurethane gel layer to dissipate low-frequency vibration energy.

[0018] (2) Disinfection compatibility process improves the disinfection tolerance of gloves:

[0019] exist A nano-interface fusion layer of "SiO2-KH550-PU hybrid coating (NSHC)" is set between the Aero Solid material and the polyurethane gel layer, which can resist alcohol disinfection and is easy to reuse multiple times after disinfection.

[0027] To make the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0028] Example

[0029] This embodiment provides a reusable sterilizable shockwave therapy anti-recoil protective glove. The glove features a partitioned design, specifically divided into a palm area 1, a knuckle area 2, a thenar eminence area 3, a wrist area 4, and a back of the hand area 5. The knuckle area 2 covers the entire finger area, encompassing the fingers and knuckles on both the palm and back of the hand. The wrist area 4 extends from the edge of the palm area 1 to the wrist. The back of the hand area 5 includes the back of the hand corresponding to the palm area 1 and the wrist area 4. The material of the back of the hand area 5 is not limited; any material used in ordinary gloves can be used, such as cotton or other fiber materials. The composition of the remaining functional areas and main materials is as follows: Figure 1As shown, the palm area 1, from the inside out, includes a first inner lining layer 1-1, a dual-function composite damping layer 1-2 (PU gel layer + nano disinfection layer + first impact-resistant layer), and a wear-resistant layer 1-3. The materials and functions of each layer in the palm area are shown in Table 1. The knuckle area 2, from the inside out, includes a second inner lining layer 2-1, a second impact-resistant layer 2-2, a second nano disinfection layer 2-3, and a second anti-scratch layer 2-4. The materials and functions of each layer in the knuckle area are shown in Table 2. The thenar eminence area 3 includes a third inner lining layer 3-1, a third impact-resistant layer 3-2, a third nano disinfection layer 3-3, and a third anti-scratch layer 3-4. The materials and functions of each layer in the thenar eminence area are shown in Table 3. The wrist area 4, from the inside out, includes a fourth inner lining layer 4-1, an impact-resistant protective layer 4-2, a transition buffer layer 4-3, and an outer wear-resistant layer 4-4. The materials and functions of each layer in the wrist area 4 are shown in Table 4.

[0030] In this invention, the first impact-resistant layer is made of D3O material, for example, D3O Labs material. Aero Solid series sheets, made of D3O material, remain relaxed, soft, and elastic under normal conditions. Upon severe impact or compression, the molecules immediately lock together, rapidly tightening and hardening to absorb the external force, forming a protective layer. Once the force disappears, the material returns to its initial relaxed, soft, and elastic state. It can react differently to various impact conditions within nanoseconds, making it an ideal material for shock-absorbing gloves.

[0031] In this invention, the disinfection-resistant material selected is nano-silica hybrid coating (NSHC). The core principle behind its ability to withstand alcohol disinfection lies in its unique composition and microstructure design, which is achieved through a triple mechanism: physical barrier (nano-SiO2 extends the alcohol penetration path by 23 times), chemical bond stability (Si-O-Si bonds can resist alcohol erosion), and molecular-level sealing (PU prepolymer filler achieves a zero-porosity interface).

[0042] In this invention, the main functional layers and materials of each region are shown in Table 5 and Figure 2 As shown:

[0043]

[0044] In this invention, the STF-Kevlar composite material can be selected from DuPont. EXO TM The product. The STF-Kevlar composite material can also be prepared using the method described in the literature (Flexible and lightweight Kevlar composites towards flame retardant and impact resistance with excellent thermal stability): silica particles are dispersed in a highly thermally stable ionic liquid by ball milling to prepare a shear thickening solution (STF), and the STF is then composited onto Kevlar fibers using a "dilution-impregnation-drying" method to prepare a highly flexible STF / Kevlar composite material.

[0045] In this invention, the antibacterial quick-drying mesh fabric used in the inner lining of each zone of the protective glove is selected from quick-drying materials and has undergone antibacterial treatment, preferably antibacterial. Mesh fabric, antibacterial Mesh fabric is a combination of High-performance fabrics with quick-drying technology and antibacterial function.

[0046] In this invention, the 3D support skeleton is made of polyurethane elastic fiber, which is a shape memory functional material that can closely fit and conform to the dynamic changes of the finger joints and the curved surface of the thumb. The 3D support skeleton can be prepared by the following method: a digital model is established based on the three-dimensional scanning data of the patient's hand, a knitting program with a gradient density structure is generated by knitting programming software (such as ShimaSeiki's SDS-ONE APEX), and integrated knitting is carried out using a precision knitting machine with 14-18 needles / inch. After heat setting treatment, a biomimetic skeleton structure that closely fits the finger joints and the curved surface of the thumb is obtained.

[0047] In this invention, A nano-interface fusion layer of "SiO2-KH550-PU hybrid coating (NSHC)" is formed between the Aero Solid sheet and the PU gel layer. Its composition includes: 10% nano-SiO2 sol (particle size 20nm) + 5% KH-550 silane + 2% polyurethane prepolymer + 83% ethanol solvent. The NSHC solution is sprayed onto... Liquid PU gel was coated onto the surface of an Aero Solid sheet (10 μm thick) while it was still undried, and then simultaneously cured at 80°C to form a molecular-level interface fusion; the preparation process is as follows: Figure 3 As shown, the specific steps include:

[0048] Step 1: Preprocessing Aero Solid

[0049] Aero Solid sheets are cleaned with ethanol (to remove release agent) and do not require plasma treatment (NSHC has built-in surface activation function);

[0050] Step 2: Interface spraying

[0051] Precisely spray the NSHC solution onto... Aero Solid sheet surface (film thickness 10μm). At this point, the coating is not fully cured and is in a viscous flow state.

[0052] Step 3: Gel compounding

[0053] Immediately apply the liquid PU gel onto the NSHC coating. The solvent (ethanol) in the NSHC partially dissolves the gel surface, forming an interdiffusion layer.

[0054] Step 4: Simultaneous curing (heated at 80℃)

[0055] Silanes in NSHC Aero Solid sheet surface -OH bonding, polyurethane prepolymer in NSHC crosslinked with PU gel, nano SiO2 embedded in both sides of the material.

[0056] In this invention, the STF-Kevlar composite material itself has alcohol-repellent properties, so there is no need to apply the NSHC nano-interface fusion layer; a hydrophobic layer can be applied instead. The fluorosilane in the composite material has good hydrophobicity.

[0057] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form or substance. It should be noted that those skilled in the art can make several improvements and additions without departing from the present invention, and these improvements and additions should also be considered within the scope of protection of the present invention.
