Description

Technical Field

[0003] The present invention relates to the technical field of medical devices, and particularly relates to a medical rare earth glove for preventing sharp instrument injuries and a preparation method thereof. Background Art

[0004] As a medical protective article, gloves play an important role in providing a sterile barrier during medical operations. Gloves being damaged is a common problem in medical staff's work and is often overlooked. Gloves are mostly damaged during the use of sharp instruments such as surgeries and injections, and the resulting sharp instrument injuries cannot be ignored. Sharp instrument injuries are one of the common occupational hazards in medical staff's work. In medical work, blood-borne diseases such as AIDS, hepatitis B, and hepatitis C greatly increase the potential risk of occupational exposure for medical staff. The psychological pressure and health harm brought by the occurrence of sharp instrument injuries to medical staff are very serious.

[0005] During clinical operations, in order to reduce the occurrence of sharp instrument injuries, medical staff choose to wear single-layer gloves or double-layer gloves by evaluating the operation risk level. Wearing double-layer gloves provides significantly enhanced protection for the operator's hands compared to single-layer gloves. Using double-layer gloves during surgical operations can reduce the possibility of the inner layer gloves being punctured. However, most existing double-layer gloves are simply stacked and worn, and the materials of the two pairs of gloves are not effectively bonded, which affects the comfort of medical staff when wearing and the perception during hand operations. When wearing single-layer gloves, the comfort and operation perception of medical staff's hands are relatively high, but they are easily penetrated. Moreover, in order to ensure the perception of the hands for existing medical gloves, the glove size is often designed too small, so that the gloves can adhere to the hands through the elasticity of the gloves themselves. However, small glove sizes can cause problems in wearing convenience.

[0006] In summary, existing medical gloves in the prior art have problems of being easily penetrated and inappropriate sizes affecting hand perception. Summary of the Invention

[0016] Step 1: Prepare rare earth-doped zinc oxide nanomaterials.

[0017] Step 2: Prepare an aqueous system nano-functional slurry.

[0018] Step 3: Add the aqueous system nano-functional slurry into the latex used for conventional glove production and stir it so that the aqueous system nano-functional slurry is uniformly and stably dispersed in the latex, and then produce it according to the conventional production process of latex gloves.

[0020] Further, the steps of the preparation method of the rare earth-doped zinc oxide nanomaterials are as follows:

[0021] Step 1-1: Weigh 25-45 parts of one of zinc nitrate, zinc sulfate or zinc acetate by mass and put it into a flask. Add 55-75 parts of deionized water and stir well to dissolve it.

[0022] Step 1-2: Add 35-55 parts of a mixture of one or more of lanthanum chloride heptahydrate, gadolinium nitrate hexahydrate or cerium chloride heptahydrate into the flask and stir evenly.

[0023] Step 1-3: Add 15-35 parts of polytetramethylsilane into the flask, set the temperature at 60-80 °C, and continue to stir for 3-7 hours.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0045] Embodiment 1:

[0046] Please refer to FIGS. 1-7. A medical rare earth glove for preventing sharp object injuries includes a glove body 1 produced from latex added with a water-based nano-functional slurry. A hollow rubber tube 3 is provided at the cuff position of the glove body 1. The hollow rubber tube 3 is fixed to the cuff position of the glove body 1 by gluing. A locking assembly 2 is hermetically connected to the back of the glove body 1. The locking assembly 2 includes a cylinder 21. A ring tube 23 for air extraction and inflation is provided inside the cylinder 21. The ring tube 23 communicates with a ventilation component 25 and the hollow rubber tube 3. The ventilation component 25 is located inside the glove body 1. While injecting the gas in the ring tube 23 into the hollow rubber tube 3, the ring tube 23 inhales the air inside the glove body 1 into the ring tube 23 through the ventilation component 25.

[0047] Specifically, in the present invention, by using latex added with a water-based nano-functional slurry to produce the glove body 1, the puncture resistance of the glove can be significantly improved, and the risk of infection on the hands of medical staff can be reduced. By extracting the air inside the glove body 1 through the ring tube 23 and at the same time sending the gas in the ring tube 23 into the hollow rubber tube 3, not only does the hollow rubber tube 3 expand and closely adhere to the wrist of the medical staff, making the glove body 1 more stable when worn, but also the air between the glove body 1 and the hand of the medical staff is evacuated, making the glove body 1 more closely adhere to the hand and improving the perception ability of the hand.

[0048] Further, a knob 24 is rotatably arranged inside the cylinder 21. The bottom of the knob 24 is clamped inside the cylinder 21. The bottom of the knob 24 is connected to a plunger 26 through a connecting rod 241. An annular cavity 231 is formed inside the annular tube 23. The plunger 26 is slidably arranged inside the annular cavity 231. A partition 233 is fixedly connected inside the annular cavity 231. One side of the partition 233 communicates with the air vent 25, and the other side of the partition 233 communicates with the hollow rubber tube 3.

[0049] Specifically, referring to Figure 5 , the bottom of the knob 24 is stuck inside the cylinder 21 and cannot be pulled outwards. Referring to Figure 6 , the top of the connecting rod 241 is fixedly connected to the bottom of the knob 24, the other end of the connecting rod 241 is fixedly connected to the plunger 26, and the connecting rod 241 is slidably arranged inside the guiding groove 232. The guiding groove 232 is a rectangular groove formed on the annular tube 23. The guiding groove 232 communicates with the annular cavity 231 to limit the movement range of the connecting rod 241. When the knob 24 is turned, the plunger 26 is driven to slide inside the annular cavity 231, thereby changing the amount of gas inside the glove body 1 and the hollow rubber tube 3.

[0050] Further, the bottom of the cylinder 21 is threadedly connected to a bottom plate 22. The bottom plate 22 is adhesively attached to the back of the glove body 1. A round hole 234 is formed on one side of the annular tube 23 near the air vent 25. The air vent 25 passes through the glove body 1 and the bottom plate 22 and then is inserted into the round hole 234 to be hermetically connected to the annular tube 23. The air vent 25 includes a cushion plate 251. The top of the cushion plate 251 is fixedly connected to a first connecting pipe 252. A sealing ring 253 is fixedly sleeved outside the first connecting pipe 252. The top of the first connecting pipe 252 is fixedly connected to a hollow frustum-shaped pipe 254. Two rectangular grooves 255 are formed on the hollow frustum-shaped pipe 254. The formation of the rectangular grooves 255 provides space for the deformation of the hollow frustum-shaped pipe 254. The diameter of the bottom of the hollow frustum-shaped pipe 254 is larger than the diameter of the top of the first connecting pipe 252, which enables the hollow frustum-shaped pipe 254 to be clamped inside the annular cavity 231 after passing through the round hole 234. Four air inlets 2511 are formed on the cushion plate 251. The four air inlets 2511 communicate with the inner cavity of the annular tube 23 through the first connecting pipe 252. The setting of the cushion plate 251 enables a gap to be formed between the glove body 1 and the back of the staff, facilitating the suction of the air inside the glove body 1 into the annular tube 23.

[0051] Specifically, referring to Figure 4 , by setting the cylinder 21 and the bottom plate 22 to be threadedly connected, it is convenient to install parts such as the knob 24 and the annular tube 23 inside the cylinder 21. Referring to Figure 1 and Figure 6, after gluing the bottom plate 22 to the back of the glove body 1, insert the hollow frustum tube 254 and the first connecting tube 252 through the small holes opened on the glove body 1 from the inside of the glove body 1 and then insert them into the round hole 234. The hollow frustum tube 254 squeezes the round hole 234. Under the action of force, the hollow frustum tube 254 deforms and passes through the round hole 234. Subsequently, the hollow frustum tube 254 resumes its deformation and clamps the hollow frustum tube 254 in the annular cavity 231. At this time, the cushion plate 251 and the bottom plate 22 tightly clamp the back of the glove body 1 to ensure the sealing performance, and the sealing ring 253 is squeezed and deformed and clamped in the round hole 234, so that the annular cavity 231 is sealed.

[0052] Further, a second connecting tube 27 is fixedly connected to the side of the annular tube 23, and a third connecting tube 31 is fixedly connected to the hollow rubber tube 3. The third connecting tube 31 is inserted into the second connecting tube 27, so that the inner cavity of the hollow rubber tube 3 is communicated with the inner cavity of the annular tube 23.

[0053] Specifically, refer to Figure 3 and Figure 6 , the outer side of the top of the third connecting tube 31 is made of soft rubber material. When the third connecting tube 31 is inserted into the second connecting tube 27 through the hole opened on the second connecting tube 27 by extrusion, the inner cavity of the third connecting tube 31 is communicated with the inner cavity of the annular tube 23, and when the third connecting tube 31 squeezes the hole on the second connecting tube 27, the surface of the third connecting tube 31 deforms and is clamped in the second connecting tube 27, ensuring the sealing performance between the third connecting tube 31 and the second connecting tube 27.

[0054] Further, refer to Figures 1 to 7 , first put the glove body 1 on the hand, refer to Figure 3 and Figure 6 , then turn the knob 24 counterclockwise. The knob 24 drives the connecting rod 241 to rotate counterclockwise, and the plunger 26 slides counterclockwise in the annular cavity 231, so that the plunger 26 squeezes the gas in the annular cavity 231 into the hollow rubber tube 3. At the same time, a negative pressure is formed on one side of the round hole 234 opened in the annular cavity 231, and the air in the glove body 1 is sucked into the annular cavity 231. This not only makes the hollow rubber tube 3 expand and closely adhere to the wrist of the medical staff, making the glove body 1 more stable when worn, but also evacuates the air between the glove body 1 and the hand of the medical staff, making the glove body 1 more closely adhere to the hand and improving the perception ability of the hand.

[0055] Further, a preparation method of a medical rare earth glove for preventing sharp object injury, the steps included in the method are as follows:

[0056] Step 1: Prepare rare earth-doped zinc oxide nanomaterials,

[0057] Step 2: Prepare a water-based nano-functional slurry,

[0058] Step 3: Add the aqueous nano-functional slurry into the latex used for the production of conventional gloves and stir to make the aqueous nano-functional slurry uniformly and stably dispersed in the latex, and then produce according to the conventional production process of latex gloves.

[0059] Step 4: Install the locking component 2 and the hollow rubber tube 3 at the position of the glove cuff.

[0060] In the present invention, the steps of the preparation method of the rare earth-doped zinc oxide nanomaterial are as follows:

[0061] Step 1-1: Weigh 25 parts by mass of one of zinc nitrate, zinc sulfate or zinc acetate and put it into a flask, add 75 parts of deionized water and stir well to dissolve.

[0062] Step 1-2: Add 35 parts of a mixture of one or several of lanthanum chloride heptahydrate, gadolinium nitrate hexahydrate or cerium chloride heptahydrate into the flask and stir evenly.

[0063] Step 1-3: Add 15 parts of polytetramethylsilane to the flask, set the temperature at 60 °C, and continue to stir for 6 hours.

[0064] Step 1-4: Then add 15 parts of one of ammonia water, urea, ammonium carbonate or sodium hydroxide to the solution and continue to stir for 6 hours.

[0065] After the reaction is completed, filter the suspension in the flask by suction filtration, dry the obtained solid substance at 50 °C, then put it into a muffle furnace at 800 °C and calcine for 6 hours, and take it out after natural cooling, which is the rare earth-doped zinc oxide nanomaterial powder.

[0066] Using an organic weak acid compound as a raw material to prepare a precursor, melamine cyanurate as a linking component, and deionized water as a solvent, a metastable buffer solution is obtained through a reflux reaction at 100 °C. Then, a rare earth nitrate hexahydrate compound or a rare earth chloride compound is added to the buffer solution, mixed and ultrasonicated. Under the condition of a temperature of 60 °C, the reaction environment is adjusted by slowly dropping an alkaline precipitation solution, and a nano-particle dispersion liquid containing rare earth lanthanum element or cerium element is obtained at pH = 11, so as to control the morphology and size of the material. Then, through drying treatment and high-temperature calcination, the excess organic substances and impurities are removed. At the same time, by calcining at a specified temperature, the final rare earth-doped zinc oxide nanomaterial with a lamellar shape is obtained.

[0067] Furthermore, the preparation method of the aqueous nano-functional slurry is as follows:

[0068] Among them, weigh the rare earth-doped zinc oxide nanomaterial and deionized water by mass, mix them evenly, then add a dispersant, and perform multi-stage grinding and dispersion in a sand mill to obtain an aqueous nano-functional slurry with a slurry particle size of 100 nm.

[0069] Among them, the mass ratio of the rare earth-doped zinc oxide nanomaterial: deionized water: dispersant is 10:57:0.5.

[0070] Among them, the dispersant is one or a mixture of several of cetyltrimethylammonium bromide, polyvinylpyrrolidone, modified styrene maleic acid copolymer solution, modified polymer block copolymer, and high molecular weight silane copolymer containing a pigmentophilic group.

[0071] Specifically, the material is further processed by sand grinding to achieve the purpose of reducing the particle size. The calcined rare earth nanocomposite filler is added to a certain amount of solvent at a solid content concentration of 10%, and the solvent is deionized water or an organic solvent such as ethanol or ethylene glycol. 0.5% of sodium dodecylbenzenesulfonate or cetyltrimethylammonium chloride is added to play an auxiliary dispersion role. The nanoscale rare earth nanocomposite filler slurry suspension with a Dv90 of 100 nm is obtained by sand grinding with a Langling sand mill for 8 h.

[0072] In the present invention, the manufacturing steps of the glove body 1 are as follows: Weigh a certain amount of rare earth nanocomposite filler slurry suspension according to an addition amount of 2% of the rare earth nanocomposite filler slurry suspension, add it to the rubber latex, and stir well to make it evenly mixed. Then, prepare a mold in the specific shape of a human hand made of aluminum or ceramic. After thoroughly cleaning the mold to remove any residues or impurities that may affect the product quality, immerse the mold in a coagulant and dry it. The coagulant can help the liquid latex adhere to the mold. After the mold is treated with the coagulant and dried, it will enter the liquid latex pool. The latex mixed with the rare earth material reacts with the coating on the mold, forming a gel-like substance and tightly adhering to the mold. This step requires strict control of the latex temperature and dipping speed. Then, the rubber glove is dried and shaped for 10 min, then coated with a smooth coating, and then vulcanized at 110 °C for 30 min to obtain the glove body 1.

[0073] Example Two:

[0074] Please refer to FIGS. 1-7. A medical rare earth glove for preventing sharp object injuries includes a glove body 1 produced from latex added with a water-based nano-functional slurry. A hollow rubber tube 3 is provided at the cuff position of the glove body 1. The hollow rubber tube 3 is fixed to the cuff position of the glove body 1 by gluing. A locking assembly 2 is hermetically connected to the back of the glove body 1. The locking assembly 2 includes a cylinder 21. A circular tube 23 for air extraction and inflation is arranged inside the cylinder 21. The circular tube 23 communicates with an air vent member 25 and the hollow rubber tube 3. The air vent member 25 is located inside the glove body 1. While injecting the gas in the circular tube 23 into the hollow rubber tube 3, the circular tube 23 inhales the air inside the glove body 1 into the circular tube 23 by using the air vent member 25.

[0075] Specifically, by using latex containing water-based nano-functional slurry to produce the glove body 1, the present invention can significantly improve the puncture resistance of the glove and reduce the risk of infection on the hands of medical staff. By extracting the air inside the glove body 1 through the circular tube 23, the gas in the circular tube 23 is simultaneously transported into the hollow rubber tube 3. This not only makes the hollow rubber tube 3 expand and closely adhere to the wrist of the medical staff, making the glove body 1 more stable when worn, but also evacuates the air between the glove body 1 and the hand of the medical staff, making the glove body 1 fit more closely to the hand and enhancing the hand's perception ability.

[0076] Furthermore, a knob 24 is rotatably arranged inside the cylinder 21. The bottom of the knob 24 is clamped inside the cylinder 21. The bottom of the knob 24 is connected to a plunger 26 through a connecting rod 241. A circular cavity 231 is formed inside the circular tube 23. The plunger 26 is slidably arranged inside the circular cavity 231. A partition 233 is fixedly connected inside the circular cavity 231. One side of the partition 233 communicates with a ventilation member 25, and the other side of the partition 233 communicates with the hollow rubber tube 3.

[0077] Specifically, referring to Figure 5 , the bottom of the knob 24 is stuck inside the cylinder 21 and cannot be pulled outwards. Referring to Figure 6 , the top of the connecting rod 241 is fixedly connected to the bottom of the knob 24, the other end of the connecting rod 241 is fixedly connected to the plunger 26, and the connecting rod 241 is slidably arranged inside a guiding groove 232. The guiding groove 232 is a rectangular groove formed on the circular tube 23. The guiding groove 232 communicates with the circular cavity 231 to limit the movement range of the connecting rod 241. When the knob 24 is turned, the plunger 26 is driven to slide inside the circular cavity 231, thereby changing the amount of gas inside the glove body 1 and the hollow rubber tube 3.

[0078] Further, the bottom of the cylinder 21 is threadedly connected to a bottom plate 22, and the bottom plate 22 is adhesively bonded to the back of the glove body 1. A round hole 234 is formed on one side of the circular ring tube 23 close to the ventilation member 25. After passing through the glove body 1 and the bottom plate 22, the ventilation member 25 is inserted into the round hole 234 and is hermetically connected to the circular ring tube 23. The ventilation member 25 includes a cushion plate 251. A first connecting tube 252 is fixedly connected to the top of the cushion plate 251. A sealing ring 253 is fixedly sleeved on the outer side of the first connecting tube 252. A hollow frustum tube 254 is fixedly connected to the top of the first connecting tube 252. Two rectangular grooves 255 are formed on the hollow frustum tube 254. The formation of the rectangular grooves 255 provides space for the deformation of the hollow frustum tube 254. The diameter dimension of the bottom of the hollow frustum tube 254 is larger than the diameter dimension of the top of the first connecting tube 252. This enables the hollow frustum tube 254 to be clamped in the circular ring cavity 231 after passing through the round hole 234. Four air inlets 2511 are formed on the cushion plate 251. The four air inlets 2511 are communicated with the inner cavity of the circular ring tube 23 through the first connecting tube 252. The setting of the cushion plate 251 enables a gap to be formed between the glove body 1 and the back of the staff, facilitating the suction of the air in the glove body 1 into the circular ring tube 23.

[0079] Specifically, referring to Figure 4 , by setting the cylinder 21 and the bottom plate 22 to be threadedly connected, it is convenient to install parts such as the knob 24 and the circular ring tube 23 in the cylinder 21. Referring to Figure 1 and Figure 6 , after adhesively bonding the bottom plate 22 to the back of the glove body 1, the hollow frustum tube 254 and the first connecting tube 252 are passed through the small hole formed on the glove body 1 from the inner side of the glove body 1 and then inserted into the round hole 234. The hollow frustum tube 254 squeezes the round hole 234. Under the action of force, the hollow frustum tube 254 deforms and passes through the round hole 234. Subsequently, the hollow frustum tube 254 resumes deformation and clamps the hollow frustum tube 254 in the circular ring cavity 231. At this time, the cushion plate 251 and the bottom plate 22 tightly clamp the back of the glove body 1 to ensure the sealing performance. The sealing ring 253 is squeezed and deformed and clamped in the round hole 234, so that the circular ring cavity 231 is sealed.

[0080] Further, a second connecting tube 27 is fixedly connected to the side of the circular ring tube 23. A third connecting tube 31 is fixedly connected to the hollow rubber tube 3. The third connecting tube 31 is inserted into the second connecting tube 27, so that the inner cavity of the hollow rubber tube 3 is communicated with the inner cavity of the circular ring tube 23.

[0081] Specifically, referring to Figure 3 and Figure 6, the outer side of the top of the third connecting pipe 31 is made of soft rubber. When the third connecting pipe 31 is inserted into the second connecting pipe 27 through the hole opened on the second connecting pipe 27 by extrusion, the inner cavity of the third connecting pipe 31 is communicated with the inner cavity of the circular pipe 23. And when the third connecting pipe 31 extrudes the hole on the second connecting pipe 27, the surface of the third connecting pipe 31 deforms and is clamped in the second connecting pipe 27, ensuring the sealing performance between the third connecting pipe 31 and the second connecting pipe 27.

[0082] Further, referring to Figures 1 to 7 , first put on the glove body 1 on the hand, referring to Figure 3 and Figure 6 , then turn the knob 24 counterclockwise. The knob 24 drives the connecting rod 241 to rotate counterclockwise, and the plunger 26 slides counterclockwise in the circular cavity 231, so that the plunger 26 squeezes the gas in the circular cavity 231 into the hollow rubber tube 3. At the same time, a negative pressure is formed on one side of the circular hole 234 opened in the circular cavity 231, sucking the air in the glove body 1 into the circular cavity 231. This not only makes the hollow rubber tube 3 expand and closely adhere to the wrist of the medical staff, making the glove body 1 more stable when worn, but also evacuates the air between the glove body 1 and the hand of the medical staff, making the glove body 1 more closely adhere to the hand and improving the perception ability of the hand.

[0083] Further, a preparation method of a medical rare earth glove for preventing sharp object injuries, the steps included in the method are as follows:

[0084] Step 1: Prepare rare earth-doped zinc oxide nanomaterials,

[0085] Step 2: Prepare a water-based nano-functional slurry,

[0086] Step 3: Add the water-based nano-functional slurry to the latex used for the production of conventional gloves and stir, so that the water-based nano-functional slurry is uniformly and stably dispersed in the latex, and then produce according to the conventional production process of latex gloves.

[0087] Step 4: Set the locking assembly 2 and the hollow rubber tube 3 at the position of the glove cuff.

[0088] In the present invention, the steps of the preparation method of the rare earth-doped zinc oxide nanomaterials are:

[0089] Step 1-1: Weigh 35 parts of one of zinc nitrate, zinc sulfate or zinc acetate by mass and put it into a flask, and add 65 parts of deionized water and stir well to dissolve.

[0090] Step 1-2: Add 45 parts of a mixture of one or several of lanthanum chloride heptahydrate, gadolinium nitrate hexahydrate or cerium chloride heptahydrate to the flask and stir evenly.

[0091] Step 1-3: Add 25 parts of polytetramethylsilane into the flask, set the temperature at 70 °C, and continue stirring for 5 hours.

[0092] Step 1-4: Then add one of 25 parts of ammonia water, urea, ammonium carbonate or sodium hydroxide into the solution, and continue stirring for 5 hours.

[0093] Step 1-5: After the reaction ends, filter the suspension in the flask by suction filtration, dry the obtained solid substance at 80 °C, then put it into a muffle furnace at 1000 °C and calcine for 4 hours, take it out after natural cooling, and it is the rare earth-doped zinc oxide nanomaterial powder.

[0094] Use an organic weak acid compound as the raw material to prepare the precursor, cyanuric acid as the linking component, deionized water as the solvent, obtain the intermediate buffer solution through a reflux reaction at 100 °C, then add the rare earth nitrate hexahydrate compound or rare earth chloride compound into the buffer solution, mix and perform ultrasonic treatment, slowly add the alkaline precipitation solution under the condition of 70 °C to adjust the reaction environment, and obtain a nanometer particle dispersion liquid containing rare earth lanthanum element or cerium element at pH = 11, so as to control the morphology and size of the material. Then, remove the excess organic matter and impurities through drying treatment and high-temperature calcination, and at the same time, obtain the final rare earth-doped zinc oxide nanomaterial with a lamellar shape through calcination at a specified temperature.

[0095] Furthermore, the preparation method of the water-based nano-functional slurry is as follows:

[0096] Among them, weigh the rare earth-doped zinc oxide nanomaterial and deionized water by mass, mix them evenly, then add a dispersant, and perform multi-stage grinding and dispersion evenly in a sand mill to obtain the water-based nano-functional slurry, and the particle size of the slurry is 100 nm.

[0097] Among them, the mass ratio of the rare earth-doped zinc oxide nanomaterial: deionized water: dispersant is 15:65:0.6.

[0098] Among them, the dispersant is one or a mixture of several of cetyltrimethylammonium bromide, polyvinylpyrrolidone, modified styrene maleic acid copolymer solution, modified polymer block copolymer, and high molecular weight silane copolymer containing a pigmentophilic group.

[0099] Specifically, use the sand grinding method to further process the material to achieve the purpose of reducing the particle size. Add the calcined rare earth nano-filler into a certain amount of solvent according to a solid content concentration of 20%, the solvent uses deionized water or organic solvents such as ethanol and ethylene glycol, and add 0.6% of sodium dodecylbenzenesulfonate or cetyltrimethylammonium chloride to play an auxiliary dispersion role, and use a Langling sand mill to sand grind for 8 h to obtain a nano-level rare earth nano-filler slurry suspension with a particle Dv90 of 100.

[0100] Steps for manufacturing the glove body 1 in the present invention: Weigh a certain amount of rare earth nano filler slurry suspension according to an addition amount of 2% of the rare earth nano filler slurry suspension, add it to the rubber latex, and stir well to make it evenly mixed. Then prepare a mold in a specific human hand shape made of aluminum or ceramic. Thoroughly clean the mold, remove any residues or impurities that may affect the product quality, and then immerse the mold in a coagulant and dry it. The coagulant can help the liquid latex adhere to the mold. After the mold is treated with the coagulant and dried, it will enter the liquid latex pool. The latex mixed with the rare earth material reacts with the coating on the mold, forms a gel-like state, and tightly adheres to the mold. The temperature of the latex and the dipping speed need to be strictly controlled in this step. Then the rubber glove will be dried and shaped for 10 minutes, and then coated with a smooth coating, and then vulcanized at 110°C for 30 minutes to obtain the glove body 1.

[0101] Example 3:

[0102] Please refer to FIGS. 1-7. A medical rare earth glove for preventing sharp object injuries includes a glove body 1 produced from latex added with a water-based nano-functional slurry. A hollow rubber tube 3 is provided at the cuff position of the glove body 1. The hollow rubber tube 3 is fixed to the cuff position of the glove body 1 by means of adhesion. A locking assembly 2 is hermetically connected to the back of the glove body 1. The locking assembly 2 includes a cylinder 21. A circular tube 23 for air extraction and inflation is provided inside the cylinder 21. The circular tube 23 communicates with an air vent 25 and the hollow rubber tube 3. The air vent 25 is located inside the glove body 1. While injecting the gas in the circular tube 23 into the hollow rubber tube 3, the circular tube 23 inhales the air inside the glove body 1 into the circular tube 23 by means of the air vent 25.

[0103] Specifically, in the present invention, by using latex added with a water-based nano-functional slurry to produce the glove body 1, the puncture resistance of the glove can be significantly improved, and the risk of infection on the hands of medical staff can be reduced. By extracting the air inside the glove body 1 through the circular tube 23 and at the same time delivering the gas in the circular tube 23 into the hollow rubber tube 3, this not only makes the hollow rubber tube 3 expand and closely adhere to the wrist of the medical staff, making the glove body 1 more stable when worn, but also evacuates the air between the glove body 1 and the hand of the medical staff, making the glove body 1 more closely adhere to the hand and improving the perception ability of the hand.

[0104] Furthermore, a knob 24 is rotatably provided inside the cylinder 21. The bottom of the knob 24 is clamped inside the cylinder 21. The bottom of the knob 24 is connected to a plunger 26 through a connecting rod 241. A circular cavity 231 is provided inside the circular tube 23. The plunger 26 is slidably provided inside the circular cavity 231. A partition 233 is fixedly connected inside the circular cavity 231. One side of the partition 233 communicates with the air vent 25, and the other side of the partition 233 communicates with the hollow rubber tube 3.

[0105] Specifically, referring to Figure 5 , the bottom of the knob 24 is stuck inside the cylinder 21 and cannot be pulled outwards. Referring to Figure 6 , the top of the connecting rod 241 is fixedly connected to the bottom of the knob 24, the other end of the connecting rod 241 is fixedly connected to the plunger 26, and the connecting rod 241 is slidably arranged in the guiding groove 232. The guiding groove 232 is a rectangular groove opened on the circular ring tube 23, and the guiding groove 232 communicates with the circular ring cavity 231 to limit the movement range of the connecting rod 241. When the knob 24 is turned, the plunger 26 is driven to slide in the circular ring cavity 231, thereby changing the amount of gas in the glove body 1 and the hollow rubber tube 3.

[0106] Furthermore, the bottom of the cylinder 21 is threadedly connected with a bottom plate 22, and the bottom plate 22 is adhesively bonded to the back of the glove body 1. A circular hole 234 is opened on one side of the circular ring tube 23 close to the ventilation member 25. After passing through the glove body 1 and the bottom plate 22, the ventilation member 25 is inserted into the circular hole 234 to be hermetically connected to the circular ring tube 23. The ventilation member 25 includes a cushion plate 251. The top of the cushion plate 251 is fixedly connected with a first connecting pipe 252. A sealing ring 253 is fixedly sleeved on the outside of the first connecting pipe 252. The top of the first connecting pipe 252 is fixedly connected with a hollow frustum tube 254. Two rectangular grooves 255 are opened on the hollow frustum tube 254. The opening of the rectangular grooves 255 provides space for the deformation of the hollow frustum tube 254. The diameter dimension of the bottom of the hollow frustum tube 254 is larger than the diameter dimension of the top of the first connecting pipe 252, which enables the hollow frustum tube 254 to be clamped in the circular ring cavity 231 after passing through the circular hole 234. Four air inlets 2511 are opened on the cushion plate 251, and the four air inlets 2511 communicate with the inner cavity of the circular ring tube 23 through the first connecting pipe 252. The setting of the cushion plate 251 enables a gap to exist between the glove body 1 and the back of the staff, facilitating the suction of the air in the glove body 1 into the circular ring tube 23.

[0107] Specifically, referring to Figure 4 , by setting the cylinder 21 and the bottom plate 22 to be threadedly connected, it is convenient to install parts such as the knob 24 and the circular ring tube 23 inside the cylinder 21. Referring to Figure 1 and Figure 6 , after the bottom plate 22 is adhesively bonded to the back of the glove body 1, the hollow frustum tube 254 and the first connecting pipe 252 are passed through the small holes opened on the glove body 1 from the inside of the glove body 1 and then inserted into the circular hole 234. The hollow frustum tube 254 squeezes the circular hole 234. Under the action of force, the hollow frustum tube 254 deforms and passes through the circular hole 234. Subsequently, the hollow frustum tube 254 resumes deformation and clamps the hollow frustum tube 254 in the circular ring cavity 231. At this time, the cushion plate 251 and the bottom plate 22 tightly clamp the back of the glove body 1 to ensure the sealing performance, and the sealing ring 253 is squeezed and deformed to be clamped in the circular hole 234, making the circular ring cavity 231 sealed.

[0108] Further, a second connecting pipe 27 is fixedly connected to the side surface of the circular ring pipe 23, and a third connecting pipe 31 is fixedly connected to the hollow rubber pipe 3. The third connecting pipe 31 is inserted into the second connecting pipe 27, so that the inner cavity of the hollow rubber pipe 3 is communicated with the inner cavity of the circular ring pipe 23.

[0109] Specifically, referring to Figure 3 and Figure 6 , the outer side of the top of the third connecting pipe 31 is made of soft rubber material. When the third connecting pipe 31 is inserted into the second connecting pipe 27 through the hole opened on the second connecting pipe 27 by extrusion, the inner cavity of the third connecting pipe 31 is communicated with the inner cavity of the circular ring pipe 23. And when the third connecting pipe 31 extrudes the hole on the second connecting pipe 27, the surface of the third connecting pipe 31 deforms and is clamped in the second connecting pipe 27, ensuring the sealing performance between the third connecting pipe 31 and the second connecting pipe 27.

[0110] Further, referring to Figures 1 to 7 , first put the glove body 1 on the hand, referring to Figure 3 and Figure 6 , then turn the knob 24 counterclockwise. The knob 24 drives the connecting rod 241 to rotate counterclockwise, and the plunger 26 slides counterclockwise in the circular ring cavity 231, so that the plunger 26 squeezes the gas in the circular ring cavity 231 into the hollow rubber pipe 3. At the same time, a negative pressure is formed on one side of the circular hole 234 opened in the circular ring cavity 231, and the air in the glove body 1 is sucked into the circular ring cavity 231. This not only makes the hollow rubber pipe 3 expand and closely adhere to the wrist of the medical staff, making the glove body 1 more stable when worn, but also evacuates the air between the glove body 1 and the hand of the medical staff, making the glove body 1 more closely adhere to the hand and improving the perception ability of the hand.

[0111] Further, a preparation method of a medical rare earth glove for preventing sharp object injuries, the steps included in the method are as follows:

[0112] Step 1: Prepare rare earth-doped zinc oxide nanomaterials,

[0113] Step 2: Prepare a water-based nano-functional slurry,

[0114] Step 3: Add the water-based nano-functional slurry to the latex used for the production of conventional gloves and stir, so that the water-based nano-functional slurry is uniformly and stably dispersed in the latex, and then produce according to the conventional production process of latex gloves.

[0115] Step 4: Set the locking assembly 2 and the hollow rubber pipe 3 at the position of the glove cuff.

[0116] In the present invention, the steps of the preparation method of the rare earth-doped zinc oxide nanomaterials are:

[0117] Step 1-1: Weigh 45 parts by mass of one of zinc nitrate, zinc sulfate, or zinc acetate and place it in a flask. Add 55 parts of deionized water and stir well to dissolve.

[0118] Step 1-2: Add 55 parts of a mixture of one or more of lanthanum chloride heptahydrate, gadolinium nitrate hexahydrate, or cerium chloride heptahydrate to the flask and stir evenly.

[0119] Step 1-3: Add 35 parts of polytetramethylsilane to the flask, set the temperature to 80 °C, and continue stirring for 3 hours.

[0120] Step 1-4: Then add 30 parts of one of ammonia water, urea, ammonium carbonate, or sodium hydroxide to the solution and continue stirring for 3 hours.

[0121] After the reaction is completed, filter the suspension in the flask by suction filtration. Dry the obtained solid material at 100 °C, then place it in a muffle furnace at 1200 °C and calcine for 2 hours. Take it out after natural cooling, and it is the rare earth-doped zinc oxide nanomaterial powder.

[0122] Using an organic weak acid compound as the raw material to prepare the precursor, cyanuric acid as the linking component, and deionized water as the solvent, obtain an intermediate buffer solution through a reflux reaction at 100 °C. Then add a rare earth nitrate hexahydrate compound or a rare earth chloride compound to the buffer solution, mix and perform ultrasonic treatment. Slowly add a basic precipitation solution under the condition of 80 °C to adjust the reaction environment, and obtain a dispersion of rare earth lanthanum element or cerium element-containing nanoparticles at pH = 11, thereby controlling the morphology and size of the material. Then, remove the excess organic matter and impurities through drying treatment and high-temperature calcination. At the same time, obtain the final rare earth-doped zinc oxide nanomaterial with a lamellar structure by calcining at a specified temperature.

[0123] Furthermore, the preparation method of the water-based nano-functional slurry is as follows:

[0124] Among them, weigh the rare earth-doped zinc oxide nanomaterial and deionized water by mass, mix them evenly, then add a dispersant, and perform multi-stage grinding and dispersion in a sand mill to obtain a water-based nano-functional slurry with a particle size of 100 nm.

[0125] Among them, the mass ratio of the rare earth-doped zinc oxide nanomaterial: deionized water: dispersant is 10:60:1.

[0126] Among them, the dispersant is one or a mixture of several of cetyltrimethylammonium bromide, polyvinylpyrrolidone, a modified styrene maleic acid copolymer solution, a modified polymer block copolymer, and a high molecular weight silane copolymer containing a pigmentophilic group.

[0127] Specifically, the material is further processed by sanding to achieve the purpose of reducing the particle size. The calcined rare earth nano-fillers are added to a certain amount of solvent at a solid content concentration of 40%. The solvent is deionized water or an organic solvent such as ethanol or ethylene glycol, and 1% of sodium dodecylbenzenesulfonate or cetyltrimethylammonium chloride is added to play an auxiliary dispersion role. The material is sanded with a Langling sand mill for 10 hours to obtain a nano-level rare earth nano-filler slurry suspension with a particle Dv90 of 100 nm.

[0128] In the present invention, the manufacturing steps of the glove body 1 are as follows: Weigh a certain amount of rare earth nano-filler slurry suspension according to an addition amount of 2% of the rare earth nano-filler slurry suspension, and add it to the rubber latex, and stir well to make it evenly mixed. Then prepare a mold in a specific human hand shape made of aluminum or ceramic, clean the mold thoroughly, and remove any residues or impurities that may affect the product quality. After that, immerse the mold in a coagulant and dry it. The coagulant can help the liquid latex adhere to the mold. After the mold is treated with the coagulant and dried, it will enter the liquid latex pool. The latex mixed with the rare earth material reacts with the coating on the mold, forming a gel-like substance and tightly adhering to the mold. The temperature of the latex and the dipping speed need to be strictly controlled in this process. Then the rubber glove will be dried and shaped for 10 minutes, and then coated with a smooth coating, and then vulcanized at 110 °C for 30 minutes to obtain the glove body 1.

[0129] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
