Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a hand protection device for intravenous injection. Background Art

[0002] Intravenous injection is one of the most common treatment methods in modern medicine, and is widely used in scenarios such as drug delivery, nutritional support, and blood transfusion. However, during the intravenous injection process, the needle needs to be adjusted and touched frequently, which may cause wear and tear on the hands of medical staff; and may also cause the spread of infection to the hands.

[0003] In the prior art, gloves are usually used to provide protection for the hands, which has certain limitations. Specifically, these gloves usually adopt an integrated design, cannot provide specific protection for different parts, and have poor flexibility. For example, fingers require higher flexibility for fine manipulation, while the palms require thicker cushioning to resist pressure and friction.

[0004] In summary, how to solve the problem of affecting operational flexibility in the prior art devices using integrated gloves to protect the hands has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a hand protection device for intravenous injection. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a hand protection device for intravenous injection. The finger cuff and the palm pad are designed independently so that each part can be adjusted according to actual needs. The appropriate size can be selected according to the size of the individual's hand, or the thickness can be increased for specific fingers to improve the protection level of sensitive areas, thereby increasing the flexibility of wearing.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a hand protection device for intravenous injection, comprising a medical glove, a palm pad and a plurality of finger sleeves, the medical glove having a wrist opening, the finger sleeves being worn on the fingers, and the palm pad being worn on the palm.

[0007] The finger sleeves and palm rest are made of elastic material.

[0008] The technical principles of the above scheme are as follows:

[0009] By wearing finger sleeves and palm pads on the hands of medical staff, since both the finger sleeves and palm pads are made of elastic materials, they can be worn on the hands of different medical staff to meet the personalized needs of medical staff of different body shapes. In addition, this elastic material can effectively absorb impact force without affecting the flexibility of the hands, effectively reducing the wear of external instruments on the hands. After the finger sleeves and palm pads are worn, medical gloves are used to provide an outer layer of protection, effectively isolating external chemicals, etc., to form a multi-level protection effect.

[0010] The above scheme has the following beneficial effects:

[0011] 1. The present invention provides additional cushioning and protection for fingers and palms through the design of finger sleeves and palm pads; because they are made of elastic materials, they can effectively absorb impact without affecting the flexibility of the hands, reducing the wear of external instruments on the hands. The use of medical gloves not only increases the overall protection level, but also plays an isolation role to prevent chemicals or biological contaminants from directly contacting the skin.

[0012] 2. The present invention independently designs the finger sleeve and the palm pad, so that each part can be adjusted according to actual needs; the appropriate size can be selected according to the size of the individual hand, or the thickness can be increased for specific fingers to improve the protection level of sensitive areas, thereby increasing the flexibility of wearing. In addition, this separate design allows a more precise fit to the curve of the hand, thereby ensuring a good touch and grip.

[0013] 3. The present invention realizes multi-level protection for the hands through the design of multi-layer materials and structures; the elastic materials of the finger sleeves and palm pads have a certain degree of flexibility, which can provide flexible support for the hands and reduce the risk of hand wear. At the same time, these materials also have good isolation properties, which can effectively block the invasion of harmful substances and protect the health of the hands.

[0014] Furthermore, the elastic material is selected from one or more of silicone, latex, PVC, nitrile rubber, chloroprene rubber, PU and TPE; and the finger sleeves are provided with a plurality of air holes along their circumferences.

[0015] Beneficial effects: The elastic material has good elasticity, wear resistance and corrosion resistance, so that the protective device can adapt to the hand movements, provide a comfortable wearing experience, and effectively isolate harmful substances to protect the hands from harm. The design of the air holes allows the fingers to maintain good air circulation when wearing the finger sleeves, reduces the accumulation of sweat and the dampness of the fingers, and improves the wearing comfort.

[0016] Furthermore, a finger ring is fixedly connected to the top of the palm pad, and the finger ring is used to be put on the finger.

[0017] Beneficial effects: The design of the finger ring can effectively fix the palm pad on the medical staff's finger to prevent the palm pad from sliding or shifting during the operation, thereby improving the stability and accuracy of the operation.

[0018] Furthermore, it also includes a wearing assembly for wearing medical gloves, and the wearing assembly includes a wearing box; an opening is opened on the top of the wearing box, and a mounting assembly for tightening and releasing the wrist opening is provided at the opening.

[0019] A pump assembly for pumping gas is fixedly connected to the outer wall of the wearing box, and the pump assembly is electrically connected to a controller, which is used to control the opening and closing of the pump assembly; the input end of the pump assembly is connected to the inside of the wearing box, and the output end of the pump assembly is connected to the outside of the wearing box.

[0020] Beneficial effect: The wrist of the medical glove is placed on the opening of the wearing box through the installation component, and it is in a tightened state. Since the outer wall of the wearing box is fixedly connected with a pump component, and the input end of the pump component is connected to the inside of the wearing box, the air inside the wearing box can be pumped out through the pump component, and the inside of the wearing box is in a negative pressure environment after being pumped out. At this time, since the pressure environment inside the medical glove is different from that of the wearing box, the negative pressure environment generated in the wearing box can attract the medical glove and expand. After the medical glove is expanded, the medical staff can easily place their hands in the medical glove.

[0021] Then, the wrist of the medical glove is released through the installation component, so that the outside air enters the wearing box, and the operation of the pump component is turned off; the negative pressure environment inside the wearing box is released, so that the medical glove can be quickly rebounded through its own elasticity, so that the medical glove can be quickly worn on the hands of medical staff. Through this automated wearing process, the wearing time can be effectively shortened, the work efficiency of medical staff can be improved, and the damage of medical gloves caused by manual operation can be reduced, thereby helping to reduce the cost of using medical gloves.

[0022] Furthermore, the installation assembly includes a fixed disk, a rotating disk and an elastic ring; the fixed disk is fixedly connected to the top of the wearing box above the opening, the rotating disk is located inside the fixed disk and rotates with the inner wall of the fixed disk; both the fixed disk and the rotating disk are provided with connecting ports connected to the opening, and the fixed disk is also provided with a driving assembly for driving the rotating disk to rotate.

[0023] The top of the fixed disk is provided with an inclined groove along its circumference, and a moving rod is slidably and rotatably fitted in the inclined groove; the bottom of the moving rod is fixedly connected with an isosceles pentagonal special-shaped block, the isosceles sides of adjacent special-shaped blocks are slidably fitted with each other, and the bottom of the special-shaped blocks is fixedly connected with a slider; the rotating disk is provided with a rhombus groove along its circumference, and the sliders are located in the rhombus groove and slidably fitted with the rhombus groove; the top of the special-shaped block is fixedly connected with a connecting rod, the top of the connecting rod is fixedly connected with an elastic ring, and the wrist opening is sleeved on the outer wall of the elastic ring.

[0024] Beneficial effect: The driving assembly drives the rotating disk to rotate. Since the rotating disk has a rhombus groove along its circumference, a slider is slidably fitted in the rhombus groove, and a special-shaped block is fixedly connected to the top of the slider, when the rotating disk rotates, its rhombus groove rotates accordingly, so that the slider inside the rhombus groove drives the special-shaped block to rotate. In this process, the inclined groove provides a limiting function, so that the special-shaped block can rotate stably.

[0025] Since the special-shaped blocks are in the shape of isosceles pentagons, the isosceles sides of adjacent special-shaped blocks slide and cooperate with each other, so during the rotation of the special-shaped blocks, the polygonal structure formed by the sliding of the isosceles sides can be enlarged or reduced. Since the tops of the special-shaped blocks are fixedly connected to connecting rods, and the connecting rods are fixedly connected to elastic rings, during the enlargement or reduction of the polygonal structure, the elastic rings can be supported or shrunk. By setting the wrist of the medical glove on the elastic ring, when the elastic ring is supported, the wrist can be tightened, and when tightened, the wrist will be in close contact with the elastic ring, so that the connection position is in a sealed state, and when the elastic ring shrinks, the wrist is released by its own elastic force.

[0026] Furthermore, the driving assembly includes a gear, an arc-shaped gear ring and a rotating part for rotating the gear, and the controller is used to control the operation of the rotating part; the rotating part is fixedly connected to the inner wall of the fixed disk, and the output shaft of the rotating part is coaxially fixedly connected to the gear; the arc-shaped gear ring is embedded and installed at the bottom of the rotating disk, and the gear and the arc-shaped gear ring are meshed with each other.

[0027] Beneficial effect: the gear is driven to rotate by the rotating part. Since the rotating disk is located in the fixed disk for rotation, the arc-shaped gear ring is fixedly connected to the bottom of the rotating disk, and the gear is meshed with the arc-shaped gear ring. Therefore, when the gear rotates, the arc-shaped gear ring can rotate accordingly, and the arc-shaped gear ring drives the rotating disk to rotate, so that each component of the device can be automatically controlled.

[0028] Furthermore, a protection box is fixedly connected to the top of the wearing box, and an entry is opened on the top of the protection box; a cover plate is hinged on the top of the entry, and a torsion spring is provided at the hinge between the cover plate and the protection box.

[0029] Beneficial effects: The design of the protective box forms an additional space, providing a further physical barrier to effectively isolate external dust and bacteria from entering the wearing box. The design of the cover can further make the environment inside the protective box more sealed, further improving the practicality of the device. The torsion spring has a strong elastic recovery force. When the cover is opened, the torsion spring can restore the cover to the closed position, further increasing the portability of the device.

[0030] Furthermore, a sealing ring is fixedly connected at the connection point between the wearing box and the pump assembly.

[0031] Beneficial effect: Through the design of the sealing ring, the wearing box and the external channel are further isolated, thereby ensuring that the pump assembly can stably suck out the gas inside the wearing box, thereby improving the efficiency of the device operation.

[0032] Furthermore, an air pressure sensor is fixedly connected to the inner wall of the wearing box; the controller is used to receive and store the air pressure signal of the air pressure sensor, and control the operation of the pump assembly based on the air pressure signal.

[0033] Beneficial effects: By real-time monitoring of air pressure and dynamically adjusting the working state of the pump assembly, it is ensured that the inside of the wearing box is always maintained in a stable negative pressure environment. It can effectively reduce the excessive stretching or damage of medical gloves caused by excessive suction, and further reduce the cost of using medical gloves.

[0034] Furthermore, an ultraviolet lamp is fixedly connected to the inner wall of the protection box, and the controller is used to control the operation of the ultraviolet lamp.

[0035] Beneficial effects: The use of ultraviolet light can keep the inside of the protective box sterile, further ensuring the sterility of medical staff when wearing medical gloves. The ultraviolet light can be automatically started according to the preset time for periodic disinfection to ensure the sterility of the internal environment of the protective box before and after each use.

[0036] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1:

[0045] As attached Figure 1As shown: a hand protection device for intravenous injection, including a medical glove 16, a palm pad 2 and a plurality of finger sleeves 1, the medical glove 16 has a wrist opening, the finger sleeves 1 are used to be worn on the fingers of medical staff, and the palm pad 2 is used to be worn on the palms of medical staff.

[0046] The finger sleeve 1 and the palm pad 2 are both made of elastic material, and the elastic material is selected from one or more of silicone, latex, PVC, nitrile rubber, chloroprene rubber, PU and TPE. In this embodiment, the elastic material is silicone. After the medical staff puts on the finger sleeve 1 and the palm pad 2 according to the needs, they put the medical gloves 16 on the hands from the wrist.

[0047] The finger sleeve 1 is provided with a plurality of ventilation holes along its circumference. The design of the ventilation holes allows the fingers to maintain good air circulation when wearing the finger sleeve 1, reduces the accumulation of sweat and the damp feeling of the fingers, and improves the wearing comfort.

[0048] A finger ring is integrally formed on the top of the palm pad 2, and the finger ring is used to be put on the finger of the medical staff. The design of the finger ring can effectively fix the palm pad 2 on the finger of the medical staff, prevent the palm pad 2 from sliding or shifting during the operation, thereby improving the stability and accuracy of the operation.

[0049] The specific implementation process is as follows: by wearing the finger sleeve 1 and the palm pad 2 on the hands of medical staff, since the finger sleeve 1 and the palm pad 2 are both made of elastic material, the finger sleeve 1 and the palm pad 2 can be worn on the hands of different medical staff to meet the personalized needs of medical staff of different body shapes. In addition, this elastic material has good elasticity, wear resistance and corrosion resistance, so that the finger sleeve 1 and the palm pad 2 can adapt to the hand movement, can effectively absorb the impact force without affecting the flexibility of the hand, and thus effectively reduce the wear of the hand by external instruments.

[0050] After the finger sleeves 1 and the palm pads 2 are worn, the medical gloves 16 are used to provide outer protection, effectively isolating external chemical substances, etc., to form a multi-level protection effect.

[0051] The present invention provides additional cushioning and protection for the fingers and palms through the design of the finger sleeve 1 and the palm pad 2; because they are made of elastic materials, they can effectively absorb impact without affecting the flexibility of the hand and reduce the wear of external instruments on the hand. The use of medical gloves 16 not only increases the overall protection level, but also plays an isolation role to prevent chemical substances or biological contaminants from directly contacting the skin.

[0052] By designing the finger sleeve 1 and the palm pad 2 independently, each part can be adjusted according to actual needs; the appropriate size can be selected according to the size of the individual hand, or the thickness can be increased for specific fingers to improve the protection level of sensitive areas, thereby increasing the flexibility of wearing. In addition, this separate design allows a more precise fit to the curve of the hand, thus ensuring a good touch and grip.

[0053] Through the design of multi-layer materials and structures, multi-level protection for hands is achieved; the elastic materials of the finger sleeve 1 and the palm pad 2 have a certain degree of flexibility, which can provide flexible support for the hands and reduce the risk of hand wear. At the same time, these materials also have good isolation properties, which can effectively block the invasion of harmful substances and protect the health of hands.

[0054] Embodiment 2:

[0055] As attached Figure 2-Figure 5 As shown, the difference from the above embodiment is that it also includes a wearing component for wearing medical gloves 16, and the wearing component includes a wearing box 3; the wearing box 3 has an opening at the top, and a mounting component for tightening and releasing the wrist opening is provided at the opening.

[0056] The outer wall of the wearing box 3 is fixedly connected with a pump assembly for pumping gas by screws. In this embodiment, the pump assembly is an air pump 4, and the air pump 4 is electrically connected to a controller, which is used to control the opening and closing of the air pump 4; the input end of the air pump 4 is connected to the inside of the wearing box 3, and the output end of the air pump 4 is connected to the outside of the wearing box 3.

[0057] The mounting assembly includes a fixed disk 5, a rotating disk 6 and an elastic ring 11; the fixed disk 5 is fixedly connected to the top of the wearing box 3 with screws, and the rotating disk 6 is located inside the fixed disk 5 and rotates with the inner wall of the fixed disk 5; both the fixed disk 5 and the rotating disk 6 are provided with connecting ports connected to the opening, and a driving assembly for driving the rotating disk 6 to rotate is also provided on the fixed disk 5.

[0058] The top of the fixed disk 5 is provided with an inclined groove along its circumference, and a moving rod 7 is slidably and rotatably fitted in the inclined groove; the bottom of the moving rod 7 is fixedly connected with an isosceles pentagonal special-shaped block 8 by screws, and the isosceles sides of adjacent special-shaped blocks 8 are slidably fitted with each other, and the bottom of the special-shaped block 8 is fixedly connected with a slider 9 by screws; a rhombus groove is provided on the rotating disk 6 along its circumference, and the sliders 9 are all located in the rhombus groove and slidably fit with the rhombus groove; the top of the special-shaped block 8 is fixedly connected with a connecting rod 10 by screws, and the top of the connecting rod 10 is fixedly bonded with an elastic ring 11, and the wrist opening is sleeved on the outer wall of the elastic ring 11.

[0059] The driving assembly includes a gear 12, an arc-shaped gear ring and a rotating part for rotating the gear 12. In this embodiment, the rotating part is a rotating motor 13, and the controller is used to control the operation of the rotating motor 13; the rotating motor 13 is screw-fixedly connected to the inner wall of the fixed disk 5, and the output shaft of the rotating motor 13 is coaxially fixedly engaged with the gear 12; the arc-shaped gear ring is embedded and installed at the bottom of the rotating disk 6, and the gear 12 and the arc-shaped gear ring are meshed with each other.

[0060] The specific implementation process is as follows: the gear 12 is driven to rotate by rotating the motor 13. Since the rotating disk 6 is located in the fixed disk 5 for rotation, the arc-shaped gear ring is embedded and installed at the bottom of the rotating disk 6, and the gear 12 is meshed with the arc-shaped gear ring; therefore, when the gear 12 rotates, the arc-shaped gear ring can rotate accordingly, and the arc-shaped gear ring drives the rotating disk 6 to rotate.

[0061] Combination Figure 5 As shown, since the rotating disk 6 is provided with a diamond-shaped groove along its circumference, a slider 9 is slidably fitted in the diamond-shaped groove, and a special-shaped block 8 is fixedly connected to the top of the slider 9 by screws, when the rotating disk 6 rotates, its diamond-shaped groove rotates accordingly, so that the slider 9 inside the diamond-shaped groove drives the special-shaped block 8 to rotate. In this process, the inclined groove provides a limiting function, so that the special-shaped block 8 can rotate stably.

[0062] Since the special-shaped block 8 is an isosceles pentagon, the isosceles sides of adjacent special-shaped blocks 8 slide with each other, so during the rotation of the special-shaped block 8, the polygonal structure formed by the sliding of the isosceles sides can be enlarged or reduced. Figure 5 For example, when the rotating disk 6 drives the diamond groove to rotate clockwise, it drives the special-shaped block 8 to slide and rotate to the right, and the polygonal structure is enlarged. Conversely, when the rotating disk 6 drives the diamond groove to rotate counterclockwise, the special-shaped block 8 can slide and rotate to the left, so that the polygonal structure is reduced.

[0063] Since the top of the special-shaped block 8 is fixedly connected with a connecting rod 10 by screws, and the connecting rod 10 is fixedly bonded to the elastic ring 11, the elastic ring 11 can be supported or contracted during the process of the polygonal structure being enlarged or reduced. By putting the wrist of the medical glove 16 on the elastic ring 11, when the elastic ring 11 is supported, the wrist can be tightened, and when tightened, the wrist will be in close contact with the elastic ring 11, so that the connection position is in a sealed state, and when the elastic ring 11 contracts, the wrist is released by its own elastic force.

[0064] Combination Figure 3As shown, the wrist opening is sleeved on the opening of the wearing box 3 by means of an elastic ring 11, and the elastic ring 11 is expanded to make the wrist opening in a tightened state. Since the outer wall of the wearing box 3 is fixedly connected with an air pump 4 by screws, and the input end of the air pump 4 is connected to the inside of the wearing box 3, the air inside the wearing box 3 can be pumped out by the air pump 4, and after the air is pumped out, the inside of the wearing box 3 is in a negative pressure environment. At this time, since the pressure environment inside the medical glove 16 is different from that of the wearing box 3, the negative pressure environment generated in the wearing box 3 can attract the medical glove 16 and expand it. After the medical glove 16 is expanded, the medical staff can easily place their hands in the medical glove 16.

[0065] Then, the wrist opening of the medical glove 16 is released by shrinking the elastic ring 11, so that the external air enters the wearing box 3, and the air pump 4 is turned off; so that the negative pressure environment inside the wearing box 3 is released, so that the medical glove 16 is quickly rebounded by its own elasticity, so that the medical glove 16 is quickly worn on the hand of the medical staff. Through this automated wearing process, the wearing time can be effectively shortened, the working efficiency of the medical staff can be improved, and the damage of the medical glove 16 caused by manual operation can be reduced, thereby helping to reduce the use cost of the medical glove 16.

[0066] Embodiment 3:

[0067] As attached Figure 2 As shown, the difference from the above embodiment is that the top of the wearing box 3 is fixedly connected with a protection box 14 by screws, and an entrance is opened on the top of the protection box 14; a cover plate 15 is hinged on the top of the entrance, and a torsion spring is provided at the hinge.

[0068] The specific implementation process is as follows: through the design of the protection box 14, an additional space is formed to provide a further physical barrier, effectively isolating external dust and bacteria from entering the wearing box 3. The design of the cover 15 can further make the environment inside the protection box 14 more sealed, so that the practicality of the device is further improved. In addition, the torsion spring has a strong elastic restoring force. When the cover 15 is opened, the torsion spring can restore the cover 15 to the closed position, further increasing the portability of the device.

[0069] Embodiment 4:

[0070] The difference from the above embodiment is that a sealing ring is fixedly bonded at the connection point between the wearing box 3 and the air pump 4.

[0071] The specific implementation process is as follows: through the design of the sealing ring, the wearing box 3 is further isolated from the external channel, thereby ensuring that the air pump 4 can stably suck out the gas inside the wearing box 3, thereby improving the efficiency of the device operation.

[0072] Embodiment 5:

[0073] The difference from the above embodiment is that an air pressure sensor is also fixedly bonded to the inner wall of the wearing box 3; the controller is used to receive and store the air pressure signal of the air pressure sensor, and control the operation of the air pump 4 based on the air pressure signal.

[0074] The specific implementation process is as follows: by real-time monitoring of air pressure and dynamically adjusting the working state of the air pump 4, it is ensured that the inside of the wearing box 3 is always maintained in a stable negative pressure environment. This can effectively reduce the excessive stretching or damage of the medical gloves 16 caused by excessive suction, and further reduce the use cost of the medical gloves 16.

[0075] Embodiment 6:

[0076] The difference from the above embodiment is that an ultraviolet lamp is fixedly connected to the inner wall of the protection box 14 by screws, and the controller is used to control the operation of the ultraviolet lamp.

[0077] The specific implementation process is as follows: the ultraviolet lamp can be used to make the inside of the protective box 14 sterile, further ensuring the sterility of medical staff when wearing medical gloves 16. The ultraviolet lamp can be automatically started according to the preset time for periodic disinfection to ensure the sterility of the internal environment of the protective box 14 before and after each use.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
