Description

Technical Field

[0001] The invention belongs to the field of medical technology, and in particular is a pressure bandaging device based on clinical wound care. Background Art

[0002] In clinical wound care, pressure dressing is a common treatment method, which bandages the wound with bandages, gauze and other materials and promotes wound healing by applying a certain amount of pressure. Traditional pressure dressing devices often use bandages to repeatedly wrap to achieve the purpose of pressure. However, with the continuous advancement of medical technology and the increasing needs of patients, traditional pressure dressing devices have been unable to meet clinical needs.

[0003] The traditional bandage pressure dressing method has the problem of unreliable fixation, especially when the patient is active or the wound is located in a difficult-to-fix part, the bandage is easy to loosen or fall off, thus affecting the pressure effect. Due to the limited flexibility and adjustability of the bandage, it is difficult to ensure uniform and appropriate pressure on the wound. Excessive pressure may cause excessive pressure on the wound and affect blood circulation; too little pressure may not achieve the purpose of hemostasis and fixation of the wound. The traditional bandage pressure dressing method requires a lot of time and energy to wrap and fix, especially when the wound is large or irregular in shape, the operation is more cumbersome. In addition, it is also difficult to remove the bandage, which can easily cause discomfort and pain to the patient. The current pressure dressing device includes a squeeze box, but some patients may feel too strong a sense of pressure during use. The comfort, breathability and ease of operation of the traditional pressure dressing device still need to be improved.

[0004] In summary, the poor stability of the traditional bandage pressure dressing method has become a problem that the technicians in this field need to solve urgently. Therefore, it is necessary to propose a pressure dressing device based on clinical wound care. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a pressure bandage device based on clinical wound care, which improves the flexibility and stability of the pressure bandage method through an extrusion box and a multi-layer extruded tablet with adjustable extrusion position, extrusion force and temperature.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: A pressurized bandage device based on clinical wound care, comprising an extrusion box, a fixing assembly for fixing the extrusion box is provided on the extrusion box, a knob is rotatably connected to the top of the extrusion box, a controller is fixedly connected to the top of the knob, a ball screw penetrating the top of the extrusion box is fixedly connected to the bottom of the knob, a nut base is rotatably matched on the ball screw, an extrusion block is fixedly connected around the outer wall of the nut base, the extrusion block is slidably matched with the inner wall of the extrusion box, a plurality of batteries are detachably connected to the top of the extrusion block, a semiconductor chip and a pressure sensor are respectively fixedly connected to the bottom of the extrusion block, an extrusion tablet is detachably connected to the bottom of the extrusion box, and the pressure sensor, the battery and the semiconductor chip are all connected to the controller signal.

[0007] The following principles and beneficial effects are achieved by adopting the above scheme:

[0008] Basic principle: The extrusion box is a core component, and the two sides of its outer wall are fixedly connected with slides, which are used to slide with the elastic fixing belt, so that the elastic fixing belt can be flexibly adjusted according to the position and size of the wound. The top of the extrusion box is rotatably connected with a knob, and the top of the knob is fixedly connected with a controller to control the working state of the entire device. The bottom of the knob is fixedly connected with a ball screw that runs through the top of the extrusion box. The ball screw rotates with the nut base, and the nut base can be driven up and down by rotating the knob. The outer wall of the nut base is fixedly connected with an extrusion block, which slides with the inner wall of the extrusion box to ensure that the extrusion block remains stable during movement. Several batteries are detachably connected to the top of the extrusion block to provide power support for the entire device. The bottom of the extrusion block is fixedly connected with a semiconductor chip and a pressure sensor. The semiconductor chip is used to adjust the temperature in the extrusion box to meet the care needs of different wounds; the pressure sensor is used to monitor the pressure applied by the extrusion block to the wound in real time to ensure that the pressure is moderate. The bottom of the extrusion box is detachably connected with extrusion tablets, which can select appropriate drugs according to the wound condition to accelerate wound healing.

[0009] Beneficial effects:

[0010] 1. The present invention ensures that the extrusion block applies uniform and stable pressure to the wound by slidingly cooperating with the inner wall of the extrusion box and moving up and down by driving the knob and the ball screw, thereby avoiding the problem of the bandage being easily loosened or falling off in the traditional bandage pressure dressing method.

[0011] 2. The present invention can monitor and adjust the pressure applied by the extrusion block to the wound and the temperature in the extrusion box in real time through the cooperation of the controller, pressure sensor and semiconductor chip, thereby realizing intelligent control of pressurized bandage and improving nursing efficiency and quality.

[0012] 3. Compared with the traditional bandage pressure dressing method, the device of the present invention is easier and quicker to operate, and does not require a lot of time and energy to wrap and fix. Especially when the wound is large or irregular in shape, the operation is more convenient.

[0013] 4. The device of the present invention can flexibly adjust the pressure and temperature according to the wound condition and is easy to disassemble, so it can greatly reduce the patient's discomfort and pain during the pressure bandage process and improve the patient's comfort.

[0014] Furthermore, the extruded tablet comprises a capsule layer, a degradation layer and a contact layer which are fixedly connected in sequence from top to bottom.

[0015] Beneficial effects: The three-layer extruded tablet design enables the device to be personalized according to the needs of different wounds. For example, the type and release amount of the drug can be changed by replacing the extruded capsules with different ingredients and dosages; the release rate and time of the drug can be controlled by adjusting the material and thickness of the degradation layer. This design greatly enhances the adaptability and flexibility of the device, enabling it to meet more diverse wound care needs.

[0016] Furthermore, a plurality of extruded capsules for sustained release of different drugs are embedded in the capsule layer, and the extruded capsules 13 are all loaded with drugs, including one or more of antibiotics, analgesics and anti-inflammatory drugs.

[0017] Beneficial effects: Different wound types and patient conditions require different drug treatment plans. The device provides squeeze capsules with multiple drugs, which can flexibly select and combine different drugs according to the specific needs and wound conditions of the patient. This personalized treatment method can ensure that patients get the treatment plan that best suits them, improving the targetedness and effectiveness of treatment. The design of the squeeze capsule achieves a sustained release effect of the drug, that is, the drug is gradually released into the wound in the squeeze capsule. This sustained release method can avoid sudden changes in drug concentration and reduce side effects and adverse reactions of the drug. At the same time, the sustained release effect can also ensure that the drug continues to work at the wound, improving the utilization rate and treatment effect of the drug.

[0018] Furthermore, the diameters of the several extrusion capsules are different, and the extrusion rupture pressure of the extrusion capsule with a larger diameter is smaller than the extrusion rupture pressure of the extrusion capsule with a smaller diameter.

[0019] Beneficial effects: By setting extrusion capsules of different diameters and corresponding to different extrusion breakage pressures, more precise drug release control can be achieved. During the pressurized bandage process, as the pressure increases, the extrusion capsules with large diameters and small breakage pressures will break first, releasing the drugs inside. As the pressure increases further, the extrusion capsules with small diameters and large breakage pressures will break and release the drugs. This design allows drug release to more accurately match the different stages and needs of wound care.

[0020] Furthermore, the degradation layer comprises a degradation block with a cavity, the degradation block is filled with biodegradable polymer material, the side walls of the degradation block are made of water-soluble film, and the degradation block is located in the drug flow track in the extruded capsule.

[0021] Beneficial effects: The biodegradable polymer material gradually degrades after contact with wound exudate and body fluids, which means it will not stay in the wound for a long time, thus avoiding secondary injuries or complications that may be caused by long-term presence. This is crucial for wound healing and patient recovery. The gradual degradation process of the degradation layer also means that it will not cause continuous pressure or discomfort to the patient. As the degradation progresses, the patient can gradually feel the relief and comfort of the wound, which helps to improve patient acceptance and satisfaction.

[0022] Furthermore, the contact layer is made of non-woven fabric, and the contact layer 14 is provided with a plurality of through holes for ventilation and drug release.

[0023] Beneficial effects: The through-hole design allows the wound to maintain proper air permeability, which helps reduce the dampness and stuffiness of the wound and reduces the risk of infection. At the same time, the air permeability can also promote blood circulation around the wound, provide the wound with sufficient oxygen and nutrients, and thus accelerate the healing process of the wound. The through-hole not only helps with air permeability, but also ensures that the drug can be evenly released from the contact layer to the wound. After the capsule is squeezed and ruptured, the drug will penetrate into the wound surface through the through-hole to achieve uniform distribution of the drug. This uniform release method can improve the utilization rate and treatment effect of the drug, ensuring that the wound is treated comprehensively and effectively.

[0024] Furthermore, the fixing assembly includes a slide groove and an elastic fixing belt. The slide groove is fixedly connected to both sides of the outer wall of the extrusion box. The elastic fixing belts are slidably matched with the slide groove. Buckles for locking the elastic fixing belts are fixedly connected to both sides of the slide groove.

[0025] Beneficial effects: Through the cooperation of the chute and the elastic fixing belt, as well as the drive of the knob and the ball screw, the extrusion block can be precisely adjusted according to the position and size of the wound, greatly improving the flexibility of the pressure bandage. The buckle design enables the elastic fixing belt to be firmly locked on the chute and is not easy to loosen or fall off. This stability and reliability is crucial for the pressure bandage of the wound, which can ensure that the bandage device is always in the correct position and pressure, thereby effectively promoting wound healing.

[0026] Furthermore, an anti-slip layer is fixedly connected to the outer wall of the knob.

[0027] Beneficial effect: The design of the anti-slip layer can increase the friction between the knob and the user's fingers, preventing misoperation or knob falling off due to hand slipping during rotation.

[0028] Furthermore, a sealing layer is fixedly connected to the outer wall of the extrusion block close to the inner wall of the extrusion box.

[0029] Beneficial effects: The main function of the sealing layer is to ensure close contact between the extrusion block and the inner wall of the extrusion box, thereby effectively preventing the drug loaded in the extrusion capsule from leaking when it is not needed.

[0030] Furthermore, the heating and cooling surface of the semiconductor sheet faces the extruded tablet, and an extrusion sheet for bearing the extrusion force and conducting the temperature is fixedly connected to the heating and cooling surface.

[0031] Beneficial effects: The semiconductor chip, as a heating and cooling element, can accurately control the temperature of the extruded tablet according to the needs of wound care. By adjusting the working state of the semiconductor chip, the temperature of the extruded tablet can be controlled, thereby affecting the release rate and effect of the drug.

DETAILED DESCRIPTION

[0036] The following is further described in detail through specific implementation methods:

[0037] Example 1

[0038] Basically as attached Figure 1-3As shown: A pressure dressing device based on clinical wound care, including an extrusion box 1, a fixing assembly for fixing the extrusion box 1 is provided on the extrusion box 1, the fixing assembly includes a slide 7 and an elastic fixing belt 4, the slide 7 is fixedly connected to both sides of the outer wall of the extrusion box 1, and the elastic fixing belt 4 is slidably matched with the slide 7, characterized in that the slide 7 is fixedly connected to both sides of the outer wall of the extrusion box 1 by bolts, the elastic fixing belt 4 is slidably matched with the slide 7, the top of the extrusion box 1 is rotatably matched with a knob 3, and the outer wall of the knob 3 is fixedly connected with an anti-slip layer by bolts. The top of the knob 3 is fixedly connected with a controller 2 by bolts, the bottom of the knob 3 is fixedly connected with a ball screw 9 that penetrates the top of the extrusion box 1 by bolts, the ball screw 9 is rotatably matched with a nut base 8, the outer wall of the nut base 8 is surrounded and fixedly connected with an extrusion block 10 by bolts, the extrusion block 10 is slidably matched with the inner wall of the extrusion box 1, the top of the extrusion block 10 is detachably connected with a plurality of batteries 11, and the outer wall of the extrusion block 10 close to the inner wall of the extrusion box 1 is bonded with a sealing layer. The bottom of the extrusion block 10 is fixedly connected with a semiconductor chip 12 and a pressure sensor 18 by bolts.

[0039] The bottom of the extrusion box 1 is detachably connected with an extrusion tablet 5, and the extrusion tablet 5 includes a capsule layer 16, a degradation layer 15 and a contact layer 14 which are fixedly connected in sequence from top to bottom. A plurality of extrusion capsules 13 for sustained release of different drugs are embedded in the capsule layer 16, and the extrusion capsules 13 are loaded with drugs, including one or more of antibiotics, analgesics and anti-inflammatory drugs. The diameters of the plurality of extrusion capsules 13 are different, and the extrusion breakage pressure of the extrusion capsules 13 with a large diameter is less than the extrusion breakage pressure of the extrusion capsules 13 with a small diameter. The degradation layer 15 includes a degradation block with a cavity, and the degradation block is filled with a biodegradable polymer material. The side walls of the degradation block are made of a water-soluble film, and the degradation block is located in the drug flow track in the extrusion capsule 13.

[0040] The contact layer 14 is made of non-woven fabric and has a plurality of through holes 19 for ventilation and drug release.

[0041] The pressure sensor 18 , the battery 11 , and the semiconductor chip 12 are all connected to the controller 2 via signals.

[0042] Specific implementation steps:

[0043] First, clean and treat the patient's wound to ensure that the wound surface is clean and free of foreign matter. Install the squeeze tablet 5 at the bottom of the squeeze box 1 and ensure that it is firmly connected. Wrap the elastic fixing belt 4 around the wound and slide the elastic fixing belt 4 through the slide 7 to the appropriate position to prepare for subsequent fixation. Place the pressure dressing device above the wound to ensure that the contact layer 14 is in close contact with the wound.

[0044] Rotate the knob 3, and the extrusion block 10 moves downward through the transmission of the ball screw 9 and the nut base 8, so as to apply pressure to the extruded tablet 5. The controller 2 monitors the pressure of the extrusion block 10 on the extruded tablet 5 in real time through the pressure sensor 18 to ensure that the pressure is within a suitable range. When the extrusion block 10 applies sufficient pressure to the extruded tablet 5, the extrusion capsule 13 with a larger diameter will break first and release the drug. As time goes by, the pressure gradually increases, and the extrusion capsules 13 with smaller diameters will also break in turn, continuously releasing the drug. The water-soluble film and biodegradable polymer materials of the degradation block in the degradation layer 15 gradually degrade after contacting the wound exudate and body fluids, which helps the penetration of the drug and the healing of the wound. The through holes 19 on the contact layer 14 allow ventilation and the release of the drug, while maintaining a moist environment for the wound to promote healing.

[0045] The controller 2 continuously monitors the working state of the device, including the squeezing force and the drug release, through the semiconductor chip 12 and the pressure sensor 18. If the squeezing force needs to be adjusted, the position of the squeezing block 10 can be changed by rotating the knob 3, thereby adjusting the pressure on the squeezed tablet 5. The pressure bandage device is fixed above the wound using an elastic fixing band 4 to ensure that the device does not fall off or shift. When the wound is properly cared for and the drug is released, the elastic fixing band 4 can be loosened to remove the pressure bandage device.

[0046] During use, the integrity of the device and the remaining amount of the medicine are regularly checked. When the storage battery 11 is low on electricity or the extruded tablets 5 are exhausted, new storage batteries 11 and extruded tablets 5 are promptly replaced.

[0047] Example 2

[0048] Basically as attached Figure 2 As shown: The difference from the above embodiment is that buckles 6 for locking the elastic fixing belt 4 are fixedly connected to both sides of the slide groove 7 by bolts.

[0049] Specific implementation steps:

[0050] When the elastic fixing belt 4 slides to a proper position through the slide groove 7, the elastic fixing belt 4 is locked at a desired position by a locking mechanism of the buckle 6, such as the buckle 6, a button, etc., to prevent the squeeze box 1 from sliding or falling off.

[0051] Example 3

[0052] Basically as attached Figure 2 As shown: The difference from the above embodiment is that the heating and cooling surface of the semiconductor sheet 12 faces the extrusion tablet 5, and the heating and cooling surface is fixedly connected with an extrusion sheet 17 for bearing the extrusion force and conducting the temperature by bolts.

[0053] Specific implementation steps:

[0054] According to the wound condition, choose the appropriate cold compress or hot compress. Cold compress is usually used to reduce swelling, pain and inflammation, while hot compress helps promote blood circulation and muscle relaxation. The working mode of the semiconductor chip 12 is set by the controller 2 to achieve the effect of cold compress or hot compress. For cold compress, the semiconductor chip 12 should be set to cooling mode; for hot compress, it should be set to heating mode.

[0055] According to the sensitivity of the wound and the treatment requirements, the temperature setting of the semiconductor sheet 12 is adjusted to ensure that the temperature is within a safe and effective range. During the cold or hot compress process, the controller 2 will continuously monitor the temperature of the semiconductor sheet 12, the data of the pressure sensor 18, and the power of the battery 11.

[0056] If the temperature or pressure needs to be adjusted, the corresponding settings can be made through controller 2.

[0057] The above is only an embodiment of the present invention. The common sense such as the known specific structure and characteristics in the scheme is not described in detail here.
