Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of skin traction devices, and in particular relates to a skin traction device. Background Art
[0002] Skin traction is an important and effective treatment measure that is widely used in orthopedic clinical work. It is mainly suitable for the auxiliary fixation treatment of stable intertrochanteric fractures in the elderly or before and after surgery. Its traction force reaches the bones or joints indirectly through the skin, fascia and muscles.
[0003] Existing skin traction devices generally include a covering mechanism and a traction mechanism. The covering mechanism is used to cover the patient's limbs, and the traction force is transmitted to the covering mechanism through the traction mechanism to maintain the reduction and stability of the fracture. Existing covering mechanisms are mostly made of foam materials, which are easy to cause allergies in patients, and need to be used with heat exchange trousers during use. The foam material is not breathable, and the covered part of the patient's limbs is prone to sweating, which is easy to cause discomfort in the covered part of the patient's limbs. In addition, the traction time is generally based on the doctor's advice, and the single time is 30 to 180 minutes. The longer the traction time, the more likely the airtight covering mechanism will cause discomfort to the patient. If the traction time is too long, the patient's limbs are forced to position, which is easy to compress the common peroneal nerve and cause foot drop. Long-term foot drop may cause changes in the patient's foot structure, thereby causing other complications caused by skin traction, which is not conducive to the patient's recovery.

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0033] like Figure 1 to Figure 4 As shown, a skin traction device in one embodiment of the present invention includes a covering mechanism, which covers the patient's limb and applies a certain traction force to the covering mechanism. This traction force can be transmitted from the covering mechanism to the skin of the affected limb, and then to the fascia and muscles in turn, and then indirectly reaches the bones or joints to maintain the reduction and stability of the fracture.
[0034] like Figure 1 to Figure 4As shown, the covering mechanism includes a first leg cover 1 and a second leg cover 2, which are connected by a connecting belt 4, and a traction belt 5 is installed between the first leg cover 1 and the second leg cover 2, and the traction belt 5 is used to bear the traction force and transmit the traction force to the first leg cover 1 and the second leg cover 2, and the traction force is then transmitted to the affected limb by the first leg cover 1 and the second leg cover 2. The first leg cover 1 is composed of a first leg cover covering portion 101 and a second leg cover covering portion 102, and the second leg cover 2 is composed of a third leg cover covering portion 201 and a fourth leg cover covering portion 202. The first leg cover covering portion 101 and the third leg cover covering portion 201, the second leg cover covering portion 102 and the fourth leg cover covering portion 202 are exactly the same, and the only difference is their length. The length of the first leg cover 1 is less than that of the second leg cover 2. The first leg cover 1 plays a main traction role, while the second leg cover 2 plays an auxiliary traction and auxiliary fixation role.
[0035] Specifically, the first leg cuff covering portion 101, the second leg cuff covering portion 102, the third leg cuff covering portion 201 and the fourth leg cuff covering portion 202 are all fixedly connected to the connecting belt 4, and the first leg cuff covering portion 101, the second leg cuff covering portion 102, the third leg cuff covering portion 201 and the fourth leg cuff covering portion 202 can be bent and wrap the patient's affected limb respectively. The first leg cuff covering portion 101 and the third leg cuff covering portion 201 are respectively fixedly connected with the first connecting portion 6, and the second leg cuff covering portion 102 and the fourth leg cuff covering portion 202 are respectively fixedly connected with the second connecting portion 7 matching the first connecting portion 6. The first connecting portion 6 and the second connecting portion 7 cooperate to fasten the first leg cuff covering portion 101 and the second leg cuff covering portion 102, the third leg cuff covering portion 201 and the fourth leg cuff covering portion 202 wrapped on the affected limb, so that the first leg cuff 1 and the second leg cuff 2 are not easy to fall off the affected limb. During the traction process, the first leg cuff 1 and the second leg cuff 2 can fit firmly with the affected limb to facilitate the transmission of traction force.
[0036] The first connection part 6 and the second connection part 7 can be a Velcro fleece surface and a sticky surface, and the Velcro fleece surface and the sticky surface can cooperate to fasten the first leg cover 1 and the second leg cover 2 wrapped on the affected limb. Of course, the first connection part 6 and the second connection part 7 can also be other fastening structures, such as plastic buckles, straps, etc.
[0037] like Figure 1 to Figure 4 As shown, the connecting belt 4 has a certain hardness. In actual use, the connecting belt 4 is placed on the bed surface. The connecting belt 4 can fit the bed surface to ensure that the first leg cover 1 and the second leg cover 2 are evenly wrapped on the affected limb as much as possible, and the magnitude of the transmitted traction force is ensured to be the same as much as possible, so that the traction force is transmitted to the affected limb as symmetrically as possible, which is more conducive to the auxiliary fixation treatment of the affected limb.
[0038] like Figure 1 to Figure 4As shown, the end of the connecting belt 4 away from the second leg cover 2 is slidably connected to the foot support 3, which can support the patient's foot, prevent the patient's foot from dropping during the skin traction process, and prevent pressure damage caused by the traction belt compressing the foot skin. The foot support 3 can be made of elastic material, and the initial size of the foot support 3 is suitable for small feet, but large feet can also be inserted into the foot support 3 and can play a role in supporting the foot. The connecting belt 4 can adapt to feet of different sizes, and the larger the foot, the stronger the wrapping feeling.
[0039] like Figure 1 to Figure 4 As shown, a positioning groove 401 is provided at one end of the connecting belt 4 away from the second leg cover 2, and a positioning block 301 matching the positioning groove 401 is fixedly connected to the bottom of the foot support 3, and the positioning block 301 can be stuck in the positioning groove 401 to achieve the initial fixation of the foot support 3. The connecting belt 4 is fixedly connected with a third connecting part 9 on both sides of the positioning groove 401, and the bottom of the foot support 3 is fixedly connected with a fourth connecting part 10 matching the third connecting part 9. The third connecting part 9 and the fourth connecting part 10 are connected to each other, and the foot support 3 can be tightly fixed on the connecting belt 4. During the skin traction process, even if the patient's foot pushes the foot support 3 hard, the position of the foot support 3 is not easy to shake.
[0040] The third connection part 9 and the fourth connection part 10 may specifically be a Velcro fleece surface and a sticky surface.
[0041] like Figure 1 to Figure 4 As shown, one end of the traction belt 5 away from the second leg cuff 2 is fixedly connected to a connecting rod 501, a connecting ring is fixed in the middle of the connecting rod 501, and a first traction rope 8 is installed on the connecting ring. By applying traction force to the first traction rope 8, the first traction rope 8 transmits the traction force to the connecting rod 501, the traction belt 5, the first leg cuff 1 and the second leg cuff 2 in turn. The connecting ring is located in the middle of the connecting rod 501, which can further improve the uniformity of the traction force transmitted to the affected limb, which is beneficial to assisting the treatment of the affected limb.
[0042] like Figure 1 to Figure 4 As shown, the inner wall of the foot support 3 is fixedly connected with the first airbag 11, the second airbag 12 and the third airbag 13, the second airbag 12 can contact the sole of the patient's foot, the third airbag 13 can contact the heel of the patient, and the first airbag 11 can contact the side of the patient's foot. In addition, the first airbag 11, the second airbag 12 and the third airbag 13 can be inflated to change the size of the first airbag 11, the second airbag 12 and the third airbag 13, so that the first airbag 11 can wrap a smaller foot, and at the same time can improve the patient's comfort and prevent pressure injuries of the heel caused by limb braking.
[0043] Specifically, by inflating the first airbag 11, the second airbag 12 and the third airbag 13, the posture of the patient's foot can also be changed. By changing the amount of air in the first airbag 11, the second airbag 12 and the third airbag 13, autonomous ankle pump movement can be simulated to reduce the braking of the affected limb caused by the skin traction device, which leads to slow blood flow and easily causes deep vein thrombosis in the lower limbs.
[0044] Preferably, a plurality of convex balls (not shown) may be provided on the surfaces of the first airbag 11, the second airbag 12 and the third airbag 13. During the process of inflation and deflation, the convex balls may contact the foot to massage the foot.
[0045] Preferably, the end of the foot support 3 that contacts the sole of the foot is rotatable forward and backward (not shown in the figure), and is generally driven by a motor. When the patient's foot contacts the foot support 3, by changing the angle of the end of the foot support 3 that contacts the sole of the foot, the dorsiflexion of the foot can be as high as 45° and the plantar flexion can be as high as 30°, thereby simulating the movement of the patient's foot, promoting passive movement of the affected limb, and preventing the occurrence of deep vein thrombosis in the lower limbs.
[0046] During daily care, nurses need to observe the swelling, subcutaneous congestion, and blood circulation of the affected limbs every shift, and they need to open the covering mechanism to measure the leg circumference every shift. During the measurement process, the patient's pain and discomfort will be aggravated, and it is also inconvenient for nurses to observe and care for the patient. To solve the above problems, a soft scale (not shown in the figure) can be installed on the covering mechanism to facilitate the measurement of leg circumference without opening the covering mechanism and moving the affected limb for measurement, which is convenient for nurses to measure and reduces the pain and discomfort of the patient caused by moving.
[0047] In this embodiment, the working principle of the wrapping mechanism is as follows: first, place the affected limb in the first leg cuff 1 and the second leg cuff 2, confirm the position to be wrapped, wrap the first leg cuff wrapping part 101, the second leg cuff wrapping part 102, the third leg cuff wrapping part 201 and the fourth leg cuff wrapping part 202 around the affected limb, and tighten them by the cooperation of the first connecting part 6 and the second connecting part 7. At this time, the position of the patient's foot does not change, and the foot support 3 can be installed on the connecting belt 4. The installation position of the foot support 3 is determined by the preliminary cooperation of the positioning groove 401 and the positioning block 301, and then further fixed by the third connecting part 9 and the fourth connecting part 10. And by filling and releasing air into the first airbag 11, the second airbag 12 and the third airbag 13, the foot support 3 can adapt to the patient's foot and support the patient's foot. Then the first traction rope 8 is fixed to the connecting ring, and traction force is applied to the first traction rope 8. The traction force is transmitted from the first traction rope 8 to the connecting rod 501, the traction belt 5, the first leg cuff 1 and the second leg cuff 2 in sequence, and then transmitted to the affected limb by the first leg cuff 1 and the second leg cuff 2 to achieve skin traction of the patient's affected limb.
[0048] In this embodiment, the contact layer 25 is made of air fiber material. The air fiber is formed by interweaving a special ultra-fine fiber-shaped resin new material. The raw material is ultra-fine polyethylene fiber. This material is the same as the material of the food container, which is safe and harmless to the body and can be used with confidence. It can directly contact the skin of the affected limb. It has the advantages of not easy to be allergic, good air permeability, and not easy to sweat. If there is a stain, it can be directly washed with water, and it is easy to dry and can be used repeatedly.
[0049] In another embodiment, if Figure 5-6 As shown, the leather traction device includes a traction mechanism, which is used to apply traction to the covering mechanism. The traction mechanism includes a mounting seat 14, and the lower end of the mounting seat 14 is fixedly connected to a plurality of universal wheels 15, which facilitate the movement of the traction mechanism. The upper end of the mounting seat 14 is fixedly connected to a bracket 21, and a positioning wheel 22 is installed on the bracket 21. A second traction rope 24 is slidably connected in the positioning wheel 22. The end of the second traction rope 24 close to the mounting seat 14 is fixedly connected to a traction block 23, and the other end is fixedly connected to the first traction rope 8. The traction block 23 is not in contact with the bracket 21 and the mounting seat 14, and is suspended in the air. The gravity generated by it is transmitted to the first traction rope 8 through the second traction rope 24, and the traction force generated by it is equal to the gravity generated by it. Therefore, when the required traction force of the covering mechanism needs to be changed, the mass of the traction block 23 itself can be changed or more weight-increasing mechanisms can be added to the traction block 23, so that the traction force generated by the traction mechanism can meet the requirements of the covering mechanism.
[0050] like Figure 5 As shown, a knot 2401 is fixedly connected to the second traction rope 24 , and the knot 2401 can ensure that the second traction rope 24 will not be separated from the bracket 21 .
[0051] In order to realize the change of traction force more intelligently, a traction body 16 is installed between the bracket 21 and the mounting seat 14, and the bracket 21 is fixedly connected to the upper end of the traction body 16. Several groups of electromagnetic blocks 19 are fixedly connected inside the traction body 16, and the traction block 23 can be adsorbed by the electromagnetic block 19. The traction block 23 has an initial weight, which can be specifically 1kg. According to the doctor's advice, when performing skin traction, if a traction force of 2kg is required, the electromagnetic block 19 is started, so that the electromagnetic block 19 adsorbs the traction block 23, and the force of the electromagnetic block 19 adsorbing the traction block 23 is equal to 1kg. At this point, the intelligent change of traction force can be completed, without the need to manually increase or decrease the weight block to achieve the change of traction force, and the traction force generated by the electromagnetic block 19 and the traction block 23 is more accurate and faster.
[0052] When the skin traction device is performing skin traction, it needs to last for a certain period of time. If the time is up and the traction force is not removed, the skin traction time will be too long. Too long or too short a skin traction time is not conducive to the recovery of the affected limb. Through the cooperation of the electromagnetic block 19 and the traction block 23, timed traction can be achieved, that is, after the skin traction is completed, the electromagnetic block 19 changes its magnetic poles, so that the traction block 23 and the electromagnetic block 19 repel each other, and the repulsive force generated by the electromagnetic block 19 is equal to or greater than the mass of the traction block 23 itself, thereby achieving the effect of removing the traction force, ensuring the traction time of the affected limb, and not affecting the recovery of the affected limb due to too long or too short a skin traction time.
[0053] like Figure 5 As shown, a controller 20 is installed in the traction body 16. During the use of the electromagnetic block 19, it is usually controlled by the controller 20. The controller 20 can be connected to the mobile device end and the PC end through Bluetooth, WiFi, etc. to realize the remote control of the traction mechanism. And during the use of the electromagnetic block 19, the electromagnetic block 19 can also increase or decrease the traction force during the skin traction process, that is, the adsorption force of the electromagnetic block 19 on the traction block 23 can be increased or decreased, thereby simulating muscle massage, which is more conducive to relaxing the muscles around the fracture and facilitating the treatment of the patient. During the use of the electromagnetic block 19, the traction force can also be reduced according to the patient's own situation. The traction force provided to the affected limb by the covering mechanism is more accurate, which is more conducive to the recovery of the affected limb or muscle relaxation.
[0054] In general, the traction force needs to be kept parallel to the patient's affected limb, which is more conducive to the recovery of the affected limb. In order to make the traction mechanism adapt to beds of different heights, such as Figure 5-6 As shown, a telescopic rod 18 is installed between the mounting seat 14 and the traction body 16. The telescopic rod 18 can change the height of the traction body 16, thereby changing the height of the positioning wheel 22, so that the traction force can be parallel to the first traction rope 8, and the traction force transmitted to the affected limb is parallel to the bed surface. The upper end of the mounting seat 14 is also fixedly connected to a plurality of positioning rods 17, and the positioning rods 17 are slidably connected to the traction body 16, which can keep the traction body 16 stable and not prone to shaking during the process of the telescopic rod 18 lifting the traction body 16. At the same time, it can also provide auxiliary support, which is conducive to increasing the service life of the telescopic rod 18.
[0055] like Figure 6 As shown, the second traction rope 24 and the first traction rope 8 are generally connected by a clamping method. After the leather traction is completed, the second traction rope 24 and the first traction rope 8 are disconnected. The traction mechanism can exert traction force on other covering mechanisms, thereby improving the utilization rate of the traction mechanism.
[0056] In this embodiment, the working principle of the traction mechanism is as follows: first determine the height of the covering mechanism, lift the first connection part 6 through the first traction rope 8, and the height of the positioning wheel 22 changes with the first connection part 6 until the positioning wheel 22 is on the same horizontal line as the first traction rope 8. Then connect the second traction rope 24 to the first traction rope 8 to provide preliminary traction to the affected limb. According to the doctor's order, the force generated by the electromagnetic block 19 adsorbing the traction block 23 + the gravity generated by the traction block 23 itself = the traction force of the doctor's order. Under the doctor's order traction force, the traction force can be increased or decreased according to the condition of the affected limb by changing the suction force of the electromagnetic block 19 adsorbing the traction block 23. After the traction time is up, the magnetic poles of the electromagnetic block 19 change, the electromagnetic block 19 and the traction block 23 repel each other, and the repulsive force generated by the electromagnetic block 19 is equal to or greater than the gravity of the traction block 23 itself. The repulsive force generated by the electromagnetic block 19 lifts the traction block 23. At this time, the traction force of the covering mechanism is small, and the traction force can be canceled at a timely manner even when medical staff are not present, which can reduce the energy consumed by medical staff in caring for patients.
[0057] In another embodiment, if Figure 7-8 As shown, the first leg cover covering part 101, the second leg cover covering part 102, the third leg cover covering part 201 and the fourth leg cover covering part 202 all include a contact layer 25, the contact layer 25 contacts the affected limb, and a constant temperature layer 26 is provided at one end of the contact layer 25 away from the affected limb, and the constant temperature layer 26 can play a role in cooling down. Even if the first leg cover 1 and the second leg cover 2 are made of highly breathable air fiber material, the temperature of the affected limb wrapped is likely to rise, and the affected limb will sweat. By providing the first connecting part 6, the sweating of the affected limb wrapped can be greatly reduced, and the comfort of use of the covering mechanism can be improved.
[0058] like Figure 7-8 As shown, an airflow cavity 27 is provided at one end of the first connection portion 6 away from the affected limb. The airflow cavity 27 is a hollow shell with a certain elasticity. A first air pipe 28 is installed in the contact layer 25. A plurality of evenly distributed first air nozzles 29 are fixedly connected to the first air pipe 28. Through the cooperation of the first air pipe 28 and the first air nozzle 29, gas can be input into the airflow cavity 27. A second air pipe 30 is also installed on the contact layer 25. A plurality of second air nozzles 31 for air outlet are installed on the second air pipe 30. The second air pipe 30 and the second air nozzle 31 cooperate to output the gas in the airflow cavity 27. When the affected limb is wrapped, the cooperation of the first air pipe 28, the first air nozzle 29, the second air pipe 30, the second air nozzle 31 and the airflow cavity 27 can form a circulating heat dissipation duct at the wrapped part of the affected limb, realize the cooling operation at the wrapped part of the affected limb, avoid sweating at the wrapped part, and reduce the discomfort of the affected limb caused by sweating.
[0059] Moreover, the speed of the heat dissipation air duct is controllable, and a temperature sensing component (not shown in the figure) may be provided to measure the temperature of the affected limb according to the temperature sensing component, change the speed of the heat dissipation air duct, or perform heat dissipation intermittently.
[0060] like Figure 7-8 As shown, a plurality of anti-skid protrusions 35 are provided on a surface of the contact layer 25 that contacts the affected limb. The anti-skid protrusions 35 can increase the distance between the contact layer 25 and the affected limb, and can also increase the friction between the contact layer 25 and the affected limb, so that the covering mechanism is not easy to fall off the affected limb. The heat dissipation airway can also pass through the gap formed by the anti-skid protrusions 35 and the affected limb. With the presence of the anti-skid protrusions 35, the first air nozzle 29 and the second air nozzle 31 are not easily blocked by the skin of the affected limb, resulting in a situation where air cannot be inhaled or exhaled.
[0061] It is worth noting that when the first air nozzle 29 and the second air nozzle 31 are completely blocked by the affected limb, the first air nozzle 29 and the second air nozzle 31 will not work, thereby largely avoiding discomfort to the skin of the affected limb caused by the first air nozzle 29 and the second air nozzle 31 being blocked.
[0062] like Figure 7-8 As shown, a plurality of separate mounting platforms 32 are provided on the airflow chamber 27, and an elastic part 33 is installed between adjacent mounting platforms 32. The elastic part 33 is made of elastic rubber material, and a massage ball 34 is fixedly connected to the upper end of the mounting platform 32. When the first air nozzle 29 takes in air and the second air nozzle 31 does not exhaust air, a high-pressure environment will be formed inside the airflow chamber 27. According to the size of the air intake, the elastic part 33 will deform to a certain extent. When the air intake in the airflow chamber 27 is sufficient, the elastic part 33 will deform, and the mounting platform 32 will move toward one end of the affected limb, causing the massage ball 34 to press the affected limb, massage the affected limb, and relieve the affected limb. After the air intake in the airflow chamber 27 reaches the threshold, the second air nozzle 31 will exhaust air. In this way, the affected limb can be massaged and the affected limb can be relieved after skin traction.
[0063] Among them, a first air nozzle 29 and a second air nozzle 31 do not act on the affected limb, and the air intake direction of the first air nozzle 29 is parallel to the air outlet direction of the second air nozzle 31, that is, the air intake of the first air nozzle 29 and the air outlet of the second air nozzle 31 do not affect the affected limb. When the affected limb does not need to dissipate heat but needs massage, the air intake and air outlet in the airflow cavity 27 can be realized through the first air nozzle 29 and the second air nozzle 31 parallel to the affected limb, driving the massage ball 34 to move, achieving the effect of massaging the affected limb.
[0064] In another embodiment, if Figure 9-10As shown, the foot support 3 is hard, and the foot support 3 is composed of a first foot support 302, a second foot support 303 and a foot support mounting plate 304. The first foot support 302 and the second foot support 303 are slidably connected to the upper end of the foot support mounting plate 304, and the size of the foot support can be freely adjusted according to the feet of different sizes, which is more suitable and increases comfort. The positioning block 301 and the fourth connecting part 10 are fixedly connected to the end of the foot support mounting plate 304 away from the first foot support 302, and are used to connect with the connecting belt 4. The positions of the first foot support 302 and the second foot support 303 can be changed to facilitate adaptation to feet of different sizes and to facilitate use by patients who do not want too strong wrapping.
[0065] Specifically, Figure 9-10 As shown, a slide groove 3041 is provided on the foot support mounting plate 304, and a slider 305 matching the slide groove 3041 is fixedly connected to the lower ends of the first foot support 302 and the second foot support 303. The slider 305 slides in the slide groove 3041, and the slider 305 and the side wall of the slide groove 3041 are interference fit. That is, when the first foot support 302 and the second foot support 303 slide to a suitable position, the current state can be maintained.
[0066] The present invention can achieve skin traction of the affected limb through the covering mechanism and the traction mechanism, and in the process of skin traction, can provide accurate traction force according to the needs of the affected limb, which is more conducive to the recovery of the affected limb and muscle relaxation, and the traction mechanism has a timing function, even in the absence of medical staff, the traction mechanism can also remove the traction force after the traction time is reached. The traction mechanism can provide traction force for covering mechanisms at different heights, and the traction force is parallel to the covering mechanism, which is more conducive to the recovery of the affected limb and muscle relaxation.
[0067] The present invention sets a foot support 3 in the covering mechanism, which can support the patient's foot and simulate autonomous ankle pump movement to prevent the occurrence of deep vein thrombosis in the lower limbs and avoid other complications caused by the patient during skin traction as much as possible. The position of the foot support 3 can be changed according to the position of the patient's foot, and its size can also be changed according to the patient's foot, which is more adaptable and more practical.
[0068] The present invention sets a massage ball 34 in the covering mechanism. Through the cooperation of the first air tube 28, the first air nozzle 29, the second air tube 30, the second air nozzle 31 and the air flow chamber 27, the massage ball 34 is controlled to press the affected limb to achieve massage of the affected limb, which is beneficial to the recovery of the affected limb, relaxation of muscles, etc.; and through the cooperation of the first air tube 28, the first air nozzle 29, the second air tube 30, the second air nozzle 31 and the air flow chamber 27, it is also possible to facilitate the heat dissipation of the affected limb, reduce sweating of the affected limb, and help improve the comfort of using the covering mechanism.
