Description

Technical Field

[0001] The present invention particularly relates to a pain relief device. Background Art

[0002] Back pain refers to acute or chronic pain in the back, which can occur alone or with other discomfort symptoms. The causes of back pain are complex and varied, most of which are caused by local pathological factors, which may be related to various acute and chronic injuries secondary to long-term weight bearing on the back, or may be caused by lesions of adjacent tissues and organs.

[0003] For some back pain, massage and application can be performed at the same time as treatment. Massage is to beat and squeeze the back manually or with a special massager. Application, also known as external application, is a method of grinding the drug into fine powder and mixing it with different media into solid or semi-solid preparations, which are applied to certain acupuncture points or affected areas to treat diseases.

[0004] Then, when treating back pain, most of the existing methods are to perform massage and application separately, that is, either through massage or through application. This not only prolongs the treatment period, but also reduces the chance of coordinated operation of the two methods, thereby reducing the treatment effect.

[0005] In addition, the traditional patch device in clinical practice has a simple structure and mainly uses viscosity to complete the application effect on the patient. It is easy to operate, but in actual use, for some pain, due to the long treatment cycle, the patch needs to be replaced multiple times to relieve the pain. In addition, since the traditional patch device cannot be used multiple times in a cycle, it cannot maximize the therapeutic effect of the drug, which in turn causes a certain amount of waste. Moreover, the application effect is achieved by using viscosity, and when the drug is removed, it will also tear the patient's skin, increasing the patient's pain. Summary of the invention

[0006] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a pain relief device that can simultaneously perform massage and application to relieve the patient's pain, thereby reducing the treatment cycle and improving the treatment effect.

DETAILED DESCRIPTION

[0033] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0034] See also Figures 1 to 5 The present invention provides a pain relief device, including a support plate 100, a massage rod 200, a massage head 300 and a lifting mechanism 400.

[0035] Specifically, a first installation cavity 120 is provided in the support plate 100. A plurality of sockets 110 connected to the first installation cavity 120 are provided in a rectangular row on the top surface of the support plate 100. A massage rod 200 that can slide up and down is inserted into each socket 110. The top end of the massage rod 200 extends out of the socket 110, and the bottom end of the massage rod 200 extends into the first installation cavity 120. The massage head 300 is arranged on the top of the massage rod 200, and a storage bin 310 is provided on the top surface of the massage head 300, and the storage bin 310 is used to store ointment. The lifting mechanism 400 is arranged in the first installation cavity 120 and is connected to all the massage rods 200, and is used to drive some of the massage rods 200 and the remaining massage rods 200 to alternately rise or fall to massage the back.

[0036] When in use, first fill the storage bin 310 with the required ointment, then lay the support plate 100 on the bed surface, then the patient lies on his back on the support plate 100, presses the back where the massage head 300 is needed, and then starts the lifting mechanism 400, which drives some massage rods 200 and the remaining massage rods 200 to alternately rise or fall. In the process of the massage head 300 alternating up and down or falling, it supports the back and massages at the same time. At the same time, when the massage head 300 is pressed against the back, the surface of the ointment inside the storage bin 310 contacts the painful part, and the medicinal ingredients in the ointment treat the painful part.

[0037] The above-mentioned pain relief device can play a role of massage and dressing at the same time. Since the massage and dressing are performed at the same time, the pain treatment time can be greatly shortened. In addition, since the dressing does not need to be attached to the skin, it can avoid the plaster-like dressing from tearing the skin when it is removed. In addition, since the dressing is in intermittent contact with the skin, it can ensure air circulation on the skin where the massage is applied, preventing the occurrence of bedsores.

[0038] Specifically, the lifting mechanism 400 includes a lifting block 410, a first elastic member 410 and a pushing assembly 430. The bottom surface of the first mounting cavity 120 is provided with a slide groove extending along the length direction of the support plate 100, and the slide groove corresponds to the jack 110 one by one. The lifting block 410 is slidably arranged in the slide groove, and the first elastic member 410 is arranged in the slide groove and is consistent with the sliding direction of the lifting block 410. The top surface of the lifting block 410 is a wedge-shaped surface that gradually tilts downward. The end of the massage rod 200 can be slidably placed on the top of the wedge-shaped surface. The pushing assembly 430 can push part of the lifting block 410 and the remaining part of the lifting block 410 to slide alternately in the slide groove. During the reciprocating sliding process of the lifting block 410, the end of the massage rod 200 slides along the wedge-shaped surface to rise or fall.

[0039] When in use, in the initial state, all massage rods 200 are placed on the top of the lifting block 410. When the push assembly 430 is started, the lifting block 410 pushed by the push assembly 430 slides, and the end of the massage rod 200 in contact slides along the wedge surface under the action of gravity and the back, and the massage head 300 moves down. When the push assembly 430 drops the lifting block 410 to push the remaining lifting blocks 410, under the action of the first elastic member 410, the position of the previous part of the lifting block 410 is restored, and the massage rod 200 above this part is pushed up for massage and application, and the massage rod 200 previously located at the highest point position descends to complete this massage stroke, and then the push assembly 430 continues to push the two groups of lifting blocks 410 alternately to move until the treatment is completed.

[0040] In this embodiment, the wedge-shaped surfaces of two adjacent rows of lifting blocks 410 are arranged opposite to each other, and each two adjacent massage rods 200 in the length direction of the massage base plate form a group. The pushing assembly 430 includes a rotational power source 431, a mounting rod 432, and an eccentric wheel 433. A rotatable mounting rod 432 is arranged between each group of lifting blocks 410 extending along the length direction of the support plate 100. A plurality of eccentric wheels 433 are arranged at intervals on the mounting rod 432, and the eccentric wheels 433 correspond to the lifting blocks 410 one by one. When the mounting rod 432 rotates, the eccentric wheel 433 can alternately contact the lifting blocks 410 on the left and right sides and push them to move. The rotational power source 431 is connected to all the mounting rods 432, and is used to simultaneously drive all the mounting rods 432 to rotate forward or reverse.

[0041] When the pushing assembly 430 pushes the lifting block 410 to repeatedly move back and forth along the length direction of the support plate 100 , the two adjacent groups of pushing blocks can be repeatedly pushed to slide alternately, thereby achieving the purpose of alternately rising adjacent massage rods 200 .

[0042] In specific implementation, it is only necessary to drive all the mounting rods 432 to rotate through the rotating power source 431, and the eccentric wheel 433 can alternately drive the push block to move while swinging left and right. It should be noted that in specific implementation, the rotating power source 431 can be any structure in the prior art that can drive all the mounting rods 432 to rotate. For example, a chain sprocket mechanism sets a sprocket at the end of each mounting rod 432, and all the sprockets are connected by a chain. One of the sprockets is connected to a rotating motor, and then all the mounting rods 432 are driven to rotate.

[0043] In this embodiment, the massage rod 200 includes a support rod 210, a sleeve rod 220, a second elastic support member 230 and a fixing structure 240. The support rod 210 and the sleeve rod 220 can be slidably sleeved. The second elastic support member 230 is arranged in the sleeve rod 220 and supported between the top of the support rod 210 and the inner top surface of the sleeve rod 220. The support rod 210 is supported on the lifting block 410, and the massage head 300 is arranged on the top of the sleeve rod 220. The fixing structure 240 is arranged between the sleeve rod 220 and the support rod 210, and can fix the end of the support rod 210 to the sleeve rod 220.

[0044] When in use, the fixing structure 240 first loosens the fixed connection between the support rod 210 and the sleeve rod 220, so that the sleeve rod 220 is in a free state. When the back is pressed against the massage head 300, the sleeve rod 220 is pressed down, so that all the massage heads 300 can automatically adapt to the shape of the back and automatically adjust the height of the massage rod 200. Subsequently, the sleeve rod 220 is fixedly connected to the insertion rod through the fixing structure 240, so that the height of the massage rod 200 is fixed.

[0045] With this arrangement, it can automatically adapt to the shape of the back, thereby effectively massaging and applying the back, avoiding the occurrence of ineffective massage and applying due to an uneven back.

[0046] In this embodiment, the fixed structure 240 includes an airbag 241, a branch air pipe 242, a main air pipe and an inflation device. An airbag 241 is fixedly mounted on each strut 210. The main air pipe is arranged on the air outlet of the inflation device. A pressure relief valve is arranged on the main air pipe. All the airbags 241 are connected to the main air pipe 242 through the branch air pipe 242.

[0047] When the sleeve rod 220 needs to be raised, the gas in the airbag 241 is first released. When the position of the sleeve rod 220 needs to be fixed, it is only necessary to inflate all the airbags 241 through the inflation device so that the airbags 241 expand and press against the inner wall of the insertion hole 110, so that the position of the sleeve rod 220 can be fixed.

[0048] As a preferred embodiment, the device further includes a stirring mechanism 500, which is disposed in the storage bin 310 and is used to stir the ointment in the storage bin 310. Thus, the ointment applied has a chance to contact the human body, thus avoiding the waste of medicine.

[0049] Specifically, the stirring mechanism 500 includes a stirring rod 510, a stirring rod 520 and a second rotation driving device 530. The stirring rod 510 is coaxially arranged inside the sleeve rod 220, and the end of the stirring rod 520 extends into the storage bin, and a plurality of stirring rods 520 are arranged at intervals in the circumferential direction at the end of the stirring rod 520 located in the storage bin. The second rotation driving device 530 is arranged inside the sleeve rod 220 and connected to the stirring rod 520, and is used to drive the stirring rod 510 to rotate counterclockwise or anticlockwise during the process of stirring and driving the stirring rod 510 to move up and down on the sleeve rod 220.

[0050] During use, when the second rotary drive device 530 is started and drives the stirring rod 520 to rotate forward or reversely, the medicine in the storage bin 310 can be stirred.

[0051] Specifically, the second rotation driving device 530 includes a rack 531, a driving shaft 532, a driving gear 533, a first bevel gear 534, a transmission bevel gear assembly 535 and a second bevel gear 536. The rack 531 is vertically installed in the jack 110, and the driving shaft 532 is rotatably arranged in the jack 110 and is perpendicular to the main axis of the jack 110. The driving gear 533 and the first bevel gear 534 are both sleeved and fixed on the driving shaft 532. The side wall of the sleeve rod 220 is provided with a side hole connected to its inner cavity. The driving gear 533 partially penetrates from the side hole and meshes with the rack 531. The second bevel gear 536 is sleeved and fixed on the end of the stirring rod 510, and the transmission bevel gear assembly 535 is connected between the first bevel gear 534 and the second bevel gear 536. Through the transmission bevel gear assembly 535, when the first bevel gear 534 rotates, the second bevel gear 536 can be driven to rotate.

[0052] During use, when the lifting block 410 lifts the massage rod 200 to move up and down, since the rack 531 is fixed, the driving gear 533 can be driven to rotate, and the stirring rod 520 can be driven to rotate through the transmission of the first bevel gear 534, the transmission bevel gear assembly 535 and the second bevel gear 536.

[0053] In this way, stirring and applying can be performed simultaneously, avoiding unnecessary operation steps. In addition, in this way, no extra energy is needed to drive the stirring rod 520 to rotate, further saving energy consumption.

[0054] In addition, in a specific implementation, the device further includes a breathable and water-permeable membrane 600, which can be detachably covered on the storage bin 310, and the top of all storage bins 310 is closed, which can increase the comfort of the patient and prevent the plaster from falling. In a specific implementation, the breathable and water-permeable membrane 600 can be bonded and fixed to the surface of the massage head, and the leak-proof effect is better.

[0055] How to use the above pain relief device:

[0056] When in use, first load the required ointment into the storage bin 310, then lay the support plate 100 on the bed surface, then cover the massage head 300 with the breathable and water-permeable membrane 600, and after the gas in the airbag 241 is released, the patient lies on his back on the device, and then inflates the airbag 241 to fix the length of the massage rod 200, and then starts the rotary power source 431 to drive the rotary power source 431 to rotate the left and right rotary rods, which can drive the massage head 300 to alternately perform massage and application. During the massage process, the stirring rod 510 stirs the ointment differently.

[0057] The above-mentioned pain relief device can play a role of massage and dressing at the same time. Since the massage and dressing are performed at the same time, the pain treatment time can be greatly shortened. In addition, since the dressing does not need to be attached to the skin, the plaster-type dressing can avoid tearing the skin when it is removed. In addition, since the dressing is in intermittent contact with the skin, it can ensure air circulation of the skin at the massage dressing site to prevent the occurrence of bedsores. In addition, the rectification device can make the best use of the medicinal properties of the ointment to prevent the waste of the ointment.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
