Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine rehabilitation therapy technology, specifically to a fumigation therapy device for treating brain diseases. Background Technology

[0002] Brain diseases are a group of serious neurological disorders that threaten human health, encompassing a variety of conditions such as stroke, Parkinson's disease, Alzheimer's disease, post-traumatic brain injury sequelae, and epilepsy. These diseases often lead to symptoms such as cognitive impairment, motor dysfunction, and difficulty in language expression, severely affecting patients' quality of life and gradually causing them to lose their ability to live independently. In Traditional Chinese Medicine, current techniques typically employ fumigation therapy to treat brain diseases.

[0003] According to a search, Chinese patent document CN215022091U discloses a fumigation therapy rehabilitation bed for neurological nursing. By pressing down on the handle, two sets of connecting rods move a concave baffle downwards. When it reaches the appropriate position, rotating the threaded rod causes the moving block to engage with the convex ball, preventing the connecting rods from moving further downwards. At this point, the concave baffle covers the patient's neck. The concave baffle allows the patient to receive steam therapy while the opening of the groove is blocked, thus enabling the patient to receive the treatment more completely.

[0004] However, the aforementioned fumigation equipment has the following drawbacks in actual use: It lacks a targeted fumigation structure, causing the medicinal steam generated during use to cover the entire area of ​​the patient's head indiscriminately, rather than focusing on the affected area. This leads to ineffective consumption of medicinal steam in non-lesion areas, reducing drug utilization efficiency; furthermore, for lesion areas, the inability to concentrate the medicinal steam makes it difficult to achieve the ideal therapeutic concentration, thus affecting the treatment effect. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 7The present invention provides a fumigation therapy device for treating brain diseases, comprising a positioning fumigation therapy mechanism 1, which includes a headrest 101. Connecting frames 102 are bolted to both sides of the headrest 101. Expansion rings 103 are snapped into the interior of both sides of the connecting frames 102. A connecting pipe 104 is inserted into the interior of the expansion rings 103. A tee connector 105 is threaded to one end of the connecting pipe 104, and a pipe joint 106 is fixedly connected to the other end of the connecting pipe 104. The outer wall of the pipe joint 106... A triangular block 107 is fixedly connected, and a cam 108 is rotatably connected to the inner side of the triangular block 107. A lever 109 is fixedly connected to the outer wall of the cam 108. An insert tube 110 is snapped into the inside of the pipe connector 106. An arc-shaped gas supply pipe 111 is fixedly connected to one end of the insert tube 110. A ball valve 112 is threadedly connected to the outer wall of the arc-shaped gas supply pipe 111. A bellows 113 is threadedly connected to one end of the ball valve 112. An air cover 114 is fixedly connected to one end of the bellows 113. For details on the structure of pillbox assembly 2, please refer to [link / reference]. Figure 8 It includes a box body 201, a dispersion plate 202 fixedly connected to the inner wall of the box body 201, a cone 203 threadedly connected to the bottom of the box body 201, a guide plate 204 fixedly connected to the inner wall of the cone 203, a box cover 205 snapped onto the top of the box body 201, and an air outlet 206 fixedly connected to the outer wall of the box cover 205.

[0022] Furthermore, a T-shaped clip is fixedly connected to the outer wall of the connecting frame 102, a support plate 3 is clipped onto the outer surface of the T-shaped clip, a support plate 4 is fixedly connected to the bottom of the support plate 3, and a triangular reinforcing rib is fixedly connected between the support plate 3 and the support plate 4.

[0023] Furthermore, a sealing cover 5 is snapped onto the top of the tray 4, and a U-shaped opening is provided on one side of the sealing cover 5. The sealing cover 5 is made of transparent plastic. Two sets of telescopic rods 6 are connected to the bottom of the tray 4 by screws, and the bottom end of the telescopic rods 6 is connected to a base 7 by screws.

[0024] Four sets of universal casters with locking structures are installed on the lower surface of the base 7, making it easy to move the entire fumigation device. This fumigation device needs to be used with a bed. The height of the support plate 4 can be adjusted by setting the telescopic rod 6, which can drive the adjustment and positioning of the fumigation mechanism 1 and the medicine box assembly 2, and thus adjust the height of the headrest 101 so that the height of the headrest 101 matches the height of the bed. The structure of the telescopic rod 6 can be completely adopted from existing technology, and can be a manually adjustable telescopic structure or an electrically adjustable telescopic structure. During the fumigation treatment for brain diseases, the patient can lie on the bed with the back of their head supported by the headrest 101, so that the patient can receive the fumigation treatment while lying down, allowing the patient to relax more.

[0025] Furthermore, the fumigation device body 8 is placed on the top surface of the base 7, and the top of the fumigation device body 8 is snapped into the top of the top cover 9. An exhaust nozzle is fixedly connected to the top of the top cover 9, and a first hose 10 is inserted into the outer surface of the exhaust nozzle. The end of the first hose 10 away from the exhaust nozzle is connected to the cone 203.

[0026] Furthermore, multiple guide plates 204 are fixedly connected to the inner wall of the cone 203 around its axis. The multiple guide plates 204 are spaced at the same distance and are spiral in shape. A connecting ring 207 is fixedly connected to the outer wall of the box 201. The connecting ring 207 is connected to the upper surface of the support plate 4 by screws.

[0027] Furthermore, the top surface of the dispersion plate 202 is provided with multiple air holes around its axial direction, the inner wall of the box body 201 is fixedly connected with a retaining ring 208, and the top of the box body 201 is provided with two slots 209. The bottom edge of the box cover 205 is fixedly connected with two limiting pieces 210, and the inner wall of the box body 201 is provided with two grooves 211 arranged in an array around its axial direction.

[0028] By placing the medicine pack needed for fumigation on the upper surface of the dispersion plate 202, and then covering the top of the box body 201 with the box cover 205, the limiting piece 210 is inserted into the slot 209. At this time, the bottom of the box cover 205 abuts against the retaining ring 208. Then, the box cover 205 is rotated to make the limiting piece 210 rotate, so that the limiting piece 210 can be inserted into the groove 211, thus fixing the box cover 205 to the top of the box body 201. When the fumigation device body 8 starts to work and generates steam, the steam enters the cone 203 through the first hose 10. Since there are multiple spiral guide plates 204 with the same spacing on the inner wall of the cone 203, the steam entering from the first hose 10 can be guided to spiral upward. This can prolong the residence time of the steam in the cone 203, so that the water vapor penetrates the multiple air holes on the dispersion plate 202, and the steam is evenly dispersed and acts on the medicine pack placed on it. In this way, the steam can fully contact the medicine pack to release the medicinal effect.

[0029] Furthermore, the air outlet 206 is fixedly connected to the conical surface of the cover 205, and a second hose 11 is inserted into the end of the air outlet 206 away from the cover 205. A hose connector 12 is inserted into the end of the second hose 11 away from the air outlet 206. The outer wall of the hose connector 12 is threaded and inserted into the side wall of the headrest 101 and fixed by a nut. A third hose 13 is inserted into the end of the hose connector 12 away from the second hose 11. A three-way pipe head 105 is inserted into the end of the third hose 13 away from the hose connector 12. A connecting pipe 104 is threaded to both ends of the three-way pipe head 105.

[0030] The second hose 11 is connected to the hose connector 12 and the air outlet 206. After the steam passes through the medicine pack, it activates the medicine. At this time, the steam containing the medicine enters the third hose 13, and then enters the three-way connector 105. The steam then enters the two connecting pipes 104. Subsequently, the sleeve connector 106 and the insertion tube 110 enter the arc-shaped gas delivery pipe 111. By opening the ball valve 112, the steam can enter the bellows 113 and finally be discharged from the gas hood 114.

[0031] Furthermore, a sealing gasket is provided on the inner wall of the pipe joint 106, and an annular groove is provided on the outer wall of the insertion tube 110. The annular groove fits tightly with the cam 108, and several ball valves 112 are connected to the outer wall of the arc-shaped gas transmission pipe 111 by threads at equal intervals.

[0032] By moving the lever 109, the cam 108 rotates around the axis connected to the triangular block 107. Since the cam 108 engages with the annular groove on the outer wall of the cannula 110, it can deviate from the annular groove of the cannula 110 after rotation. At this point, the cannula 110 is no longer clamped. Rotating the arc-shaped gas delivery tube 111 allows the cannula 110 to rotate within the tube connector 106. The arc-shaped gas delivery tube 111 also allows components such as the air mask 114 to rotate around the axis of the cannula 110. This allows adjustment of the position of multiple air masks 114, making it easier for them to approach the lesion area on the patient's head. Pressing the lever 109 down again resets the cam 108, allowing it to press against the annular groove of the cannula 110 and ensure the cannula 110 is tightly against the tube connector 106. The sealing gasket inside 06 ensures that steam will not leak. Because the corrugated pipe 113 can be bent and shaped, the air hood 114 can be further fitted to the scalp area outside the lesion. Several corrugated pipes 113, ball valves 112 and air hoods 114 are arranged around the arc-shaped air supply pipe 111. In this way, one or more ball valves 112 can be selectively opened to allow steam to enter one or more corrugated pipes 113 from the arc-shaped air supply pipe 111. The corresponding air hood 114 is then fitted to the scalp outside the lesion. The overall structure achieves targeted fumigation therapy to the lesion area on the patient's head. This design not only solves the problem of ineffective consumption caused by the general coverage of drug steam in traditional fumigation equipment, but also allows the lesion area to receive a sufficient concentration of drug steam, significantly improving the fumigation effect.

[0033] Furthermore, the top surface of the headrest 101 is provided with an arc-shaped groove, and the outer surface of the headrest 101 is covered with a memory foam padding layer, and the surface of the memory foam padding layer is provided with ventilation holes.

[0034] The curved groove on the top surface of the headrest 101 conforms to the physiological curve of the back of the patient's head, providing stable support for the head. The memory foam padding layer covering the outer surface has good softness and resilience, and can adaptively shape according to the contour of the patient's head, improving the comfort of head placement and reducing the pressure caused by prolonged fumigation. It is worth noting that during the fumigation of the brain, the sealing cover 5 is fastened to the support plate 4, at which time the part of the patient's head above the bridge of the nose is inside the sealing cover 5. A U-shaped opening is opened on the outer wall of the sealing cover 5 for the part of the head below the bridge of the nose and close to the neck. A towel can be covered at the U-shaped opening of the sealing cover 5, which, together with the sealing cover 5, prevents the steam from dissipating quickly.

[0035] Furthermore, a sealing ring is fitted between the fumigation device body 8 and the top cover 9, and a sealing ring is also fitted between the box cover 205 and the retaining ring 208. The fumigation device body 8 is equipped with an inner liner, and the inner wall of the inner liner is engraved with capacity scale lines.

[0036] Water is injected into the inner liner of the fumigation device body 8, and the capacity scale lines engraved on the inner wall of the inner liner make it easy to control the amount of water injected; the sealing ring between the fumigation device body 8 and the top cover 9, as well as the sealing ring between the box cover 205 and the retaining ring 208, can effectively enhance the sealing of each connection part and prevent steam from leaking from the gaps during transmission.

[0037] In use, firstly, use the universal wheels with locking structure on the lower surface of the base 7 to move the device to a suitable position and lock it. Adjust the height of the telescopic rod 6 to match the height of the headrest 101 with the height of the bed. Then, place the fumigation medicine pack on the upper surface of the dispersion plate 202 of the medicine box assembly 2, align the limiting piece 210 of the box cover 205 with the slot 209 of the box body 201 and insert it. Rotate the box cover 205 to make the limiting piece 210 snap into the groove 211, thus fixing the box cover 205 to the box body 201. Next, connect the exhaust nozzle of the fumigation device body 8 to the cone 203 through the first hose 10, and connect the exhaust nozzle 206 of the box cover 205 to the hose connector 12 on the side wall of the headrest 101 through the second hose 11, ensuring that all pipes are tightly connected. Then, to After filling the inner tank of the fumigation device body 8 with clean water, cover it with the top cover 9, and then start the fumigation device body 8 to generate steam. The patient lies on the bed with the back of their head resting on the head pillow 101. The patient moves the lever 109 to adjust the angle of the intubation tube 110 and the arc-shaped air delivery tube 111 so that the air mask 114 is close to the lesion area on the head. Then, the flexibility of the corrugated tube 113 is used to make the air mask 114 fit the scalp area outside the lesion. Then, the lever 109 is reset to fix the position. Finally, the ball valve 112 corresponding to the lesion area is opened so that the medicated steam is discharged from the air mask 114 through the pipeline and acts on the scalp outside the lesion. At the same time, the sealing cover 5 is put on the support plate 4, and a towel is covered at the U-shaped opening to prevent the steam from dissipating. After the fumigation treatment, the fumigation device body 8 is turned off and the relevant parts are cleaned for the next use.
