Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment and devices, and in particular relates to a device for palliative care. Background Art

[0002] Palliative care refers to the analgesic care process, which is aimed at cancer patients with pain symptoms. There are many methods of palliative care, including drug analgesic treatment methods and non-drug analgesic treatment methods. Specific treatment methods include ear acupoint pressing treatment, moxibustion treatment, acupoint cupping treatment, Chinese medicine hot pack treatment, etc. Among them, the Chinese medicine hot pack is a medicine bag obtained by crushing Chinese medicinal materials and placing them in a gauze bag or a non-woven bag. The Chinese medicine hot pack treatment requires that the Chinese medicine hot pack be heated first, and then the patient is subjected to hot compress to achieve the purpose of allowing the active ingredients of the medicine to penetrate into the patient's body or heat circulation. The specific method of Chinese medicine hot pack treatment is usually to place a towel on the body, and then place the heated Chinese medicine hot pack on the towel. At this time, the towel mainly plays a heat-insulating role to avoid scalding the patient. However, the existing technology does not have adequate insulation measures for the Chinese medicine hot pack, and the heat of the Chinese medicine hot pack is easily lost to the environment, and the duration of the hot compress is difficult to guarantee. If infrared devices and other equipment are used for auxiliary heating, it is necessary to consume equipment energy, which is not conducive to energy saving. Summary of the invention

In addition, one structural state of the heat preservation cavity and the support seat is a cylindrical shape, and the other structural states are truncated cones with different bottom diameters.

[0008] When the structural state of the heat preservation cavity and the support seat changes from a cylindrical shape to a truncated cone shape, and as the bottom diameter size continues to decrease, the gaps between the transverse threads in different groups of thread strips change; in any structural state of the heat preservation cavity and the support seat, at least one group of thread strips can match and connect the first connecting mechanism with the second connecting mechanism;

[0009] For example, when the structural state of the insulation cavity and the support seat changes from a cylindrical shape to a truncated cone shape, and as the bottom diameter size continues to decrease, the gap between the transverse threads in different groups of thread strips gradually decreases in order from top to bottom. In any structural state of the insulation cavity and the support seat, only one group of thread strips can match to connect the first connecting mechanism with the second connecting mechanism. The thread strips of other groups cannot connect the first connecting mechanism with the second connecting mechanism due to mismatch. The structural state of the insulation cavity and the support seat is limited by the first connecting mechanism and the second connecting mechanism connected together.

[0023] The present invention develops a device for palliative care, including a heat preservation cavity and a support seat. The heat preservation cavity is used to place a Chinese medicine hot pack and keep the hot pack warm. The support seat is connected to the bottom of the heat preservation cavity and is used to support the heat preservation cavity and the hot pack inside it to avoid direct contact with the patient and scalding the patient. The heat preservation cavity and the support seat are both adjustable structures that can be deformed from a cylindrical shape to a truncated cone shape. The present invention also defines the components for realizing the structural change, so that the size of the heat preservation cavity is adjustable to accommodate hot packs of Chinese medicine of different volumes.

[0032] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below in conjunction with specific embodiments and drawings.

[0033] In the description of the present invention, unless otherwise specified, all reagents used are commercially available and all methods used are conventional techniques in the art.

[0034] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0036] In view of the fact that the traditional Chinese medicine hot packs used in the palliative care analgesia process for cancer patients in the prior art are not well insulated, the heat of the traditional Chinese medicine hot packs is easily lost to the environment, and the duration of the hot compress is difficult to guarantee. If infrared devices and other equipment are used to assist heating, the energy of the equipment needs to be consumed, which is not conducive to energy saving. The present invention has developed a device for palliative care, see Figure 1 to Figure 4 The invention comprises a heat preservation cavity 1 and a support seat 2. The heat preservation cavity 1 is used for placing a Chinese medicine hot pack and keeping the hot pack warm. The support seat 2 is connected to the bottom of the heat preservation cavity 1 and is used to support the heat preservation cavity 1 and the Chinese medicine hot pack therein to prevent the hot pack from directly contacting the patient and scalding the patient.

[0037] Since the affected areas of different patients are of different sizes and the volumes of the Chinese medicine hot packs used are different, the practice of directly using thermal insulation materials to pack the Chinese medicine hot packs cannot meet the actual needs of palliative care and has little practical application value. In order to satisfy the requirements of keeping the Chinese medicine hot pack warm and avoiding scalding patients, meet the needs of different patients, and improve the practical value of the palliative care device of the present invention, in the present invention, the structures of the insulation cavity 1 and the support seat 2 are as follows: a first connecting mechanism 3 is arranged around the bottom of the side wall of the insulation cavity 1, and a second connecting mechanism 4 for connecting with the first connecting mechanism 3 is arranged around the bottom of the inner wall of the support seat 2. After the second connecting mechanism 4 is connected to the first connecting mechanism 3, the support seat 2 is connected to the bottom of the insulation cavity 1; the insulation cavity 1 and the support seat 2 can be deformed from a cylindrical shape to a truncated cone shape, and have multiple structural states. The first connecting mechanism 3 includes multiple groups of thread strips, and each group of thread strips contains multiple transverse threads; in each group of thread strips, there is a gap between adjacent transverse threads, and the number of structural states is equal to the number of groups of thread strips. One structural state of the insulation cavity 1 and the support seat 2 is a cylindrical shape, and the other structural states are truncated cones with different bottom diameters to achieve the function of adjusting the size. In different structural states of the heat preservation cavity 1 and the support seat 2, the connection parts of the first connection mechanism 3 and the second connection mechanism 4 are also different, so as to achieve the purpose of limiting the shape of the heat preservation cavity 1. For example, when the structural state of the heat preservation cavity 1 and the support seat 2 changes from a cylindrical shape to a truncated cone shape, and as the bottom diameter size continues to decrease, the gap between the transverse threads in different groups of thread strips changes; in any structural state of the heat preservation cavity 1 and the support seat 2, at least one group of thread strips can match and connect the first connection mechanism 3 and the second connection mechanism 4.

[0038] In summary, in order to solve the problems of the prior art, the present invention provides a device for palliative care that can not only keep the heat of the Chinese medicine hot pack warm, but also avoid scalding the patient, meet the needs of different patients, and improve the practical value. On the one hand, the hot compress duration of the Chinese medicine hot pack is guaranteed, and on the other hand, it avoids the use of infrared devices and other equipment for auxiliary heating, which helps to save energy.

[0039] Specifically, the more specific structure and working principle of the present invention are described through the following embodiments.

[0040] Example 1

[0041] A device for palliative care, see Figure 1 to Figure 5 The invention comprises a heat preservation cavity 1 and a support seat 2. The heat preservation cavity 1 is used for placing a Chinese medicine hot pack and keeping the hot pack warm. The support seat 2 is connected to the outer side of the bottom of the heat preservation cavity 1 and is used to support the heat preservation cavity 1 and the Chinese medicine hot pack inside the heat preservation cavity 1 to prevent the hot pack from directly contacting the patient and scalding the patient.

[0042] According to the actual usage habits of palliative care scenarios, the heat preservation cavity 1 and the support seat 2 are both set to a hollow structure, and the inner wall of the heat preservation cavity 1 is provided with a shelf component, such as a shelf net or a convex block 11, and the Chinese medicine hot pack is placed on the shelf component in the heat preservation cavity 1 to ensure that the Chinese medicine hot pack does not fall. It is also possible not to set a shelf component, and rely on the friction between the Chinese medicine hot pack and the heat preservation cavity 1 to prevent the Chinese medicine hot pack from falling.

[0043] Exemplarily, the shelf assembly is made of plastic, stainless steel, alloy or rope to meet the design and use requirements of the device.

[0044] It should be noted that, since the heat preservation cavity 1 and the support seat 2 are to be deformed between a cylindrical shape and a truncated cone shape, when the shelf component is a shelf net, it is made of a material such as a rope that can adapt to the deformation. When the shelf component is a convex block 11, refer to Figure 5 If the inner wall area of ​​the heat preservation cavity 1 occupied by the protrusion 11 is small, it can be made of hard materials such as stainless steel or alloy.

[0045] Exemplarily, the heat preservation cavity 1 includes a head end fixing device 12, a connector 13 and a tail end deformation device 14 connected in sequence, wherein the head end fixing device 12 is shown in FIG. Figure 2 , is annular, and the connector 13 is formed by connecting a columnar flexible material and a support strip 131 arranged on the side wall of the columnar flexible material. For example, the number of the support strips 131 is set to 3 to 15, which are distributed in an annular array around the central axis of the head end fixing device 12 and fixed to the outer wall of the columnar flexible material. Preferably, the columnar flexible material is a flexible material with a heat-insulating effect such as heat-insulating cotton, which is made into a columnar shape.

[0046] The tail end deformation device 14 includes a first bendable strip 142, which is arranged in a spiral shape. When the bendable strip 142 is squeezed, the first bendable strip 142 shrinks and its diameter becomes smaller, while the head end fixing device 12 has a constant diameter, so the heat preservation cavity 1 becomes as follows: Figure 3 In the frustum shown, the projection 11 is arranged on the inner wall of the inner ring of the first bendable strip 142, and at this time, the support strip 131 is connected to the first bendable strip 142. Preferably, the first bendable strip 142 is a coil spring or a helical bendable metal.

[0047] Further, in order to reduce the interference of the spiral shape to the outside world, the tail end deformation device 14 is shown in FIG. Figure 5 In addition to the first bendable strip 142, the first annular channel 141 is also included. The first bendable strip 142 is spirally arranged inside the first annular channel 141, and the protrusion 11 is arranged on the inner wall of the inner ring of the first annular channel 141. At this time, the support strip 131 is connected to the first annular channel 141. When the first annular channel 141 is squeezed, the first bendable strip 142 shrinks, and the diameter of the first annular channel 141 becomes smaller. Since the diameter of the head end fixing device 12 remains unchanged, the heat preservation cavity 1 will become as follows Figure 3 Preferably, the first annular channel 141 is made of flexible material, such as non-woven fabric, rubber and the like.

[0048] Exemplarily, the support base 2 includes a top deformation device 21, an intermediate body 22 and a bottom deformation device 23 connected in sequence, wherein the top deformation device 21 is Figure 6 , including a second annular channel 211 and a second bendable strip 212. The second bendable strip 212 is spirally distributed and located inside the second annular channel 211. The second annular channel 211 is connected to the top of the intermediate body 22, and the bottom deformation device 23 is shown in FIG. Figure 7 , including a retractable bracket 231, a plurality of rigid plates 221, such as 3 to 15, are provided on the inner side wall of the intermediate body 22, and the retractable bracket 231 is connected between the rigid plates 221 to adjust the distance between the rigid plates 221, thereby adjusting the shape of the support seat 2. Preferably, the second annular channel 211 is made of the same material as the first annular channel 141, the second bendable strip 212 is made of the same material as the first bendable strip 142, and the intermediate body 22 is made of the same material as the connecting body 13.

[0049] Exemplarily, the retractable bracket 231 is a compression spring, a tension spring or a pneumatic spring. A rigid plate 221 is respectively disposed at both ends of the retractable bracket 231.

[0050] A first connecting mechanism 3 is arranged around the lower end of the outer side wall of the insulation cavity 1, and a second connecting mechanism 4 is arranged around the upper end of the inner wall of the support seat 2. After the second connecting mechanism 4 is connected to the first connecting mechanism 3, the support seat 2 is connected to the bottom of the insulation cavity 1.

[0051] The first connecting mechanism 3 includes multiple groups of thread strips, each group of thread strips includes multiple transverse threads, and in each group of thread strips, there are gaps between adjacent transverse thread strips. When the insulation cavity 1 and the support seat 2 are in different structural states, the sizes of these gaps also change.

[0052] The second connection mechanism 4 is a complete set of threads, which can be connected to any set of thread bars; or, the second connection mechanism 4 includes a plurality of thread bars of the same number as the first connection mechanism 3, and any set of corresponding thread bars can be connected.

[0053] Exemplarily, the multiple groups of threaded bars of the first connecting mechanism 3 include a first group of threaded bars 31 and a second group of threaded bars 32, the gap between the multiple transverse threads in the first group of threaded bars 31 is a first vertical spacing 311, the gap between the multiple transverse threads in the second group of threaded bars 32 is a second vertical spacing 321, and the structural states of the insulation cavity 1 and the support seat 2 include cylindrical and truncated cone shapes; when the structural states of the insulation cavity 1 and the support seat 2 are both cylindrical, the insulation cavity 1 and the support seat 2 are connected through the first group of threaded bars 31, but not connected to the second group of threaded bars 32, and at this time the size of the first vertical spacing 311 is smaller than the size of the second vertical spacing 321; when the structural states of the insulation cavity 1 and the support seat 2 are both truncated cone shapes, the insulation cavity 1 and the support seat 2 are connected through the second group of threaded bars 32, but not connected to the first group of threaded bars 31.

[0054] Preferably, in order to facilitate the connection, when the structural states of the heat preservation cavity 1 and the support seat 2 are both Figure 1 The cylindrical shape shown in the figure has a first vertical spacing 311 size of 1 mm to 3 mm, and a vertical spacing 321 between a plurality of thread strips in a second vertical spacing 321 is 4 mm to 6 mm; when the structural states of the heat preservation cavity 1 and the support seat 2 are both Figure 3 In the frustum-conical shape shown, the vertical spacing 321 between the plurality of thread strips in the second vertical spacing 321 is changed to 1 mm to 3 mm.

[0055] In order to facilitate the matching connection between the first connection mechanism 3 and the second connection mechanism 4, when the second connection mechanism 4 is a complete set of threaded strips, in each structural state of the heat preservation cavity 1, the second connection mechanism 4 can only be connected to a set of threaded strips of the first connection mechanism 3, and the remaining threaded strips of the first connection mechanism 3 will have thread slippage with the second connection mechanism 4 due to the limitation of "different gaps between transverse threads in different groups of threaded strips", so that they cannot be matched and connected with the second connection mechanism 4. In addition, when the second connection mechanism 4 also includes multiple sets of threaded strips, in each structural state of the heat preservation cavity 1, only one set of threaded strips corresponding to the first connection mechanism 3 and the second connection mechanism 4 can be matched and connected, so as to achieve the purpose of limiting the shape of the heat preservation cavity 1, and the threaded strips of other groups cannot be matched and connected due to the limitation of different gaps between transverse threads in different groups of threaded strips.

[0056] In order to better adjust the gap between the transverse threads in different groups of thread strips, for example, to facilitate the adjustment of the sizes of the first vertical spacing 311 and the second vertical spacing 321, the first group of thread strips 31 and the second group of thread strips 32 are arranged on the outer wall of the support strip 131, the first group of thread strips 31 and the second group of thread strips 32 are arranged using the rigid support strip 131, and the second connecting mechanism 4 is arranged on the inner wall of the rigid plate 221.

[0057] Based on the above structural description, the heat preservation cavity 1 and the support seat 2 can be deformed from a cylindrical shape to a truncated cone shape, and have multiple structural states. One structural state of the heat preservation cavity 1 and the support seat 2 is a cylindrical shape, and the other structural states are truncated cones with different diameters to achieve the function of adjusting the size. In different structural states of the heat preservation cavity 1 and the support seat 2, the connection parts of the first connecting mechanism 3 and the second connecting mechanism 4 are also different. As a result, the present invention provides a palliative care device that can not only keep the heat of the traditional Chinese medicine hot pack warm, but also avoid scalding the patient, meet the needs of different patients, and improve the practical value. On the one hand, the hot compress duration of the traditional Chinese medicine hot pack is guaranteed, and on the other hand, it avoids the use of infrared devices and other equipment for auxiliary heating, which helps to save energy.

[0058] It should be noted that the component connection relationships not specifically mentioned in the present invention are assumed to adopt the existing technology. Since they do not involve the invention point and are widely used in the existing technology, the structural connection relationships are not described in detail.

[0059] It should be noted that when the present invention involves a numerical range, it should be understood that the two endpoints of each numerical range and any value between the two endpoints can be selected. Since the steps and methods used are the same as those in the embodiments, in order to avoid redundancy, the present invention describes a preferred embodiment. Although the preferred embodiments of the present invention have been described, once those skilled in the art know the basic inventive concept, they can make other changes and modifications to these embodiments, and these changes and modifications all fall within the scope of the present invention.
