Description

Technical Field

[0001] This utility model relates to auxiliary tools for scalp care and treatment, and in particular to a combined dispensing device. In recent years, with the continuous advancement of diagnostic and treatment methods, in addition to traditional drugs, various types of physical phototherapy have also been widely used in the treatment of scalp and hair diseases. Background Technology

[0002] Scalp and hair diseases are common in dermatology. Seborrheic dermatitis, scalp psoriasis, and other scalp conditions have long courses and are prone to recurrence, causing significant disruption to patients' lives. In clinical treatment, the efficiency of physical phototherapy is affected by various factors. Besides the irradiation power and duration, the degree of lesion exposure is also a crucial factor. Only when the light beam directly irradiates the scalp can it achieve the maximum therapeutic effect. However, in clinical practice, we have found that due to hair obstruction, the light beam rarely reaches the scalp directly, limiting the irradiation effect. For male patients, shaving can increase the exposure of the lesions, but for female patients, cutting or shaving their hair severely affects their appearance, which is often unacceptable. Therefore, it is essential to invent a distribution device that can separate and fix the hair to expose the scalp requiring phototherapy, and that can be adjusted according to the location and area of ​​different lesions on the head.

[0004] The modular dispensing device consists of two headband rods and four side components.

[0005] The headband rod is shaped like a headband, with the entire rod having the same diameter and a certain degree of resilience.

[0006] The side components are made of rubber in one piece and are in the shape of a long column. Positioning through holes are arranged at intervals on the column and pass through the upper and lower sides of the column. A rod sleeve is fixed on the left side of the column. The center line of the hole of the rod sleeve is parallel to the length direction of the column and perpendicular to the center line of each positioning through hole. The hole of the rod sleeve is used to fit the shaping rod. First, the two side components are passed through the corresponding positioning through holes and fitted onto the upper middle part of the two headband rods. Then, a side component is passed through each end of the two headband rods.

[0007] Furthermore, it also includes at least two shaping rods; the shaping rods are rods made of metal.

[0008] Furthermore, the shaping rod is inserted into the sleeve hole of the side component rod sleeve body.

[0009] Furthermore, the shaping rod is inserted into the sleeve holes of the two side component rod sleeves located at both ends of the headband rod.

[0010] Furthermore, it is also equipped with a horizontal edge assembly, which includes a main body with a flat bottom surface, and a protruding rod sleeve part in the middle of the upper surface of the main body. The sleeve hole of the rod sleeve part is used to fit the headband rod.

[0011] Furthermore, the required number of transverse side components are fitted onto the rod body between the two side components in the upper part of the headband rod, with the transverse side components on the same side arranged sequentially along the extension direction of the headband rod body.

[0012] Furthermore, the sleeve portion is located on the upper surface of the main body at the middle of the rear edge of the main body.

[0013] Furthermore, positioning grooves are formed on the main body on both sides of the rod sleeve to help the hairband rod be inserted and limited.

[0014] Furthermore, multiple friction-enhancing strips are formed on the bottom surface of the horizontal component main body, arranged at intervals and extending in a direction parallel to the length of the main body.

[0015] Furthermore, multiple friction-enhancing strips are formed on the columnar side of the side assembly that faces away from the rod sleeve body. These strips are spaced apart and extend in a direction parallel to the length of the columnar body.

[0028] Unless otherwise explicitly stated and limited, the terms “set up,” “install,” and “connect” should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a direct connection or an indirect connection through an intermediate medium.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Figure 1 and Figure 2 The first embodiment of this utility model is shown. In this embodiment, the components of this utility model include two headband rods 1, four side components 2, and two shaping rods 3.

[0031] The headband rod 1 is shaped like a regular headband. The entire rod has a uniform diameter and rounded ends to prevent scratches. It is made of metal or hard plastic with some elasticity to ensure it fits comfortably on the head and is suitable for most head sizes. However, it does not directly contact the scalp; instead, components threaded onto it press and separate the hair while contacting the head. The uniform diameter of the rod facilitates adjustment of the components as they move along the rod.

[0032] The side component 2 is in the shape of a long column and is made of rubber material with a certain degree of elasticity and resistance to a certain degree of high temperature. Positioning through holes 21 are arranged at intervals on its columnar body and pass through the upper and lower columnar sides respectively. A rod sleeve 22 is fixed on the left columnar side. The center line of the hole 221 of the rod sleeve 22 is parallel to the length direction of the columnar body and perpendicular to the center line of each positioning through hole 21. The hole 221 of the rod sleeve 22 is used to fit the shaping rod 3.

[0033] This embodiment uses a combination of methods:

[0034] First, assemble the two side components that are not fitted with the shaping rod 3 (such as...). Figure 1 2a and 2b) are threaded onto the two headband rods 1, and then a side component (such as...) is threaded onto each end of the two headband rods 1. Figure 1 (2c, 2d);

[0035] Two positioning through holes 21 at appropriate positions are selected for each side component to pass through the corresponding headband rod 1, so as to ensure that the distance between the two parallel headband rods 1 is not less than the maximum longitudinal distance of the scalp lesion area that needs to be treated with light. For example, in this embodiment, the two headband rods 1 pass through the second and fifth positioning through holes 21 of the same side component 2, respectively, and the interval between the two headband rods 1 is equivalent to three times the spacing between the positioning through holes.

[0036] The two side components located in the upper middle part (such as) Figure 1 The spacing between 2a and 2b) should not be less than the maximum lateral distance of the scalp lesion area requiring phototherapy. These two side components are responsible for pressing down the hair on both sides of the lesion area laterally (left and right sides on the drawing). Specifically, the right columnar side of the side component is used to press down the hair, keeping it separated and fully exposing the lesion area. This is suitable for cases where the lesion area is long and narrow. In such cases, only the two side components need to press down the hair on both sides of the lesion area. Since the width at both ends of the lesion area is relatively narrow, the hair at both ends can be directly pressed diagonally onto the two side components.

[0037] The two side components located at both ends of the headband rod 1 (such as...) Figure 1 The functions of 2c and 2d are: firstly, to work with the two side components in the upper middle part to maintain the parallel posture and spacing of the two headband rods; secondly, to avoid the discomfort caused by the headband rods pressing directly on the head, so that the softer side components with a larger contact area contact the sides of the head, thus improving the comfort of the patient.

[0038] Since the side assembly is made of a soft rubber material with a certain degree of elasticity, it is easy to adjust its relative position to the headband rod 1. The curvature of the headband rod 1 also allows the positioning through hole 21 of the side assembly to have a certain interference fit with the rod body, thereby increasing the friction between them. As a result, the side assembly can maintain the stability of its position relative to the rod body after manual adjustment.

[0039] Preferably, multiple friction-enhancing strips 23 are formed on the right column side of the side component (i.e. the column side opposite to the rod sleeve body 22) and extend in a direction parallel to the length of the column, so as to increase the friction with the hair being pressed.

[0040] The function of the shaping rod 3 is to help the corresponding side component 2 maintain its straight shape and posture by using its rigidity, which is made of metal or hard plastic, after it is inserted into the sleeve hole 221 of the rod sleeve body 22 of the side component 2, thereby helping to maintain the relative posture of the two headband rods.

[0041] Figure 4 and Figure 5 The following is a second embodiment of the present invention. In this embodiment, a horizontal component 4 is added to the components of the present invention. The horizontal component 41 includes a main body 41 with a flat bottom surface. A protruding rod sleeve portion 42 is provided in the middle of the upper surface of the main body 41. The sleeve hole of the rod sleeve portion 42 is used to fit the headband rod 1. The required number of horizontal components 4 are fitted on the headband rod 1 between the two side components 2 in the upper middle part. The horizontal components 4 on the same side are arranged sequentially along the extension direction of the headband rod. The rod sleeve portion 42 faces the lesion area. The main body 41 is used to press down the hair on the corresponding side.

[0042] Furthermore, the sleeve portion 42 is located at the middle of the upper surface of the main plate 41, near the rear edge of the main plate 41, while the front plate 411 is selected with an appropriate delay, thereby increasing the effective area and avoiding invasion into the damaged area. Moreover, since the sleeve portion 42 is a protrusion located in the middle of the main plate 41, the main plate 41 on both sides of the sleeve portion 42 in the direction of the center of the sleeve hole naturally presses down on the hair on the corresponding side using the headband rod. This structure also shortens the length of the sleeve portion 42, avoiding excessive length that would make it too difficult to fit and move on the headband rod.

[0043] Furthermore, in order to ensure that the headband rod can be pressed down stably and avoid detachment, positioning grooves 43 are formed on the main body 41 on both sides of the rod sleeve 42 to limit the insertion of the headband rod. The above function is achieved through the cooperation between the groove wall 430 and the headband rod 1.

[0044] Preferably, multiple friction-enhancing strips (not shown in the figure) are also formed on the bottom surface of the main body 41 of the horizontal edge component 4 in a spaced-apart manner and extending in a direction parallel to the length direction of the main body, so as to increase the friction with the hair being pressed.

[0045] like Figure 5 As shown, the side component is responsible for pressing down the hair on the horizontal sides (left and right sides in the drawing) of the lesion area, while the horizontal component 4 is responsible for pressing down the hair on the vertical sides (front and back sides in the drawing) of the lesion area. The number of horizontal components 4 sets depends on the length of the side, making this utility model more versatile and flexible.

[0046] It should be noted that, Figures 1 to 5 This invention is shown in two common usage scenarios: the two headband rods 1 are in a relatively parallel posture, and only on the two side components located at both ends of the headband rods 1 (such as...). Figure 1 The 2c and 2d sections are equipped with a shaping rod 3, and the shaping rod 3 is straight. However, there are actually other special use cases, including but not limited to the following:

[0047] To accommodate lesion areas with special shapes, the two headband rods 1 need to be tilted towards each other. For example, the distance between the two headband rods 1 needs to gradually increase from both ends to the middle. The side components (2c, 2d) at both ends pass through the headband rods 1 through their respective third and fourth positioning through holes, and the two side components (2a, 2b) in the upper middle part pass through the headband rods 1 through their respective first and sixth positioning through holes. In order to prevent the side components in the upper middle part from bending under force and failing to maintain their shape effectively, the two side components can also be fitted with shaping rods 3.

[0048] When a side component needs to be non-straight, a shaping rod is fitted onto the side component at that location, and the shaping rod is bent into the required shape, thereby forming and maintaining the desired shape of the side component.

[0049] Furthermore, the upper side components can be used upside down, with the sleeve 22 facing the head. Since the sleeve 22 does not have a fitted shaping rod, its elasticity allows it to better adapt to certain bumps on the scalp (such as pimples), minimizing pressure and increasing comfort.

[0050] When the sleeve body 22 is used with the head facing it, the smaller and narrower effective area of ​​the sleeve body 22 compared to the effective area of ​​the column side away from the sleeve body 22 can be used to meet the needs of the corresponding usage scenarios.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
