Description

Technical Field

[0001] This invention relates to the field of hair follicle preservation devices, specifically a hair follicle preservation device for hair transplantation. Background Technology

[0002] Like other tissues, human hair is transplantable. Hair transplantation can effectively solve hair loss problems such as baldness and alopecia. The transplantation process typically involves extracting hair follicles and surrounding tissue using specialized instruments, pre-processing them, and then implanting them into suitable locations on the scalp. Currently, autologous hair transplantation is widely used clinically. This technique employs minimally invasive microsurgical methods, usually selecting healthy hair follicles from the back of the patient's head (due to their inherently intact structure and minimal influence from androgens, resulting in a high survival rate after transplantation). After meticulous separation and cryopreservation, these follicles are then transplanted to bald or other areas of hair loss. Once the transplanted follicles survive, they can grow new hair with the original biological characteristics and growth indicators, thereby supplementing the amount of hair and modifying the local distribution pattern, fundamentally improving the patient's hair problems.

[0003] Hair follicles have extremely limited survival rate after being removed from the body, with an optimal preservation time of only about four hours. Furthermore, the suitable preservation temperature for removed hair follicles must be strictly controlled between 0℃ and 4℃. Current methods for hair follicle preservation often employ simple refrigeration: using ice packs as a cooling base, with a storage box placed on top to hold the hair follicle tissue. While this method can preserve hair follicles to some extent, it still has significant drawbacks: First, hair transplant surgery is typically lengthy, and ice packs are prone to melting, causing temperature fluctuations and making it difficult to maintain a stable low temperature range. This necessitates frequent monitoring and replacement of ice packs by medical staff, increasing operational complexity. Second, existing preservation devices cannot adjust preservation conditions for different types of hair follicles (such as coarse vs. fine hair, healthy vs. follicles in balding areas), resulting in poor adaptability. Third, existing preservation devices are mostly one-piece structures, requiring the lid to be fully opened when removing or placing hair follicles. Frequent opening and closing not only introduces temperature fluctuations but may also affect hair follicle activity due to external environmental interference, reducing the success rate of transplantation. Summary of the Invention

[0004] This invention aims to provide a hair follicle preservation device for hair transplantation. Different types of hair follicles are contained in different test tubes, and each test tube containing the detached hair follicles is independently placed in a cooling cylinder. A self-adjusting component adjusts the cooling power according to the overall weight / mass of the test tubes, effectively ensuring the activity of the detached hair follicles during preservation. This solves the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A hair follicle preservation device for hair transplantation includes a preservation box and several test tubes. The preservation box is rotatably connected to a handle, and the test tubes are used to hold excised hair follicles. The preservation box is detachably connected to several independent sub-boxes. Each sub-box is connected to a cover, a preservation base, and a battery. The preservation base and the battery are electrically connected via a self-adjusting component. The preservation base and the self-adjusting component are located inside the preservation chamber of each sub-box. The cover is rotatably connected to the sub-box to open and / or close the preservation chamber. The adjustment assembly includes a resistor, a slider, and a linkage spring. The resistor is fixedly connected to the inner wall of the sub-box, and the storage base is connected to the inner bottom wall of the sub-box via the linkage spring. The storage base and the resistor are slidably connected via the slider. The storage base is fixedly connected to a refrigeration cylinder, and the test tube is placed inside the refrigeration cylinder. The slider, resistor, refrigeration cylinder, and battery are connected via electrical wires, and the refrigeration power of the refrigeration cylinder is linearly related to the sliding distance of the slider relative to the resistor.

[0007] Furthermore, the inner bottom wall of the sub-box is connected to a conductive groove, and the outer bottom wall of the storage base is connected to a conductive protrusion that cooperates with the conductive groove. The linkage spring is sleeved on the outside of the conductive groove and the conductive protrusion. The outer side of the cover is connected to a display panel that is connected to the battery via an electrical wire. The conductive groove and the conductive protrusion are electrically connected to the two ends of the display panel, and the contact between the conductive groove and the conductive protrusion makes the display panel form a circuit and display refrigeration information.

[0008] Furthermore, the refrigeration information displayed on the display panel includes whether refrigeration is present and the refrigeration temperature; wherein the refrigeration temperature is 0℃~4℃.

[0009] Furthermore, the inner side of the sub-box is connected to a clamping assembly for clamping and fixing the test tube. The clamping assembly includes a fixing block fixedly connected to the inner wall of the sub-box. The fixing block is connected to a clamping plate via a clamping spring. The end of the clamping plate away from the clamping spring abuts against the outer wall of the test tube.

[0010] Furthermore, both the preservation substrate and the cooling cylinder are cylindrical, the cooling cylinder is fixedly connected to the inner side of the preservation substrate, and the outer diameter of the cooling cylinder is equal to the inner diameter of the preservation substrate, and the outer diameter of the test tube is equal to the inner diameter of the cooling cylinder.

[0011] Furthermore, there are four self-adjusting components and four clamping components, and the four self-adjusting components and four clamping components are evenly arranged around the central axis of the storage substrate.

[0012] Furthermore, the slider is fixedly connected to the storage substrate, the resistor has a through groove, and the slider slides through the through groove.

[0013] Furthermore, both the resistor and the clamping plate are provided with arc-shaped portions, and the diameter of the arc-shaped portion of the resistor is consistent with the outer diameter of the storage substrate, and the diameter of the arc-shaped portion of the clamping plate is consistent with the outer diameter of the test tube.

[0014] Furthermore, a heat insulation layer is connected to one side of the cover near the sub-box, and the heat insulation layer is a rigid polyurethane foam with aluminum foil bonded to its surface.

[0015] Furthermore, the cover is connected to a handle on the side away from the sub-box, and both the handle and the carrying handle are covered with anti-slip sleeves.

[0016] The principles and beneficial effects of the technical solution are as follows:

[0017] 1. This invention provides a hair follicle preservation device for hair transplantation, comprising a preservation box and several test tubes. The preservation box has several independent sub-boxes, each containing different types of hair follicles. Each sub-box is connected to a cover, a preservation substrate, and a battery. The preservation substrate is connected to a cooling cylinder. Test tubes containing detached hair follicles are placed one-to-one within the cooling cylinder. Removing or inserting hair follicles simply requires opening the cover of the corresponding sub-box, avoiding temperature fluctuations caused by opening the lid in a monolithic structure and reducing the impact of the external environment on hair follicle activity. The preservation substrate and the battery are electrically connected via a self-adjusting component, which includes a resistor, a slider, and a linkage spring. The preservation substrate and sub-boxes are connected via a linkage spring, and the preservation substrate and resistor are slidably connected via a slider. The cooling cylinder... The cooling power is linearly related to the sliding distance of the slider relative to the resistive element. That is, the slider and the resistive element constitute a sliding rheostat. The cooling cylinder is electrically connected to the battery through the sliding rheostat. By adjusting the effective resistance of the sliding rheostat, the cooling power of the cooling cylinder can be adjusted. When a test tube containing detached hair follicles is placed in the cooling cylinder, the different types of hair follicles (such as coarse hair and fine hair, healthy hair follicles and hair follicles in balding areas) have different requirements for the amount of preservation solution, resulting in different weights / masses of the entire test tube. This causes different pressures on the linkage spring, which in turn causes different deformations of the linkage spring, resulting in different sliding distances of the slider relative to the resistive element. This allows for adaptive adjustment of the cooling power, further improving the preservation effect of detached hair follicles (ensuring the activity of detached hair follicles during preservation).

[0018] 2. This invention provides a hair follicle preservation device for hair transplantation. A sub-box is connected to a conductive groove, a preservation substrate is connected to conductive protrusions, and a cover is connected to a display panel. The conductive groove and conductive protrusions are electrically connected to the two terminals of the display panel, and the contact between the conductive groove and conductive protrusions creates a circuit on the display panel, displaying refrigeration information. When no detached hair follicles are preserved, the conductive groove and conductive protrusions are disconnected, and the display panel is in an open-circuit state, displaying no information. When a test tube containing detached hair follicles is placed inside a refrigeration cylinder, the linkage spring is compressed under pressure, and the contact between the conductive groove and conductive protrusions causes the display panel to display refrigeration information. The refrigeration information displayed on the display panel includes whether refrigeration exists and the refrigeration temperature. The refrigeration temperature is 0℃~4℃, allowing operators to intuitively know whether detached hair follicles are preserved inside the corresponding sub-box, and to preliminarily determine the type of preserved hair follicles based on the temperature difference.

[0019] 3. This invention provides a hair follicle preservation device for hair transplantation. The inner side of the sub-box is connected to a clamping assembly. The clamping assembly includes a fixing block, which is connected to a clamping plate via a clamping spring. The end of the clamping plate away from the clamping spring abuts against the outer wall of the test tube. The clamping assembly clamps and fixes the test tube, ensuring the stability of the test tube during transport and preventing shaking, thus further reducing the impact on the activity of the isolated hair follicles. Both the preservation substrate and the cooling cylinder are cylindrical, with the outer diameter of the cooling cylinder equal to the inner diameter of the preservation substrate, and the outer diameter of the test tube equal to the inner diameter of the cooling cylinder. There are four self-adjusting components and four clamping components, all evenly arranged around the central axis of the preservation substrate, further improving the clamping and fixing effect on the test tube.

[0020] 4. This invention provides a hair follicle preservation device for hair transplantation. A slider is fixedly connected to the preservation substrate. A resistor has a through groove, through which the slider slides. During the placement of the test tube and compression of the linkage spring, the slider and through groove guide and limit the movement of the preservation substrate relative to the resistor, ensuring the uniformity and stability of the relative movement of the two (preservation substrate and resistor), thereby improving the functionality and stability of the entire device. Both the resistor and the clamping plate have arc-shaped portions. The diameter of the arc-shaped portion of the resistor is the same as the outer diameter of the preservation substrate, and the diameter of the arc-shaped portion of the clamping plate is the same as the outer diameter of the test tube. This results in good adhesion between the resistor and the preservation substrate, and between the clamping plate and the test tube, further improving the stability of the entire device.

[0021] 5. The hair follicle preservation device for hair transplantation provided by the present invention has a heat insulation layer connected to the side of the cover near the sub-box. The heat insulation layer can reduce the exchange of hot air between the inside of the sub-box and the outside environment, and improve the refrigeration effect. The heat insulation layer is a rigid polyurethane foam with aluminum foil bonded to the surface, which is easy to clean and disinfect, and reduces cross-contamination between test tubes during repeated use. A handle is connected to the side of the cover away from the sub-box. The handle and the outside of the handle are covered with anti-slip sleeves, which effectively improves the convenience of operation. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0031] like Figures 1 to 6As shown, a hair follicle preservation device for hair transplantation includes a preservation box 1 and four test tubes 15. The preservation box 1 is rotatably connected to a handle 3. The four test tubes 15 are used to hold different types of detached hair follicles.

[0032] The inner bottom wall of the sub-box 2 is connected to a conductive groove 12, and the outer bottom wall of the storage base 6 is connected to a conductive protrusion 13 that cooperates with the conductive groove 12. A linkage spring 14 is sleeved on the outside of the conductive groove 12 and the conductive protrusion 13. The outer side of the cover 4 is connected to a display panel 16 that is connected to the battery 10 through an electrical wire. The conductive groove 12 and the conductive protrusion 13 are electrically connected to the two ends of the display panel 16, and the contact between the conductive groove 12 and the conductive protrusion 13 makes the display panel 16 form a circuit and display refrigeration information. The refrigeration information displayed on the display panel 16 includes whether refrigeration is present and the refrigeration temperature, which is 0℃~4℃.

[0033] The inner wall of the sub-box 2 is connected to a clamping assembly 17 for clamping and fixing the test tube 15. The clamping assembly 17 includes a fixing block 18 fixedly connected to the inner wall of the sub-box 2. The fixing block 18 is connected to a clamping plate 20 through a clamping spring 19. The end of the clamping plate 20 away from the clamping spring 19 abuts against the outer wall of the test tube 15.

[0034] In addition, in this embodiment, both the preservation substrate 6 and the cooling cylinder 11 are cylindrical. The cooling cylinder 11 is fixedly connected to the inner side of the preservation substrate 6, and the outer diameter of the cooling cylinder 11 is equal to the inner diameter of the preservation substrate 6. The outer diameter of the test tube 15 is equal to the inner diameter of the cooling cylinder 11. There are four self-adjusting components and four clamping components 17, and the four self-adjusting components and four clamping components 17 are evenly arranged around the central axis of the preservation substrate 6.

[0035] The slider 9 is fixedly connected to the storage substrate 6. The resistor 7 has a through groove 8, and the slider 9 slides through the through groove 8. Both the resistor 7 and the clamping plate 20 have arc-shaped parts, and the diameter of the arc-shaped part of the resistor 7 is consistent with the outer diameter of the storage substrate 6, and the diameter of the arc-shaped part of the clamping plate 20 is consistent with the outer diameter of the test tube 15.

[0036] The specific implementation process is as follows:

[0037] When using this hair follicle preservation device, first, place different types of hair follicles (coarse and hard hair, fine and soft hair, healthy hair follicles, and hair follicles from balding areas) into the corresponding test tubes 15, and add preservation solution according to the preservation requirements of the hair follicles; then, use the handle 5 to turn and open the cover 4, insert the test tube 15 into the refrigeration cylinder 11 (the outer bottom wall of the test tube 15 abuts against the inner bottom wall of the refrigeration cylinder 11); finally, use the cover 4 to close the preservation chamber of the sub-box 2, thus completing the preservation of detached hair follicles; during preservation, the operator can choose to determine whether hair follicles are preserved in the corresponding sub-box 2 by checking whether the display panel 16 shows refrigeration information and / or refrigeration temperature, and can preliminarily determine the type of hair follicles preserved in the sub-box 2. When it is necessary to transport the entire device, the handle 3 can be selected to facilitate the transportation of the entire preservation box 1.

[0038] Different types of hair follicles are contained in different test tubes 15. Each test tube containing detached hair follicles is placed in a corresponding cooling cylinder 11. When removing or placing hair follicles, the corresponding sub-box 2 can be opened, avoiding temperature fluctuations caused by opening the lid of the integrated structure and reducing the impact of the external environment on hair follicle activity. When the test tubes containing detached hair follicles are placed in the cooling cylinder 11, the different requirements of different types of hair follicles (such as coarse hair and fine hair, healthy hair follicles and hair follicles in balding areas) for the amount of preservation solution result in different weights / masses of the entire test tube 15. This causes different pressures on the linkage spring 14, resulting in different deformations of the linkage spring 14. Consequently, the sliding distance of the slider 9 relative to the resistive element 7 varies, achieving adaptive adjustment of the cooling power and further improving the preservation effect of detached hair follicles (ensuring the activity of detached hair follicles during preservation).

[0039] Sub-box 2 is connected to conductive groove 12, storage base 6 is connected to conductive protrusion 13, and cover 4 is connected to display panel 16. Conductive groove 12 and conductive protrusion 13 are electrically connected to the two terminals of display panel 16, and the contact between conductive groove 12 and conductive protrusion 13 makes display panel 16 form a circuit and display refrigeration information. When no detached hair follicles are stored, conductive groove 12 and conductive protrusion 13 are disconnected, and display panel 16 is in an open circuit state and does not display any information. When test tube 15 containing detached hair follicles is placed in refrigeration cylinder 11, linkage spring 14 is compressed under pressure, and conductive groove 12 and conductive protrusion 13 contact, making display panel 16 display refrigeration information. The refrigeration information displayed on display panel 16 includes whether refrigeration exists and refrigeration temperature. The refrigeration temperature is 0℃~4℃, which makes it easy for operators to intuitively know whether detached hair follicles are stored inside the corresponding sub-box 2, and can preliminarily determine the type of stored hair follicles by the temperature difference.

[0040] The inner side of the sub-box 2 is connected to the clamping assembly 17, which clamps and fixes the test tube 15 to ensure the stability of the test tube 15 during transportation and to prevent shaking of the test tube 15 during transportation, thereby further reducing the impact on the activity of the isolated hair follicles. The slider 9 is fixedly connected to the preservation substrate 6. The resistor 7 has a through groove 8, and the slider 9 slides through the through groove 8. During the compression of the linkage spring 14 when the test tube 15 is placed, the slider 9 and the through groove 8 guide and limit the movement of the preservation substrate 6 relative to the resistor 7, ensuring the uniformity and stability of the relative movement of the two (preservation substrate 6 and resistor 7), thereby improving the functionality and stability of the entire device. Both the resistor 7 and the clamping plate 20 are provided with arc-shaped parts. The diameter of the arc-shaped part of the resistor 7 is consistent with the outer diameter of the storage substrate 6, and the diameter of the arc-shaped part of the clamping plate 20 is consistent with the outer diameter of the test tube 15. This makes the fit between the resistor 7 and the storage substrate 6, and between the clamping plate 20 and the test tube 15 good, which can further improve the stability of the entire device.

[0041] A heat insulation layer 21 is connected to the side of the cover 4 near the sub-box 2. The heat insulation layer 21 can reduce the exchange of hot air between the inside of the sub-box 2 and the outside environment, and improve the refrigeration effect. The heat insulation layer 21 is a rigid polyurethane foam with aluminum foil bonded to the surface, which is easy to clean and disinfect, and reduces cross-contamination between test tubes 15 when reused. A handle 5 is connected to the side of the cover 4 away from the sub-box 2. The handle 5 and the handle 3 are both covered with anti-slip sleeves, which effectively improves the convenience of operation.

[0042] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific technical solutions or characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
