Description

Technical Field

[0001] This utility model relates to the field of hair transplantation instruments, and in particular to a low-temperature storage device for hair follicle units. Background Technology

[0002] Currently, over 250 million people in my country face hair loss issues, meaning that on average, one in six people suffers from hair loss. Hair loss is showing a trend towards affecting younger and younger people, primarily between the ages of 20 and 40, with the fastest progression around age 30 – 20 years earlier than the previous generation.

[0003] As hair loss becomes increasingly serious, hair transplantation has become widely accepted. During hair transplantation, hair follicle units are often extracted from the back of the head. After medical staff process the hair follicle units, separating them into single or double hairs, they are then transplanted.

[0004] The "Expert Consensus on Clinical Application of Hair Transplantation Technology" and the "Hair Transplantation Standards" mention that the separation process should be carried out in a low-temperature, humid environment to prevent hair follicle dehydration. Hair transplantation is an extremely time-consuming surgical procedure, and maintaining the activity of hair follicles outside the body is the core issue in improving the survival rate of hair follicles.

[0005] Regarding storage temperature, studies have confirmed that low temperatures can reduce metabolic activity within hair follicle cells and decrease cell death. Therefore, it is recommended that hair follicles be stored at low temperatures outside the body. Expert consensus suggests that hair follicles be stored in an absolutely humid state at low temperatures (preferably 0-4°C), and the shorter the storage time, the more beneficial it is for hair follicle growth.

[0006] Regarding preservation time, studies have confirmed that the activity of detached hair follicles gradually decreases with prolonged in vitro preservation time, and the in vitro preservation time is best controlled within 6 hours. To reduce the time hair follicles are detached from the body, it is recommended to implant them in the order in which they were extracted, that is, to implant the hair follicles that were extracted earlier, and to minimize the preservation time of the hair follicles in vitro.

[0007] In clinical practice, the separated hair follicle units are typically placed on gauze pads soaked in low-temperature sterile saline solution, and these gauze pads are then stored in containers filled with ice. This method of preserving hair follicle units makes it difficult to effectively control the storage temperature, resulting in poor effectiveness in maintaining the units at a low temperature. Furthermore, because the hair follicle units are in direct contact with ice or ice water, the risk of contamination is also relatively high. Utility Model Content

[0008] The purpose of this invention is to provide a low-temperature storage device for hair follicle units, which not only improves the effect of keeping hair follicle units at a low temperature, but also reduces the risk of hair follicle units being contaminated.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A low-temperature storage device for hair follicle units includes a storage base, a storage disk, and a support disk;

[0011] The storage base includes a housing and a semiconductor cooling system, wherein:

[0012] The casing is a shell structure with an opening on the top surface. A partition plate is provided in the casing to divide the inner cavity of the casing into a lower equipment cavity and an upper refrigeration cavity.

[0013] The semiconductor cooling system includes a temperature control component and a heat sink. The temperature control component is located in the equipment cavity of the housing and its cold end ceramic plate is embedded and fixed in the partition plate. The heat sink is fixed on the side wall of the housing corresponding to its equipment cavity and is connected to the equipment cavity of the housing.

[0014] The storage disk is adapted to the cooling cavity of the casing, and the storage disk is provided with a partition plate to evenly divide the inner cavity of the storage disk into several cooling zones.

[0015] The number of carrier disks is consistent with the number of cooling zones in the storage disk, and the carrier disks and cooling zones are compatible.

[0016] Furthermore, it also includes a control box, which is fixed to the housing. The control box has a control display screen and a power supply inside. The temperature control components, heat sink, and power supply are all electrically connected to the control display screen.

[0017] Furthermore, each storage disk or partition corresponding to a cooling zone has a serial number label on its top surface, which is used to identify different cooling zones in sequence.

[0018] Furthermore, the cold end ceramic plate of the temperature control component is flush with the upper side of the partition plate, or the cold end ceramic plate of the temperature control component is higher than the upper side of the partition plate.

[0019] Furthermore, both the storage disk and the carrier disk are made of stainless steel.

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] Please see Figures 1-4 As shown, a low-temperature storage device for hair follicle units includes a storage base, a storage disk 9, and a support disk 11.

[0034] The storage dock includes a housing 1 and a semiconductor cooling system, wherein:

[0035] The housing 1 is a shell structure with an opening on the top surface. The housing 1 is provided with a partition plate 2, which divides the inner cavity of the housing 1 into a lower equipment cavity 101 and an upper refrigeration cavity 102.

[0036] The semiconductor cooling system includes a temperature control component 3 and a heat sink 4. The temperature control component 3 is located in the device cavity 101 of the housing 1 and its cold end ceramic plate 301 is embedded and fixed in the partition plate 2. The heat sink 4 is fixed on the side wall of the housing 1 corresponding to its device cavity 101 and is connected to the device cavity 101 of the housing 1.

[0037] Specifically, the cold end ceramic plate 301 of the temperature control component 3 is flush with the upper side of the partition plate 2, or the cold end ceramic plate 301 of the temperature control component 3 is higher than the upper side of the partition plate 2; the heat sink 4 is fixed on the bottom surface of the casing 1, for example, the heat sink 4 is a fan.

[0038] The temperature control component 3, as the core component of the semiconductor refrigeration system, includes a cold-end ceramic plate 301, a first guide plate 302, a thermocouple pair 303, a second guide plate 304, a hot-end ceramic plate 305, and a heat dissipation fin 306 connected in sequence. The cold-end ceramic plate 301 is the cold source, and the hot-end ceramic plate 305 is the heat source. The hot-end ceramic plate 305 releases heat through the heat dissipation fin 306 and is discharged through the radiator 4 to the equipment cavity 101 of the housing 1.

[0039] The storage disk 9 is adapted to the cooling cavity 102 of the housing 1, that is, the storage disk 9 can be embedded in the cooling cavity 102 of the housing 1. The storage disk 9 is provided with a partition plate 10, which evenly divides the inner cavity of the storage disk 9 into several cooling zones 901.

[0040] The number of carrier disks 11 is the same as the number of cooling zones 901 in the storage disk 9, and the carrier disks 11 are compatible with the cooling zones 901, that is, the carrier disks 11 can be embedded in the cooling zones 901 of the storage disk 9.

[0041] According to the above design, the storage disk 9 is embedded in the cooling cavity 102 of the housing 1, and the carrier disk 11 is embedded in the cooling zone 901 of the storage disk 9. The storage disk 9 is cooled first by the storage base, and then the carrier disk 11 is cooled by the storage disk 9, so that the gauze block carrying the hair follicle unit in the carrier disk 11 is kept at a low temperature for continuous use in hair transplantation surgery.

[0042] In the above technical solution, to achieve real-time temperature control and display, a control box 5 is also included. The control box 5 is fixed on the casing 1, and a control display screen 6 is provided on the control box 5. A power supply 7 is provided inside the control box 5. The temperature control component 3, the heat sink 4, and the power supply 7 are all electrically connected to the control display screen 6. That is to say, the control display screen 6 on the control box 5 provides temperature control and display functions, and the power supply 7 inside the control box 5 supplies power to the temperature control component 3, the heat sink 4, and the control display screen 6.

[0043] In this embodiment, for example, the housing 1 and the partition plate 2 are both made of plastic material, which is conducive to manufacturing; the storage disk 9 and the carrier disk 11 are both made of stainless steel material, which takes into account both temperature conduction and postoperative high-temperature sterilization.

[0044] Specifically, the support plate 11 has a first connecting block 12 fixedly mounted at its bottom, and a first magnetic block 13 embedded in the lower side of the first connecting block 12. The support plate 11 serves as a device for supporting the separated hair follicle units and is used in conjunction with the support ring 15 during the surgical procedure.

[0045] More specifically, the top of the ring holder 15 is provided with a second connecting block 16, and a second magnetic block 17 is embedded in the upper side of the second connecting block 16. The second magnetic block 17 can attract the first magnetic block 13.

[0046] The procedure for hair transplantation based on the support plate 11 and the support ring 15 is as follows:

[0047] Use gauze (containing low-temperature sterile saline) to carry the separated hair follicle units, place them in the carrier tray 11, and place the carrier tray 11 in the cooling zone 901 of the storage tray 9 for low-temperature storage for later use.

[0048] After the medical staff put on the support ring holder 15, they took out a support plate 11 and connected the support plate 11 to the support ring holder 15 (the second magnetic block 17 and the first magnetic block 13 are attracted to each other), and then the transplantation began;

[0049] After the hair follicle units in a carrier plate 11 have been transplanted, the carrier plate 11 is removed and replaced with a gauze pad (with the hair follicle units placed in it beforehand), and the transplantation continues until the transplantation surgery is completed.

[0050] It should be noted that as the carrier disk 11 is continuously used, new carrier disks 11 (including newly separated hair follicle units) are also continuously placed in the cooling zone 901 of the storage disk 9.

[0051] Please see Figure 2 As shown, in a preferred embodiment, each storage disk 9 or partition plate 10 corresponding to each cooling zone 901 is provided with a serial number label 14. The serial number label 14 is used to mark different cooling zones 901 in sequence, so that the separated hair follicle units can be stored in sequence, and the low-temperature preserved hair follicle units can be taken out in sequence.

[0052] Please see Figure 1 As shown, in a preferred embodiment, the bottom of the housing 1 is provided with a support base 8, which is a rubber part. After adding the support base 8, the stability of the low-temperature storage device is better when it is placed on the workbench.

[0053] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
