Description

Technical Field

[0001] The utility model relates to the technical field of water light needles, and in particular to a water light needle structure. Background Art

[0002] At present, the commonly used hyaluronic acid injections on the market use negative pressure to allow the needle to inject high-end injection products such as hyaluronic acid, collagen, botulinum toxin, PRP autologous cells, etc. that are lost by the human body due to aging into the dermis of the skin.

[0003] In the Chinese utility model patent with the authorization announcement number CN207024401U, a water light needle is disclosed, which uses a suction cup to cooperate with a vacuum device. The vacuum device turns the suction cup into a negative pressure vacuum area through a vacuum pipe, so that the skin and the suction cup are firmly attached, and the suction cup continuously vacuums the skin, and there is no longer a safety concern after the negative pressure function fails, and in a reliable vacuum environment, the pain of the patient during injection is alleviated; and by sliding the pull rod in the through hole, the vacuum degree in the suction cup can be increased, the negative pressure can be increased, and the vacuum degree in the suction cup can be reduced by connecting the airway to the atmosphere; although the above patent can adjust the vacuum degree in the suction cup, whether it is necessary to reduce or increase the vacuum degree in the suction cup, it is necessary to first pull the pull rod through the pull ring, which will increase the vacuum degree in the suction cup. The vacuum degree can only be reduced after the pull rod is continuously pulled to connect the airway to the atmosphere. In the case where the vacuum degree in the suction cup itself is very large, the method of increasing the vacuum degree first and then reducing it will undoubtedly cause certain discomfort to the patient and aggravate the pain, and it is also possible to cause bleeding or bruising at the acupuncture site, which will cause a very bad user experience for the patient.

[0025] The vacuum degree of the negative pressure cover 5 is adjusted according to the specific usage situation. The operating member is moved toward the outside of the support member to increase the vacuum degree in the negative pressure cover 5. The rotating member is kept stationary and the sealing member is opened to connect the second channel with the first channel and the negative pressure cover 5, thereby reducing the vacuum degree in the negative pressure cover 5. The operation is simple and convenient, and the vacuum degree in the negative pressure cover 5 can be quickly adjusted according to the actual situation, thereby reducing the pain of the patient during acupuncture treatment, and effectively avoiding bleeding and bruising caused by excessive negative pressure during acupuncture, thereby improving the user experience and ensuring the treatment effect.

[0026] like Figure 1 as well as Figure 5 As shown, according to another embodiment of the utility model, the aqua-light needle structure is further optimized with respect to the supporting member, rotating member and sealing member included therein, the supporting member includes an internal threaded tube 7 fixedly installed through and between the inner and outer sides of the negative pressure cover 5, the first channel is the inner hole of the internal threaded tube 7, and the rotating member is threadedly connected to the inner hole of the internal threaded tube 7.

[0027] The rotating part includes an adjusting bolt 8 threadably connected to the internal threaded tube 7, and the second channel is a pressure relief channel 81 coaxially opened therein, and the sealing member is plug-in-connected to the pressure relief channel 81; by rotating the adjusting bolt 8 to rotate it toward the outside of the internal threaded tube 7, the vacuum degree in the negative pressure mask 5 can be slowly increased, and the adjustment speed will not be very fast, which can enable the patient to better adapt to the adjustment process.

[0028] The sealing member comprises a sealing plug 82 which is pluggable and connected to the pressure relief channel 81. The sealing plug 82 is rotatably connected to the adjusting bolt 8 via a connecting strip 83.

Preferably, the sealing plug 82, the sealing bowl 84 and the connecting strip 83 are all made of rubber material, so that the connecting strip 83 and the adjusting bolt 8 can be flexibly connected.

[0029] like Figure 1-4 As shown, according to another embodiment of the utility model, the aqua-light needle structure, preferably, the syringe comprises a barrel 1 and a barrel tube 2 coaxially rotatably connected, the connecting head 11 is arranged at the bottom of the barrel 1, the negative pressure cover 5 is coaxially fixedly installed on the end of the barrel tube 2 away from the barrel 1, and a telescopic mechanism is provided between the barrel tube 2 and the needle seat 4 to adjust the length of the needle body 6 extending out of the negative pressure cover 5; preferably, the barrel 1 and the barrel tube 2 are rotatably connected by a clamping piece; an annular groove is opened on the end face of the barrel mouth of the barrel 1 along its circumference, and a clamping ring 21 is fixedly installed on one end face of the barrel tube 2, the clamping ring 21 is rotatably connected to the annular groove, and the cross-sections of the clamping ring 21 and the annular groove are both T-shaped; the rotation stability of the barrel 1 and the barrel tube 2 can be better guaranteed.

[0030] Preferably, an annular groove 41 is coaxially opened on the upper part of the needle seat 4, and a plurality of needle bodies 6 are located in the annular groove 41. The telescopic mechanism includes a connecting tube 3, and the connecting tube 3 is fixedly connected to the inner wall of the barrel 1 through an outer edge 31 fixedly sleeved at one end thereof. The outer wall of the needle seat 4, the inner wall of the annular groove 41 away from the plurality of needle bodies 6, the outer wall of the connecting tube 3 and the inner wall of the barrel 2 are all provided with threads. The outer wall of the needle seat 4 is threadedly connected with the inner wall of the barrel 2, and the connecting tube 3 is rotatably arranged in the annular groove 41, and the outer wall of the connecting tube 3 is threadedly connected with the inner wall of the annular groove 41 away from the plurality of needle bodies 6; when in use, the barrel 1 is held in one hand and the barrel 2 is held in the other hand, and then the barrel 1 is rotated and the barrel 2 is kept stationary. Since the outer wall of the needle seat 4 is threadedly connected with the inner wall of the barrel 2, and the outer wall of the connecting tube 3 is threadedly connected with the inner wall of the annular groove 41 away from the plurality of needle bodies 6, the needle seat 4 can drive the plurality of needle bodies 6 to move toward the outside of the negative pressure cover 5 through threaded transmission during the rotation of the barrel 1, thereby changing the length of the needle bodies 6 inserted into the skin.

[0031] The use principle of the utility model is as follows: when the utility model is used, according to the specific circumstances during use, when the vacuum degree in the negative pressure cover 5 is too high, the sealing plug 82 is pulled out to make the pressure relief channel 81 communicate with the inside and outside of the negative pressure cover 5 to reduce the vacuum degree in the negative pressure cover 5; when the vacuum degree in the negative pressure cover 5 is low, the sealing plug 82 is ensured to be well sealed, and at the same time, the adjusting bolt 8 is rotated to move it toward the outside of the internal threaded tube 7 to slowly increase the vacuum degree in the negative pressure cover 5; if it is necessary to adjust the length of the needle body 6 piercing the skin, the barrel 1 is held in one hand and the barrel tube 2 is held in the other hand, and then the barrel 1 is rotated and the barrel tube 2 is kept stationary. During the rotation of the barrel 1, the needle seat 4 can drive a number of needle bodies 6 to move toward the outside of the negative pressure cover 5 through threaded transmission.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
