Based on the above, the utility model provides the cupping and bloodletting device which integrates vacuumizing, needling and bloodletting, thereby effectively reducing labor intensity and operation difficulty and improving use convenience.

As shown in fig. 1 and 2, the present utility model provides a cupping and bloodletting apparatus including a housing 1, a bloodletting canister 2, an aspiration pump 3 and a bloodletting mechanism 4. The blood letting canister 2 is detachably connected to the housing 1. The air pump 3 is fixedly arranged in the shell 1 and is communicated with the bleeding tank 2. The bloodletting mechanism 4 includes a driving component 41 and a bloodletting needle 42, the driving component 41 is fixedly installed in the casing 1, the bloodletting needle 42 is detachably installed in the driving component 41, the driving component 41 can reciprocate along a first direction and drive the bloodletting needle 42 to move.

In the present embodiment, the blood letting needle 42 is provided as a disposable sterile three-edged needle. Of course, in other embodiments, the lancet 42 may be configured in other manners according to practical application requirements, which is not limited herein.

Wherein the above and below first directions refer to the X-axis as shown in fig. 2 in the axial bi-directional direction thereof, i.e., the axial direction of the first driving lever 411.

Specifically, when the device is used, the bloodletting canister 2 is first faced to the acupoint or abscess to cover the acupoint or abscess into the bloodletting canister 2. The switch of the air pump 3 is opened, and the air pump 3 can pump air from the blood discharge tank 2, and the atmospheric pressure in the blood discharge tank 2 is smaller than the atmospheric pressure outside the blood discharge tank 2 so as to generate negative pressure in the blood discharge tank 2. The cupping and bloodletting device further comprises a power supply fixedly arranged in the shell 1, and the air pump 3 is electrically connected to the power supply. As a result of the negative pressure generated in the blood vessel 2, a bulge is formed at the acupoint or abscess. The medical personnel press the drive assembly 41 such that the drive assembly 41 moves in a first direction toward the lancet 2, and the drive assembly 41 moves the lancet 42 in the first direction toward the lancet 2 until the lancet 42 pierces the protuberance. The medical staff releases the pressing of the driving component 41, the driving component 41 moves back to the blood drawing tank 2 along the first direction, and the driving component 41 drives the blood drawing needle 42 to move back to the blood drawing tank 2 along the first direction until the blood drawing needle 42 is pulled out from the bulge. Under the action of negative pressure, blood flows out from the punctured place. Then the shell 1 and the blood-discharging pot 2 are separated, and the next acupoint or abscess can be subjected to cupping and blood discharging.

The cupping and bloodletting device provided by the utility model can generate negative pressure in the bloodletting tank 2 under the action of the air pump 3, and form bulges at acupuncture points or abscess; under the action of the driving component 41 and the bleeding needle 42, the skin can be punctured at the bulge to perform bleeding, and then the cupping and bleeding can be completed. In the use process, the device does not need to be frequently replaced, which is beneficial to simplifying the operation flow, reducing the operation difficulty and greatly improving the use convenience. In addition, the bloodletting tank 2 is detachably connected with the shell 1, so that after bloodletting at one acupoint or abscess is completed, the next acupoint or abscess can be bloodletting, and the treatment efficiency can be improved.

In one embodiment of the present utility model, referring to fig. 1 to 3, the housing 1 has a first limiting table 11. The driving assembly 41 includes a first driving rod 411, a second limiting table 412, a first elastic structure 413 and a magnetic structure 414, where the first driving rod 411 is fixedly installed in the housing 1 and penetrates through the first limiting table 11, and at least partially extends to the outside of the housing 1, the second limiting table 412 is formed on the outer peripheral side of the first driving rod 411, the first elastic structure 413 is sleeved on the first driving rod 411 and is abutted between the first limiting table 11 and the second limiting table 412, and the magnetic structure 414 is arranged on the blood letting can 2 and is used for driving the blood letting needle 42 to move towards the first driving rod 411 along the first direction.

Specifically, upon pressing the drive assembly 41, an external force acts on the first drive rod 411 in a first direction, such that the first drive rod 411 moves in the first direction toward the blood letting canister 2 until the blood letting needle 42 pierces the bulge. The first limiting table 11 is also moved toward the blood letting canister 2 in the first direction, that is, toward the second limiting table 412 by the first driving lever 411, and at this time, the distance between the first limiting table 11 and the second limiting table 412 is shortened. Since the first elastic structure 413 is abutted between the first limiting table 11 and the second limiting table 412, the first elastic structure 413 is gradually compressed under the action of the first limiting table 11 and the second limiting table 412, and simultaneously stores elastic potential energy. When the driving assembly 41 is pressed, the elastic potential energy stored by the first elastic structure 413 acts on the first limiting table 11, so that the first limiting table 11 moves back to the blood letting canister 2 along the first direction, and the first driving rod 411 also moves back to the blood letting canister 2 along the first direction under the action of the first limiting table 11.

So configured, the first driving lever 411 can perform a reciprocating motion in the first direction under the interaction of the first stopper 11, the first driving lever 411, the second stopper 412, and the first elastic structure 413. And, after the first driving rod 411 moves towards the blood letting canister 2 along the first direction, under the action of the first elastic structure 413, the first driving rod 411 can be driven to move away from the blood letting canister 2 along the first direction, and the first driving rod 411 does not need to be manually restored to the initial state, thereby being beneficial to improving the convenience of use. The first driving rod 411 is arranged on the first limiting table 11 in a penetrating manner, and in the moving process, the first limiting table 11 can guide the first driving rod 411, so that the first driving rod 411 is ensured to move along the first direction, and the first driving rod 411 is prevented from being deviated from the first direction to cause the puncture of the lancet 42. In addition, under the action of the first elastic structure 413, the first elastic structure 413 can apply a reaction force to the medical staff through the second limiting table 412 and the first driving rod 411, so that the medical staff can be prevented from excessively penetrating the blood letting needle 42 too deeply, the comfort of a patient can be improved, and the occurrence of medical accidents can be prevented.

Alternatively, as shown in fig. 8, the magnetic structure 414 includes a first magnet 4141 and a second magnet 4142, where the first magnet 4141 is fixedly mounted on the tank 21, and the second magnet 4142 is magnetically attracted to a side of the first magnet 4141 facing away from the first driving rod 411.

Specifically, when the first driving lever 411 is pressed to move in the first direction toward the blood letting tank 2, the first driving lever 411 drives the blood letting needle 42 to move in the first direction toward the blood letting tank 2. The second magnet 4142 is moved away from the first magnet 4141 in the first direction by the ejector pin 42. Here, the first magnet 4141 is provided with a plurality of first through holes (not shown in the figure), the plurality of first through holes are arranged in one-to-one correspondence with the blood letting needle 42, the second magnet 4142 is provided with a plurality of second through holes (not shown in the figure), and the plurality of second through holes are arranged in one-to-one correspondence with the blood letting needle 42. Wherein the diameter of the first through hole is larger than the diameter of the second through hole. It should be noted that, as shown in fig. 9, the lancet 42 includes a first body 421 and a second body 422, the first body 421 is disposed through the first through hole, the second body 422 is disposed through the second through hole, the diameter of the first body 421 is larger than the diameter of the second body 422, and the diameter of the first body 421 is larger than the diameter of the second through hole. Therefore, when the lancet 42 moves toward the blood vessel 2 along the first direction, the first body 421 can drive the second magnet 4142 to move away from the first magnet 4141 along the first direction due to the fact that the diameter of the first body 421 is larger than that of the second through hole. When the first driving rod 411 moves back to the blood letting canister 2 along the first direction, the first driving rod 411 releases the limit of the blood letting needle 42, and the second magnet 4142 is driven by the magnetic attraction of the first magnet 4141 to move toward the first driving rod 411 along the first direction until the second magnet 4142 contacts with the first magnet 4141, so that the blood letting needle 42 stops moving because the diameter of the first main body 421 is larger than the diameter of the second through hole.

Wherein the lancet 42 passes through the sealing plug 23, the first magnet 4141 and the second magnet 4142 in sequence before the device is used. After the device is used, the lancet 42 is inserted through the sealing plug 23, the first magnet 4141 and the second magnet 4142, and is not separated with the separation of the housing 1 and the blood letting canister 2. During the exsanguination process, the exsanguination needle 42 is spaced from the bulge by the second magnet 4142. After the completion of the exsanguination, the exsanguination needle 42 can be withdrawn from the sealing plug 23, the first magnet 4141 and the second magnet 4142, and the exsanguination needle 42 can be disposed of as medical waste. It is also necessary to recover the bloodletting canister 2 and sterilize the bloodletting canister 2 for the next use. After the sterilization of the blood vessel 2, a new blood drawing needle 42 is inserted in advance into the sealing plug 23, the first magnet 4141 and the second magnet 4142, and stored in a sterile environment (for example, a sterilizing cabinet). When reuse is required, the product is taken out of the sterile environment (e.g., a sterilizer) directly for use. In addition, after cupping is completed at one or more positions, the cavity in the housing 1 is sterilized directly from the opening of the housing 1 where the fastening groove 13 is provided.

So configured, under the action of the first driving lever 411, the lancet 42 can be driven to move toward the bulge in the first direction. Under the action of the lancet 42, the first magnet 4141 and the second magnet 4142 can be separated, and the first driving lever 411 can be attached again after releasing the limit of the lancet 42. In this way, after the lancet 42 pierces the bulge, the lancet 42 can be pulled out from the bulge under the action of the second magnet 4142, and the manual pulling out of the lancet 42 is not required, which contributes to the improvement of the convenience of use. After the second magnet 4142 moves in the first direction toward the first magnet 4141, the movement of the lancet 42 is stopped, so that the portion of the lancet 42 that pierces the human body can be prevented from entering the housing 1, and blood can be prevented from entering the housing 1, thereby avoiding cross infection. In addition, after the completion of the bleeding, the bleeding needle 42 can be directly drawn out from the sealing plug 23, the first magnet 4141 and the second magnet 4142, facilitating replacement of the bleeding needle 42.

Optionally, the first elastic structure 413 is provided as a spring or a leaf spring.

In one embodiment of the present utility model, referring to fig. 1 to 3, the bloodletting mechanism 4 further includes a locking assembly 43, wherein the locking assembly 43 is disposed in the housing 1 and configured to reciprocate along the second direction to adjust the position of the first driving rod 411 in the first direction.

The second direction above and below refers to a bidirectional direction along the axial direction thereof, specifically the Y-axis shown in fig. 2, when it is described herein.

Specifically, when the position of the first driving rod 411 in the first direction needs to be adjusted, the locking assembly 43 is first controlled to move along the second direction away from the first driving rod 411 to release the limit on the first driving rod 411, and at this time, the first driving rod 411 can move along the first direction. According to the actual application situation, the first driving rod 411 is controlled to move to the target position, and after the first driving rod 411 moves to the target position, the locking assembly 43 is controlled to move towards the first driving rod 411 along the second direction until the locking assembly 43 is limited on the first driving rod 411, and at this time, the first driving rod 411 cannot move along the first direction.

So configured, as compared to the related art in which the locking assembly 43 is not provided, the heights of the protuberances of different patients are different due to the different physique of the patients, and when the first driving lever 411 is controlled to drive the lancet 42 to pierce the protuberances, the medical staff concentrates on observing the position of the lancet 42, that is, the position of the first driving lever 411. In the practical application process, can be spacing to first actuating lever 411 under locking component 43's effect, after spacing to first actuating lever 411, the medical staff of being convenient for carefully observe the position of first actuating lever 411 and bloodletting needle 42 prevents that medical staff from appearing first actuating lever 411 and follow the condition that first direction was moved dorsad bloodletting jar 2 in the observation in-process to according to actual conditions regulation, help improving the convenience of use.

Specifically, when the first driving rod 411 needs to be limited, the driving member 431 is controlled to move toward the first driving rod 411 along the second direction, and the second limiting teeth 433 are also moved toward the first driving rod 411 along the second direction under the action of the driving member 431 until the second limiting teeth 433 are abutted against the first driving rod 411 and limited by any one of the first limiting teeth 432. When the first driving rod 411 is required to be limited, the driving member 431 is controlled to move back to the first driving rod 411 along the second direction, the second limiting teeth 433 also move back to the first driving rod 411 along the second direction under the action of the driving member 431 until the second limiting teeth 433 and the first limiting teeth 432 are completely separated, and the first driving rod 411 can move back to the blood letting tank 2 along the first direction.

So configured, the second spacing tooth 433 is capable of reciprocating in the second direction under the influence of the driving member 431. After the second spacing tooth 433 moves toward the first driving rod 411 in the second direction, the second spacing tooth 433 can form a spacing with the first spacing tooth 432, so that the first driving rod 411 can be spacing. After the second spacing tooth 433 moves back to the moving driving rod in the second direction, the second spacing tooth 433 and the first spacing tooth 432 are released from spacing, and the first driving rod 411 can move in the first direction.

Alternatively, the first and second spacing teeth 432 and 433 are each provided with the second guide surface 434, or any one of the first and second spacing teeth 432 and 433 is provided with the second guide surface 434.

Specifically, when the first driving lever 411 moves toward the blood vessel 2 in the first direction, the plurality of first limiting teeth 432 are also moved toward the blood vessel 2 in the first direction by the first driving lever 411. The second limiting teeth 433 move away from the first driving rod 411 along the second direction under the action of the first limiting teeth 432, and the second limiting teeth 433 simultaneously drive the driving block 4311 to move away from the first driving rod 411 along the second direction. When the driving block 4311 moves along the second direction away from the first driving rod 411, the second elastic structure 4313 is compressed and stores elastic potential energy under the action of the driving block 4311 and the third limiting table 12. Until the second spacing tooth 433 and the first spacing tooth 432 are separated, the second elastic structure 4313 releases elastic potential energy, and drives the driving block 4311 to move toward the first driving rod 411 along the second direction, so that the above steps are repeated.
