Description

Technical Field

[0001] The utility model belongs to the technical field of syringes, and specifically relates to a syringe auxiliary pushing device. Background Art

[0002] At present, in minimally invasive medical aesthetics or other surgeries, it is necessary to use a beauty syringe to inject related substances into the skin tissue of users. In order to achieve good injection effects.

[0003] After retrieval, the document with the publication number (CN202211370678.X) discloses a disposable medical aesthetics depth-adjustable syringe, including a housing. An induction head is slidably inserted at the left end of the housing. A needle control mechanism is movably connected to the inner wall of the right cavity of the housing. The needle control mechanism includes a needle. A groove plate is fixedly connected to the surface of the needle. A liquid guide tube sleeved on the needle is fixedly connected to the inner wall of the housing. A needle control ring is rotatably connected to the inner wall of the housing. A guide block is fixedly connected to the upper wall of the inner cavity of the needle control ring. A resilient ratchet is rotatably connected to the front side of the inner wall of the needle control ring.

[0004] A microcurrent is applied to the initial induction head of the above device. After the relative position of the induction head and the needle is fixed, since the guide block is clamped to the groove plate, the housing can be used to drive the needle to penetrate into the skin to a reserved depth. After the induction head just touches the skin surface, according to the electrical properties of different substances, the electrical signal of the induction head changes. The energy storage ring automatically adjusts the circuit and connects the elastic tin strip. The elastic tin strip is instantly short-circuited and quickly heated to melt the pull film. The compressed elastic tin strip then rotates and resets, driving the needle control ring to move the guide block out and clamping the resilient ratchet into the groove plate. By then, when the user drives the housing to displace toward the side of the needle, due to the resilient ratchet not being restricted from rotating counterclockwise, under the resistance of the needle and the human skin tissue, the housing is then misaligned with the needle. After the needle penetrates to the specified depth, it cannot move further.

[0005] In actual operation of the above device, some syringes will be sleeved with rubber sleeves and other related obstructive mechanisms outside the needle to mark the penetration depth. However, due to the elastic effect of the human skin surface and observation errors, there will also be problems of overpressure or non-contact with the skin for this obstructive mechanism. In addition, the operation errors of medical staff can easily lead to a deviation between the penetration depth of the needle and the actual required depth, and due to the error in the final liquid medicine input depth.

The following embodiments are used to illustrate the present invention.

[0031] Please refer to Figures 1-5, A syringe auxiliary pushing device, comprising a base 1, on which a syringe body 2 is fixedly installed, and a suction pump is installed inside the syringe body 2; a syringe bracket 21, which is arranged on the syringe body 2, and the syringe bracket 21 is connected to the suction pump through a hose. When the syringe bracket 21 is in contact with the injection skin, the suction pump sucks out the air in the syringe bracket 21, so that the syringe bracket 21 and the syringe matching the syringe bracket 21 are closely attached to the skin, avoiding the problems of overpressure or non-contact with the skin; an adjustment component, which is arranged on the base 1 and is used to adjust the position of the syringe bracket 21. The adjustment component includes a support rod 3, an adjustment rod 4 and a movable rod 41. The support rod 3 is fixedly connected to the base 1. One end of the adjustment rod 4 is movably connected to the support rod 3. One end of the movable rod 41 is rotatably connected to the other end of the adjustment rod 4.

A first spring is sleeved on the connecting rod, and the first spring is fixedly connected to the support rod 3. The other end of the connecting rod abuts against the support rod 3. The adjustment component further includes a mounting seat 32, an abutting block 33 and a movable block 42. The mounting seat 32 is fixedly connected to the bottom end of the support rod 3.

The damping rotating shafts are used to interfere with the movement of the lifting block 31 and the adjustment rod 4, the movable rod 41 and the adjustment rod 4, and the movable block 42 and the movable rod 41. When the mounting seat 32 is engaged with the installation position and the abutting block 33 is rotated, the abutting block 33 rises and falls in the mounting seat 32 and fits with the installation position through the rising and falling of the abutting block 33, so as to fix the mounting seat 32 and the installation position. Manually move 34 to an angle perpendicular to the side wall of the lifting block 31. At this time, 34 lifts the connecting rod. Manually adjust the lifting block 31 to a suitable working position on the support rod 3. At this time, move 34 to an angle parallel to the side wall of the lifting block 31. The lifting block 31 pushes the connecting rod inward and abuts against the support rod 3. The force generated by the deformation of the first spring makes the connecting rod always fit with the support rod 3, so as to fix the position of the lifting block 31. Manually adjust the adjustment rod 4, the movable rod 41 and the movable block 42, so as to drive the adjustment rod 4, the movable rod 41 and the movable block 42 to rotate, extend and contract, so as to change the position of the boosting main body 5, and interfere with the movement of the adjustment rod 4, the movable rod 41 and the movable block 42 through the damping rotating shaft, avoiding the movement of the adjustment rod 4, the movable rod 41 and the movable block 42 after the boosting main body 5 rotates to a suitable injection position, and avoiding the shaking of the syringe on the skin caused by the shaking of the human hand when holding the injection device, which may cause damage to the internal tissues of the human body;The metering component is arranged at one end of the movable rod 41 and is used for metering and injecting drugs.

[0032] It should be noted that the suction pump can suck out the air in the syringe holder 21. The above suction pump has a pump component housing and at least one secretion or fluid collection and storage container detachably connected to the pump component housing. The pump component housing has a pump component. The suction pump has been disclosed in the suction pump unit of the prior art (CN200780016286.0) and will not be elaborated here.

[0033] Among them, the metering component includes a boosting body 5. A ball rod is installed on one side of the boosting body 5. The ball rod is rotatably connected to the ball socket on the movable block 42. A damper is installed between the boosting body 5 and the movable block 42. A controller is installed on the boosting body 5. The metering component also includes a pushing block 51, a telescopic motor 52 and a sliding sleeve 53. The telescopic motor 52 is fixedly connected to the inner wall of the boosting body 5. The sliding sleeve 53 is threadedly connected to the output shaft of the telescopic motor 52. The pushing block 51 is fixedly connected to the sliding sleeve 53. A groove is formed on the boosting body 5. The pushing block 51 is slidably connected to the groove on the boosting body 5. The controller is electrically connected to the telescopic motor 52. The metering component also includes a limiting block 6 and a support rod 61. The support rod 61 is slidably connected to the inner wall of the boosting body 5. The limiting block 6 is fixedly connected to the support rod 61. A second spring is sleeved on the support rod 61. One end of the second spring is fixedly connected to the support rod 61, and the other end of the second spring is fixedly connected to the inner wall of the boosting body 5. Manually pull up the limiting block 6, and the limiting block 6 drives the support rod 61 to move upward. Place the syringe holder 21 on the boosting body 5. When the support rod 61 moves upward, it squeezes the second spring and deforms. At this time, let go, and the force generated by the deformation of the second spring drives the support rod 61 and the limiting block 6 downward. The syringe holder 21 is fixed by closely contacting the surface of the syringe holder 21 through the limiting block 6. The output shaft of the telescopic motor 52 drives the sliding sleeve 53 to rotate through the thread, and the sliding sleeve 53 is limited by the pushing block 51, so that the sliding sleeve 53 and the pushing block 51 perform linear motion. The rotation of the telescopic motor 52 is controlled by the controller, so as to achieve precise metering injection, avoid the injection volume deviation caused by the inability of manpower to finely control during manual injection, thereby affecting the medical effect. Excessive injection may have a negative impact on the human body, and too little injection may result in poor medical effects.

[0034] Working principle: Engage the mounting base 32 with the mounting position, rotate the abutting block 33, and the abutting block 33 moves up and down within the mounting base 32. It fits with the mounting position through the up and down movement of the abutting block 33, thereby fixing the mounting base 32 to the mounting position. Manually move 34 to an angle perpendicular to the side wall of the lifting block 31. At this time, 34 lifts the connecting rod. Manually adjust the lifting block 31 to a suitable working position on the support rod 3. Then move 34 to an angle parallel to the side wall of the lifting block 31. The lifting block 31 pushes the connecting rod inward and abuts against the support rod 3. The force generated by the deformation of the first spring makes the connecting rod always fit the support rod 3, thereby fixing the position of the lifting block 31. When injection is required, manually place the syringe matching the syringe holder 21 into the syringe holder 21. At this time, manually pull up the limit block 6, and the limit block 6 drives the support rod 61 to move upward. Place the syringe holder 21 on the boosting main body 5. When the support rod 61 moves upward, it squeezes the second spring and deforms. Then release the hand. The second spring drives the support rod 61 and the limit block 6 downward through the force generated by the deformation. The limit block 6 tightly contacts the surface of the syringe holder 21 to fix the syringe holder 21. At this time, manually adjust the adjusting rod 4, the movable rod 41, and the movable block 42, so as to drive the adjusting rod 4, the movable rod 41, and the movable block 42 to rotate, extend, and contract, thereby changing the position of the boosting main body 5. The damping rotating shaft interferes with the movement of the adjusting rod 4, the movable rod 41, and the movable block 42 to prevent the adjusting rod 4, the movable rod 41, and the movable block 42 from moving after the boosting main body 5 rotates to the appropriate injection position, and to prevent the syringe from shaking on the skin due to the shaking of the human hand when holding the injection device, which may cause damage to the human internal tissues. When the syringe holder 21 fits with the injection skin, the suction pump sucks out the air in the syringe holder 21, so that the syringe holder 21 and the syringe matching the syringe holder 21 fit tightly with the skin, avoiding the problems of overpressure or non-contact with the skin. At this time, the output shaft of the telescopic motor 52 drives the sliding sleeve 53 to rotate through the thread, and limits the sliding sleeve 53 through the pushing block 51, so that the sliding sleeve 53 and the pushing block 51 perform linear motion. The controller controls the rotation of the telescopic motor 52 to achieve precise quantitative injection, avoiding the deviation of the injection volume caused by the inability of manual injection to be finely controlled, which may affect the medical effect. Excessive injection may have a negative impact on the human body, and too little injection may result in poor medical effects.

Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model.
