Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an analgesic device. Background Technology

[0002] Pain management is a crucial field in modern medicine. Pain not only affects patients' quality of life but can also lead to a range of physiological and psychological problems. Traditional pain relief methods include drug therapy, physical therapy, and psychotherapy, among which analgesic devices are widely used as a novel pain management tool in addition to drug therapy.

[0003] Existing analgesics consist of a syringe and a needle. The needle is inserted into the body by holding the syringe, and then the drug inside the syringe is injected into the body by pressing down with the thumb.

[0004] However, during the injection process, the syringe is prone to shaking, which can puncture the subcutaneous tissue and increase the pain at the injection site for the patient. Utility Model Content

[0005] This application provides an analgesic device to reduce syringe vibration during drug injection.

[0006] This embodiment provides an analgesic device, comprising:

[0007] Injection mechanism, used to hold the syringe in place;

[0008] A support mechanism, connected to the injection mechanism, is used to support the injection mechanism;

[0009] A buffer mechanism is provided on the support mechanism, which is used to apply a counterforce when the support mechanism shakes, so as to reduce the shaking of the syringe.

[0010] In this embodiment of the application, the support mechanism includes a support frame, and the buffer mechanism includes a first connecting block, a buffer plate, and two elastic components;

[0011] The first connecting block is connected at both ends to the support frame and the buffer plate, respectively;

[0012] The buffer plate is connected to the support frame at both ends by two elastic components, which are used to reduce the relative sway between the buffer plate and the support plate.

[0013] In this embodiment of the application, the support frame is provided with a sliding groove, and the elastic component includes a second connecting block, a first sliding rod, a second sliding rod, and an elastic telescopic rod;

[0014] The second connecting block is disposed on the buffer plate;

[0015] One end of the first sliding rod is slidably connected to the slide groove, and the other end is hinged to the second connecting block;

[0016] The second sliding rod is slidably connected to the first sliding rod;

[0017] The two ends of the elastic telescopic rod are respectively hinged to the support frame and the second sliding rod. The elastic telescopic rod applies an elastic force to the first sliding rod through the second sliding rod to reduce the sliding distance of the first sliding rod in the groove when the buffer plate and the support frame shake relative to each other.

[0018] In this embodiment of the application, a fixing mechanism is also included, which includes two fixing blocks and two bandages;

[0019] The two fixing blocks are respectively disposed on opposite sides of the support frame. The two fixing blocks are connected to the two bandages in a one-to-one correspondence. The ends of the two bandages away from the corresponding two fixing blocks are connected by buckles.

[0020] In this embodiment, the injection mechanism includes a first rectangular groove plate, a second rectangular groove plate, and a limiting component;

[0021] The first rectangular groove plate and the second rectangular groove plate are slidably connected. The limiting component is disposed on the first rectangular groove plate and the second rectangular groove plate is disposed on the support frame. The first rectangular groove plate is used to accommodate the syringe and drive the syringe to move. The limiting component is used to fix the syringe in the first rectangular groove plate.

[0022] In this embodiment of the application, the limiting component includes a mounting base, a rotating rod, an L-shaped limiting block, and a locking part;

[0023] The mounting base is disposed on the first rectangular groove plate, the rotating rod is rotatably disposed on the mounting base, the L-shaped limiting block is disposed on the rotating rod, and the locking part is connected to the rotating rod. When the L-shaped limiting block rotates to the position of abutting against the syringe, the locking part fixes the rotating rod to lock the L-shaped limiting block in the abutting position.

[0024] In this embodiment of the application, the locking part includes a connecting rod, a locking block, a first mounting post, a second mounting post, and a locking spring;

[0025] One end of the connecting rod is connected to the rotating rod, and the other end is connected to the first mounting post. The second mounting post is disposed on the mounting base.

[0026] The two ends of the locking spring are respectively hinged to the first mounting post and the second mounting post, and the locking block is disposed on the mounting base;

[0027] When the L-shaped limiting block abuts against the syringe, the connecting rod abuts against the locking block, and the locking spring applies an elastic force to the connecting rod through the first mounting post to fix the L-shaped limiting block.

[0028] In this embodiment of the application, a striking mechanism is also included, which includes an electric telescopic rod and a striking frame;

[0029] One end of the electric telescopic rod is connected to the second rectangular groove plate, and the other end is connected to the striking frame. The electric telescopic rod is used to control the striking frame to strike the skin.

[0030] In this embodiment, the striking mechanism further includes a proximity switch, which is disposed on the electric telescopic rod. The proximity switch controls the opening and closing of the electric telescopic rod by sensing the distance the first rectangular slot plate slides within the second rectangular slot plate.

[0031] In this embodiment of the application, the buffer plate is an arc-shaped plate.

[0032] This application provides an analgesic device including an injection mechanism for fixing a syringe; a support mechanism connected to the injection mechanism for supporting the injection mechanism; and a buffer mechanism disposed on the support mechanism, which applies a counterforce when the support mechanism shakes, thereby reducing the shaking of the syringe. The buffer mechanism reduces syringe shaking during drug injection, preventing excessive syringe deviation that could cause puncture wounds to the subcutaneous tissue around the needle hole, thus improving the stability of the syringe during injection.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0051] Patient-controlled analgesia is a pain management technique in which medical staff pre-set the dosage of analgesic drugs based on the patient's pain level, nature, duration, and tolerance, and then entrust the patient with good self-awareness and control to "self-manage" the pain.

[0052] Patients usually need to use an analgesic device to administer medication. Existing analgesics include a syringe and an injection needle. The needle is inserted into the body by holding the syringe, and then the medication is injected into the body by pressing down with the thumb.

[0053] During the injection process, the syringe needs to be held and injected slowly for a long time. It is impossible to keep the injection needle inside the body for a long time, which will increase the pain at the injection site for the patient.

[0054] This embodiment provides an analgesic device that reduces syringe movement during injection by incorporating a buffer mechanism, thus avoiding pain caused by needle movement during injection. The following description, in conjunction with the accompanying drawings, further illustrates this application.

[0055] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an analgesic device provided in an embodiment of this application.

[0056] This application provides an analgesic device, including an injection mechanism 100 for fixing a syringe 10; a support mechanism 200 connected to the injection mechanism 100 for supporting the injection mechanism 100; and a buffer mechanism 300 disposed on the support mechanism 200, which applies a counterforce when the support mechanism 200 shakes to reduce the shaking of the syringe 10.

[0057] The buffer mechanism 300 reduces the shaking of the syringe 10 during drug injection, preventing excessive deviation of the syringe 10 from causing puncture wounds to the subcutaneous tissue around the needle hole, thereby improving the stability of the syringe 10 during injection.

[0058] The injection mechanism 100 and the buffer mechanism 300 are arranged opposite each other on the upper and lower sides of the support mechanism 200. When the buffer mechanism 300 is attached to the skin, the syringe 10 inside the injection mechanism 100 can be pushed to achieve injection. During the injection process, the buffer mechanism 300 can slow down the shaking of the syringe 10 to avoid the needle puncturing the subcutaneous tissue.

[0059] The support mechanism 200 has a mounting groove in the middle, and the injection mechanism 100 is installed in the mounting groove. The needle of the syringe 10 can pass through the support mechanism 200 through the mounting groove.

[0060] like Figure 2 As shown, Figure 2 for Figure 1 A schematic diagram of the structure in which the central support mechanism 200 and the buffer mechanism 300 cooperate.

[0061] In this embodiment, the support mechanism 200 includes a support frame 210, and the buffer mechanism 300 includes a first connecting block 310, a buffer plate 320, and two elastic components 330.

[0062] The first connecting block 310 is connected to the support frame 210 and the buffer plate 320 at both ends, respectively.

[0063] The two ends of the buffer plate 320 are connected to the support frame 210 through two elastic components 330. The elastic components 330 are used to reduce the relative sway between the buffer plate 320 and the support plate.

[0064] The first connecting block 310 is located at the bottom center of the support frame 210, the middle part of the buffer plate 320 is fixedly connected to the first connecting block 310, and the two elastic components 330 are symmetrically arranged on both sides of the first connecting block 310, so that the buffer plate 320 is subjected to more uniform force.

[0065] The length of the buffer plate 320 is equal to or greater than the length of the support frame 210, so that the buffer plate 320 can fully contact the skin and improve comfort.

[0066] When the syringe 10 shakes from side to side during injection, the elastic components 330 on both sides will apply a reverse force in the direction of shaking, thereby reducing the degree of shaking.

[0067] A clearance groove is provided in the middle of the buffer plate 320 so that the needle of the syringe 10 can pass through the clearance groove to contact the skin.

[0068] Combination Figure 2 and Figure 3 As shown, Figure 3 for Figure 2 A schematic diagram of the structure of the elastic component.

[0069] In this embodiment, the support frame 210 is provided with a sliding groove 211. The elastic component 330 includes a second connecting block 331, a first sliding rod 332, a second sliding rod 333, and an elastic telescopic rod 334. The second connecting block 331 is disposed on the buffer plate 320. One end of the first sliding rod 332 is slidably connected to the sliding groove 211, and the other end is hinged to the second connecting block 331. The second sliding rod 333 is slidably connected to the first sliding rod 332. Both ends of the elastic telescopic rod 334 are respectively hinged to the support frame 210 and the second sliding rod 333. The elastic telescopic rod 334 applies an elastic force to the first sliding rod 332 through the second sliding rod 333 to reduce the sliding distance of the first sliding rod 332 in the sliding groove 211 when the buffer plate 320 and the support frame 210 shake relative to each other.

[0070] For example, the two elastic components 330 have the same structure. Taking one of the elastic components 330 as an example, the elastic component 330 includes two second connecting blocks 331, two first sliding rods 332, a second connecting rod 135, two second connecting blocks 331 and a connecting rod.

[0071] The support frame 210 has two sliding grooves 211 at opposite ends on the same side, and two second connecting blocks 331 are provided on the corresponding buffer plate 320. The first ends of the two first sliding rods 332 are respectively hinged to the two second connecting blocks 331, and the second ends of the two first sliding rods 332 are respectively slidably connected to the two sliding grooves 211.

[0072] The two ends of the second connecting rod 135 are slidably connected to the two first sliding rods 332 respectively. Two parallel elastic telescopic rods 334 are hinged on the second connecting rod 135. The ends of the two elastic telescopic rods 334 away from the second connecting rod 135 are hinged to the hinge rod 335. The hinge rod 335 is fixed to the bottom of the support frame 210.

[0073] The elastic telescopic rod 334 includes a rod body 336 and a buffer spring 337. The rod body 336 includes a first sleeve rod and a second sleeve rod. The first sleeve rod is sleeved on the outside of the second sleeve rod. One end of the buffer spring 337 is connected to the bottom of the first sleeve rod, and the other end of the buffer spring 337 is connected to the middle of the second sleeve rod.

[0074] When the syringe 10 shakes, one end of the support frame 210 moves toward the buffer plate 320, and one end of the first sliding rod 332 rotates so that the other end slides along the slide groove 211. At this time, the telescopic rod applies an elastic force to the second sliding rod 333 to prevent the first sliding rod 332 from sliding, thereby blocking the movement of the support frame 210 and reducing the shaking of the syringe 10.

[0075] By setting two elastic telescopic rods 334 to increase the elastic force, the amplitude of the syringe 10 shaking is reduced. The forces on both sides of the support frame 210 are balanced by the cooperation of two second connecting blocks 331, two first sliding rods 332 and two sliding grooves 211.

[0076] like Figure 4 As shown, Figure 4 for Figure 1 A schematic diagram of the fixed mechanism.

[0077] In this embodiment of the application, a fixing mechanism 400 is also included, which includes two fixing blocks 410 and two bandages 420.

[0078] Two fixing blocks 410 are respectively set on opposite sides of the support frame 210. The two fixing blocks 410 are connected to the two bandages 420 one by one. The ends of the two bandages 420 away from the corresponding two fixing blocks 410 are connected by buckles.

[0079] The fixing block 410 is hinged to the support frame 210. One of the bandages 420 has a buckle opening at one end, and the other bandage 420 has a buckle block at one end. After the two bandages 420 are wrapped around the arm, they are connected together through their respective buckles openings and buckle blocks to fix the syringe 10 and other components to the arm.

[0080] like Figure 5 As shown, Figure 5 for Figure 1 A schematic diagram of the injection mechanism.

[0081] In this embodiment, the injection mechanism 100 includes a first rectangular groove plate 110, a second rectangular groove plate 120, and a limiting component 130.

[0082] The first rectangular groove plate 110 and the second rectangular groove plate 120 are slidably connected. The limiting component 130 is disposed on the first rectangular groove plate 110 and the second rectangular groove plate 120 is disposed on the support frame 210. The first rectangular groove plate 110 is used to accommodate the syringe 10 and drive the syringe 10 to move. The limiting component 130 is used to fix the syringe 10 in the first rectangular groove plate 110.

[0083] Wherein, the outer diameter of the first rectangular groove plate 110 is smaller than the inner diameter of the second rectangular groove plate 120, and the second rectangular groove plate 120 is sleeved on the outside of the first rectangular groove plate 110 to realize the sliding connection between the first rectangular groove plate 110 and the second rectangular groove plate 120.

[0084] The first rectangular slot plate 110 has an outer edge on its bottom outer side, and the second rectangular slot plate 120 has an inner edge on its top inner side. When the bottom of the first rectangular slot plate 110 moves to the top of the second rectangular slot plate 120, the outer edge and the inner edge abut against each other, thereby preventing the first rectangular slot plate 110 from detaching from the top of the second rectangular slot plate 120. The second rectangular slot plate 120 has an inwardly protruding protrusion inside, which is used to prevent the first rectangular slot plate 110 from detaching from the bottom of the second rectangular slot plate 120.

[0085] Two limiting components 130 are respectively disposed on two opposite side walls of the first rectangular groove plate 110. When the syringe 10 is inserted into the first rectangular groove plate 110, the handle on the syringe body will abut against the top of the first rectangular groove plate 110. At this time, the limiting component 130 abuts against the top of the handle to prevent the syringe 10 from detaching from the first rectangular groove plate 110.

[0086] Combination Figure 5-7 As shown, Figure 6 for Figure 5 A schematic diagram of the structure in which the first rectangular groove plate and the limiting component cooperate; Figure 7 for Figure 6 A schematic diagram of the middle limit component.

[0087] In this embodiment, the limiting component 130 includes a mounting base 131, a rotating rod 132, an L-shaped limiting block 133, and a locking part 134.

[0088] Mounting base 131 is mounted on the first rectangular slot plate 110. Rotating rod 132 is rotatably mounted on mounting base 131. L-shaped limiting block 133 is mounted on rotating rod 132. Locking part 134 is connected to rotating rod 132. When L-shaped limiting block 133 rotates to the position of abutting against syringe 10, locking part 134 fixes rotating rod 132 to lock L-shaped limiting block 133 in the abutting position.

[0089] For example, the two limiting components 130 have the same structure. Taking one of the limiting components 130 as an example, the limiting component 130 includes two mounting seats 131, a rotating rod 132, an L-shaped limiting block 133, and two locking parts 134. The two mounting seats 131 are arranged parallel to each other on the outer wall of the first rectangular slot plate 110. The two ends of the rotating rod 132 are respectively rotatably connected to the two mounting seats 131, and the two ends of the rotating rod 132 extend through the mounting seats 131 to the outside of the mounting seats 131. The L-shaped limiting block 133 is fixedly arranged in the middle of the rotating rod 132.

[0090] Two locking parts 134 are respectively provided on two mounting bases 131. The two ends of the rotating rod 132 are respectively connected to the two locking parts 134. When the L-shaped limiting block 133 rotates to the position of abutting against the syringe 10, the locking part 134 fixes the rotating rod 132 to fix the L-shaped limiting block 133, thereby fixing the syringe 10.

[0091] The end of the L-shaped limiting block 133 away from the rotating rod 132 abuts against the handle of the syringe 10.

[0092] Continue to combine Figure 5-7 As shown in the embodiment of this application, the locking part 134 includes a connecting rod 135, a locking block 136, a first mounting post 137, a second mounting post 138, and a locking spring 139.

[0093] One end of the connecting rod 135 is connected to the rotating rod 132, and the other end is connected to the first mounting post 137. The second mounting post 138 is mounted on the mounting base 131.

[0094] The two ends of the locking spring 139 are hinged to the first mounting post 137 and the second mounting post 138 respectively, and the locking block 136 is mounted on the mounting base 131.

[0095] When the L-shaped limiting block 133 abuts against the syringe 10, the connecting rod 135 abuts against the locking block 136, and the locking spring 139 applies an elastic force to the connecting rod 135 through the first mounting post 137 to fix the L-shaped limiting block 133.

[0096] The two locking parts 134 have identical structures; one of them will be used as an example. The bottom of the mounting base 131 extends to form an extension 140. A first mounting post 137 is located outside the connecting rod 135, a second mounting post 138 is located outside the extension 140, and a locking block 136 is located on the outer wall of the mounting base 131 near the end of the first rectangular groove plate 110. When the L-shaped limiting block 133 abuts against the syringe 10, the extension 140, the connecting rod 135, and the locking spring 139 form a triangle. The locking block 136 abuts against the connecting rod 135, and the locking spring 139 applies a downward force to the connecting rod 135, thereby preventing the L-shaped limiting block 133 from flipping outward.

[0097] For example, a locking block 136 is also provided on the outer wall of the mounting base 131 away from the first rectangular groove plate 110. When the L-shaped limiting block 133 disengages from the syringe 10, the L-shaped limiting block 133 flips outward, and the connecting rod 135 abuts against the locking block 136 away from the first rectangular groove plate 110 to prevent the L-shaped limiting block 133 from flipping outward further. At this time, the extension 140, the connecting rod 135 and the locking spring 139 form a new triangle that is symmetrical to the above-mentioned triangle.

[0098] like Figure 8 As shown, Figure 8 This is a schematic diagram of the percussion mechanism in an analgesic device provided in an embodiment of this application.

[0099] In this embodiment of the application, a striking mechanism 500 is also included, which includes an electric telescopic rod 510 and a striking frame 520.

[0100] One end of the electric telescopic rod 510 is connected to the second rectangular groove plate 120, and the other end is connected to the striking frame 520. The electric telescopic rod 510 is used to control the striking frame 520 to strike the skin.

[0101] The striking frame 520 has a rectangular frame structure. Four electric telescopic rods 510 are arranged around the bottom of the second rectangular groove plate 120. The four electric telescopic rods 510 are located at the four corners of the striking frame 520. The needle of the syringe 10 extends from the middle of the striking frame 520. The striking frame 520 can pass through the mounting groove and the clearance groove in sequence to contact the skin.

[0102] The electric telescopic pole 510 is equipped with a drive device and a power supply device. The drive device can be controlled to extend and retract the electric telescopic pole 510 by turning the power on and off. Since the structure of the electric telescopic pole 510 is existing technology, it will not be described in detail in this embodiment.

[0103] In this embodiment, the striking mechanism 500 further includes a proximity switch 530, which is disposed on the electric telescopic rod 510. The proximity switch 530 controls the opening and closing of the electric telescopic rod 510 by sensing the distance that the first rectangular slot plate 110 slides within the second rectangular slot plate 120.

[0104] The proximity switch 530 is located at the top of the electric telescopic rod 510, which is located on a protrusion inside the second rectangular slot plate 120. The top of the proximity switch 530 extends out of the protrusion or is parallel to the top of the protrusion. When the bottom of the first rectangular slot plate 110 approaches the proximity switch 530, the electric telescopic rod 510 is activated. When the bottom of the first rectangular slot plate 110 moves away from the proximity switch 530, the electric telescopic rod 510 is deactivated.

[0105] For example, the proximity switch 530 is an infrared proximity switch 530, which controls the opening and closing of the electric telescopic rod 510 by sensing the approach distance of the first rectangular slot plate 110.

[0106] For example, in order to improve the sensitivity of the proximity switch 530, an inductive proximity switch 530 can be selected. In this case, a metal plate 540 needs to be set at the bottom of the first rectangular slot plate 110, and the opening and closing of the proximity switch 530 can be controlled by controlling the position of the metal plate 540.

[0107] It should be noted that the use of an inductive proximity switch 530 requires that both the first rectangular slot plate 110 and the second rectangular slot plate 120 be made of non-conductive materials, such as plastic and rubber.

[0108] The inductive proximity switch 530 utilizes the fact that when a conductive object approaches the proximity switch 530, which generates an electromagnetic field, eddy currents are induced inside the object. These eddy currents react with the proximity switch 530, causing changes in the internal circuit parameters of the switch, thereby detecting whether a conductive object is approaching and controlling the switch to open or close.

[0109] The proximity switch 530 can automatically open and close the electric telescopic rod 510 when the first rectangular slot plate 110 moves, thereby tapping the skin near the needle hole to achieve rapid drug absorption. In addition, the tapping process distracts the patient from the sensation of skin touch, effectively avoiding the perception of pain.

[0110] In this embodiment, the cushioning plate 320 is an arc-shaped plate. The arc-shaped plate can better fit the arm and improve comfort.

[0111] For example, the buffer plate 320 is a rubber plate.

[0112] The following describes the working process and principle of the above embodiments:

[0113] The initial state is as follows: the buffer plate 320 does not deform to the sides, the elastic telescopic rod 334 is not extended, the buffer spring 337 is not stretched, the electric telescopic rod 510 is not extended, and the locking spring 139 is not stretched.

[0114] The work steps are as follows:

[0115] The patient wraps the support frame 210 and bandage 420 around the injection site via the fixing block 410. Then, the patient connects the buckle block fixed to the bandage 420 to the buckle opening. This causes the support frame 210 to press the buffer plate 320 against the body via the first connecting block 310. The buffer plate 320 unfolds to both sides under the resistance of the body, causing the buffer plate 320 to simultaneously unfold the second connecting block 331 to both sides. This causes the second connecting block 331 to simultaneously move the bottom end of the first sliding rod 332, which is rotatably connected to it, so that the top end of the first sliding rod 332 is within the groove 211. The first sliding rod 332 moves away from the second connecting block 331, causing the second sliding rod 333 to move away from the second connecting block 331 simultaneously. This causes the second sliding rod 333 to move the telescopic end of the elastic telescopic rod 334 connected to it away from the second connecting block 331. Consequently, the telescopic end of the elastic telescopic rod 334 causes the buffer spring 337 to stretch away from the fixed end of the elastic telescopic rod 334. At the same time, the fixed end of the elastic telescopic rod 334 causes the hinge rod 335 to flip upward simultaneously, thus bringing the support frame 210 and the patient into a relatively stationary state.

[0116] Meanwhile, the first rectangular groove plate 110 and the second rectangular groove plate 120 are both in a relatively static state relative to the patient's body. The elastic force generated after the deformation of the buffer plate 320 and the buffer spring 337 buffers the external force on the syringe 10, avoiding excessive deviation of the syringe 10 that could cause the needle to puncture the subcutaneous tissue around the needle hole, thereby improving the stability of the syringe 10 during injection.

[0117] Subsequently, a person inserts the syringe 10 into the first rectangular groove plate 110, so that the top of the first rectangular groove plate 110 abuts against the outer wall of the syringe 10. The patient then moves the L-shaped limiting block 133 towards the side closer to the syringe 10. This causes the L-shaped limiting block 133 to rotate the rotating rod 132 into the two mounting seats 131. The rotating rod 132 then causes the top of the connecting rod 135 to rotate towards the side closer to the first rectangular groove plate 110. This causes the connecting rod 135 to rotate the locking spring 139, which is rotatably connected to it, around the second mounting post 138 as the axis towards the side closer to the first rectangular groove plate 110. During the rotation of the connecting rod 135, the locking spring 139 is stretched, causing the locking spring 139 to... The spring force generates an inward contraction. When the top of the connecting rod 135 rotates to the side of the first rectangular groove plate 110 above the rotating rod 132, the spring force of the locking spring 139 itself causes the top of the connecting rod 135 to continue rotating until the top of the L-shaped limiting block 133 abuts against the outer wall of the syringe 10. At this point, the locking spring 139 no longer causes the connecting rod 135 to continue rotating, so that the syringe 10 is fixed to the first rectangular groove plate 110 under the abutment action of the L-shaped limiting block 133. By abutting and fixing the syringe 10 with the L-shaped limiting block 133, it is possible to fix syringes 10 of various specifications and also to quickly disassemble the syringes 10, thus improving the flexibility of the device.

[0118] After the syringe 10 is installed on the first rectangular groove plate 110, the patient presses down on the first rectangular groove plate 110, causing the first rectangular groove plate 110 to move towards the body from inside the second rectangular groove plate 120. This causes the first rectangular groove plate 110 to move the needle of the syringe 10 towards the body, allowing the needle of the syringe 10 to be inserted into the body. At the same time, the first rectangular groove plate 110 causes the metal plate 540 to move towards the proximity switch 530, bringing the proximity switch 530 close to the metal plate 540. Subsequently, the proximity switch 530 electrically controls the electric telescopic rod 510 to begin reciprocating up and down. This causes the telescopic end of the electric telescopic rod 510 to drive the tapping frame 520 to repeatedly tap the skin tissue around the needle puncture site. This can accelerate the absorption of the drug by the subcutaneous tissue, avoid the effect of subcutaneous tissue absorption when the drug concentration is too high, and prevent excessive accumulation of high-concentration drugs in the subcutaneous tissue, which can cause swelling and pain at the needle puncture site. At the same time, tapping the skin around the needle puncture site by the tapping frame 520 can effectively divert the patient's attention and reduce the patient's perception of pain.

[0120] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "one" or "multiple" can also be understood to convey either singular or plural usage.

[0121] It should be readily understood that the terms “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0122] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.
