Description

Technical Field

[0001] The invention relates to the technical field of anesthesia apparatus, and in particular to an electrical stimulation anesthesia puncture device. Background Art

[0002] Electrical stimulation anesthesia puncture is an anesthesia technique. An electric stimulator is first used to emit a small electric current to help the doctor locate the patient's nerves, and then puncture anesthesia is performed at the patient's nerve location. At present, an electric push rod is often used to push the needle to ensure stable puncture.

[0003] However, in the prior art, the design of the anesthesia puncture fixation device mainly focuses on the stability of the epidural puncture needle, while the fixation of the patient's body is not sufficient. This design limitation is particularly evident during the puncture process. When the patient moves involuntarily, the puncture will be offset, which directly affects the accuracy and stability of the puncture. Since the puncture needle needs to penetrate the skin and multiple layers of tissue, and a thicker needle is required to deliver a larger amount of anesthetic drugs into the body to ensure sufficient drug dosage to achieve the anesthetic effect, its diameter is usually larger than the daily subcutaneous blood vessel or intramuscular injection needle. Many patients are afraid of needles, especially for needles of this diameter. Many patients usually choose to close their eyes and not observe during the injection. However, this causes the patient to move suddenly when the needle is inserted into the body, causing the needle to cause unnecessary harm to the patient. In addition, the use of anesthesia puncture needles in the pain department is a delicate and process-intensive process. The procedure is cumbersome. Usually, the puncture needle will be properly stored when it is not needed. Only when the patient arrives and is ready to receive anesthesia, the medical staff will take out the puncture needle and start a series of preparations. First, the medical staff needs to take out the puncture needle, and then connect the puncture needle with the connecting tube, syringe and other components. Finally, the prepared puncture needle is fixedly connected to the electric push rod to ensure that the connection between the puncture needle and the electric push rod is firm to prevent displacement or falling off during puncture. This series of operations is not only cumbersome, but also time-consuming. In an emergency, this inconvenience will not only have an adverse effect on the patient's treatment, but also the patient always pays attention to the doctor during this process, which further causes psychological pressure on the patient, causing the patient to be nervous, resulting in accidents during puncture, which can usually only be relieved through the doctor's patient guidance, but it will cause work pressure for the doctor, increase the workload of medical staff, and be more prone to the risk of operational errors.

[0004] To this end, an electrical stimulation anesthesia puncture device is proposed, which can be installed in advance to relieve the patient's tension and ensure smooth puncture. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Reference Figure 1-9, as an embodiment of the present invention, an electric stimulation anesthesia puncture device is provided, including an installer 1, a mounting frame 2 fixedly connected to the top of the installer 1, a telescopic push rod 3 fixedly connected to one side of the mounting frame 2, a closed mounting shell 4 slidably connected to the output end of the telescopic push rod 3, an automatic syringe 5 arranged at the output end of the telescopic push rod 3, a puncture needle 6 clamped at the bottom end of the automatic syringe 5, a reinforcing member 7 rotatably connected to the outside of the automatic syringe 5, a connecting sleeve 8 and a sealing member 9 slidably connected to the inside of the closed mounting shell 4, a spring strip 10 connected between the closed mounting shell 4 and the connecting sleeve 8, a bracket 11 fixedly connected to the bottom end of the connecting sleeve 8, a soft sleeve 12 rotatably connected to the outside of the bottom end of the bracket 11, a slide plate 13 slidably connected to the inside of the closed mounting shell 4, and a return spring 14 connected between the sealing member 9 and the closed mounting shell 4, the connecting sleeve 8 slides vertically, the sealing member 9 slides horizontally, and the sealing member 9 One end extends to the interior of the connecting sleeve 8, and two sealing members 9, spring strips 10, brackets 11, flexible sleeves 12 and return springs 14 are each provided. The two sealing members 9 and the two spring strips 10 are symmetrical about the horizontal axis of the closed mounting shell 4, and the two brackets 11 and the two flexible sleeves 12 are symmetrical about the longitudinal axis of the closed mounting shell 4. When the two sealing members 9 are in contact, they are located at the bottom end of the puncture needle 6. When the connecting sleeve 8 moves up, the two sealing members 9 are driven to slide, and the brackets 11 and the flexible sleeves 12 move down with the connecting sleeve 8. The doctor informs in advance that anesthesia will be performed in the next few seconds when there is contact with an object, so that the patient can have psychological expectations. At the same time, the puncture needle 6 and the automatic injector 5 are installed, fixed and sealed in advance by using the closed mounting shell 4 to avoid panicking of the patient, and the telescopic push rod 3 is cooperated to ensure smooth transportation and operation of anesthesia. At the same time, a limit plate 111 is arranged inside the bracket 11 to limit the downward position of the closed mounting shell 4.

[0033] The automatic injector 5 has a built-in power supply and a push rod, which can be controlled to drive and push the medicine inside the automatic injector 5 in a translational manner, which is consistent with the principle of the telescopic push rod 3. Existing syringes can also be used directly, for example, insulin syringes used by diabetic patients on a daily basis.

[0034] Reference Figure 1-3 The closed mounting shell 4 includes a sleeve shell 41 fixedly connected to the mounting frame 2, an upper support plate 42 fixedly connected to the inside of the sleeve shell 41, a lower support ring 43 fixedly connected to the inside of the sleeve shell 41, and a limiting rod 44 connected between the upper support plate 42 and the lower support ring 43. Two upper support plates 42 and two limiting rods 44 are provided and are symmetrical about the central axis of the sleeve shell 41. Both sides of the connecting sleeve 8 are slidably connected to the outside of the limiting rod 44, and the upper support plate 42 is located above the lower support ring 43.

[0035] Specifically, the upper support plate 42 and the lower support ring 43 are used to limit the upward and downward movement distance of the connecting sleeve 8, and the limiting rod 44 further limits the movement of the connecting sleeve 8 to ensure that the connecting sleeve 8 always moves vertically.

[0036] Among them, when it is used for the first time, the puncture needle 6 is directly installed using a structure of a shell and a driving spring. However, when the shell 41 is in direct contact with the patient, it is used to remind the patient. However, a single shell is large and is prone to wear during long-term testing, and the contact surface with the patient is large. The patient may be in a semi-recumbent posture, which causes the shell 41 to be offset from the patient's contact, and the patient cannot be prevented from moving. At the same time, the patient is under excessive pressure and is prone to injury. Therefore, the bottom is changed to a bracket 11 and a soft sleeve 12, and the soft sleeve 12 can be in stable contact with the patient in different postures of the patient, ensuring that the puncture needle 6 is accurately inserted into the patient's nerve position, reducing the risk and uncertainty in anesthesia operations, and helping to reduce the incidence of medical disputes.

[0037] Reference Figure 1-7 A stabilizing rod 411 is arranged inside the closed mounting shell 4, and a sealing member 9 is slidably connected to the outside of the stabilizing rod 411. The number and position of the sealing member 9 and the stabilizing rod 411 correspond one to one. The sealing member 9 includes an arc block 91 fitted with the connecting sleeve 8, a circular shaft 92 fixedly connected to the bottom end of the arc block 91, and a sealing head 93 fixedly connected to one end of the circular shaft 92 near the puncture needle 6. The return spring 14 is connected between the circular shaft 92 and the sleeve shell 41. The circular shaft 92 is provided with an inner circular groove 921. The stabilizing rod 411 is located inside the inner circular groove 921. A short notch 931 is provided on the side of the sealing head 93 near the slide plate 13.

[0038] Specifically, the stabilizing rod 411 is located inside the inner circular groove 921 to provide support for the circular shaft 92, so that the sealing member 9 as a whole can only move horizontally along the stabilizing rod 411, and when the two sealing heads 93 are fitted together, the bottom end of the puncture needle 6 will be located on the top of the two sealing heads 93, and the sealing heads 93 are used to wrap the bottom end of the puncture needle 6, and the short notch 931 of the sealing head 93 is open, thereby cooperating with the shell 41 to place the sealing member 9 in a hygienic and safe environment.

[0039] Reference Figure 2-5 The reinforcement 7 includes a semi-ring 71 rotatably connected to the outside of the automatic injector 5, and two fixing bars 72 respectively clamped on both sides of the semi-ring 71. A path groove 711 is provided inside the semi-ring 71. The top end of the path groove 711 is closed and the bottom end is open, so that the automatic injector 5 can be separated from the path groove 711 from the bottom end, and can also enter the path groove 711 from the bottom end of the path groove 711.

[0040] Specifically, during use, the connecting sleeve 8 is frequently moved up and down, which causes it to wear and deviate. When the telescopic push rod 3 is extended, the connecting sleeve 8 will produce a displacement sound and loosen. The displacement of the connecting sleeve 8 will cause the bracket 11 to squeeze the closed mounting shell 4, causing wear on the contact surface between the bracket 11 and the closed mounting shell 4, causing the soft sleeve 12 to deviate, which can easily cause discomfort to the patient. Therefore, the half ring 71 and the fixing strip 72 are used to fix the connecting sleeve 8 to further ensure the safety and effectiveness of the anesthesia operation, improve the safety of the patient and reduce the discomfort during the postoperative recovery period.

[0041] Reference Figure 2-6 A circular notch 81 and a square notch 82 are provided on the top of the connecting sleeve 8. Two square notches 82 are provided and are located on both sides of the circular notch 81. The square notch 82 is interconnected with the circular notch 81, and the spacing between the two square notches 82 is greater than the spacing between the two fixing bars 72, so that the fixing bars 72 can directly pass through the square notch 82 to reach the inside of the connecting sleeve 8. Slide notches 83 are provided on both sides of the bottom end of the connecting sleeve 8. One end of the round shaft 92 passes through the slide notch 83, and the round shaft 92 can slide inside the slide notch 83. Therefore, when the connecting sleeve 8 moves up, the sealing member 9 as a whole will not affect the movement of the connecting sleeve 8, and the round shaft 92 can slide inside the round shaft 92.

[0042] Reference Figure 2-6 The inside of the top of the connecting sleeve 8 is an inner circular area 801, and the height of the inner circular area 801 is equal to the height of the fixing strip 72. The fixing strip 72 will move to the inside of the inner circular area 801. In order to ensure that the soft sleeve 12 is stable before the puncture needle 6 is anesthetized, the connecting sleeve 8 is fixed by using the semi-ring 71 and the fixing strip 72 to ensure that the puncture needle 6 can accurately enter the patient's nerve position. The outside of the connecting sleeve 8 is an outer facade 802, and the outer facade 802 is in contact with the inner side of the arc block 91, so that the outer facade 802 is used to squeeze the sealing part 9, so that the sealing part 9 is translated after being refueled. A vertical notch 803 is provided on the side of the connecting sleeve 8 close to the slide plate 13, and the vertical notch 803, the short notch 931, the slide plate 13 and the puncture needle 6 are parallel.

[0043] An outer magnetic ring 51 is arranged on the top of the automatic injector 5, a hook ring 52 is arranged on the side of the automatic injector 5 close to the slide 13, and a pressure strip 53 is arranged on the side of the automatic injector 5 away from the slide 13. The pressure strip 53 is located inside the path groove 711, and the outside of the pressure strip 53 is treated with high friction.

[0044] Specifically, since the automatic syringe 5 and the puncture needle 6 need to be replaced, in order to quickly replace them, one side of the closed mounting shell 4 can be opened by sliding the slide plate 13. Since the vertical slot 803, the short slot 931, the slide plate 13 and the puncture needle 6 are parallel, the automatic syringe 5 can be pulled by hooking the hook ring 52 with fingers, so that the automatic syringe 5 is separated from the telescopic push rod 3, and the automatic syringe 5 and the puncture needle 6 are taken out for replacement. After the replacement is completed, the return spring 14 can be closed using the slide plate 13.

[0045] Reference Figure 1-9 The output end of the telescopic push rod 3 is an extension rod 31 and a support slot plate 32 . The support slot plate 32 fixes the bottom end of the extension rod 31 . The support slot plate 32 is located above the outer magnetic ring 51 . The support slot plate 32 is located inside the casing 41 .

[0046] Specifically, when replacing the automatic syringe 5 and the puncture needle 6, the outer magnetic ring 51 is used to generate adsorption with the support slot plate 32 to stabilize the automatic syringe 5. At the same time, when replacing the automatic syringe 5, the automatic syringe 5 is pushed hard so that the automatic syringe 5 drives the puncture needle 6 to the center position of the closed mounting shell 4. The middle part of the support slot plate 32 is a through groove. By pushing the pressure strip 53 hard, the automatic syringe 5 can slide on its surface, allowing medical staff to complete anesthesia preparation work faster, saving valuable time and manpower resources.

[0047] Reference Figure 1-9 The inner side of the arc block 91 has the same shape as the outer facade 802, so that the outer facade 802 of the connecting sleeve 8 can squeeze the arc block 91, and the outer facade 802 is divided into an inclined surface 8021 and a vertical surface 8022, and the inclined surface 8021 is located above the vertical surface 8022. At this time, when the connecting sleeve 8 is blocked by the upper support plate 42 and cannot move, the arc block 91 will be squeezed and moved immediately, and the inclined surface 8021 is inclined in a direction close to the center of the connecting sleeve 8. When the arc block 91 is located on the vertical surface 8022 of the connecting sleeve 8, it will not move and will always be in a squeezed state, ensuring that the sealing head 93 will not block the puncture needle 6.

[0048] Reference Figure 1-9The installer 1 includes a bed 101, roller drivers 102 fixed on both sides of the bed 101, horizontal drivers 103 slidably connected to the roller drivers 102 at both ends, and a controller 104 fixedly connected to one side of the horizontal driver 103. One side of the mounting frame 2 is slidably connected to the top of the horizontal driver 103, wherein the patient is located on the top of the bed 101, and the horizontal driver 103 can slide inside the roller driver 102, and at the same time, the roller driver 102 can be driven directly by an external driver to drive the roller driver 102, so that the roller driver 102 drives the horizontal driver 103 to move, and the horizontal driver 103 will drive the mounting frame 2 to move, so that the puncture needle 6 moves accordingly, so that the position of the puncture needle 6 is switched. In addition, the roller driver 102 is composed of a roller screw and a limiting round rod, and is also equipped with a driving motor.

[0049] The working principle of the present invention is as follows: the position of the mounting frame 2 is adjusted by the horizontal driver 103, thereby driving the components connected to the mounting frame 2 to perform translational adjustment, and then after reaching the appropriate position, the extension rod 31 and the support slot plate 32 are pushed downward by the telescopic push rod 3, and since the casing 41 is supported by the support slot plate 32, when the support slot plate 32 moves downward, the casing 41 moves downward synchronously under the influence of gravity, and when the casing 41 moves, it drives the internal structure to move synchronously, and the outer magnetic ring 51 is adsorbed with the support slot plate 32, so that the automatic injector 5 and the puncture needle 6 also move downward with the support slot plate 32, and when the automatic injector 5 moves downward, the reinforcing member 7 is driven downward as a whole through the pressure strip 53, and when the bracket 11 and the flexible sleeve 12 move downward with the casing 41, since the flexible sleeve 12 is located at the bottom The position will first contact the patient, so that the patient can know the information of the upcoming anesthesia after the contact, and then because the soft sleeve 12 is blocked after contacting the patient, the soft sleeve 12 and the bracket 11 cannot move synchronously, and the telescopic push rod 3 is still pushing the sleeve shell 41 to move downward. At this time, because the soft sleeve 12 and the bracket 11 are blocked, the connecting sleeve 8 cannot move, so that the connecting sleeve 8 compresses the spring strip 10, and the sleeve shell 41 will still drive the sealing member 9 to move downward synchronously as a whole. At this time, the arc block 91 moves downward because the connecting sleeve 8 cannot move. When moving downward, the arc block 91 is squeezed by the external facade 802 of the connecting sleeve 8 and moves horizontally. At this time, both arc blocks 91 will move horizontally, and at the same time, the arc block 91 will drive the round shaft 92 when moving. The two sealing heads 93 move synchronously, and the round shaft 92 slides on the outside of the stabilizing rod 411 and squeezes the return spring 14 at the same time. The directions of the synchronous movement of the two sealing heads 93 are opposite, so that the two sealing heads 93 move away from each other and no longer fit together. When the limit plate 111 of the bracket 11 contacts the bottom end of the sleeve shell 41, the sleeve shell 41 will also be blocked and unable to move. The top surface of the connecting sleeve 8 will be in contact with the upper support plate 42. At this time, the semi-ring 71 and the fixing strip 72 will enter the inner circle area 801 of the connecting sleeve 8 from the circular notch 81 and the square notch 82. At this time, the semi-ring 71 will be blocked by the connecting sleeve 8 and cannot move downward, but the supporting groove plate 32 will continue to push the automatic injector 5 and the puncture needle 6 to move downward. At this time, the pressure strip 53 provided on the automatic injector 5 will The path groove 711 is squeezed, causing the semi-ring 71 and the fixing strip 72 to rotate, and then the semi-ring 71 is used to fix the connecting sleeve 8, and the bracket 11 and the flexible sleeve 12 are fixed to the bottom end of the connecting sleeve 8, so that the three are stable. At this time, the relative distance between the flexible sleeve 12 and the patient is fixed, and the sealing member 9 is fixed as a whole. At this time, the automatic syringe 5 and the puncture needle 6 continue to move downward, and the puncture needle 6 will contact the patient, and then the puncture needle 6 will be used to complete the anesthesia work, and then the telescopic push rod 3 drives the support groove plate 32 and the extension rod 31 to move back, and the automatic syringe 5 and the puncture needle 6 will move back synchronously at this time, and the pressure strip 53 set on the automatic syringe 5 will enter the interior of the semi-ring 71, and the pressure strip 53 is used to squeeze the path groove 711, so that the semi-ring 71 and the fixing strip 72 rotate.At the same time, the semi-ring 71 and the fixing strip 72 move upward with the automatic injector 5. When the supporting groove plate 32 contacts the inner part of the top of the sleeve 41, the sleeve 41 moves upward with the supporting groove plate 32, and the connecting sleeve 8 gradually resets with the upward movement of the sleeve 41, so that the connecting sleeve 8 no longer squeezes the arc block 91, and the return spring 14 rebounds to make the round shaft 92 move back, and the two sealing heads 93 fit again to seal the bottom end of the puncture needle 6. Finally, the soft sleeve 12 and the bracket 11 move with the connecting sleeve 8 and no longer contact the patient, thereby completing the work.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
