Description

Technical Field

[0001] The invention relates to a slot-guided needle head auxiliary needling device, belonging to the technical field of surgical instruments. Background Art

[0002] In clinical practice, acupuncture and injection are commonly used treatments. Acupuncture requires a high level of skill, requiring extensive practice to master the technique—the ability to easily and quickly insert the needle tip of a syringe into a vein beneath a patient's skin. Without systematic, professional training, the average person is unlikely to actually perform an acupuncture injection. However, daily life often presents emergencies. For example, in remote locations, even if emergency medications are prepared before departure, lacking acupuncture skills, one may be forced to wait for help, wasting a potentially life-saving opportunity. Another example is mountain hiking, a popular travel activity for many parents and children. However, in the event of an emergency such as a snake, rat, or insect bite, the climb is already exhausting, and rushing the patient to a hospital requires significant time and manpower. If emergency supplies could be brought to bear in emergencies, allowing patients to be treated locally without needing to go to a hospital, thousands of lives could be saved, avoiding unnecessary travel delays. In the process of needle-assisted design and product development, some people have tried this, such as: a detachable infusion port vertical needle-assisted device, application number: CN202321897431.3; a pediatric nursing needle-assisted device, application number: CN202222425445.7; a pediatric nursing needle-assisted device, application number: CN202220970671.0; an emergency needle-assisted device, application number: CN202110961422.5 A vascular acupuncture auxiliary device, application number: CN202021574906.1; A medical wrist acupuncture auxiliary device, application number: CN202020748549.X; A pediatric nursing acupuncture auxiliary device, application number: CN201921607761.8; A pediatric clinical acupuncture auxiliary device, application number: CN201921572190.9; A pediatric clinical acupuncture auxiliary device, application number: CN201821341581.5. In some aspects, these patents can play their own role and solve certain technical difficulties. However, they all have problems of one kind or another. Some of them are more complex and difficult to operate in practice, while others are only for special groups such as infants and young children, and they cannot be applied universally.Therefore, how can we provide people with a needle-insertion assisting device so that everyone can quickly master the needle-insertion technique and quickly complete the injection of the drug solution after reading the instruction manual? Therefore, a telescopic rod is used to fix the shovel-shaped head. The shovel-shaped head is provided with structural components such as a groove guide plate, a skin-exposing hole, a pulse compression plate, and a pulse compression soft blade. The operator is allowed to place the injection needle of the syringe close to the needle guide groove in the center of the upper surface of the groove guide plate and insert it along the groove, just into the patient's vein without piercing the guide plate. With the help of the pulse compression plate, the flow is blocked, so that the vein bulges on the skin surface due to blood accumulation and becomes more obvious. Then, the operator holds the syringe in the other hand and inserts it along the needle guide groove. The injection needle can be smoothly inserted into the patient's vein, thereby achieving the purpose of quickly mastering the needle-insertion technique and treating the patient on the spot as long as the operator reads the instruction manual regardless of whether he has needle-insertion experience. Therefore, it is necessary to invent a needle-insertion assisting device with a groove guide needle. Summary of the Invention

DETAILED DESCRIPTION

[0015] Example 1

[0016] The slot guide needle auxiliary needle insertion device consists of a slot guide plate 1, a skin exposure hole 2, a pulse compression soft blade 3, a vein 4, a pulse compression plate 5, a shovel-shaped head 6, an inner stopper 7 on the telescopic rod tube, a telescopic rod 8, a lower outer stopper 9 on the telescopic rod tube, a telescopic rod tube cavity 10, a handle rubber cover 11, a syringe 12, an injection needle 13, a volume scale 14, a syringe outer tube 15, a syringe cavity 16, an end wing of the syringe outer tube 17, a syringe piston rod 18, a needle guide groove 19, a lower bottom surface 20 of the slot guide plate, a rear bottom surface 21 of the slot guide plate, a side surface 22 of the slot guide plate, an upper surface 23 of the slot guide plate, a needle release seam 24, and a pressure-assisting sheet 25. The slot guide plate 1 is a guide plate that allows the operator to put the injection needle 13 of the syringe close to the needle guide groove 19 in the center of the upper surface 23 of the slot guide plate and insert it along the groove, so that it can be inserted into the patient's vein without being deviated or penetrated. With the help of the pulse compression plate 5, the flow is pressed and blocked, so that the vein 4 bulges with blood on the skin surface and becomes larger. When it is clearly visible, the other hand holds the syringe 12 and inserts it along the needle guide groove 19, so that the injection needle 13 can be smoothly inserted into the patient's vein; the groove guide plate 1 is made of plastic, stainless steel, aluminum alloy, or copper, with one side thicker and the other side thinner, thus forming an overall wedge-shaped structure, which is arranged at the straight edge of the skin-exposing hole 2, that is, the intersection of the lower bottom surface 20 of the groove guide plate and the upper surface 23 of the groove guide plate is the straight edge of the skin-exposing hole 2; the groove guide plate 1 is arranged on the upper surface of the shovel-shaped head 6, with the thicker side at the rear and the thinner side at the front; the groove guide plate 1 is composed of the needle guide groove 19, the lower bottom surface 20 of the groove guide plate, the rear bottom surface 21 of the groove guide plate, the side surface 22 of the groove guide plate, and the upper surface 23 of the groove guide plate. The needle guide groove 19 is a groove that runs through the upper surface 23 of the groove guide plate in the front and back direction and is located in the center of the upper surface 23 of the groove guide plate. The cross section of the needle guide groove 19 is semicircular, and the diameter of the semicircular needle guide groove 19 is 0.5-1.5 mm; Since the groove guide plate 1 is wedge-shaped as a whole, it has a groove guide plate bottom surface 20, a groove guide plate rear bottom surface 21, a groove guide plate side surface 22, and a groove guide plate upper surface 23, wherein the groove guide plate bottom surface 20 is the surface below the groove guide plate 1, which can be glued together with the upper surface of the shovel-shaped head 6 with an adhesive, or it can be integrated with the shovel-shaped head 6, which is a structure that connects the groove guide plate 1 and the shovel-shaped head 6 together; the groove guide plate rear bottom surface 21 is the surface behind the groove guide plate 1, and a semicircular notch is formed in the center of the upper edge, which is actually the rear end of the guide pin groove 19. Since the groove guide plate rear bottom surface 21 has A certain height, so the needle guide groove 19 made in the center of the upper surface 23 of the groove guide plate will form an inclination angle on the skin surface during actual use, thereby ensuring that the injection needle 13 is more effectively inserted into the vein 4; the side surface 22 of the groove guide plate is the surface on both sides of the groove guide plate 1, which is a right triangle. The smallest angle of the side surface 22 of the groove guide plate is at the front end, and the angle is relatively small, generally set to 10°-20°, to ensure that the injection needle 13 has sufficient inclination before inserting into the vein 4; the upper surface 23 of the groove guide plate is the surface above the groove guide plate 1, and a needle guide groove 19 is set in the center. The skin-exposing hole 2 is a space for the operator to see the patient's skin clearly and expose the blood vessels clearly in real time when pricking or observing the blood vessels. It is located in the center of the widest part of the shovel-shaped head 6 and is semi-elliptical as a whole, that is, the front edge is an arcuate edge, and the rear edge is a short diameter passing through the center point of the ellipse. The long diameter of the ellipse is 1.5-2 cm and the short diameter is 1-1.5 cm; a notch is set in the center of the top front end of the arcuate edge, and the notch is formed by the pressure-assisting sheet 25 at the rear of the needle-releasing seam 24, with a width of 0.4-1.2 mm; the center of the short diameter of the rear edge of the skin-exposing hole 2 is the front end of the needle-leading groove 19; that is to say, the skin-exposing hole 2 is located between the groove guide plate 1 and the compression plate 5; the compression plate 5 is a structure composed of two wedge-shaped adjacent pieces at the front and upper part of the shovel-shaped head 6 to form a needle-releasing seam 24 in the center; the compression plate 5 is made of plastic, stainless steel, aluminum alloy, or copper, and is provided with a centrally concave pressure-assisting sheet 25 on the inside, and all the pressure-assisting sheets 25 are extended in the needle-releasing seam 24 to assist pressure The thin sheet 25 is made of plastic and has a thickness of 0.05-0.1 mm. The needle-releasing slit 24 is a slit in the front-to-back direction of the center of the compression plate 5 and has a width of 1-3 mm. A pair of pressure-assisting thin sheets 25 are provided at the bottom of the needle-releasing slit 24, and the two pressure-assisting thin sheets 25 are symmetrically arranged on both sides of the bottom of the needle-releasing slit 24. The pressure-assisting thin sheets 25 on both sides of the bottom of the needle-releasing slit 24 are closer at the front end of the needle-releasing slit 24 and farther at the rear end of the needle-releasing slit 24. In this way, even if the needle-releasing slit 24 has a certain width, when the compression plate 5 presses the vein 4, it can still exert a certain pressing function, so that the vein 4 can be pressed down. At the same time, because the pressure-assisting thin sheets 25 are thin, elastic and tough, when the injection needle 13 is inserted into the vein 4, it can easily detach from the needle-releasing slit 24 without being constrained or interfered by the shovel-shaped head 6. The soft compression blade 3 is a layer of silicone thin sheet provided on the upper and lower surfaces of the front of the compression plate 5. The thickness of the silicone is 0.1-0.2 mm, because silicone has strong elasticity and toughness, when the compression plate 5 is pressed on the skin, the silicone surface can form a strong buffer, thereby ensuring that the vein 4 can be pressed, but the skin will not be damaged by cutting due to the thin front edge of the compression plate 5; the vein 4 is a vein that can be clearly seen when pressing on the back of the hand, scalp and other parts of the patient to be punctured. When injection is required, the medicine in the syringe 12 can be injected into the vein 4; when the compression plate 5 is pressed on the skin outside the front part of the vein 4 in the direction of the heart, the vein is blocked due to the pressing and squeezing. 4, the vein 4 is clearly exposed in the skin-exposing hole 2 under the filling of blood, which allows the operator to easily insert the injection needle 13 into the vein 4; the shovel-shaped head 6 is fixed to the groove guide plate 1 and the compression plate 5, pressing the skin above the vein 4 to fully expose the vein 4, and connecting the groove guide plate 1 and the compression plate 5 to the structure above the telescopic rod 8. The shovel-shaped head 6 is in the shape of a shovel with the blade facing obliquely forward. The base is fixed to the upper end of the telescopic rod 8, and a semi-elliptical skin-exposing hole 2 is set in the center; the shovel-shaped head 6 is made of plastic, stainless steel, aluminum alloy, copper The telescopic rod 8 is a multi-section metal rod that can be telescopic. Taking three sections as an example, the top of the innermost telescopic rod 8 is fixedly connected to the lower end of the shovel-shaped head 6, and a telescopic rod tube lower outer stop 9 is provided on the outer surface of its lower end. The telescopic rod tube lower outer stop 9 is a solid metal ring with a thickness of about 0.2-0.5 mm; the inner surface of the top of the middle telescopic rod 8 is provided with a ring-shaped telescopic rod tube upper inner stop 7, and the telescopic rod tube upper inner stop 7 is a solid metal ring with a thickness of about 0.2-0.5 mm; the telescopic rod tube upper inner stop 7 and the outer surface of the lower end of the innermost telescopic rod 8 are connected. The lower outer stop 9 of the telescopic rod tube is engaged with each other, thereby ensuring that the innermost telescopic rod section 8 can move up and down within the middle telescopic rod section 8 without slipping out; the outermost telescopic rod section 8 is provided with only one telescopic rod tube upper inner stop 7 on the inner side of the top, which engages with the telescopic rod tube lower outer stop 9 on the outer surface of the lower end of the middle telescopic rod section 8 to prevent slipping; at the same time, a handle rubber cover 11 is provided on the outer side of the lower part of the outermost telescopic rod section 8. The handle rubber cover 11 is made of rubber with a rough surface for easy grip. The thickness of the rubber used for the handle rubber cover 11 is 0.2-0.5 mm; the telescopic rod lumen 10 is the lumen of the telescopic rod 8, and the telescopic rod inside can move up and down in the lumen of the outer telescopic rod; the syringe 12 is a commercially available syringe that can inject liquid medicine into the patient's blood vessels. The main component is glass or plastic. The syringe 12 consists of an injection needle 13, a volume scale 14, a syringe outer barrel 15, a syringe cavity 16, a syringe outer barrel end wing 17, and a syringe piston rod 18. The injection needle 13 is a commercially available syringe needle. The material used when making the injection needle 13 is SUS304 and SUS316L stainless steel. The free end has a tip made of a bevel, which is very sharp and easy to pierce into the vein 4; the volume scale 14 is marked on the outer surface of the syringe outer barrel 15 along the long axis direction of the syringe outer barrel 15 The volume scale is 1 ml, and each larger scale point is 1 ml; the syringe outer barrel 15 is the outer wall of the syringe 12, and the front end of the syringe outer barrel 15 is provided with a central connecting protrusion with a hole that can tightly cover the injection needle 13. The rear end of the syringe outer barrel 15 is open, which is convenient for inserting the syringe piston rod 18 into the syringe cavity 16; a syringe outer barrel end wing 17 is provided on each side of the rear end opening of the syringe outer barrel 15, that is, the two syringe outer barrel end wings 17 are symmetrically arranged on both sides of the rear end opening of the syringe outer barrel 15. The function of the syringe outer barrel end wings 17 is to facilitate the operator to hold the syringe 12 in hand when using the syringe 12; the syringe piston rod 18 needs to be inserted into the syringe cavity 16 to provide thrust for the syringe cavity 16 to ensure that the liquid medicine in the syringe 12 is pushed into the vein 4. When using a slotted needle-assisted acupuncture device, to prevent infection, the spade-shaped tip 6 must be sterilized with 75% alcohol before use. This means soaking for 5 minutes, then removing the spade-shaped tip 6. Once the alcohol evaporates, the injection can be guided. Even operators with no acupuncture experience can use this tool according to the instructions, making acupuncture a simple and routine task, eliminating the need for extensive manpower, material, and financial resources, and eliminating the need for hospital visits. This is particularly useful when administering injections to patients under extreme conditions.
