Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a gunshot wound auxiliary analgesia device. Background Art

[0002] One thing that makes military hospitals different from regular hospitals is that they often receive patients with gunshot wounds. Gunshot wounds are hollow wounds formed on the surface of the human body by the strong explosive force of a bullet when it comes into contact with the human body. They can cause serious damage to the muscles of the human body. Therefore, compared with other wounds, gunshot wounds cause several times more pain. Conventional anesthesia is performed through a syringe, and its effect focuses more on the nervous system away from the wound, and does not significantly reduce the pain at the wound. Summary of the invention

[0003] The purpose of the present invention is to provide a gunshot wound auxiliary analgesia device.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A gunshot wound auxiliary analgesia device comprises a needle and a syringe, the syringe comprises a nipple and a syringe, a piston and a piston push rod, the syringe comprises an inner syringe and an outer syringe, the piston push rod is arranged in the inner syringe, and the nipple is connected to the inner syringe, the bottom of the inner syringe is provided with a notch connected to the outer syringe, the outer wall of the outer syringe is provided with an annular floating plate with an outer diameter consistent with the inner diameter of the outer syringe, the bottom of the outer syringe is provided with a leakage hole connected to the outside world, and the piston push rod is connected to a linkage structure that enables the annular floating plate and the piston to move upward synchronously.

[0006] Furthermore, the linkage structure includes an annular cylinder plate arranged on the inner syringe and sleeved on the piston push rod, and at least two guide rods arranged in the outer syringe and along the axial direction of the outer syringe. The inner syringe is provided with a sliding groove parallel to the guide rod and corresponding to the guide rod one by one. The upper end of the guide rod is fixedly connected to a connecting rod passing through the sliding groove and fixedly connected to the annular cylinder plate. The lower end of the guide rod is movably connected to the annular floating plate, and the annular floating plate can move along the guide rod.

[0007] Furthermore, the leakage holes are provided in multiple rows and are distributed along the circumferential direction of the outer syringe.

[0008] Furthermore, there are at least two notches evenly distributed along the circumferential direction of the inner syringe.

[0009] Furthermore, the thickness of the annular floating plate is not less than the height of the notch on the inner syringe.

[0010] Furthermore, the upper end of the slide groove extends to the outside of the upper end of the inner syringe.

[0011] Furthermore, a through hole with an inverted T-shaped cross section is provided on the annular floating plate corresponding to each guide rod, the guide rod is an inverted T-shaped structure, and the lower end surface of the guide rod is in the same horizontal plane as the lower end surface of the annular floating plate.

[0012] Beneficial effects:

[0013] The present invention improves the conventional syringe. Through the notch arranged on the inner syringe, when the anesthetic is inhaled, the anesthetic is inhaled in both the inner syringe and the outer syringe. When anesthesia and analgesia are performed, the anesthetic in the inner syringe is injected into the patient's muscle under the push of the piston; the anesthetic in the outer syringe flows out from the leakage hole under the action of the reverse thrust, and the outflowing anesthetic contacts the wound wall formed by the gunshot wound, paralyzes the nerves of the wound wall, thereby reducing the pain of the gunshot wound.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figure 1 and Figure 2 As shown, the gunshot wound auxiliary analgesia device of the present invention is an injection needle structure, including a needle and a syringe, and the syringe includes a nipple 1 and a syringe 2, a piston 3 and a piston push rod 4; Figure 1 As shown, the syringe adopts a double-layer structure, including an inner syringe 21 and an outer syringe 22, the piston push rod is arranged in the inner syringe, and the nipple is connected to the inner syringe.

[0022] like Figure 4 As shown, a notch 211 communicating with the outer syringe is provided at the bottom of the inner syringe, and at least two notches are evenly distributed along the circumferential direction of the inner syringe; Figure 3 As shown, a circular floating plate 5 having an outer diameter consistent with the inner diameter of the outer syringe is provided in the outer syringe around the outer wall of the inner syringe. Figure 2 and Figure 3 As shown, the piston push rod is connected with a linkage structure 6 which enables the annular float plate to move upward synchronously with the piston, that is, when the piston push rod drives the piston to move upward, the linkage structure can drive the annular float plate to move upward synchronously, and when the syringe is not in use, the annular float plate is at the lowest end in the outer syringe, and in this regard, the thickness of the annular float plate is limited, which is not less than the height of the notch on the inner syringe, so that when not in use, the annular float plate seals the notch, and when the annular float plate moves upward synchronously with the piston, the anesthetic absorbed by the needle first enters the inner syringe, and at this time the notch gradually opens, the inner syringe is connected to the outer syringe, and a portion of the anesthetic will pass through the notch into the outer syringe.

[0023] Furthermore, if Figure 5 As shown, a leakage hole 221 connected to the outside world is provided at the upper bottom position of the outer syringe. The leakage holes are provided in multiple rows and are distributed along the circumferential direction of the outer syringe. In order to allow the anesthetic to flow out of the leakage holes, the annular float plate is movably connected to the linkage structure. In this way, when the piston push rod squeezes the anesthetic in the inner syringe downward, the anesthetic in the inner syringe is normally injected from the needle tip, and the anesthetic in the inner syringe can squeeze the anesthetic in the outer syringe to form an upward thrust. The upward thrust causes the annular float plate to move upward until it moves to above the leakage hole. At this time, the anesthetic in the outer syringe will flow from the leakage hole to the outside. Because the invention is aimed at gunshot wounds, the present application can be placed in the wound during anesthesia injection, so that the anesthetic flowing out of the leakage hole will contact the inner wall of the gunshot wound, and the anesthetic will anesthetize the nervous system on the inner wall of the wound.

[0024] In this regard, the linkage structure in the present invention is further described in detail:

[0025] like Figure 2 As shown, the linkage structure includes a circular cylinder plate 61 arranged on the inner syringe and sleeved on the piston push rod, and at least two guide rods 62 arranged parallel to the axial direction of the outer syringe are arranged in the outer syringe. Figure 3As shown, a slide groove 212 parallel to the guide rod and corresponding to the guide rod one by one is provided on the inner syringe, and the upper end of the slide groove extends to the outside of the upper end of the inner syringe; the upper end of the guide rod is fixedly connected with a connecting rod 63 passing through the slide groove and fixedly connected to the annular cylinder plate, and the lower end of the guide rod is movably connected with the annular floating plate, and the annular floating plate can move along the guide rod.

[0026] In the above, the annular cylinder plate can be fixedly connected to the piston push rod, or can be movably connected. In order to avoid the possibility that the synchronous movement of the annular cylinder plate and the piston push rod will drive the annular floating plate when the piston push rod pushes the anesthetic downward, the present invention preferably has the annular cylinder plate movably connected to the piston push rod, and a plurality of reinforcing ribs fixed to the piston push rod are provided between the annular cylinder plate and the piston, and the annular cylinder plate is placed on the plurality of reinforcing ribs. In this way, the piston push rod drives the piston to move upward, and due to the action of the reinforcing ribs, the annular cylinder plate synchronously drives the movement of the annular floating plate.

[0027] The connection relationship between the circular floating plate and the guide rod is described as follows:

[0028] like Figure 2 As described, a through hole with an inverted T-shaped cross section is provided on the annular float plate corresponding to each guide rod, the guide rod is an inverted T-shaped structure, and the lower end surface of the guide rod is in the same horizontal plane as the lower end surface of the annular float plate, the larger diameter portion of the guide rod is just embedded in the larger diameter portion of the through hole, and the remaining portion of the guide rod extends through the through hole toward the connecting rod. In this way, when an injection is performed, the anesthetic in the outer syringe will push the annular float plate to move upward along the guide rod, and when the annular float plate moves above the leakage hole, the anesthetic can flow out from the leakage hole. The purpose of the design of the present invention is to ensure that the anesthetic flowing out of the leakage hole is in the wound of the gunshot wound, and the amount of anesthetic can be guaranteed. If the wound is directly sprayed or cleaned with an injection needle or other equipment, the anesthetic at this time is large and will be harmful to the patient's body.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
