Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a rapid sedation and analgesia treatment needle. Background Technology

[0002] Acute trauma occurring outside of hospitals and combat trauma under field conditions often result in severe injuries, accompanied by blood loss, shock, and intense pain. Studies have shown that, excluding those who die immediately, a significant reason for failed resuscitation efforts is the imbalance in the body's regulation of the acute traumatic stress response during transport and the initial stages of standardized hospital treatment, leading to secondary, fatal organ dysfunction. In other words, sedation, analgesia, and stress relief are essential life-saving measures on top of basic life support, but their implementation is currently difficult and their understanding is insufficient.

[0003] Therefore, this invention proposes a rapid sedation and analgesia treatment acupuncture that combines traditional Chinese medicine wrist and ankle acupuncture analgesia with drug analgesia, thereby further improving the sedation and analgesia effect. Summary of the Invention

[0004] The present invention aims to provide a rapid sedation and analgesia treatment needle that combines traditional Chinese medicine wrist and ankle acupuncture analgesia with drug analgesia to further improve the sedation and analgesia effect, and solves the shortcomings of the existing technology in sedation and analgesia.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The basic technical solution provided by this invention is:

[0007] A rapid sedation and analgesia treatment needle includes a needle tip, a needle handle, and a piston cylinder. The needle tip has an elastic hollow structure and a sealing membrane is provided inside the needle tip. The needle handle has a first drug chamber inside. The piston cylinder is slidably fitted inside the first drug chamber and has a second drug chamber inside. Both the first and second drug chambers are used to hold anesthetic drugs. The front end of the piston cylinder has an opening that connects the first and second drug chambers. The rear end of the piston cylinder is connected to a control rod that extends to the outside of the needle handle and is connected to a push block.

[0008] The principle of the basic technical solution: The overall structure of this treatment needle is based on the traditional Chinese medicine wrist-ankle acupuncture structure. When providing analgesia to the injured, the needle tip is first inserted into the corresponding position according to the patient's specific condition, i.e., subcutaneous needle embedding. Both the first and second drug chambers are filled with anesthetic drugs. After embedding the needle, pressing the push block at the tail causes the anesthetic drug in the first drug chamber to break through the sealing membrane. The piston cylinder moves forward, injecting the anesthetic drug in the first drug chamber into the subcutaneous tissue for anesthesia and analgesia. After all the anesthetic drug in the first drug chamber has been injected, the piston cylinder is located at the front end inside the needle handle. Due to gravity, the anesthetic drug in the second drug chamber begins to slowly flow out from the opening, thus allowing the anesthetic drug in the second drug chamber to slowly flow out over a certain period of time after the injection of the anesthetic drug in the first drug chamber, providing continuous anesthesia. After the wrist-ankle needle is placed, it is fixed with paper tape or similar materials for continuous analgesia.

[0009] The beneficial effects of the basic technical solution are as follows: The therapeutic needle of this invention combines wrist-ankle acupuncture analgesia from traditional Chinese medicine with drug analgesia. Wrist-ankle acupuncture is a method of treating systemic diseases by needling specific points on the wrist or ankle. It has the characteristics of single point selection, simple operation, minimal damage to the body, safety, and no needle sensation. Combining wrist-ankle acupuncture analgesia and drug analgesia further enhances its sedative and analgesic effect. After the drug in the first drug chamber is injected, the drug in the second drug chamber can continuously flow out for a certain period of time, thereby providing continuous analgesia. The insertion of wrist-ankle acupuncture in traditional Chinese medicine itself has a continuous analgesic effect. With the continuous inflow of drug analgesia, it can provide a continuous and stronger analgesic effect. The therapeutic needle of this invention has a simple structure, is easy to operate, and can quickly and continuously sedate and analgesize the injured. The method of using the therapeutic needle of this invention follows the method of wrist and ankle acupuncture in traditional Chinese medicine. The time, location and technique of embedding the needle in wrist and ankle acupuncture all affect the analgesic effect. Therefore, the therapeutic needle of this invention can "prescribe the right medicine for the right condition" according to the specific situation of the injured person, and further ensure the analgesic and sedative effect.

[0010] Preferably, a high-pressure chamber is provided inside the needle handle, containing high-pressure gas. The high-pressure chamber is located at the tail end of the piston cylinder, which has several through holes. A number of sealing rods are connected to the tail end of the needle handle corresponding to these through holes, and the sealing rods are used to seal the through holes.

[0011] With the above setup, after the piston cylinder is pushed to the top of the needle handle, the sealing rod will disengage from the through hole. The through hole connects the second drug chamber with the high-pressure chamber. Under the combined action of gravity and high pressure, the drug in the second drug chamber can be continuously pushed to the outside.

[0012] Preferably, the needle handle and the push block are connected by a matching elastic buckle.

[0013] With the above settings, after the piston cylinder is pushed to the top of the needle handle, the elastic buckles can engage with each other, thereby ensuring that the piston cylinder can be stably positioned at the top of the needle handle.

[0014] Preferably, the front end sidewall of the needle is provided with several through grooves that communicate with the internal channels of the needle.

[0015] The above setup allows internal anesthetic drugs to be injected from multiple points, thereby improving the injection effect.

[0016] Preferably, the volume of the first drug cavity is equal to the volume of the second drug cavity.

[0017] The above settings ensure that the amount of medication injected in the first injection is equal to the amount injected in subsequent continuous injections. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figures 1-4As shown, a rapid sedation and analgesia treatment needle includes a needle head 1 and a needle handle 2. The needle head 1 is a hollow tube and an elastic needle. A sealing membrane 11 is connected inside the needle head 1. Several through grooves 12 are provided on the side wall of the opening at the front end of the needle head 1, and the through grooves 12 communicate with the internal channel of the needle head 1. The tail end of the needle head 1 communicates with the first drug chamber 4 inside the needle handle 2. A piston cylinder 3 is slidably fitted inside the first drug chamber 4. The piston cylinder 3 contains a second drug chamber 5. An opening 31 is provided at the front end of the piston cylinder 3, and the diameter of the opening 31 is... With the same diameter as the needle 1 channel, the volume of the first drug chamber 4 is equal to the volume of the second drug chamber 5. The piston cylinder 3 has several through holes 34 at its rear end. The rear end of the piston cylinder 3 is a high-pressure chamber 6, which contains high-pressure gas. The needle handle 2 has several sealing rods 21 connected to the through holes 34 at its inner end. The sealing rods 21 pass through the through holes 34. The piston cylinder 3 has a control rod 32 connected to its rear end. The control rod 32 passes through the outside of the needle handle 2 and is connected to a push block 33. The push block 33 and the rear end of the needle handle 2 are fitted with an elastic buckle 6.

[0025] The specific implementation process is as follows: First, it is necessary to determine the injury condition of the patient and determine the location for needle implantation based on the injury condition. Hold the needle handle 2 and insert the needle tip 1 into the corresponding position. Slowly push the needle handle 2 until the needle tip 1 protrudes about 2mm from the skin. Then press down on the push block 33, and the piston cylinder 3 moves forward. The anesthetic drug in the first drug chamber 4 breaks through the sealing membrane and is injected into the body from the front end of the needle tip 1. After the piston cylinder 3 reaches the front end of the needle handle 2, the elastic buckle 7 on the push block 33 at the tail end locks with the elastic buckle 7 on the needle handle 2, and all the drug in the first drug chamber 4 is injected. At this time, the sealing rod 21 is dislodged from the through hole 34. The through hole 34 connects the high pressure chamber 6 and the second drug chamber 5. Under the combined action of gravity and air pressure, the anesthetic drug in the second drug chamber 5 slowly flows out to provide continuous analgesia, similar to a slow-release injection. Then, use paper tape to fix the injection needle to ensure continuous analgesia.
