Description

Technical Field

[0001] This invention relates to the field of field equipment, and more particularly to a button-type automatic analgesia device. Background Technology

[0002] In field conditions, individual soldiers inevitably encounter gunfire during combat. The intense pain caused by the wounds affects their ability to save themselves, and in severe cases, it can even lead to fainting and shock.

[0003] Existing battlefield analgesia devices generally consist of syringes containing analgesics, oral analgesics, or topical analgesics. Using syringes requires certain clinical medical skills and is time-consuming, preventing wounded soldiers from receiving immediate and effective pain intervention and self-help. Oral analgesics have a slow onset of action and cannot quickly relieve pain. Topical analgesics only provide temporary pain relief to the skin near the application site, which is unsuitable given the typically severe injuries sustained on the battlefield. Therefore, existing analgesia devices generally suffer from poor portability, time-consuming operation, and unsatisfactory analgesic effects. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a button-type automatic analgesia device, which has a simple structure, small size, good portability, and can automatically release analgesics to achieve continuous analgesia.

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

[0006] A button-type automatic analgesia device includes a hollow shell, a first sealing element, a second sealing element, and an analgesic drug and an elastic memory sheet disposed within the shell. The shell consists of an upper shell and a lower shell that are interconnected. The elastic memory sheet divides the inner cavity of the upper shell into a first cavity and a second cavity. The first cavity is a negative pressure cavity. The upper shell has an air inlet that connects to the first cavity. The first sealing element is disposed on the air inlet. The lower shell has a third cavity that connects to the second cavity and is filled with the analgesic drug. The lower shell has a drug outlet that connects to the third cavity. The second sealing element is disposed on the drug outlet.

[0007] More preferably, the button-type automatic analgesia device of the present invention further includes an elastic telescopic member, which is disposed in the first cavity and located between the elastic memory sheet and the upper shell, and the elastic telescopic member is in a pre-tightened state.

[0008] More preferably, the upper housing is partially spherical, the first sealing element is a fan-shaped sphere with a rotating shaft at the top and a protruding strip at the bottom edge, the top of the upper housing has a groove for accommodating the rotating shaft, and the bottom circumferentially has a sliding groove for accommodating the protruding strip, the first sealing element is sealed to the upper housing and the upper housing can rotate circumferentially.

[0009] More preferably, the number of air inlets is 1 to 4, and each air inlet is distributed circumferentially along the upper housing.

[0010] More preferably, the lower bottom surface of the upper housing is provided with an adhesive layer, and release paper is provided on the adhesive layer.

[0011] More preferably, the lower housing is a needle tube with a needle tip.

[0012] More preferably, the second seal is a sealing sleeve, which is fitted onto the lower housing and the opening of the second seal is sealed to the housing.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention provides a button-type automatic analgesia device that enables the injured person to quickly apply the analgesia device to the wound site independently, and automatically releases analgesic drugs to achieve a continuous analgesic effect.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] Please see Figure 1 A button-type automatic analgesic device includes a hollow shell 10, a first sealing element 20, a second sealing element 30, and an analgesic drug 40 and an elastic memory sheet 50 disposed within the shell 10. The shell 10 is composed of an upper shell 11 and a lower shell 12 that are interconnected. The elastic memory sheet 50 divides the inner cavity 60 of the upper shell 11 into a first cavity 61 and a second cavity 62. The first cavity 61 is a negative pressure cavity. The upper shell 11 is provided with an air inlet 13 that is connected to the first cavity 61. The first sealing element 20 is provided on the air inlet 13. The lower shell 12 is provided with a third cavity 70. The second cavity 62 and the third cavity 70 are connected and the cavity is filled with the analgesic drug 40. The lower shell 12 is provided with a drug outlet 14 that is connected to the third cavity 70. The drug outlet 14 is provided with a second sealing element 30.

[0024] Preferably, the bottom diameter of the upper housing 11 is 20 mm, and the diameter of the air inlet 13 is 0.4 mm. The length of the lower housing 12 is 6 mm, and the diameter of the medicine outlet 14 on the lower housing 12 is 0.5 mm.

[0025] The analgesic device described in the above embodiments is simple in structure, small in size, and has excellent portability. Please refer to... Figure 2 Simultaneously, during use, simply remove the second seal 30, insert the lower housing 12 into the wound, and then remove the first seal 20. Atmospheric pressure enters the negative pressure chamber through the air inlet 13. As the negative pressure decreases, the elastic memory sheet 50 gradually returns to its initial shape. During this return process, it pushes the analgesic drug 40 within the second chamber 62, causing it to be released outward through the drug outlet 14, thereby achieving a rapid analgesic effect. At the same time, the recovery process of the elastic memory sheet 50 allows for a slow release of the drug, prolonging the duration of pain relief.

[0026] Preferably, the analgesic device further includes an elastic telescopic member 80, which is disposed within the first cavity 61 and located between the elastic memory sheet 50 and the upper housing 11. The elastic telescopic member 80 is in a pre-tightened state. The elastic telescopic member 80 can be a spring, and its elastic force does not need to be large. When the first seal 20 is opened, airflow enters the first cavity 61 through the air inlet 13, reducing the negative pressure within the first cavity 61. Since the air inlet 13 is small, the negative pressure decreases slowly. At this time, the elastic telescopic member 80 returns to its original position, providing a boosting force to the elastic memory sheet 50, causing the elastic memory sheet 50 to quickly begin to return to its original position. The analgesic drug 40 enters the wound instantly, resulting in rapid analgesia.

[0027] The upper housing 11 is partially spherical, and the first sealing member 20 is a fan-shaped spherical surface with a rotating shaft 21 at its top and a protruding strip 23 at its bottom edge. The upper housing 11 has a groove 15 at its top to accommodate the rotating shaft 21 and a sliding groove 16 at its bottom circumferentially to accommodate the protruding strip 23. The first sealing member 20 is sealed to the upper housing 11 and rotates circumferentially around the upper housing 11. The sealing connection can be achieved by providing a sealing strip (not shown) around the first sealing member 20. The number of air inlets 13 is 1 to 4, and each air inlet 13 is distributed circumferentially around the upper housing 11. Figure 3 As shown, four air inlets 13 are provided. Through the first seal 20 that moves around the circumference and the circumferentially distributed air inlets 13, the first seal 20 can be used as an air intake speed adjustment knob. By opening the air inlets 13 one by one, the injured person can selectively control the speed of analgesic administration according to the degree of pain.

[0028] Preferably, the lower bottom surface of the upper housing 11 is provided with an adhesive layer 90, and release paper (not shown) is provided on the adhesive layer 90. The adhesive layer 90 allows the analgesic device to be easily fixed at the wound site, freeing up the hands and preventing the patient's limb mobility from being affected by pain relief.

[0029] The lower housing 12 is a needle tube with a needle tip, which allows the injured person to quickly insert the analgesia device into the wound and reduces the pain when the device is inserted.

[0030] The second sealing element 30 is a sealing sleeve, which is fitted onto the lower housing 12 and its opening is sealed to the housing 10. Alternatively, the second sealing element 30 is a sealing membrane (not shown), which is sealed to each of the drug outlets 14. Both the sealing sleeve and the sealing membrane have the advantages of quickly opening the drug outlets 14 and are easy to operate.

[0031] When the second seal 30 is not opened, there is no gap between the upper housing 11 and the air inlet 13, so gas cannot enter. The elastic memory sheet 50 is in a pressurized state. After the upper housing 11 is opened, gas enters through the air inlet 13, and the elastic memory sheet 50 will slowly return to a flat state.

[0032] The analgesic drug 40 is preferably ropivacaine lactate glycolic acid copolymer nanoparticles.

[0033] Please see Figures 1 to 3 The working principle of the button-type automatic analgesia device of the present invention is as follows:

[0034] Step 1: Before using the analgesic device, the elastic telescopic part 80 cannot extend because it is in the negative pressure chamber;

[0035] Step 2: When using, first remove the release paper from the second sealing member 30 that is fitted on the outside of the lower housing 12 and the adhesive layer 90 on the bottom surface of the upper housing 11;

[0036] Step 3: Insert the lower shell 12 vertically into the chest wall along the upper edge of the wound about 1 cm away, and fix it to the chest wall skin by means of the adhesive layer 90;

[0037] Step 4: Rotate the first seal 20 to open the air inlet 13;

[0038] Step 5: At this time, the first cavity 61 is connected to the atmosphere through the tiny air inlet 13. The isolated analgesic drug 40 and the elastic memory sheet 50 in the second cavity 62 are gradually restored under the push of the elastic telescopic component 80, and at the same time, the analgesic drug 40 is pushed into the human body.

[0039] Step 6: Rotate the first seal 20. When there are 4 air inlets 13, the air intake speed is divided into 4 levels. Each level has one more air inlet 13, so the air intake speed becomes faster and faster. The rebound speed of the elastic telescopic component 80 is correspondingly faster, and the final injection speed is also faster.

[0040] This invention discloses a button-type automatic analgesia device that allows wounded soldiers to quickly and independently apply the device to the wound site, automatically releasing analgesics for sustained pain relief. Furthermore, the invention utilizes the interaction of a circumferentially moving first seal 20 and circumferentially distributed air inlets 13. The first seal 20 can act as an air intake speed adjustment knob, allowing the wounded soldier to selectively control the rate of analgesic delivery based on the severity of pain by opening each air inlet 13. Simultaneously, this invention is easy to operate, has a simple structure, and is small in size, offering excellent portability. It can be applied to self-rescue and mutual aid for chest trauma analgesia in frontline personnel, effectively preventing neurogenic shock or respiratory and circulatory disorders caused by severe chest trauma pain, thereby reducing mortality, increasing survival rates, and improving prognosis and quality of life.
