Description

Technical Field

[0001] This utility model relates to the field of handheld therapeutic gun technology, and in particular to a handheld therapeutic gun for a low-temperature shock analgesia device. Background Technology

[0002] Postoperative pain is a response of the body to surgical injury (tissue damage), encompassing a series of physiological, psychological, and behavioral reactions. Low-temperature shock analgesia is a medical research instrument used in basic and clinical medicine to assist in the treatment and relief of swelling and pain caused by acute soft tissue injuries. The treatment gun sprays dry ice directly onto the human body surface, rapidly lowering the skin temperature to achieve a therapeutic effect. It also promotes vasoconstriction, reducing local inflammatory exudation and swelling, and alleviating discomfort.

[0003] However, in existing technologies, handheld therapeutic guns typically use flow valves to control the flow rate of liquid carbon dioxide. When the flow valve malfunctions, the rapid ejection of cooling gas can generate a strong impact force on the patient. When the cooling gas rapidly impacts the skin, the patient will feel significant stinging or discomfort. This sensation can cause tension and fear in the patient, reducing their acceptance of the treatment. Therefore, a handheld therapeutic gun for low-temperature shock analgesia has been proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that when the cooling gas rapidly impacts the skin, the patient will feel obvious stinging or discomfort, which will cause the patient to feel tense, fear and other emotions, and reduce the patient's acceptance of the treatment. Therefore, a handheld treatment gun for low temperature impact analgesia is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a handheld therapeutic gun for a low-temperature shock analgesia device, comprising a housing and a flow valve, wherein a flow cavity is provided inside the housing, a square groove is provided inside the flow cavity, and a flow control mechanism is provided inside the square groove;

[0006] The flow control mechanism includes a square frame and a first guide plate. One end of the square groove has a placement slot. An annular square plate is fixedly installed on the inner side wall of the square groove. Four sets of support springs are provided at one end of the annular square plate. A second guide plate is fixedly installed inside the square frame. Multiple sets of horizontal elliptical holes are opened through one end of the second guide plate. A vertical elliptical hole is opened through one end of the first guide plate. One end of the first guide plate is fixed to one end of the square groove. The other ends of the four sets of support springs are all fixed to one end of the second guide plate.

[0007] Preferably, a guide tube is fixedly installed at one end of the annular square plate and near the four corners, and one end of each of the four sets of support springs is inserted into the inside of the guide tube.

[0008] Preferably, a hand grip is fixedly installed at the lower end of the outer shell, and a connecting tube is installed through the lower end of the hand grip.

[0009] Preferably, one end of each of the four sets of support springs is fixed to one end of the annular square plate.

[0010] Preferably, a switch assembly is installed through the outer wall of the hand grip, and the upper end of the connecting tube penetrates the outer wall of the outer shell and communicates with the flow cavity.

[0011] Preferably, an arc-shaped blocking bracket is fixedly installed on the outer wall of the hand grip, and a portion of the switch assembly is inserted into the interior of the connecting tube.

[0012] Preferably, the upper end of the arc-shaped blocking frame is fixed to the outer wall of the housing, and one end of the flow valve is fixed to one end of the housing.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, a flow control mechanism is provided to control the flow diameter of the cooling gas, ensuring that the cooling gas can only flow through the gaps created. This prevents the cooling gas from impacting the patient, avoiding significant stinging or discomfort, and minimizing its impact on the patient's mood, thus improving the patient's acceptance of the treatment. Secondly, under the elastic force of four sets of support springs, the four sets of support springs will push the frame to move. The frame will then drive the second guide plate to move inside the square groove, allowing the second guide plate to separate from the first guide plate. This facilitates the flow of cooling gas within multiple sets of horizontal and vertical elliptical holes, making treatment of the patient easier. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a handheld therapeutic gun for a low-temperature shock analgesia device, including a housing 12 and a flow valve 13. The housing 12 has a flow cavity 16 inside, the flow cavity 16 has a square groove 17 inside, and the square groove 17 is provided with a flow control mechanism 2.

[0023] The flow control mechanism 2 includes a frame 21 and a first guide plate 22. A placement slot 23 is provided at one end of a square groove 17. An annular square plate 24 is fixedly installed on the inner sidewall of the square groove 17. Four sets of support springs 26 are provided at one end of the annular square plate 24. A second guide plate 27 is fixedly installed inside the frame 21. Multiple sets of horizontal elliptical holes 28 are provided through one end of the second guide plate 27. A vertical elliptical hole 29 is provided through one end of the first guide plate 22. One end of the first guide plate 22 is fixed to one end of the square groove 17, and the other ends of the four sets of support springs 26 are all fixed to... One end of the second guide plate 27 is fixed, a hand grip 1 is fixedly installed at the lower end of the outer shell 12, a connecting pipe 11 is installed through the lower end of the hand grip 1, a switch assembly 14 is installed through the outer wall of the hand grip 1, the upper end of the connecting pipe 11 is connected to the flow cavity 16 through the outer wall of the outer shell 12, an arc-shaped blocking frame 15 is fixedly installed on the outer wall of the hand grip 1, a part of the switch assembly 14 is inserted into the inside of the connecting pipe 11, the upper end of the arc-shaped blocking frame 15 is fixed to the outer wall of the outer shell 12, and one end of the flow valve 13 is fixed to one end of the outer shell 12.

[0024] The specific settings and functions of this embodiment are described in detail below. When subjected to a strong impact, the cooling gas will impact the frame 21. The frame 21 will push the four sets of support springs 26 to move, causing the four sets of support springs 26 to be compressed inside the four sets of guide cylinders 25 respectively. At the same time, the frame 21 will also drive the second guide plate 27 to move until the second guide plate 27 contacts the first guide plate 22. At this time, gaps will be generated between the multiple sets of horizontal elliptical holes 28 and the multiple sets of vertical elliptical holes 29. Part of the multiple sets of horizontal elliptical holes 28 will be blocked by the surface of the first guide plate 22, and the multiple sets of vertical elliptical holes 29 will be blocked by the surface of the second guide plate 27. In this way, the flow diameter of the cooling gas can be controlled, so that the cooling gas can only flow from the gaps generated. This can prevent the cooling gas from impacting the patient, prevent the patient from feeling obvious stinging or discomfort, and will not affect the patient's mood, thereby improving the patient's acceptance of the treatment.

[0025] Under the elastic force of the four sets of support springs 26, the four sets of support springs 26 will push the frame 21 to move, and the frame 21 will drive the second guide plate 27 to move inside the square groove 17, which can separate the second guide plate 27 from the first guide plate 22, so that the cooling gas can flow inside the multiple sets of horizontal elliptical holes 28 and multiple sets of vertical elliptical holes 29, which is convenient for treating patients.

[0026] The four sets of guide cylinders 25 can guide the four sets of support springs 26 and prevent the four sets of support springs 26 from shifting when they are compressed.

[0027] The switch assembly 14 controls whether the connecting pipe 11 flows with refrigerant gas, the flow chamber 16 facilitates the flow of refrigerant gas within it, and the flow valve 13 further controls the flow rate of the refrigerant gas.

[0028] Example 2: Figure 1 and Figure 2 As shown, one end of the annular square plate 24 is provided with four sets of support springs 26, and guide cylinders 25 are fixedly installed at one end of the annular square plate 24 and near the four corners. One end of each of the four sets of support springs 26 is inserted into the inside of the guide cylinders 25, and one end of each of the four sets of support springs 26 is fixed to one end of the annular square plate 24.

[0029] The overall effect of this embodiment is that by installing a hand grip 1 at the lower end of the housing 12, it is convenient for staff to hold the device to treat patients, while the arc-shaped blocking frame 15 can block the staff's hands.

[0030] The usage and working principle of this device are as follows: First, connect one end of the connecting pipe 11 to the folded pipe of the external high-pressure gas therapy device. The external high-pressure gas therapy device then inputs cooling gas into the connecting pipe 11. The cooling gas enters the flow chamber 16 through the connecting pipe 11. Finally, when the impact force generated by the flowing cooling gas is strong, the cooling gas impacts the frame 21. The frame 21 pushes the four sets of support springs 26 to move, causing the four sets of support springs 26 to compress inside the four sets of guide cylinders 25. Simultaneously, the frame 21 also drives the second guide plate 27. Move until the second guide plate 27 contacts the first guide plate 22. At this time, gaps will be generated between the multiple sets of horizontal elliptical holes 28 and the multiple sets of vertical elliptical holes 29. Part of the multiple sets of horizontal elliptical holes 28 will be blocked by the surface of the first guide plate 22, and the multiple sets of vertical elliptical holes 29 will be blocked by the surface of the second guide plate 27. This can control the flow diameter of the cooling gas, prevent the cooling gas from impacting the patient, and allow the cooling gas to flow into the interior of the flow valve 13 through the opening at one end of the outer shell 12 and flow out from the interior of the flow valve 13, which can spray the patient's painful or injured area.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
