Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fumigation nozzle and a traditional Chinese medicine fumigation device. Background Technology

[0002] Traditional Chinese medicine fumigation combines the functions of traditional Chinese medicine treatment, heat therapy, gas therapy, and traditional Chinese medicine ion penetration therapy. Depending on the patient's condition, the type of traditional Chinese medicine and the dosage of the medicinal solution can be selected. The medicinal solution is heated by a heating container to generate traditional Chinese medicine steam, which is applied directly to the surface of the patient's skin. This causes the pores on the skin surface to dilate, which not only promotes blood circulation and unblocks the meridians, but also helps the absorption of the medicine, achieving a deep therapeutic effect.

[0003] However, existing fumigation therapy devices produce a lot of bubbles when decocting certain medicines (those with high sugar and amino acid content). At the start of steam spraying, the nozzle continuously sprays water droplets for about 10 seconds. During treatment, the distance between the nozzle and the patient's treatment area usually relies on the experience of medical staff, making it difficult to ensure the optimal distance. This results in generally poor treatment effectiveness, and improper operation by medical staff can cause patient panic and even burns. Utility Model Content

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0035] This utility model proposes a fumigation nozzle.

[0036] Reference Figures 1 to 3 In one embodiment of this utility model, the fumigation nozzle includes a nozzle housing 10, a gas pipeline 20, a temperature measuring device 30, and a distance measuring device 40; the nozzle housing 10 has an air outlet 10a; the gas pipeline 20 has an inlet end and an outlet end, the inlet end of the gas pipeline 20 is adapted to be connected to an external steam generator, and the outlet end of the gas pipeline 20 is located at the outlet 10a; the temperature measuring device 30 is located inside the nozzle housing 10 and is used to detect the surface temperature of the target fumigation area; the distance measuring device 40 is located inside the nozzle housing 10 and is used to measure the distance between the fumigation nozzle and the target fumigation area.

[0037] In this embodiment, the gas pipeline 20 may include an inlet pipe 21 and an outlet pipe 22. The outlet end of the outlet pipe 22 may be equipped with a hinged outlet head, which enables adjustment of the outlet angle. Preferably, the adjustable range of the outlet angle can be set to ±30°, but this is not limited.

[0038] In this embodiment, the temperature measuring device 30 may be an infrared temperature sensor or other non-contact temperature sensor 50, which is not limited here.

[0039] In this embodiment, the ranging device 40 may be an infrared ranging device or an ultrasonic ranging device, etc., and there is no limitation here.

[0040] It is understood that this utility model improves the nozzle structure of the traditional Chinese medicine fumigation equipment, realizes real-time monitoring of the temperature of the target fumigation site and the distance between the fumigation nozzle and the target fumigation site, effectively improves the fumigation treatment effect, and makes the operation more convenient and accurate for medical staff, can prevent burns to patients, and improves the safety of fumigation treatment.

[0041] To facilitate the installation of the temperature measuring device 30 and the distance measuring device 40, and to ensure the ability to measure the temperature and distance of the target fumigation area, refer to Figure 1 and Figure 2 In one embodiment, the nozzle housing 10 may also be provided with a first mounting hole and a second mounting hole. The first mounting hole and the second mounting hole are symmetrically arranged about the center of the air outlet 10a. The temperature measuring device 30 is installed in the first mounting hole and the distance measuring device 40 is installed in the second mounting hole.

[0042] In this embodiment, the temperature measuring device 30 includes an infrared temperature sensor, a first ceramic heat-insulating bracket, and a first electromagnetic shielding cover. The infrared temperature sensor is mounted in a first mounting hole through the first ceramic heat-insulating bracket, and the first electromagnetic shielding cover is placed over the infrared temperature sensor. This allows for real-time monitoring of the patient's fumigation surface temperature, preventing burns. The ceramic heat-insulating bracket also prevents the infrared temperature sensor's performance from being affected by high-temperature steam. Furthermore, the electromagnetic shielding cover helps resist electromagnetic interference and improves the accuracy and stability of temperature measurement.

[0043] Similarly, the ranging device 40 includes an infrared ranging sensor, a second ceramic heat-insulating bracket, and a second electromagnetic shield. The infrared ranging sensor is mounted in a second mounting hole via the second ceramic heat-insulating bracket, and the second electromagnetic shield covers the infrared ranging sensor. This allows for real-time monitoring of the distance between the fumigation nozzle and the fumigation area, enabling the adjustment of the optimal treatment distance for the patient. The ceramic heat-insulating bracket prevents the performance of the infrared ranging sensor from being affected by high-temperature steam. Furthermore, the electromagnetic shield helps resist electromagnetic interference and improves the accuracy and stability of distance measurement.

[0044] In this embodiment, the fumigation nozzle can also be equipped with an alarm. The alarm can be a device that outputs signals such as sound or images. This setting can enable the output of an alarm signal when the temperature of the fumigation area is too high or the distance is too close. By adopting a dual threshold alarm system, safety can be further improved.

[0045] Furthermore, the probe surfaces of both infrared temperature sensors and infrared distance sensors can be covered with a hydrophobic protective film, which can reduce the influence of steam on temperature and distance measurements.

[0046] Reference Figures 1 to 3 In one embodiment, the fumigation nozzle may further include a temperature sensor 50 disposed within the nozzle housing 10 and near the outlet end of the gas pipeline 20. The temperature sensor 50 is used to detect the temperature of the steam output from the outlet end of the gas pipeline 20. The temperature sensor 50 is electrically connected to a main control device, which is disposed within the nozzle housing 10 or within the steam equipment. Thus, by providing the temperature sensor 50, not only can the steam temperature be monitored in real time, but the main control device can also accurately control the steam temperature, which helps improve the treatment effect and avoids scalding the patient.

[0047] To reduce condensation, refer to Figures 1 to 3 In one embodiment, the fumigation nozzle may further include a condensate treatment box 60, with mounting ears on both sides of the condensate treatment box 60. The nozzle housing 10 has two fixing holes 10b, and the two mounting ears are installed one-to-one at the two fixing holes 10b. At least a portion of the gas pipeline 20 passes through the condensate treatment box 60, which is used to heat the gas pipeline 20 to reduce the generation of condensate.

[0048] Main reference Figure 3 In this embodiment, the condensate treatment box 60 may include a box body 61, an electric heating element 62, a corrugated plate 63, a guide channel 64, and a drain pipe 65. Several corrugated plates 63 are disposed inside the box body 61, the electric heating element 62 is disposed on the corrugated plate 63 and is used to heat the corrugated plate 63, the gas pipeline 20 passes through the corrugated plate 63, the guide channel 64 is disposed on the lower side of the box body 61 and communicates with it, and the drain pipe 65 is communicated with the guide channel 64 and is used to discharge condensate.

[0049] The electric heating element 62 can be made of nickel alloy heat-conducting wire, etc. The operation of the electric heating element 62 can be controlled by setting a PID temperature control module inside or outside the nozzle housing 10, which can reduce the generation of condensate water from the source and greatly improve the safety of fumigation therapy.

[0050] Preferably, multiple corrugated plates 63 are arranged horizontally and evenly in the housing 61. Nickel alloy heating wires can be embedded at the crests of the corrugated plates 63. By setting an electric heating element 62, the surface temperature of the corrugated plates 63 can be controlled to be maintained between 60°C and 70°C. Within this temperature range, the generation of condensate can be effectively suppressed and the heat loss of high-temperature steam can be reduced, keeping the steam at the target treatment temperature, which is beneficial to improving the treatment effect. In addition, the guide channel 64 can be V-shaped to facilitate the collection of condensate. The guide channel 64 is provided with through holes to connect to the drain pipe 65.

[0051] In addition, the surface of the corrugated plate 63 can be sprayed with a hydrophobic coating to reduce the adhesion of condensate. The corrugated plate 63 itself has a corrugated structure, which allows condensate to slide down quickly and be guided to the drain pipe 65 by the guide channel 64.

[0052] To facilitate the disassembly and assembly of the nozzle housing and its internal components, and to further improve the structural compactness of the fumigation nozzle, refer to Figure 1 and Figure 2 In one embodiment, the nozzle housing 10 may include a cylinder, a flow guide, a front cover, and a rear cover. The front cover and the rear cover are respectively installed on both ends of the cylinder. The flow guide can be snapped onto the end of the cylinder with the front cover by a buckle 101, and the rear cover can be snapped onto the other end of the cylinder by a slot 102. The air outlet 10a, the first mounting hole, and the second mounting hole are all opened on the front cover.

[0053] In summary, this invention integrates infrared temperature measurement and distance measurement modules, solving the problem that existing fumigation nozzles only detect temperature and cannot dynamically adjust temperature and distance in a coordinated manner. Furthermore, by incorporating electromagnetic shielding, a hydrophobic coating, and a flow-guiding structure, this invention improves the sensor's stability in humid and hot environments, reducing the impact of these environments on sensor accuracy. The dual-threshold alarm system for temperature and distance significantly reduces the risk of burns, making it particularly suitable for patients with temperature perception impairments.

[0054] This utility model also proposes a traditional Chinese medicine fumigation device, which includes a fumigation nozzle. The specific structure of the fumigation nozzle is as described in the above embodiments. Since the traditional Chinese medicine fumigation device proposed in this utility model includes all the solutions of all embodiments of the above-mentioned fumigation nozzle, it has at least the same technical effect as the above-mentioned fumigation nozzle, which will not be described in detail here.

[0055] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
