Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a medical air compressor condensate collection device. Background Technology
[0002] Medical air guns are primarily used for the manual drying of reusable medical instruments (general instruments, tubular instruments, endoscopic instruments, etc.) after cleaning and disinfection in sterilization supply centers. This process is an essential step and procedure in the handling of reusable medical devices in sterilization supply centers. The operation of a medical air gun requires connection to an air source device (air compressor). The working principle of an air compressor is to draw in ambient air, compress it, and then expel it under high pressure inside the compressor. During operation, the internal temperature of the air compressor is relatively high, which draws in moisture from the ambient air, creating water vapor during operation. Therefore, the drawn-in ambient air needs to be cooled before it can be used. When compressed air passes through cooling equipment, water vapor condenses upon cooling, accumulating in the air pipeline. This condensate, mixed with grease and solid impurities, is ejected with the compressed air, causing secondary contamination of the cleaned and disinfected instruments. Therefore, condensate needs to be drained periodically based on usage frequency. However, during condensate drainage, due to air pressure, the air compressor's storage tank may splash out when the valve is opened, even spraying into the eyes and faces of medical personnel, contaminating their bodies and the working environment. Utility Model Content
[0003] To address the aforementioned issues, this application discloses a medical air compressor condensate collection device, which is connected to the drain valve of the air compressor's storage tank during use. This prevents the condensate from splashing due to air pressure when draining the air compressor's storage tank, thus protecting medical personnel and preventing pollution of the working environment.
[0004] To achieve the above objectives, this application adopts the following technical solution:
[0005] A collection container includes a top layer and a bottom layer opposite to each other, and an elastic sleeve, wherein the elastic sleeve is located between the top layer and the bottom layer and connects the top layer and the bottom layer, such that a receiving chamber is formed between the top layer, the bottom layer and the elastic sleeve, wherein the top layer is provided with an inlet pipe and an outlet pipe communicating with the receiving chamber, and the receiving chamber flows unidirectionally into the outlet pipe;
[0006] A connecting pipe having a first connecting end and a second connecting end, wherein the first connecting end is sealed to the access pipe;
[0007] The top layer of the collection container can move closer to the bottom layer to compress the elastic sleeve, allowing air in the receiving chamber to be discharged through the discharge pipe.
[0008] In one illustrative embodiment of a medical air compressor condensate collection device, the outer wall of the elastic sleeve has a corrugated structure.
[0009] In one illustrative embodiment of a medical air compressor condensate collection device, a spring is provided in the receiving chamber, wherein one end of the spring abuts against the inner surface of the top layer and the other end of the spring abuts against the inner surface of the bottom layer.
[0010] In one illustrative embodiment of a medical air compressor condensate collection device, the first connection end is inserted into the inlet pipe.
[0011] In one illustrative embodiment of a medical air compressor condensate collection device, the medical air compressor condensate collection device further includes: a heat shrink tubing, wherein the heat shrink tubing is sleeved on the outer wall of the first connecting end and the inlet pipe.
[0012] In one illustrative embodiment of a medical air compressor condensate collection device, the elastic sleeve is made of either rubber or silicone.
[0013] In one illustrative embodiment of a medical air compressor condensate collection device, a one-way valve is provided in the discharge pipe, wherein the one-way valve is configured to allow unidirectional flow from the receiving chamber to the discharge pipe.
[0014] In one illustrative embodiment of a medical air compressor condensate collection device, the medical air compressor condensate collection device further includes: a suspension rope, both ends of which are connected to the outer surface of the top layer.
[0015] Beneficial effects:
[0016] 1. By setting up a collection container and connecting pipe, during use, the collection container is connected to the drain valve of the air compressor's air tank via the connecting pipe. When force is applied to the top layer, causing it to move towards the bottom layer, the air in the receiving chamber is squeezed out through the discharge pipe. Since the second connection end of the connecting pipe is closed and the receiving chamber flows unidirectionally into the discharge pipe, a negative pressure is generated in the receiving chamber. When the drain valve of the air compressor's air tank is opened, the condensate in the air compressor's air tank enters the receiving chamber under the action of the air pressure in the air tank, thus collecting the condensate. This prevents the condensate from splashing due to air pressure when draining the air compressor's air tank, thereby protecting medical personnel and preventing pollution of the working environment.
[0017] 2. By installing a one-way valve in the discharge pipe, during use, force is applied to the top layer, causing it to move towards the bottom layer. The air in the receiving chamber is compressed, and the one-way valve is opened under the pressure, allowing the air in the receiving chamber to be discharged through the discharge pipe. This compresses the entire collection container. At this time, under the elastic action of the elastic sleeve, the top layer moves away from the bottom layer, creating a negative pressure in the receiving chamber. After the drain valve of the air compressor's air tank is opened, the condensate flows out with the positive pressure gas in the air compressor's air tank. The negative pressure in the receiving chamber can resist the positive pressure gas in the air compressor's air tank, preventing the condensate from splashing out. This reduces the impact on the connecting pipe and also prevents the connecting pipe from separating from the drain valve of the air compressor's air tank.

[0029] To provide a clearer understanding of the technical features, objectives, and effects of this application, specific embodiments of this application are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0032] Figure 1 This is a schematic diagram showing the connection between the medical air compressor condensate collection device provided in this application and the drain valve 31 of the air compressor storage tank 3; Figure 2 This is a schematic diagram of the overall structure of the medical air compressor condensate collection device provided in this application.
[0033] Combination Figures 1 to 2 The medical air compressor condensate collection device provided in this application includes: a collection container 1 and a connecting pipe 2; (Reference) Figure 1 , Figure 2 , Figure 3 , Figure 4 The collection container 1 includes a top layer 11, a bottom layer 12, and an elastic sleeve 13. The elastic sleeve 13 is located between the top layer 11 and the bottom layer 12, forming a receiving chamber 14 between the top layer 11, the bottom layer 12, and the elastic sleeve 13. The top layer 11 is provided with an inlet pipe 15 and an outlet pipe 16 that communicate with the receiving chamber 14. When the top layer 11 can move closer to the bottom layer 12, for example, by applying force to the top layer 11, the elastic sleeve 13 is deformed, so that the top layer 11 moves closer to the bottom layer 12. At this time, the area of the receiving chamber 14 is compressed, so that the air in the receiving chamber 14 is discharged through the outlet pipe 16.
[0034] The connecting pipe 2 is used to connect the collecting container 1 to the drain valve 31 of the air compressor's air tank 3. The connecting pipe 2 has a first connecting end 21 and a second connecting end 22. The first connecting end 21 is sealed to the inlet pipe 15. For explanation, when the drain valve 31 of the air compressor's air tank 3 is not open, the second connecting end 22 of the connecting pipe 2 is closed. At this time, refer to... Figure 5 When force is applied to the top layer 11, causing it to move closer to the bottom layer 12, the air in the receiving chamber 14 is squeezed out through the discharge pipe 16. Since the second connection end 22 of the connecting pipe 2 is closed and the receiving chamber 14 flows unidirectionally into the discharge pipe 16, a negative pressure is generated in the receiving chamber 14. When the drain valve 31 of the air compressor storage tank 3 is opened, the condensate in the air compressor storage tank 3 enters the receiving chamber 14 under the action of the air pressure in the storage tank, thereby collecting the condensate. At the same time, due to the existence of the negative pressure in the receiving chamber 14, the condensate remaining at the port of the drain valve 31 and the condensate remaining in the connecting pipe 2 can also be drawn into the receiving chamber 14, ensuring that the port of the drain valve 31 and the connecting pipe 2 are clean and dry.
[0035] refer to Figure 1 —3. In a more specific embodiment, the outer wall of the elastic sleeve 13 is corrugated. With this arrangement, the elastic sleeve 13 can have better resilience, so that the cavity 14 can always maintain a stable negative pressure after the elastic sleeve 13 is compressed.
[0036] In a more specific embodiment, the elastic sleeve 13 is made of either rubber or silicone.
[0037] refer to Figure 3 —4. A spring 17 is provided in the receiving chamber 14. One end of the spring 17 abuts against the inner surface of the top layer 11, and the other end of the spring 17 abuts against the inner surface of the bottom layer 12. The outer wall of the spring 17 is in contact with the inner wall of the elastic sleeve 13. In this arrangement, the spring 17 can support the elastic sleeve 13, thereby ensuring that the elastic sleeve 13 can be converted from the compressed state to the original state. In this process, the condensate water remaining at the port of the drain valve 31 and the condensate water remaining in the connecting pipe 2 are drawn into the receiving chamber 14.
[0038] refer to Figures 2 to 3 The first connecting end 21 is inserted into the inlet pipe 15; in a more specific embodiment, the medical air compressor condensate collection device further includes a heat shrink tubing, wherein the heat shrink tubing is sleeved on the outer wall of the first connecting end 21 and the inlet pipe 15; the heat shrink tubing is used to seal the first connecting end 21 and the inlet pipe 15 after they are joined, so as to avoid gas or liquid leakage.
[0039] refer to Figure 4—6. To achieve unidirectional flow from the receiving chamber 14 to the discharge pipe 16, in this example, a one-way valve 161 is installed in the discharge pipe 16. After the connecting pipe 2 connects the collecting container 1 to the drain valve 31 of the air compressor's air tank 3, the receiving chamber 14 is in a closed state under the action of the one-way valve 161. At this time, when force is applied to the top layer 11, causing it to move closer to the bottom layer 12, the air in the receiving chamber 14 is compressed. The one-way valve 161 is opened under the pressure, allowing the air in the receiving chamber 14 to be discharged through the discharge pipe 16, thus making the collecting container 1 in a compressed state. After the force is stopped on the top layer 11, the one-way valve 161 closes, and the receiving chamber 1… 4. The system returns to a sealed state. At this time, under the elastic action of the elastic sleeve 13, the top layer 11 moves away from the bottom layer 12, thereby generating a negative pressure in the receiving chamber 14. Under the action of the negative pressure, the positional relationship between the top layer 11 and the bottom layer 12 will not change, thus maintaining the stability of the negative pressure in the receiving chamber 14. After the drain valve 31 of the air compressor storage tank 3 is opened, the condensate flows out with the positive pressure gas in the air compressor storage tank 3. At this time, the negative pressure in the receiving chamber 14 can resist the positive pressure gas in the air compressor storage tank 3, thus preventing the condensate from splashing out, thereby reducing the impact received by the connecting pipe 2 and preventing the connecting pipe 2 from separating from the drain valve 31 of the air compressor storage tank 3.
[0040] In a more specific embodiment, the volume of the receiving chamber 14 is 200 ml.
[0041] For better placement of the collection container 1, refer to Figure 7 In this example, the medical air compressor condensate collection device further includes a suspension rope 19, wherein both ends of the suspension rope 19 are connected to the outer surface of the top layer 11. In a more specific embodiment, the two ends of the suspension rope 19 are fixed to the outer surface of the top layer 11 by adhesive. In use, the collection container 1 can be suspended to one side of the air compressor by the suspension rope 19, which can prevent medical personnel from kicking the collection container 1 while walking and make the working environment of medical personnel cleaner.
