DETAILED DESCRIPTION
[0014] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.
[0015] Example: A medical gas collection bag
[0016] like Figure 1 - As shown in Figure 2, a medical gas collection bag, the specific structure of which includes:
[0017] The bag body 1 has a connecting pipe 2 integrally fixedly installed on the top of the bag body 1, a threaded interface 3 is fixedly installed on the upper end of the connecting pipe 2, a sealing cover 4 is threadedly installed on the threaded interface 3, and a movable sealing component is provided in the middle of the connecting pipe 2, which can control the opening and closing of the connecting pipe 2.
[0018] The sealing assembly includes a sealing block 5, a first through hole 6 is opened on one side of the connecting pipe 2, a transverse groove 7 coaxial with the first through hole 6 is opened on one side of the sealing block 5, the transverse groove 7 is communicated with the first through hole 6, and the first through hole 6 is movably installed with an insertion rod 8, the inner end of the insertion rod 8 is fixedly installed with one end of a connecting spring 9, and the other end of the spring 9 is fixedly connected to the side opposite to the inner wall of the transverse groove 7, the top and bottom surfaces of the transverse groove 7 are both provided with a third through hole 10, and the top of the insertion rod 8 is provided with a fourth through hole 11 that can be opposite to the third through hole 10. When the patient's exhaled gas needs to be collected, the rod 8 is pressed into the transverse groove 7 and the rod 8 is moved so that the fourth through hole 11 and the corresponding third through hole 10 are in a relative state. At this time, the patient's exhaled gas can pass through the third through hole 10 located above, the fourth through hole 11, and the third through hole 10 located below along the connecting tube 2 into the bag body 1 for collection. At this time, the spring 9 is compressed. When the exhalation is completed, the rod 8 is released. At this time, the rod 8 moves in the opposite direction under the action of the elastic force of the spring 9 to reset, so that the fourth through hole 11 and the third through hole 10 are in a misaligned state again, thereby realizing the sealing of the connecting tube 2. This can prevent external air from entering the bag body 1 when the patient installs the sealing cover 4, thereby improving the sampling accuracy of the gas sample.
[0019] A sealing ring 12 is fixedly mounted within the first through hole 6 and is fitted around the outer periphery of the insertion rod 8. The inner wall of the sealing ring 12 is in close contact with the outer periphery of the insertion rod 8. This structural design improves the sealing between the insertion rod 8 and the first through hole 6, preventing external air from entering the bag body 1 through the gap between the insertion rod 8 and the first through hole 6, and also prevents gas leakage within the bag body 1, further improving the performance of the device.
[0020] The outer end of the insertion rod 8 is fixedly mounted with a pressing plate 13. The pressing plate 13 can increase the contact area between the end of the insertion rod 8 and the user's fingers, thereby improving the comfort of the user when pressing the pressing plate 13.
[0021] Limiting plates 14 are fixedly mounted on the top and bottom of the outer section of the connecting tube 2. When the limiting plates 14 contact the outer side of the connecting tube 2, the fourth through hole 11 and the two third through holes 10 are aligned, thereby keeping the connecting tube 2 unobstructed. The limiting plates 14 facilitate positioning of the third through holes 10, making it easier to use.
[0022] Working principle:
[0023] When the device is in use, the interior of the bag body 1 is in a vacuum state. After rotating the sealing cover 2, the patient blows air into the bag body 1 through the threaded interface 3 and the connecting tube 2. When blowing, the sealing component is opened. At this time, the gas exhaled by the patient can enter the bag body 1 for storage and collection. After the gas sample is collected, the connecting tube 2 is sealed again through the sealing component. At this time, external air can be prevented from entering the bag body 1, thereby improving the sample collection effect of the device.
