Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a water collecting device for a ventilator pipeline. Background Art

[0002] During the use of the ventilator, a large amount of condensed water will be generated in the breathing circuit due to the heating and humidification of the inhaled gas. In order to prevent the condensed water from affecting the normal operation of the ventilator, the current method is to set a water collection cup in the middle of the inlet and outlet pipes of the breathing tube to collect the condensed water in the tube.

[0003] However, the ventilator will continuously produce condensed water during long-term use, and the capacity of the water collection cup is limited. Therefore, when the water level in the water collection cup reaches a certain height, it needs to be dumped in time. If the condensed water in the water collection cup is not dumped in time, the condensed water will flow back into the patient's airway, breathing tube or heated humidification device, causing the patient to aspirate, contaminate the heated humidification water, cause or aggravate the patient's lung infection, and affect the function of the ventilator.

[0004] However, the ventilator pipeline water collection cup currently used in clinical practice is a detachable structure. When dumping condensed water, the cup body needs to be disassembled before dumping. For example, a rotating water collection cup for a ventilator pipeline with the announcement number CN210813329U relates to a water collection cup for a ventilator pipeline, comprising a cup body, a cup cover and a "Y"-shaped connecting pipe. The cup cover sealing cover is provided on the cup body, and the first end of the "Y"-shaped connecting pipe is fixedly connected to the cup cover. It is characterized in that the second end and the third end of the "Y"-shaped connecting pipe are respectively sleeved with a first connecting sleeve and a second connecting sleeve that can rotate relatively but cannot slide axially relative to each other, and a sealing ring is respectively provided between the first connecting sleeve and the second connecting sleeve and the second end and the third end of the "Y"-shaped connecting pipe;

[0005] When in use, this patent application requires that the cup body be removed from the cup cover in order to pour out the condensed water in the cup body. However, since condensed water will continuously be generated in the pipeline during the use of the ventilator, medical staff need to repeatedly remove the cup body to pour out the condensed water and then reinstall the cup body on the cup cover, which will bring inconvenience to the medical staff's operation. Utility Model Content

[0006] The embodiment of the present utility model provides a water collection device for a ventilator pipeline to solve the above-mentioned technical problems.

[0007] The embodiment of the utility model adopts the following technical solution: it includes a cup cover and a water collection cup, the water collection cup is arranged below the cup cover, and the water collection cup is transparent. A chamber for collecting condensed water is arranged inside the water collection cup, and the chamber runs through the top and bottom of the water collection cup;

[0008] A circular baffle is provided in the bottom area of ​​the water collecting cup chamber, and the outer wall of the baffle is fixedly connected to the inner wall of the chamber of the water collecting cup.

The outer wall of the baffle is fixedly connected to the inner wall of the baffle ring, and a shielding member that can shield the bottom of the chamber is provided inside the water collecting cup.

[0009] Preferably, the shielding member is a cylindrical structure and its outer diameter is the same as the inner diameter of the annular retaining ring. A drainage groove of the same size as the block is provided on one side of the bottom of the shielding member. When the shielding member is placed in the middle area of ​​the circular ring of the retaining ring and the drainage groove part and the block are kept in a spliced ​​state, the bottom of the chamber of the water collection cup can be just covered.

[0010] Preferably, the outer surface of the shielding member is provided with an ultra-thin coating of silicone material.

[0011] Preferably, a vertical pillar is fixedly provided at the top center of the shielding member, a sleeve is provided on the outside of the pillar, the top of the sleeve is sealed, and the outer wall of the sleeve is fixedly connected to the inner wall of the chamber of the water collecting cup through multiple support members.

[0013] Preferably, the sleeve is provided with a through groove in a vertical track, and a protrusion is fixedly provided on the outer wall of the pillar, and the front end of the protrusion extends into the through groove.

[0014] Preferably, a water baffle is fixedly provided on the bottom of the shielding member along the drainage groove, and a certain gap is provided between the water baffle and the blocking block.

[0015] At least one of the above technical solutions adopted in the embodiment of the present utility model can achieve the following beneficial effects:

[0016] First, compared with the water collection cup used in clinical practice, the present application does not require the water collection cup to be removed from the cup cover when in use. It is only necessary to press the shielding piece upward from the bottom of the water collection cup to create a gap between the shielding piece and the block at the bottom of the water collection cup to allow condensed water to be discharged from the water collection cup. In clinical applications, by pressing the bottom of the water collection cup upward, a simple operation of pressing to drain water can be achieved, which is quick and convenient to operate and can be completed with one hand.

[0017] Secondly, during the operation, you only need to release the pressure control of your hand on the shielding piece, and the shielding piece can be reset under the thrust of the spring, so that the shielding piece is re-connected with the baffle ring and the baffle block, thereby re-blocking the bottom of the chamber of the water collection cup to prevent condensed water from being discharged.

[0029] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0030] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the utility model provides a water collection device for a ventilator pipeline, comprising a cup cover 1 and a water collection cup 2;

[0032] Refer to the attached Figures 1 to 4 As shown, the water collecting cup 2 is arranged below the cup cover 1, and the water collecting cup 2 is transparent. A chamber for collecting condensed water is provided inside the water collecting cup 2. The chamber runs through the top and bottom of the water collecting cup 2. A circular baffle ring 3 is provided at the bottom area of ​​the chamber of the water collecting cup 2. The outer wall of the baffle ring 3 is fixedly connected to the inner wall of the chamber of the water collecting cup 2. A C-shaped baffle 4 is provided on the inner wall of the baffle ring 3. The inner side edge of the top of the baffle 4 is a beveled edge. The outer wall of the baffle 4 is fixedly connected to the inner wall of the baffle ring 3. A shielding member 5 for shielding the bottom of the chamber is provided inside the water collecting cup 2.

[0033] After the water collecting cup 2 is installed at the bottom of the cup cover 1, it can cooperate with the cup cover 1 to collect the condensed water in the pipeline. During use, the liquid level of the internal condensed water can be observed through the transparent water collecting cup 2. When the liquid level is too high and the condensed water needs to be dumped, a medical collection container such as a waste liquid collection bucket can be used to place it under the water collecting cup 2, and then the water collecting cup 2 is held and the shielding part 5 is pressed upward from the bottom of the water collecting cup 2, so that the shielding part 5 moves upward in the water collecting cup 2 and creates a gap between the retaining ring 3 and the block 4, so that the condensed water in the water collecting cup 2 can be discharged into the waste liquid collection bucket through the gap.

[0034] In a further preferred embodiment, referring to the attached Figures 3 to 6 As shown, the shielding member 5 is a cylindrical structure and its outer diameter is the same as the inner diameter of the annular retaining ring 3. A drainage groove 6 of the same size as the block 4 is provided on one side of the bottom of the shielding member 5. When the shielding member 5 is placed in the middle area of ​​the circular ring of the retaining ring 3 and the drainage groove 6 is kept in a spliced ​​state with the block 4, the bottom of the chamber of the water collection cup 2 can be shielded. The outer surface of the shielding member 5 is provided with an ultra-thin coating of silicone material.

[0035] Under normal conditions, the shielding member 5 is located in the middle area of ​​the circular ring of the retaining ring 3, and the drainage groove 6 area on the shielding member 5 covers the stopper 4. At this time, the shielding member 5, the retaining ring 3 and the stopper 4 are spliced ​​together to form a cylindrical block that can block the bottom of the chamber of the water collection cup 2. The ultra-thin silicone coating provided on the outer surface of the shielding member 5 can increase the sealing performance of the shielding member 5 in contact with the retaining ring 3 and the stopper 4, so that the condensed water in the water collection cup 2 will not be discharged naturally.

[0036] Refer to the attached Figure 7 As shown, when the condensed water needs to be dumped, the shielding member 5 can be pressed upward from the bottom of the water collecting cup 2 to move the shielding member 5 from the middle area of ​​the circular ring of the retaining ring 3 to the top of the retaining ring 3, and the drainage groove 6 on the shielding member 5 that originally covered the stopper 4 will also move upward. At this time, a gap will be generated between the drainage groove 6 of the shielding member 5 and the top and inner wall of the stopper 4 and the inner bevel of the top, and the condensed water in the water collecting cup 2 will be discharged from the gap formed between the drainage groove 6 on the shielding member 5 and the stopper 4;

[0037] Among them, in order to allow the condensed water in the water collecting cup 2 to be discharged smoothly, the top of the shielding member 5 can be gradually lowered from the center to the edge, so that the condensed water can continuously flow along the top area of ​​the shielding member 5 to the gap between the drainage groove 6 and the block 4 under the action of gravity, and then be discharged from the bottom of the water collecting cup 2 to the waste liquid collection bucket, thereby completing the dumping operation of the condensed water in the water collecting cup 2.

[0038] In a further preferred embodiment, referring to the attached Figures 5 to 7 As shown, a vertical pillar 7 is fixedly provided at the top center of the shielding member 5, and a sleeve 8 is sleeved on the outside of the pillar 7. The top of the sleeve 8 is sealed, and the outer wall of the sleeve 8 is fixedly connected to the inner wall of the chamber of the water collecting cup 2 through a plurality of support members 9;

[0039] When the shielding member 5 is pressed upward, the support 7 on the top of the shielding member 5 will move upward in the sleeve 8, and under the guidance of the sleeve 8, the support 7 and the shielding member 5 can avoid tilting when being pressed, thereby preventing the shielding member 5 from being unable to move upward normally in the water collecting cup 2 due to tilt.

[0040] In a further preferred embodiment, referring to the attached Figure 8 As shown, a spring 10 is provided between the interior of the sleeve 8 and the top of the support 7. Under the thrust of both ends of the spring 10, the support 7 can be pushed downward in the sleeve 8.

[0041] After the condensed water in the water collecting cup 2 is discharged, the pressing operation on the shielding member 5 can be released immediately. Under the thrust of the spring 10, the support 7 will move downward in the sleeve 8 and drive the shielding member 5 down, so that the shielding member 5 is re-connected with the retaining ring 3 and the block 4, thereby re-blocking the bottom of the chamber of the water collecting cup 2 to prevent the condensed water from being discharged.

[0042] In a further preferred embodiment, referring to the attached Figure 5 and 8 As shown, the sleeve 8 is provided with a through groove 11 in a vertical track, and a protrusion 12 is fixedly provided on the outer wall of the support 7, and the front end of the protrusion 12 extends into the through groove 11;

[0043] The through slot 11 is provided to limit the up and down movement distance of the protrusion 12 on the pillar 7, thereby constraining the movable distance of the pillar 7 in the sleeve 8, so that the shielding member 5 at the bottom of the pillar 7 will not be unable to reset normally due to movement overload.

[0044] In a further preferred embodiment, referring to the attached Figure 2 and 5 As shown, a water baffle 13 is fixedly provided at the bottom of the shielding member 5 along the drainage groove 6, and there is a certain gap between the water baffle 13 and the block 4;

[0045] The water baffle 13 provided at the bottom of the shielding member 5 can cooperate with the block 4 to guide the discharge of condensed water.

[0046] In a further preferred embodiment, referring to the attached Figure 7 and 8 As shown, the bottom of the cup cover 1 can be sleeved on the outside of the edge of the water collection cup 2. The water collection cup 2 is provided with a thread near the outer wall of the edge, and the inner wall portion of the bottom of the cup cover 1 that can contact the water collection cup 2 is provided with a thread groove that matches the thread.

[0047] By setting the threads on the outer wall along the mouth of the water collecting cup 2 and the threaded grooves on the inner wall at the bottom of the cup cover 1, the water collecting cup 2 can be connected to the cup cover 1 in a convenient installation manner through threaded matching.

[0048] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
