Description

Technical Field

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

[0002] Ventilators are currently very popular in the process of rescuing and treating patients in hospitals. When a ventilator is in use, in order to prevent the patient's airway from drying out, humidification is required. The working principle of humidification is to heat water to a certain extent with a humidification device to generate a certain amount of water vapor, which enters the patient's airway together with the air supply of the ventilator through the breathing tube, achieving the effect of heating and humidifying. While humidifying the patient, a large amount of condensate water is also generated in the ventilator tube. For the treatment of condensate water, currently, a water collecting cup is installed in the ventilator tube to collect the condensate water.

[0003] However, when the condensate water in the water collecting cup is full, it needs to be poured out. During the pouring process, the tube connected to the water collecting cup will be exposed to the air, which is likely to cause pollution. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a condensate water collecting tank for a ventilator to solve the technical problem in the prior art that the water collecting tank needs to be opened every time the condensate water is poured out, and the tube and the tank are easily exposed and polluted. The preferred technical solutions provided by the utility model can produce many technical effects, which will be elaborated below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A condensate water collecting tank for a ventilator provided by the utility model includes a tank body, a first breathing tube and a second breathing tube. The first breathing tube is fixedly connected to the tank body and is mutually conducted. The second breathing tube is fixedly connected to the tank body and is mutually conducted. A drain pipe is also fixedly connected to the tank body. A drain switch is installed on the drain pipe. The drain switch is a switch shaft. The switch shaft is slidably arranged on the drain pipe along the radial direction of the drain pipe. The circumferential side wall of the switch shaft blocks the inner cavity of the drain pipe. A through hole is opened on the switch shaft. The tank body is made of an elastic and recoverable material. A sealing cover is sleeved on the end of the drain pipe.

[0007] By adopting the above technical solution, during use, the first breathing tube and the second breathing tube are respectively connected to the pipeline of the ventilator, so as to realize the recovery of the redundant water vapor generated in the ventilator pipeline. When the tank is filled with condensed water, rotate the switch shaft to make the condensed water flow out, so as to avoid the situation that the tank pipeline is easily polluted when exposed. And after each drainage, the drain outlet end of the drain pipe is sealed by using the sealing cover, so as to reduce the retention of pollutants. And during the drainage process, the tank body can be squeezed, so that the condensed water in the tank body is quickly discharged from the drain pipe under the action of external pressure.

[0008] Optionally, the connection point between the first breathing tube and the tank body and the connection between the second breathing tube and the tank body are arranged at the same end of the tank body. A plugging component for sealing during drainage is arranged on the tank body, and the plugging component is arranged between the drain switch and the connection point between the first breathing tube and the tank body or the connection point between the second breathing tube and the tank body.

[0009] By adopting the above technical solution, during use, when it is necessary to drain the condensed water inside the tank body, first use the plugging component for sealing, and then open the drain switch to drain the condensed water inside the tank body. During this process, the plugging component will isolate the connection between the first breathing tube and the tank body and the connection between the second breathing tube and the tank body, so as to reduce the pollution of the first breathing tube and the second breathing tube during the drainage process.

[0010] Optionally, a sealing cover is fixedly arranged on the tank body. A first accommodating cavity is arranged between the sealing cover and the tank body. Both the first breathing tube and the second breathing tube communicate with the first accommodating cavity. A liquid inlet communicating the first accommodating cavity with the inside of the tank body is arranged on the tank body. The plugging component includes a connecting piece fixedly connected to the sealing cover and a disc arranged inside the tank body. The diameter of the disc is larger than the diameter of the liquid inlet, and the diameter of the disc is smaller than the inner diameter of the tank body.

[0011] By adopting the above technical solution, during use, when it is necessary to seal the liquid inlet by using the plugging component, the side wall of the tank body is squeezed to push the disc towards the direction of the liquid inlet and block the liquid inlet, so as to realize the sealing of the liquid inlet. During the process of the tank body collecting condensed water, the disc does not bear the action of external pressure, so that the disc disengages from blocking the liquid inlet under the action of its gravity, so that the condensed water in the first breathing tube and the second breathing tube flows into the inside of the tank body through the liquid inlet. The diameter of the disc being larger than the diameter of the liquid inlet ensures that the disc can completely block the liquid inlet.

[0012] Optionally, the plugging component further includes a plurality of blocking blocks for abutting against the side of the disc facing away from the connecting piece. The plurality of blocking blocks are fixedly arranged on the inner wall along the circumferential direction of the tank body, and a drainage channel is arranged between adjacent two blocking blocks.

[0013] By adopting the above technical solution, the retaining block is fixedly connected to the inner wall of the tank body, and when in use, the retaining block is used to support the disc, thereby ensuring the stability of the disc in a normal state and reducing the use strength of the connecting piece. In addition, the drainage channel between two adjacent retaining blocks can ensure that the condensed water flowing down from the liquid inlet is collected in the tank body.

[0014] Optionally, the connecting member is a spring, one end of the spring is fixedly connected to the cover, and the other end of the spring is fixedly connected to the disc.

[0015] By adopting the above technical solution, the connecting piece is set as a spring, so that the disc is pressed against the stop block under the action of the spring, thereby ensuring the stability of the disc when it is located on the stop block and reducing the shaking of the disc along with the tank body.

[0016] Optionally, a one-way valve for connecting to a drain pipe is disposed on the bottom surface of the tank body, and the connection direction of the one-way valve is from the inside of the tank body toward the drain pipe.

[0017] By adopting the above technical solution, a one-way valve connected to the drain pipe is arranged on the bottom surface of the tank body, thereby ensuring that the condensed water entering the drain pipe from the tank body will not flow back, thereby preventing the backflowing condensed water from polluting the interior of the tank body.

[0018] Optionally, the disc is provided with a drainage surface on the side facing the liquid inlet, and the drainage surface is arranged to smoothly transition from the center of the disc to the periphery.

[0019] By adopting the above technical solution, when condensed water flows into the interior of the tank from the liquid inlet, the drainage surface of the disc can enhance the flow effect of the condensed water, reduce the retention of condensed water on the top surface of the disc, and ensure that the condensed water located in the middle of the top surface of the disc can flow to the periphery of the disc.

[0020] Optionally, the abutment block is provided with an inclined surface, which gradually inclines downward from the side wall of the tank body to the center of the tank body, and the circumferential side wall of the disk facing away from the connecting piece abuts against the inclined surface.

[0021] By adopting the above technical solution, an inclined surface for abutting the circumferential side wall is provided on the stop block, so that in the process of squeezing the stop block to block the liquid inlet, the stop block with the inclined surface can reduce the deformation of the tank body, thereby facilitating the stop block to block the liquid inlet.

[0022] The preferred technical solution of the utility model can also produce at least the following technical effects:

[0023] 1. By providing a drain switch on the tank body that can drain condensed water at any time, during use, the first breathing tube and the second breathing tube connected to the tank body will recover the excess condensed water generated in the ventilator pipeline into the interior of the tank body for storage. During the collection process, due to the relatively large weight of the tank body, the ventilator pipeline connected to the tank body will be in a lower position. Therefore, the condensed water in the ventilator pipeline will flow towards the tank body under the action of gravity.

[0024] When the condensed water inside the tank body is full, open the drain switch, and the condensed water inside the tank body will drain out along the drain pipe. During the drainage process, medical staff can squeeze the elastic tank body to compress the internal space of the tank body, so as to facilitate the drainage of the condensed water inside the tank body. Thus, there is no need to open the tank body, reducing the problem that the tank pipeline is easily contaminated when exposed to the air. Brief Description of the Drawings

[0033] The following further elaborates on this application in conjunction with the Figures 1-3 This application embodiment discloses a condensate water collection tank for a ventilator.

[0034] Referring to Figure 1 and Figure 2 As shown, a condensate water collection tank for a ventilator includes a tank body 100, a cover 110, and a drain pipe 140. The cover 110 is fixedly connected to the top surface of the tank body 100, and a first accommodation cavity 160 is provided between the cover 110 and the top surface of the tank body 100. A liquid inlet 250 communicating with the first accommodation cavity 160 and the inner cavity of the tank body 100 is opened on the bottom surface of the tank body 100. A plugging assembly 200 for plugging the liquid inlet 250 is provided in the first accommodation cavity 160. A first breathing pipe 120 and a second breathing pipe 130 communicating with the first accommodation cavity 160 are fixedly connected to the cover 110. The drain pipe 140 is fixedly connected to the bottom surface of the tank body 100 and communicates with the inner cavity of the tank body 100, and a drain switch for controlling whether the drain pipe 140 discharges liquid is provided on the drain pipe 140.

[0035] In the embodiment of the present application, the tank body 100 is made of elastic and recoverable materials, including but not limited to rubber, latex, memory materials, etc.

[0036] Referring to Figure 2 and Figure 3 As shown, one end of the first breathing tube 120 and the second breathing tube 130 is fixedly connected to the top surface of the cover 110, and the other ends of the first breathing tube 120 and the second breathing tube 130 extend outward. In this way, it is convenient to connect the ends of the first breathing tube 120 and the second breathing tube 130 far from the cover 110 to the pipeline of the ventilator. Among them, the first breathing tube 120, the second breathing tube 130 and the axis line of the tank body 100 are arranged in a Y shape, that is, the first breathing tube 120 and the second breathing tube 130 are symmetrically arranged with respect to the tank body 100. Thus, the phenomenon of knotting and winding of the first breathing tube 120 and the second breathing tube 130 is reduced.

[0037] The connection points of the first breathing tube 120 and the second breathing tube 130 with the cover 110 are round holes, and the central extension line of the round holes passes through the center of the liquid inlet 250. That is, when the condensed water flowing in the first breathing tube 120 and the second breathing tube 130 enters the first accommodating cavity 160, it will flow in the direction of the liquid inlet 250 under the action of its gravity.

[0038] Referring to Figure 2 and Figure 3 As shown, the blocking assembly 200 includes a disc 220, a connecting member 210 and a plurality of blocking blocks 230. The connecting member 210 is used to connect the cover 110 and the disc 220, and the disc 220 is arranged in the inner cavity of the tank body 100. And the disc 220 is located directly below the liquid inlet 250, so that the disc 220 blocks the liquid inlet 250 from the inner cavity of the tank body 100. And the diameter of the disc 220 is larger than the diameter of the liquid inlet 250 to ensure the sealing performance of the disc 220 during the process of blocking the liquid inlet 250. The diameter of the disc 220 is smaller than the inner diameter of the tank body 100, which is convenient for the condensed water to flow between the circumferential side wall of the disc 220 and the inner wall of the tank body 100.

[0039] A drainage surface 240 is arranged on the side of the disc 220 facing the liquid inlet 250, and the drainage surface 240 is arranged to be inclined and smoothly transitioned from the center of the disc 220 to the circumferential side of the disc 220. In this way, the retention of condensed water on the top surface of the disc 220 is reduced, which is convenient for the condensed water to flow from the center of the disc 220 to the circumferential side and then be stored in the tank body 100.

[0040] A plurality of blocking blocks 230 are arranged inside the tank body 100, and the plurality of blocking blocks 230 are arranged along the circumferential direction of the tank body 100, and the blocking blocks 230 are fixedly connected to the inner wall of the tank body 100. The disc 220 abuts against the top surfaces of the plurality of blocking blocks 230 in the initial state. Among them, a drainage channel 190 is arranged between every two adjacent blocking blocks 230. The drainage channel 190 facilitates the condensed water flowing on the top surface of the disc 220 to flow into the interior of the tank body 100.

[0041] The blocking block 230 is provided with an inclined inclined surface 260 towards the top surface of the disc 220. The inclined surface 260 is inclined from near the middle of the tank body 100 towards the inner wall of the tank body 100, that is, the thickness of the blocking block 230 gradually increases from near the middle of the tank body 100 towards the direction close to the inner wall of the tank body 100. Thus, when the side wall of the tank body 100 is squeezed, the plurality of blocking blocks 230 move towards the center direction of the tank body 100. As a result, with the increase in the thickness of the blocking block 230, the disc 220 is driven to slide along the inclined surface 260, so that the tank body 100 can push the disc 220 close to the blocked liquid inlet 250 under a smaller deformation effect.

[0042] The connecting member 210 is a spring. One end of the spring is fixedly connected to the top surface of the cover 110, and the other end of the spring is fixedly connected to the top surface of the disc 220. Among them, the spring may not be fixedly connected to the cover 110 and the disc 220. That is, one end of the spring abuts against the top surface of the cover 110, and the other end of the spring abuts against the top surface of the disc 220. Thus, the disc 220 abuts against the top surface of the blocking block 230 under the action of the spring.

[0043] Refer to Figure 2 and Figure 3 As shown, the drain switch is the switch shaft 150. The switch shaft 150 is slidably arranged on the drain pipe 140 along the radial direction of the drain pipe 140. The circumferential side wall of the switch shaft 150 just blocks the inner cavity of the drain pipe 140. A through hole 151 is opened on the switch shaft 150 along its radial direction. When drainage work needs to be carried out, the switch shaft 150 is pushed to move so that the through hole 151 communicates with the inner cavity of the drain pipe 140, so that the drain pipe 140 discharges the condensed water inside the tank body 100. When the drainage is over, the switch shaft 150 is pulled to move so that the through hole 151 is completely misaligned with the inner cavity of the drain pipe 140, so as to achieve the closing function.

[0044] A sealing cover 110 is also sleeved on the end of the drain pipe 140 far away from the tank body 100. The sealing cover 110 can achieve the secondary sealing and anti-pollution functions of the drain pipe 140.

[0045] A one-way valve 180 is further provided inside the tank body 100. Among them, a second accommodation cavity 170 is formed in the bottom surface of the tank body 100. The one-way valve 180 is embedded in the second accommodation cavity 170, and both ends of the one-way valve 180 communicate with the inner cavity of the tank body 100 and the drain pipe 140. The one-way valve 180 is a duckbill one-way valve 180, and the communication direction is from the inner cavity of the tank body 100 towards the inside of the water pipe. This prevents the condensed water in the inner cavity of the drain pipe 140 from flowing back into the tank body 100 and causing pollution to it.

[0046] As mentioned above, the above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
