Description

Technical Field

[0001] The invention relates to the technical field of water collecting cups for ventilators, and in particular to a zero-contact closed water collecting system and method for ventilators. Background Art

[0002] During the use of the ventilator, especially in long-term use scenarios, a large amount of condensed water will accumulate in the water collection cup. The timely discharge of condensed water is crucial for the normal operation of the ventilator and the safety of the patient. However, existing technologies face many challenges in dealing with this problem.

[0003] First, the traditional method usually requires draining the condensed water in the water collection cup when the machine is shut down, which is obviously not feasible in long-term use scenarios, because shutting down will not only interrupt the patient's respiratory support, but may also pose a threat to the patient's life and health. Therefore, it is particularly important to develop a technology that can safely drain condensed water when the ventilator is in continuous operation.

[0004] Secondly, condensed water may contain various germs and microorganisms. If it comes into contact with the outside environment during the discharge process, it may not only pollute the environment, but also cause cross infection, posing a potential risk to patients and medical staff. Therefore, in the process of discharging condensed water, it is necessary to ensure that the entire process is closed and has zero contact with the outside world to avoid the spread of germs.

[0005] In view of the above problems, the prior art has not yet provided an effective solution that can discharge condensed water while the ventilator is in continuous operation and ensure that the entire discharge process is closed and has zero contact with the outside world. Therefore, there is an urgent need for a zero-contact closed ventilator water collection system and method to meet the condensed water discharge requirements in the long-term use scenario of the ventilator, while ensuring the safety and sterility of the discharge process. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a zero-contact closed ventilator water collection system and method. The zero-contact closed ventilator water collection system and method allow the condensed water in the water collection cup to be safely discharged while the ventilator is in continuous operation without stopping the machine for operation, thereby solving the problem that the discharge of condensed water during long-term use may interrupt the patient's respiratory support and threaten the patient's life and health. During the condensed water discharge process, it can ensure that the entire process is zero-contact and closed with the external environment. The condensed water is always sealed in the water collection cup or the water bag during the discharge process, thus avoiding direct contact with the external environment, effectively preventing the spread of pathogens and microorganisms, reducing the risk of cross infection, and ensuring the safety of patients and medical staff.

[0007] The technical solution of the present invention is as follows: A zero-contact closed ventilator water collection system comprises a water collection cup and a water discharge bag, wherein the water discharge bag is detachably connected to the bottom of the water collection cup through a zero-contact closed connection structure; The zero-contact closed connection structure includes a connector I arranged on the water collection cup and a connector II arranged on the water discharge bag; The connector I is arranged at the bottom of the cup body, and a threaded hole, a core hole I, a tapered hole and a core hole II are arranged in sequence from bottom to top at the center of the connector I, and a tapered surface connected to the tapered hole and a drain hole I connected to the middle of the core hole I are arranged in the connector I; The connector II is arranged on the top of the drain bag, which is composed of a hard bag cover on the top and a soft bag body at the bottom. The connector II is arranged on the hard bag cover, and a core hole III is arranged at the center of the connector II.

[0008] A core shaft I is installed in the core hole I, and the lower part of the core shaft I is airtightly inserted in the core hole I. A cone block is arranged in the middle of the core shaft I. The cone surface of the cone block is airtightly matched with the cone surface of the cone hole, and the cone block is gap-matched with the core hole II. An elastic clamping mechanism that always applies downward pressing force to the core shaft I is arranged in the cup body; when the core shaft I is at the lower limit position, the cone block is pressed tightly against the cone hole to block the drain hole I.

[0009] A core shaft II is airtightly installed in the core hole III, a drain hole II is arranged on the core shaft II and connected to the upper side and the bottom center of the core shaft II, an annular water storage tank connected to the drain hole II is arranged on the upper periphery of the core shaft II, and a core shaft upper and lower limit position locking device is arranged on the hard bag cover; an external thread matching the threaded hole is arranged on the outer part of the upper part of the connecting body II.

[0010] The upper and lower limit position locking device of the core shaft includes a locking rod, which can be moved horizontally from the outside of the connecting body II to penetrate into the core hole III. A circle of locking grooves that cooperate with the ends of the locking rod at the upper and lower limit positions are arranged on the core shaft II, and an elastic locking mechanism that can always apply force to the locking rod inward is arranged on the hard bag cover.

[0011] The elastic clamping mechanism includes a spring I. A guide frame is arranged at the bottom of the cylinder of the cup body. A guide hole is arranged at the top of the guide frame to match the upper clearance of the core shaft I. The spring I is installed between the cone block and the top of the guide frame. A water hole is arranged at the bottom of the guide frame.

[0012] The elastic locking mechanism comprises a locking frame and a spring III. The locking frame is fixed on the hard bag cover. A boss is arranged in the middle of the locking rod. The boss is on the inner side of the locking frame. A spring III is installed between the boss and the locking frame.

[0013] A zero-contact closed ventilator water collection method uses a water collection cup to collect condensed water in a breathing circuit of the ventilator. When the condensed water in the water collection cup needs to be discharged, a drain bag is connected to the bottom of the water collection cup through a zero-contact closed connection structure and the condensed water in the water collection cup is discharged from the water collection cup into the drain bag. After the draining is completed, the drain bag is removed from the water collection cup. After removal, the water collection cup and the drain bag are respectively closed with zero contact from the outside world.

[0014] When the water collecting cup is used to collect condensed water in the breathing circuit of the ventilator, the cone block of the core shaft I is pressed against the cone hole of the connector I through the elastic pressing mechanism to disconnect the upper part of the drain hole I from the inside of the water collecting cup, so that the condensed water inside the water collecting cup is sealed with zero contact with the outside world; When it is necessary to discharge the condensed water in the water collecting cup, first fix the upper part of the drain bag to the bottom of the water collecting cup. After the connection, the connector II at the top of the drain bag and the connector I at the bottom of the water collecting cup are airtightly fitted so that the core hole I in the water collecting cup and the core hole III in the drain bag are connected and closed with zero contact with the outside world; loosen the upper and lower limit position locking device of the core shaft, push the core shaft II upward, and after the core shaft II is fitted with the core shaft I, push the core shaft I upward to the upper limit position, and use the upper and lower limit position locking device of the core shaft to lock the core shaft II in the upper limit position, the drain hole I is connected with the inside of the cup body and the water storage tank, and the water in the cup body flows into the drain bag in a closed manner with zero contact with the outside world after passing through the drain hole I, the water storage tank and the drain hole II; After drainage is completed, release the upper and lower limit position locking devices of the mandrel. Mandrel I pushes mandrel II and mandrel I downwards under the action of the clamping mechanism. When mandrel I and mandrel II reach the lower limit position, mandrel I blocks drain hole I, and mandrel II is locked using the upper and lower limit position locking devices of the mandrel. Unscrew the drain bag from the bottom of the water collecting cup. The condensed water has zero contact with the outside world throughout the process and is always sealed inside the water collecting cup or the drain bag.

[0015] Pull the locking rod outward to release the upper and lower limit position locking device of the core shaft. After the locking rod is released, the end of the locking rod is inserted into the locking groove under the action of the elastic locking mechanism to achieve locking.

DETAILED DESCRIPTION

[0020] like Figure 1 As shown, a zero-contact closed ventilator water collection system includes a water collection cup 1, which is characterized in that it also has a water discharge bag 2, and the water discharge bag 2 is detachably connected to the bottom of the water collection cup 1 through a zero-contact closed connection structure.

[0021] The water collection method based on the zero-contact closed ventilator water collection system uses a water collection cup 1 to collect condensed water in the ventilator breathing circuit, such as Figure 2 As shown, when the condensed water in the water collecting cup 1 needs to be discharged, the drain bag 2 is connected to the bottom of the water collecting cup 1 through a zero-contact closed connection structure and the condensed water in the water collecting cup 1 is discharged from the water collecting cup 1 to the drain bag 2. After the draining is completed, the drain bag 2 is removed from the water collecting cup 1. After removal, the water collecting cup 1 and the drain bag 2 are respectively closed with zero contact from the outside world.

[0022] The main innovation of the zero-contact closed ventilator water collection system is the zero-contact closed connection structure. The zero-contact closed connection structure enables the condensed water in the water collection cup 1 to be discharged into the drain bag 2 in a zero-contact closed manner without stopping the ventilator. The condensed water only flows in the drain pipes of the water collection cup 1 and the drain bag 2 during the entire process. After the end, there is not a drop of condensed water even on the outside of the water collection cup 1 and the drain bag 2 themselves. The zero-contact closed connection structure includes a connector Ⅰ1a2 arranged on the water collection cup 1 and a connector Ⅱ2c arranged on the drain bag 2.

[0023] like Figure 3As shown, in the prior art, the water collection cup 1 is composed of a cup body 1a and a cup cover 1b, the cup cover 1b is fixedly connected to the top of the cup body 1a by means of a screw thread connection, etc., and a three-way pipe 1b1 connected to the breathing circuit of the ventilator is provided on the cup cover 1b, and the condensed water in the breathing circuit of the ventilator flows into the cup body 1a through the three-way pipe 1b1; Figure 3 and Figure 4 As shown, the present invention improves the structure of the cup body 1a. The cup body 1a is composed of a cylinder 1a1 with an upper opening and a connecting body Ⅰ1a2 arranged at the bottom of the cylinder 1a1. The connecting body Ⅰ1a2 is arranged at the bottom of the cup body 1a. A threaded hole 1a2a, a core hole Ⅰ1a2b, a tapered hole 1a2c and a core hole Ⅱ1a2d are arranged in the center of the connecting body Ⅰ1a2 from bottom to top. A tapered surface connected to the tapered hole 1a2c and a drain hole Ⅰ1a4 connected to the middle of the core hole Ⅰ1a2b are arranged in the connecting body Ⅰ1a2. A core shaft Ⅰ1c is installed in the core hole Ⅰ1a2b, and the lower part of the core shaft Ⅰ1c is airtightly inserted in the core hole Ⅰ1a2b. Figure 5 As shown, a cone block 1c1 is provided in the middle of the core shaft Ⅰ1c, the cone surface of the cone block 1c1 is air-tightly matched with the cone surface of the cone hole 1a2c, the cone block 1c1 is clearance-matched with the core hole Ⅱ1a2d, and an elastic clamping mechanism is provided in the cup body 1a to always apply downward pressing force to the core shaft Ⅰ1c; when the core shaft Ⅰ1c is in the lower limit position, the cone block 1c1 is pressed tightly against the cone hole 1a2c to block the drain hole Ⅰ1a4.

[0024] like Figures 6 to 8 As shown, the connector II 2c is arranged on the top of the drain bag 2, and the drain bag 2 is composed of a hard bag cover 2a on the top and a soft bag body 2b at the bottom. For example, the hard bag cover 2a and the soft bag body 2b can be an integrated closed bag structure made of transparent plastic. The hard bag cover 2a is mainly used to provide support for the connector II 2c, and the soft bag body 2b is mainly used to contain condensed water and provide external thrust to the core shaft II 2e described below.

[0025] The connecting body Ⅱ2c is arranged on the hard bag cover 2a, and a core hole Ⅲ2c2 is arranged at the center of the connecting body Ⅱ2c. A core shaft Ⅱ2e is airtightly installed in the core hole Ⅲ2c2. A drain hole Ⅱ2e1 connecting the upper side and the bottom center of the core shaft Ⅱ2e is arranged on the core shaft Ⅱ2e. An annular water storage tank 2e2 connected to the drain hole Ⅱ2e1 is arranged on the upper periphery of the core shaft Ⅱ2e. The water storage tank 2e2 is arranged in a ring shape because it is convenient for it to be always in a connected state with the drain hole Ⅱ2e1. The upper and lower limit position locking devices of the core shaft are arranged on the hard bag cover 2a; an external thread 2c1 matching the threaded hole 1a2a is arranged on the outside of the upper part of the connecting body Ⅱ2c.

[0026] When draining water, firstly, the drain bag 2 is fixedly connected to the bottom of the water collection cup 1 through the cooperation of the external thread 2c1 and the threaded hole 1a2a, the upper end surface of the connecting body II2c is airtightly fitted with the upper end surface of the threaded hole 1a2a, and after the upper and lower limit position locking device of the core shaft is loosened, the core shaft II2e is pushed upward outside the soft bag body 2b, and the core shaft II2e is fitted with the core shaft I1c and moves upward to the upper limit position against the core shaft I1c, and the upper and lower limit position locking device of the core shaft locks the core shaft II2e at the upper limit position, and the drain hole I1a4 is connected with the inside of the cup body 1a and the water storage tank 2e2, and the water in the cup body 1a flows into the drain bag 2 after passing through the drain hole I1a4, the water storage tank 2e2 and the drain hole II2e1; After draining is completed, release the upper and lower limit position locking devices of the mandrel, and mandrel Ⅰ1c pushes mandrel Ⅱ2e and mandrel Ⅰ1c downward under the action of the clamping mechanism. When mandrel Ⅰ1c and mandrel Ⅱ2e reach the lower limit position, mandrel Ⅰ1c blocks the drain hole Ⅰ1a4, and mandrel Ⅱ2e is locked using the upper and lower limit position locking devices of the mandrel, and the drain bag 2 is unscrewed from the bottom of the water collecting cup 1; after the drain bag 2 is unscrewed, it can be destroyed as a whole, and it is also closed with zero contact with the outside world during subsequent work such as transportation and destruction.

[0027] The method of using the above-mentioned zero-contact closed ventilator water collection system is as follows: When the water collecting cup 1 is used to collect condensed water in the breathing circuit of the ventilator, the cone block 1c1 of the core shaft Ⅰ1c is pressed against the cone hole 1a2c of the connector Ⅰ1a2 by the elastic pressing mechanism to disconnect the upper part of the drain hole Ⅰ1a4 from the inside of the cup body 1a of the water collecting cup 1, and the condensed water inside the water collecting cup 1 is sealed with zero contact with the outside world; When the condensed water in the water collecting cup 1 needs to be discharged, the upper part of the drain bag 2 is first fixedly connected to the bottom of the water collecting cup 1. After the connection, the connector Ⅱ2c on the top of the drain bag 2 and the connector Ⅰ1a2 at the bottom of the water collecting cup 1 are airtightly fitted so that the core hole Ⅰ1a2b in the water collecting cup 1 and the core hole Ⅲ2c2 in the drain bag 2 are connected and closed with zero contact with the outside world; the upper and lower limit position locking device of the core shaft is released, and the core shaft Ⅱ2e is pushed upward. After the core shaft Ⅱ2e is fitted with the core shaft Ⅰ1c, the core shaft Ⅰ1c is pushed upward to the upper limit position, and the core shaft Ⅱ2e is locked in the upper limit position with the upper and lower limit position locking device of the core shaft, and the drain hole Ⅰ1a4 is connected with the inside of the cup body 1a and the water storage tank 2e2. After the water in the cup body 1a passes through the drain hole Ⅰ1a4, the water storage tank 2e2 and the drain hole Ⅱ2e1, it flows into the drain bag 2 with zero contact and closed with the outside world; After drainage is completed, release the upper and lower limit position locking devices of the mandrel, and mandrel Ⅰ1c pushes mandrel Ⅱ2e and mandrel Ⅰ1c downwards under the action of the clamping mechanism. When mandrel Ⅰ1c and mandrel Ⅱ2e reach the lower limit position, mandrel Ⅰ1c blocks drain hole Ⅰ1a4, and mandrel Ⅱ2e is locked using the upper and lower limit position locking devices of the mandrel; unscrew the drain bag 2 from the bottom of the water collecting cup 1; the condensed water is always closed inside the water collecting cup 1 or the drain bag 2 without any contact with the outside world during the whole process.

[0028] Furthermore, the core shaft upper and lower limit position locking device includes a locking rod 2f, which can be moved horizontally from the outside of the connecting body II2c to the core hole III2c2, such as Figure 7 As shown, a horizontal locking hole 2c3 is provided on the connecting body II 2c, and the locking rod 2f is inserted in the locking hole 2c3 and can slide horizontally along the left and right directions thereof. Preferably, the locking rod 2f and the locking hole 2c3 are made into an airtight sliding fit by setting a sealing ring or the like, and a circle of locking grooves 2e3 that cooperate with the end of the locking rod 2f at upper and lower limit positions are provided on the core shaft II 2e. The locking groove 2e3 is set as a circle to facilitate locking at any angle. In particular, the outer end of the locking groove 2e3 is set as an outwardly expanded trumpet shape to facilitate the insertion of the locking rod 2f. The end of the locking rod 2f is also set as a ball head shape, and an elastic locking mechanism that can always give the locking rod 2f an inward force is provided on the hard bag cover 2a.

[0029] like Figure 3 As shown, the elastic clamping mechanism includes a spring Ⅰ1d, a guide frame 1a3 is arranged on the bottom of the cylinder 1a1 of the cup body 1a, a guide hole 1a3a is arranged on the top of the guide frame 1a3 to match the upper clearance of the core shaft Ⅰ1c, the spring Ⅰ1d is installed between the cone block 1c1 and the top of the guide frame 1a3, and a water hole 1a3b is arranged at the bottom of the guide frame 1a3.

[0030] In order to further ensure the sealing effect between the cone block 1c1 and the cone hole 1a2c in the compressed state, a cone surface sealing gasket 1c2 is fixed on the cone surface of the cone block 1c1 by gluing or other means. It is recommended to use an elastic rubber sealing gasket for the cone surface sealing gasket 1c2.

[0031] In order to further ensure the airtight effect inside the connecting body Ⅰ1a2, a sealing groove Ⅰ1a2b1 and a sealing groove Ⅱ1a2b2 are arranged in the core hole Ⅰ1a2b, and the sealing groove Ⅰ1a2b1 and the sealing groove Ⅱ1a2b2 are respectively arranged on both sides of the lower outlet of the drain hole Ⅰ1a4, and a sealing ring Ⅰ1e and a sealing ring Ⅱ1f ​​are respectively installed in the sealing groove Ⅰ1a2b1 and the sealing groove Ⅱ1a2b2.

[0032] Furthermore, the elastic locking mechanism includes a locking frame 2g and a spring III2h. The locking frame 2g is fixed on the hard bag cover 2a. A boss is provided in the middle of the locking rod 2f. The boss is on the inner side of the locking frame 2g. A spring III2h is installed between the boss and the locking frame 2g. The locking rod 2f is pulled outward to release the upper and lower limit position locking device of the core shaft. After the locking rod 2f is released, the end of the locking rod 2f is inserted into the locking groove 2e3 under the action of the elastic locking mechanism to achieve locking.

[0033] Furthermore, a spring II2d is installed between the lower end of the core shaft II2e and the connecting body II2c. The spring II2d gives the core shaft II2e an elastic force that always pushes it downward. In particular, in extreme cases, when not constrained by the elastic locking mechanism, the length of the core shaft II2e should be designed so that when the bottom contacts the bottom of the soft bag body 2b, the upper part of the core shaft II2e is still in the core hole III2c2. After the drainage is completed, when the upper and lower limit position locking devices of the core shaft are released, the core shaft II2e should be supported so that it slowly descends under the action of the spring II2d until the locking rod 2f is inserted into the locking groove 2e3 in the lower limit position.

[0034] In order to ensure the sealing effect of the connector II 2c when it is attached to the connector I 1a2, a flat sealing gasket 2j is fixedly connected to the upper end of the connector II 2c by gluing or the like. Specifically, the flat sealing gasket 2j is a circular elastic rubber gasket.

[0035] In order to ensure the airtightness of the core hole III2c2 and the core shaft II2e, a sealing groove III2c2a is provided at the upper part of the core hole III2c2, and a sealing ring III2i is installed in the sealing groove III2c2a. In particular, a sealing groove III2c2a and a sealing ring III2i are also provided at the lower part of the core hole III2c2 to ensure the airtightness of the two ends of the core hole III2c2.

When the condensed water in the water collecting cup (1) needs to be discharged, the water drain bag (2) is connected to the bottom of the water collecting cup (1) via a zero-contact closed connection structure and the condensed water in the water collecting cup (1) is discharged from the water collecting cup (1) into the water drain bag (2). After the water is drained, the water drain bag (2) is removed from the water collecting cup (1). After removal, the water collecting cup (1) and the water drain bag (2) are respectively zero-contact closed with the outside world.

8. A zero-contact closed ventilator water collection method according to claim 7, characterized in that: When the water collecting cup (1) is used to collect condensed water in the breathing circuit of the ventilator, the cone block (1c1) of the core shaft I (1c) is pressed against the cone hole (1a2c) of the connector I (1a2) by an elastic pressing mechanism to disconnect the upper part of the drain hole I (1a4) from the inside of the cup body (1a) of the water collecting cup (1), so that the condensed water inside the water collecting cup (1) is sealed without contact with the outside world; When it is necessary to discharge the condensed water in the water collecting cup (1), the upper part of the drain bag (2) is first fixedly connected to the bottom of the water collecting cup (1). After the connection, the connector II (2c) at the top of the drain bag (2) and the connector I (1a2) at the bottom of the water collecting cup (1) are airtightly fitted so that the core hole I (1a2b) in the water collecting cup (1) and the core hole III (2c2) in the drain bag (2) are connected and closed with zero contact with the outside world; the upper and lower limit position locking devices of the core shaft are loosened, and the core shaft II (2e) is moved upward. Pushing upward, the core shaft II (2e) and the core shaft I (1c) are fitted together and push the core shaft I (1c) upward to the upper limit position, and the core shaft II (2e) is locked at the upper limit position by the core shaft upper and lower limit position locking device, and the water discharge hole I (1a4) is connected with the inside of the cup body (1a) and the water storage tank (2e2), and the water in the cup body (1a) flows into the water discharge bag (2) in a closed manner with zero contact with the outside world after passing through the water discharge hole I (1a4), the water storage tank (2e2) and the water discharge hole II (2e1); After the drainage is completed, the upper and lower limit position locking devices of the mandrel are released, and the mandrel I (1c) pushes the mandrel II (2e) and the mandrel I (1c) downwards under the action of the clamping mechanism. When the mandrel I (1c) and the mandrel II (2e) reach the lower limit position, the mandrel I (1c) blocks the drain hole I (1a4), and the mandrel upper and lower limit position locking devices are used to lock the mandrel II (2e); the drain bag (2) is unscrewed from the bottom of the water collection cup (1); the condensed water is always sealed inside the water collection cup (1) or the drain bag (2) without any contact with the outside world during the whole process.

9. A zero-contact closed ventilator water collection method according to claim 7, characterized in that: The locking rod (2f) is pulled outward to release the upper and lower limit position locking device of the core shaft. After the locking rod (2f) is released, the end of the locking rod (2f) is inserted into the locking groove (2e3) under the action of the elastic locking mechanism to achieve locking.
