Description

Technical Field

[0001] The present invention relates to the technical field of ventilator water collection cups, and specifically relates to a zero-contact closed ventilator water collection system and method. Background Art

[0002] During the use of a 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 patients. However, the prior art faces many challenges in dealing with this problem.

[0003] First of all, traditional methods usually require discharging the condensed water in the water collection cup in a shutdown state, which is obviously not feasible in long-term use scenarios because shutdown not only interrupts the patient's respiratory support but also may pose a threat to the patient's life and health. Therefore, it is particularly important to develop a technology that can safely discharge condensed water while the ventilator is continuously running.

[0004] Secondly, the condensed water may contain various germs and microorganisms. If it comes into contact with the external 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, during the discharge of condensed water, it is necessary to ensure that the entire process is closed and in zero contact with the outside world to avoid the spread of germs.

[0005] In response to the above problems, the prior art has not provided an effective solution that can both discharge condensed water while the ventilator is continuously running and ensure that the entire discharge process is closed and in 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 long-term use scenarios of the ventilator, while ensuring the safety and sterility during the discharge process. Summary of the Invention

[0006] 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 safe discharge of condensed water in the water collection cup while the ventilator is continuously running, without the need for shutdown operations, solving the problem that shutdown to discharge condensed water in long-term use scenarios may interrupt the patient's respiratory support and threaten the patient's life and health; during the discharge of condensed water, it can ensure that the entire process is closed and in zero contact with the external environment, and the condensed water is always enclosed inside the water collection cup or the water discharge bag during the discharge process, avoiding direct contact with the external environment, effectively preventing the spread of germs 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:

[0008] A zero-contact closed ventilator water collection system includes a water collection cup and also includes a water discharge bag. The water discharge bag is detachably connected to the bottom of the water collection cup through a zero-contact closed connection structure.

[0009] The zero-contact closed connection structure includes a connector I provided on the water collection cup and a connector II provided on the water discharge bag.

[0010] The connector I is provided at the bottom of the cup body. A threaded hole, a core hole I, a tapered hole, and a core hole II are sequentially provided from bottom to top at the center of the connector I. A tapered surface communicating with the tapered hole and a water discharge hole I communicating with the middle of the core hole I are provided inside the connector I.

[0011] The connector II is provided at the top of the water discharge bag. The water discharge bag is composed of a hard bag cover at the top and a soft bag body at the lower part. The connector II is provided on the hard bag cover, and a core hole III is provided at the center of the connector II.

[0012] A core shaft I is installed in the core hole I. The lower part of the core shaft I is airtightly inserted into the core hole I. A conical block is provided in the middle of the core shaft I. The conical surface of the conical block is airtightly fitted with the conical surface of the tapered hole, and the conical block is in clearance fit with the core hole II. An elastic pressing mechanism that always gives a downward pressing force to the core shaft I is provided inside the cup body; when the core shaft I is at the lower limit position, the conical block presses and fits on the tapered hole to block the water discharge hole I.

[0013] A core shaft II is airtightly installed in the core hole III. A water discharge hole II communicating with the upper side and the bottom center of the core shaft II is provided on the core shaft II. An annular water storage groove communicating with the water discharge hole II is provided on the outer periphery of the upper part of the core shaft II. A locking device for the upper and lower limit positions of the core shaft is provided on the hard bag cover; an external thread matching with the threaded hole is provided on the outside of the upper part of the connector II.

[0014] The locking device for the upper and lower limit positions of the core shaft includes a locking rod. The locking rod can horizontally move through the outside of the connector II into the core hole III. A circle of locking grooves for the upper and lower limit positions and matching with the end of the locking rod is provided on the core shaft II. An elastic locking mechanism that always gives a force to the locking rod in the inner direction is provided on the hard bag cover.

[0015] The elastic pressing mechanism includes a spring I. A guide frame is provided at the bottom of the barrel of the cup body. A guide hole with a clearance fit with the upper part of the core shaft I is provided at the top of the guide frame. The spring I is installed between the conical block and the top of the guide frame. A water passing hole is provided at the bottom of the guide frame.

[0016] The elastic locking mechanism includes a locking frame and a spring III. The locking frame is fixed on the hard bag cover. A boss is provided in the middle of the locking rod. The boss is inside the locking frame, and a spring III is installed between the boss and the locking frame.

[0017] A zero-contact closed ventilator water collection method uses a water collection cup to collect condensed water in the ventilator breathing circuit. When it is necessary to drain the condensed water in the water collection cup, a water discharge 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 drained from the water collection cup into the water discharge bag. After the water discharge is completed, the water discharge bag is removed from the water collection cup. After removal, the water collection cup and the water discharge bag are respectively in zero-contact closure with the outside.

[0018] When using the water collection cup to collect condensed water in the ventilator breathing circuit, the conical block of the mandrel I is pressed tightly against the conical hole of the connector I through an elastic pressing mechanism to disconnect the upper part of the water discharge hole I from the inside of the cup body of the water collection cup, and the condensed water inside the water collection cup is in zero-contact closure with the outside.

[0019] When it is necessary to drain the condensed water in the water collection cup, first fixedly connect the upper part of the water discharge bag to the bottom of the water collection cup. After connection, the connector II at the top of the water discharge bag is airtight and fitted with the connector I at the bottom of the water collection cup, so that the core hole I in the water collection cup and the core hole III in the water discharge bag are connected and in zero-contact closure with the outside. Loosen the locking device for the upper and lower limit positions of the mandrel, push the mandrel II upward. After the mandrel II fits with the mandrel I, it pushes the mandrel I upward to the upper limit position, and use the locking device for the upper and lower limit positions of the mandrel to lock the mandrel II at the upper limit position. The water discharge hole I is connected to the inside of the cup body and communicates with the water storage tank. The water in the cup body flows into the water discharge bag through the water discharge hole I, the water storage tank and the water discharge hole II in a zero-contact closed manner with the outside.

[0020] After the drainage is completed, loosen the locking device for the upper and lower limit positions of the mandrel. The mandrel I pushes the mandrel II and the mandrel I downward under the action of the pressing mechanism. When the mandrel I and the mandrel II reach the lower limit position, the mandrel I plugs the water discharge hole I, and use the locking device for the upper and lower limit positions of the mandrel to lock the mandrel II. Unscrew the water discharge bag from the bottom of the water collection cup. The condensed water is always in zero-contact closure with the outside and is always closed inside the water collection cup or the water discharge bag throughout the process.

[0021] Pull the locking rod outwards to loosen the locking device for the upper and lower limit positions of the mandrel. After loosening the locking rod, the end of the locking rod is inserted into the locking groove under the action of the elastic locking mechanism to achieve locking.

[0022] The beneficial effects of the present invention are as follows:

A zero-contact closed ventilator water collection system and method disclosed by the present invention can discharge condensed water during the continuous operation of the ventilator: this system and method allow the safe discharge of condensed water in the water collection cup during the continuous operation of the ventilator without shutdown operation; this solves the problem that discharging condensed water during shutdown in long-term use scenarios may interrupt the patient's respiratory support and threaten the patient's life and health; through a unique zero-contact closed connection structure, the water discharge bag can be conveniently connected to the bottom of the water collection cup to achieve the smooth discharge of condensed water while ensuring the normal operation of the ventilator.

[0037] As Figure 1 shown, the zero - contact closed - type ventilator water collection system includes a water collection cup 1, and is characterized in that it further includes a water discharge bag 2. The water discharge bag 2 is detachably connected to the bottom of the water collection cup 1 through a zero - contact closed - type connection structure.

[0038] Based on the water collection method of the zero - contact closed - type ventilator water collection system, the water collection cup 1 is used to collect the condensed water in the ventilator breathing circuit. As Figure 2 shown, when it is necessary to discharge the condensed water in the water collection cup 1, the water discharge bag 2 is connected to the bottom of the water collection cup 1 through a zero - contact closed - type connection structure, and the condensed water in the water collection cup 1 is discharged from the water collection cup 1 into the water discharge bag 2. After the water discharge is completed, the water discharge bag 2 is removed from the water collection cup 1. After removal, the water collection cup 1 and the water discharge bag 2 are respectively in zero - contact closure with the outside.

[0039] The main innovation of the zero-contact closed ventilator water collection system is the zero-contact closed connection structure. Through this structure, the condensed water in the water collection cup 1 can be discharged to the water discharge bag 2 in a zero-contact and closed manner with the outside world under the condition that the ventilator does not stop operating. During the whole process, the condensed water only flows in the water collection cup 1 and the water discharge pipe of the water discharge bag 2. After the process is over, there is not a single drop of condensed water even on the outside of the water collection cup 1 and the water discharge bag 2 themselves. The zero-contact closed connection structure includes the connector I 1a2 arranged on the water collection cup 1 and the connector II 2c arranged on the water discharge bag 2.

[0040] As Figure 3 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 screw threads or the like. A three-way pipe 1b1 communicating with the breathing circuit of the ventilator is arranged on the cup cover 1b. The condensed water in the breathing circuit of the ventilator flows into the cup body 1a through the three-way pipe 1b1; As Figure 3 and Figure 4 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 connector I 1a2 arranged at the bottom of the cylinder 1a1. The connector I 1a2 is arranged at the bottom of the cup body 1a. A threaded hole 1a2a, a core hole I 1a2b, a tapered hole 1a2c and a core hole II 1a2d are sequentially arranged from bottom to top at the center of the connector I 1a2. A tapered surface communicating with the tapered hole 1a2c and a water discharge hole I 1a4 communicating with the middle part of the core hole I 1a2b are arranged in the connector I 1a2. A core shaft I 1c is installed in the core hole I 1a2b. The lower part of the core shaft I 1c is airtightly inserted into the core hole I 1a2b. As Figure 5 shown, a tapered block 1c1 is arranged in the middle of the core shaft I 1c. The tapered surface of the tapered block 1c1 is airtightly matched with the tapered surface of the tapered hole 1a2c, and the tapered block 1c1 is in clearance fit with the core hole II 1a2d. An elastic pressing mechanism that always gives a downward pressing force to the core shaft I 1c is arranged in the cup body 1a; When the core shaft I 1c is in the lower limit position, the tapered block 1c1 presses and fits on the tapered hole 1a2c to block the water discharge hole I 1a4.

[0041] As Figures 6 to 8 shown, the connector II 2c is arranged on the top of the water discharge bag 2. The water discharge bag 2 is composed of a hard bag cover 2a at the top and a soft bag body 2b at the lower part. For example, the hard bag cover 2a and the soft bag body 2b can be an integrally sealed bag-like structure made of transparent plastic. The hard bag cover 2a is mainly used to provide support for the connector II 2c, while the soft bag body 2b is mainly used to hold the condensed water and provide an external thrust for the core shaft II 2e described below outside it.

[0042] The connecting body II 2c is arranged on the rigid bag cover 2a. A core hole III 2c2 is arranged at the center of the connecting body II 2c. A core shaft II 2e is installed airtightly in the core hole III 2c2. A water drainage hole II 2e1 is arranged on the core shaft II 2e to connect the upper side surface and the bottom center of the core shaft II 2e. An annular water storage tank 2e2 communicated with the water drainage hole II 2e1 is arranged on the outer periphery of the upper part of the core shaft II 2e. The water storage tank 2e2 is arranged in an annular shape because it can facilitate its always being in a communicated state with the water drainage hole II 2e1. A core shaft upper and lower limit position locking device is arranged on the rigid bag cover 2a; An external thread 2c1 matched with the threaded hole 1a2a is arranged on the outside of the upper part of the connecting body II 2c.

[0043] When draining water, first fixedly connect the water drainage bag 2 to the bottom of the water collecting cup 1 through the cooperation of the external thread 2c1 and the threaded hole 1a2a. The upper end surface of the connecting body II 2c is airtightly attached to the upper end surface of the threaded hole 1a2a. After loosening the core shaft upper and lower limit position locking device, push the core shaft II 2e upward outside the soft bag body 2b. After the core shaft II 2e fits with the core shaft I 1c, it pushes the core shaft I 1c upward to the upper limit position. The core shaft upper and lower limit position locking device locks the core shaft II 2e at the upper limit position. The water drainage hole I 1a4 is communicated with the inside of the cup body 1a and is communicated with the water storage tank 2e2. The water in the cup body 1a flows into the water drainage bag 2 through the water drainage hole I 1a4, the water storage tank 2e2 and the water drainage hole II 2e1;

[0044] After the water drainage is completed, loosen the core shaft upper and lower limit position locking device. The core shaft I 1c pushes the core shaft II 2e and the core shaft I 1c downward under the action of the pressing mechanism. When the core shaft I 1c and the core shaft II 2e reach the lower limit position, the core shaft I 1c blocks the water drainage hole I 1a4, and use the core shaft upper and lower limit position locking device to lock the core shaft II 2e, and screw off the water drainage bag 2 from the bottom of the water collecting cup 1; After the water drainage bag 2 is screwed off, it can be disposed of as a whole, and there is also zero contact with the outside world during subsequent work such as handling and destruction.

[0045] The usage method of the above zero-contact closed ventilator water collecting system is as follows:

[0046] When using the water collecting cup 1 to collect the condensed water in the breathing circuit of the ventilator, the conical block 1c1 of the core shaft I 1c is pressed tightly against the conical hole 1a2c of the connecting body I 1a2 through the elastic pressing mechanism to disconnect the upper part of the water drainage hole I 1a4 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 closed with zero contact with the outside world;

[0047] When it is necessary to drain the condensed water in the water collecting cup 1, first fixedly connect the upper part of the water discharging bag 2 to the bottom of the water collecting cup 1. After connection, the connecting body II 2c at the top of the water discharging bag 2 is airtight and fitted with the connecting body I 1a2 at the bottom of the water collecting cup 1, so that the core hole I 1a2b in the water collecting cup 1 and the core hole III 2c2 in the water discharging bag 2 are communicated and are in zero-contact sealing with the outside; loosen the locking device for the upper and lower limit positions of the core shaft, push the core shaft II 2e upward. After the core shaft II 2e is in contact with the core shaft I 1c, it pushes the core shaft I 1c upward to the upper limit position, and use the locking device for the upper and lower limit positions of the core shaft to lock the core shaft II 2e at the upper limit position. The water discharging hole I 1a4 is communicated with the inside of the cup body 1a and is communicated with the water storage tank 2e2. The water in the cup body 1a flows into the water discharging bag 2 through the water discharging hole I 1a4, the water storage tank 2e2 and the water discharging hole II 2e1 in a zero-contact sealing manner with the outside;

[0048] After the drainage is completed, loosen the locking device for the upper and lower limit positions of the core shaft. The core shaft I 1c pushes the core shaft II 2e and the core shaft I 1c downward under the action of the pressing mechanism. When the core shaft I 1c and the core shaft II 2e reach the lower limit position, the core shaft I 1c plugs the water discharging hole I 1a4, and use the locking device for the upper and lower limit positions of the core shaft to lock the core shaft II 2e; unscrew the water discharging bag 2 from the bottom of the water collecting cup 1; the condensed water is in zero-contact with the outside and is always sealed inside the water collecting cup 1 or the water discharging bag 2 throughout the process.

[0049] Furthermore, the locking device for the upper and lower limit positions of the core shaft includes a locking rod 2f. The locking rod 2f can move horizontally and penetrate from the outside of the connecting body II 2c into the core hole III 2c2. As Figure 7 shown, a horizontal locking hole 2c3 is provided on the connecting body II 2c. The locking rod 2f is inserted into the locking hole 2c3 and can slide horizontally along its left and right directions. Preferably, the locking rod 2f and the locking hole 2c3 are made into an airtight sliding fit by means of setting a sealing ring, etc. A circle of locking grooves 2e3 for cooperating with the end of the locking rod 2f at the upper and lower limit positions is provided on the core shaft II 2e. Setting the locking grooves 2e3 in a circle is convenient for locking at any angle. In particular, the outer end of the locking grooves 2e3 is set to be flared outward to facilitate the insertion of the locking rod 2f. The end of the locking rod 2f is also set to be ball-shaped, and an elastic locking mechanism that can always apply a force to the locking rod 2f in the inner direction is provided on the hard bag cover 2a.

[0050] As Figure 3 shown, the elastic pressing mechanism includes a spring I 1d. A guide frame 1a3 is provided at the bottom of the barrel 1a1 of the cup body 1a. A guide hole 1a3a that is in clearance fit with the upper part of the core shaft I 1c is provided at the top of the guide frame 1a3. The spring I 1d is installed between the cone block 1c1 and the top of the guide frame 1a3. A water passing hole 1a3b is provided at the bottom of the guide frame 1a3.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.
