Description

Technical Field

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

[0002] In modern clinical medicine, the autonomous ventilation function of the ventilator has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupies a very important position in the field of modern medicine. Mechanical ventilation can improve or correct hypoxia by increasing the patient's ventilation volume, improving the patient's gas exchange and reducing the work of the respiratory muscles. When using a ventilator, a humidifier is required to increase the humidity and temperature of the patient's inhaled gas to prevent the patient's airway from drying out. In this process, the humidifier will heat the water to a certain extent and produce a certain amount of water vapor. The temperature of the gas heated by the humidifier and the gas exhaled from the patient's respiratory tract is often higher than the room temperature, causing part of the gas to condense in the ventilator pipeline to form condensed water.

[0003] Condensed water contains more or less of the patient's airway secretions, where pathogens often parasitize and multiply rapidly. In addition, during operations such as turning over, the accumulated condensed water may flow back into the respiratory tract, which will not only affect normal assisted ventilation, but also lead to the occurrence of ventilator-associated pneumonia.

[0004] The condensate collection device currently used in clinical practice has a small volume and can only collect 45 ml of condensate. The preventive measures for ventilator-associated pneumonia require that when the condensate reaches half of the water collection cup, the water collection cup must be unscrewed in time to pour the condensate into the collection bucket next to the bed. Currently, the condensate is collected by the nurse unscrewing the water collection cup and pouring the condensate into the collection bucket next to the bed. The collection bucket contains disinfectant water prepared by adding a certain amount of chlorine-containing disinfectant to 500 ml of water. Each time the condensate is poured, the contaminated liquid in the bucket will be exposed to the air for a long time. At the same time, because it is placed next to the bed, the collection bucket may overturn if not carefully placed, which will pollute the surrounding air and cause harm to medical staff. During use, nurses are required to frequently disconnect the water collection cup from the ventilator pipeline to dump the water, which increases the nurses' workload. Nurses are often busy and fail to dump the condensed water in time. The retention of condensed water will increase airway resistance and cause condensed water to directly enter the lower respiratory tract, aggravating lung infection. At the same time, condensed water often drips onto the ground or contaminates the operator's hands during the disconnection process. When the gas in the ventilator pipeline rushes out at the moment of disconnection, the gas and condensed water containing a large amount of bacteria will pollute the air and the bodies of medical staff, causing the spread of pathogens.

[0005] Therefore, it is necessary to improve the condensate collection device to address the problems of frequent dumping, untimely dumping, open dumping, and open disinfection of the above-mentioned ventilator condensate, which cause heavy workload for nurses, increase the risk of lung infection in patients, increase the risk of pathogen transmission, and increase the risk of occupational exposure for medical staff.

[0006] Application number: CN201520261428.1, the name of the utility model is: "A ventilator condensate collection cup with alarm function" which records:

[0020] The working process of the utility model: the collection cup body 1 is a sealed cup body, and condensate enters the cup body. As the condensate increases, the liquid level will continue to rise, and the float body 6 will also rise with the liquid level. When it rises to the set alarm water level, the metal guide plate 7 on the float body 6 abuts against the two connecting guide rods 3. At this time, the alarm circuit will be connected, and the alarm 4 will sound an alarm to remind medical staff to drain the liquid in time. When draining the liquid, medical staff only need to connect other sealed bottles to the drain port 11, and then open the drain valve 12 to drain the condensate. The whole process does not need to contact the condensate, and the condensate is also in a sealed state, which is relatively safe and hygienic.

[0007] The two connecting guide rods 3 of the alarm circuit are set in the collection cup body 1. During use, the alarm circuit may be connected due to the condensed water on the inner wall of the cup body containing the patient's respiratory secretions. It is possible that the alarm circuit will be falsely triggered in advance as the collection cup body 1 shakes. There is no improvement for false triggering. In addition, when discharging unsterilized condensed water, no consideration is given to how to reliably disinfect it, which may cause false triggering of the alarm circuit, increase the risk of pathogen transmission, and increase the risk of occupational exposure of medical staff.

[0041] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0042] The following is a further description of the condensate collection device for the ventilator pipeline of the utility model in combination with the accompanying drawings and specific embodiments: As shown in the figure, the first embodiment contains a condensate temporary storage tank 3, a liquid level alarm device 5, a condensate collection tank 8 and a condensate disinfection and discharge device 7. The upper side of the condensate temporary storage tank 3 is arranged at the sagging bend of the ventilator pipeline 2 through a Y-type joint 3-1, and a liquid level alarm device 5 is arranged in the middle of its side. The lower side is connected to the condensate collection tank 8 in the middle of the ventilator 12 through a transfer valve 11 and a condensate transfer pipe 10. The condensate in the condensate collection tank 8 is discharged into the wastewater tank 6 through the disinfection and discharge device, wherein the liquid level alarm device 5 includes a shell 5-1, a power supply 5-2, and an alarm 5-3. -3, a positioning cannula 5-11, a trigger tube 5-4 and a trigger water absorption bag 5-5, the shell 5-1 is connected to the trigger tube 5-4 through the positioning cannula 5-11, an adjacent trigger electrode 5-9 is arranged inside the trigger tube 5-4, the trigger electrode 5-9 is connected in series with a power source 5-2 and an alarm 5-3 in sequence through a wire 5-10 passing through the positioning cannula 5-11, the trigger water absorption bag 5-5 is located on the upper side of the trigger tube 5-4, and contains a flexible shell 5-1 and a water absorption block 5-7', wherein a water inlet hole 5-6 is arranged on the side of the shell 5-1, and a water absorption block 5-7' is arranged inside; a sleeve 3-4 is arranged in the middle of the side of the condensate storage tank 3, and a trigger water absorption bag 5-5 and a trigger tube 5-4 are arranged inside the sleeve 3-4.

[0043] The absorbent block 5-7' is a sponge, such as a common PVA sponge or other common high-density sponge. A trigger protrusion 5-8 is provided on the side where the trigger absorbent bag 5-5 contacts the trigger tube 5-4. When the condensed water in the condensed water storage tank 3 reaches about half of its capacity, the liquid level alarm device 5 is triggered, reminding the medical staff to transfer the condensed water in the condensed water storage tank 3, raise the condensed water storage tank 3 higher than the condensed water collection tank 8, open the transfer valve 11 on the lower side, and allow the condensed water in the condensed water storage tank 3 to flow into the condensed water collection tank 8 in the middle of the ventilator 12 through the condensed water transfer pipe 10, and then close the transfer valve 11, lower the height of the condensed water storage tank 3, and carry out the next round of collection.

[0044] The ventilator tube 2 is connected to the tracheal tube of the patient on the bed 1, and the lower part of the middle of the ventilator tube 2 is connected to the condensed water storage tank 3 through the Y-type connector 3-1, and the condensed water will flow into it. The pull rope 4 can be tied to the appropriate position of the ventilator tube 2, which can correct the vertical position of the condensed water storage tank 3 in the natural state, and prevent it from being in a tilted state. Insufficient condensed water triggers the liquid level alarm device 5 in advance, shortening the time interval for pouring the condensed water, or mistakenly reminding medical staff.

[0045] like Figure 2-5 The first embodiment of the liquid level alarm device 5 is shown. The liquid level alarm device 5 allows condensed water to penetrate into the inside of the device, so that the absorbent block 5-7' expands appropriately in volume after absorbing water, and its weight increases. The outer wall of the trigger absorbent bag 5-5 is selected to be made of flexible material. The deformation of the lower side surface plus its own gravity will press the trigger protrusion 5-8 against the trigger tube 5-4 below it. The outer wall of the trigger tube 5-4 is also made of flexible material. At this time, the distance between adjacent trigger electrodes 5-9 arranged up and down in the trigger tube 5-4 will gradually decrease until they touch. The circuit between the alarm 5-3 and the power supply 5-2 is connected through the wire 5-10. At this time, the alarm 5-3 will continue to sound, reminding medical staff to transfer the condensed water in the condensed water storage tank 3 into the condensed water collection tank 8 in time. When the patient is turned over, the condensed water in the ventilator pipeline 2 will sway back and forth, and insufficient condensed water will enter the trigger water absorption bag 5-5 and be absorbed into it, which is not enough to trigger the liquid level alarm device 5 in advance. Here, the time interval for pouring the condensed water can be effectively separated to reduce the probability of falsely reminding medical staff. When the medical staff transfers the condensed water, they need to pinch the water absorption block 5-7' through the outer wall of the trigger tube 5-4, squeeze the water inside into the condensed water temporary storage tank 3, and then release their fingers. Since the weight will be reduced and the volume may also be slightly reduced, the trigger electrode 5-9 in the trigger tube 5-4 will be disconnected and the alarm sound will be released. After the pipeline is tidied, the next round of condensed water collection will be carried out.

[0046] The water inlet hole 5-6 set on the trigger water absorption bag 5-5 has a slightly smaller size and can be multiple in number, so that the water absorption block 5-7' can absorb the slowly infiltrating condensed water through it and slowly absorb the condensed water that is about to reach the tipping warning line. When the liquid level of the condensed water is at the tipping warning line and remains for a period of time, a sufficient amount of condensed water will penetrate into the water absorption block 5-7' through the water inlet, causing its volume or mass to change significantly, thereby accurately and effectively pressing down the trigger protrusion 5-8 to trigger, so that the trigger electrode 5-9 adjacent to the trigger tube 5-4 of the flexible tube wall contacts, thereby generating an alarm switch signal to remind medical staff.

[0047] One end of the positioning cannula 5-11 is connected to the housing 5-1, and the other end is inserted into the sleeve 3-4 on the side of the condensed water collection tank 8. The cross-section of the two after being plugged in can be cylindrical or square, and is designed to be a detachable structure for easy replacement and maintenance. A limiting protrusion 3-5 is provided on one side of the sleeve 3-4 near the condensed water temporary storage tank 3, which can prevent the triggering water absorption bag 5-5 from sliding into the condensed water temporary storage tank 3, avoiding unnecessary maintenance workload for medical staff and reducing the probability of handling unsterilized condensed water.

[0048] A second embodiment of a condensate collection device for a ventilator pipeline comprises a condensate temporary storage tank 3, a liquid level alarm device 5, a condensate collection tank 8 and a condensate disinfection discharge device 7. The upper side of the condensate temporary storage tank 3 is arranged at the sagging bend of the ventilator pipeline 2 through a Y-type joint 3-1, and a liquid level alarm device 5 is arranged in the middle of the side thereof. The lower side is connected to the condensate collection tank 8 in the middle of the ventilator 12 through a transfer valve 11 and a condensate transfer pipe 10. The condensate in the condensate collection tank 8 is discharged into the wastewater tank 6 through the disinfection discharge device, wherein the liquid level alarm device 5 comprises a shell 5 -1, power supply 5-2, alarm 5-3, positioning cannula 5-11, trigger tube 5-4 and air float 5-7, housing 5-1 is connected to trigger tube 5-4 through positioning cannula 5-11, trigger tube 5-4 is provided with adjacent trigger electrode 5-9, trigger electrode 5-9 is connected in series with power supply 5-2 and alarm 5-3 in sequence through wire 5-10 passing through positioning cannula 5-11, air float 5-7 is located at the lower side of trigger tube 5-4; sleeve 3-4 is provided on the side of condensate temporary storage tank 3, air float 5-7 and trigger tube 5-4 are provided in sleeve 3-4. Air float 5-7 is a square body or a cylinder, with air provided in the hollow inside and trigger protrusion 5-8 provided on the top.

[0049] like Figure 6-10The figure shows a second embodiment of the liquid level alarm device 5. The liquid level alarm device 5 allows condensed water that reaches the warning liquid level to penetrate into the interior thereof, which will cause the air float 5-7 to generate buoyancy upwards when it meets water. When the liquid level is sufficient, sufficient upward buoyancy will be generated. At this time, the trigger protrusion 5-8 on the upper side of the air float 5-7 will push the adjacent trigger electrode 5-9 in the flexible material trigger tube 5-4 above it, thereby connecting the circuit between the alarm 5-3 and the power supply 5-2 through the wire 5-10. At this time, the alarm 5-3 will continue to sound, reminding medical staff to promptly dump the condensed water in the condensed water storage tank 3 into the condensed water collection tank 8. When the patient is turned over, the condensed water in the ventilator pipeline 2 sways back and forth, and insufficient condensed water will enter the vicinity of the air float 5-7. Since the condensed water passes through the limit baffle 3-5' with mesh 3-6, the condensed water will not immediately flow into the vicinity of the air float 5-7. When the liquid level is insufficient or the degree of squeezing the flexible material trigger tube 5-4 on the upper side of the air float 5-7 is insufficient, it is not easy to trigger the liquid level alarm device 5 in advance. The restriction on the triggering conditions here can effectively separate the time intervals for pouring the condensed water, and reduce the probability of falsely reminding medical staff. Even if there is a false trigger, the medical staff will visually judge whether they need to pour the condensed water as soon as possible, and the false triggering phenomenon when turning the patient over can be accepted. Finally, the insufficient condensed water will flow back into the condensed water temporary storage tank 3 through the limit baffle 3-5' with mesh 3-6, and the false triggering probability here will continue to be low.

[0050] When the condensed water in the condensed water storage tank 3 reaches about half of its capacity, the liquid level alarm device 5 is triggered, reminding the medical staff to transfer the condensed water in the condensed water storage tank 3, raise the condensed water storage tank 3 to be higher than the condensed water collection tank 8, and then open the transfer valve 11 on the lower side, so that the condensed water in the condensed water storage tank 3 flows into the condensed water collection tank 8 in the middle of the ventilator 12 through the condensed water transfer pipe 10, and then close the transfer valve 11, lower the height of the condensed water storage tank 3, and carry out the next round of collection.

[0051] The disinfection discharge device contains a flexible conduit 7-1, the upper opening of which is connected to the lower part of the condensate collection tank 8. The flexible conduit 7-1 is provided with a disinfection water supply valve 7-2, a disinfection tablet temporary storage tube 7-3, a disinfection tank 7-7 and a disinfection drain valve 7-8 from top to bottom. The disinfection water supply valve 7-2 discharges unsterilized condensate into the flexible conduit 7-1, the disinfection tablet temporary storage tube 7-3 and the disinfection tank 7-7 on the upper side of the disinfection drain valve 7-8. After disinfection, the condensate is discharged from the disinfection drain valve 7-8 into the wastewater tank 6.

[0052] The disinfection water supply valve 7-2 is a ball valve, and the disinfection water discharge valve 7-8 is an elastic clip. The disinfection tablet temporary storage tube 7-3 is a flexible hose, one end of which is provided with a sealing cap 7-5 or a plug 7-6, and the disinfection tablets 7-4 are quantitatively put in batches.

[0053] The flexible conduit 7-1 in the condensate disinfection discharge device 7 makes it possible for the tilted condensate inside to contact with the disinfection sheet 7-4, provides better operational guarantee for the rapid and complete dissolution of the disinfection sheet 7-4, and can achieve dead-angle disinfection in the condensate disinfection discharge device 7 by shaking the condensate containing disinfectant components.

[0054] The disinfection water supply valve 7-2 controls the quantitative injection of the condensate disinfection discharge device 7 into the flexible conduit 7-1 and the specified volume of condensate in the disinfection tank 7-7. A ball valve with a larger diameter or a clamp-like object is used to directly clamp the flexible conduit 7-1 to achieve a blocking effect at the clamping point. During quantitative batch disinfection, the condensate in the condensate collection tank 8 will gradually flow into the disinfection tank 7-7 and the flexible conduit 7-1 connected thereto under the action of gravity, and then come into contact with the disinfection sheet 7-4.

[0055] The end of the temporary storage tube 7-3 of the disinfection tablet can be opened, which is convenient for putting in a certain amount of disinfection tablets 7-4 in batches, so that the disinfection process can be completed in a closed space, and the conventional single exposure type large-capacity disinfection is replaced by multiple closed segmented disinfections, which can reliably reduce the contact, handling and exposure risks of unsterilized condensed water. The disinfection tablet 7-4 can be a Langsuo disinfection tablet 7-4, a Junlida disinfection tablet 7-4 or an 84 effervescent tablet, etc., which can be separated into small pieces with tools in advance before being put in, thereby further shortening its dissolution time. The cap 7-5 and the plug 7-6 are both seals, and any one of the shapes can complete the sealing of the end of the temporary storage tube 7-3 of the disinfection tablet. The disinfection tank 7-7 is an expandable tank body that increases the internal volume of the condensed water disinfection discharge device 7, and its size determines the volume of condensed water for a single disinfection, thereby accurately determining the amount of disinfection tablets 7-4 to be put in according to the volume. The disinfection drain valve 7-8 is a switch for discharging the condensed water after disinfection. It can adopt a ball valve with a slightly larger diameter, or use a clamp-like object to directly clamp the flexible conduit 7-1 to achieve a blocking effect at the clamping point. A counterweight 3-3 is provided on the lower side of the condensed water temporary storage tank 3, and the Y-type connector 3-1 is connected to one side of the ventilator pipeline 2 through a drawstring 4.

[0056] The counterweight 3-3 can keep the condensed water storage tank 3 in an upright position, reduce the possibility of violent shaking of the condensed water storage tank 3 when medical staff turn the patient over, reduce the probability of false triggering of the trigger electrode 5-9 by the air float 5-7 floating up or the absorbent cotton in the absorbent bag 5-5 absorbing too much condensed water and then pressing down, and reduce the workload of removing the condensed water in the absorbent cotton. A liquid level scale 3-2 is provided on the condensed water storage tank 3 and / or the waste water tank 6.

[0057] The condensed water collection tank 8 contains the condensed water to be disinfected. The condensed water is quantitatively and regularly discharged into the waste water tank 6 below the condensed water disinfection and discharge device 7 through the condensed water disinfection and discharge device 7. For example, 200 ml is disinfected at a time. The waste water tank 6 contains the disinfected condensed water. At this time, when medical staff open, carry and pour the condensed water, it will be very convenient and reliable, reducing the risk of exposure to condensed water. A liquid level scale 3-2 is provided on the outer wall of the condensed water temporary storage tank 3, which is convenient for medical staff to read the approximate volume of the current liquid level.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
