Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an ice water spray device for alleviating the thirst of patients undergoing mechanical ventilation. Background Art

[0002] Thirst is an important physiological stimulus for maintaining body fluid homeostasis, and is mainly manifested as an urge to ingest high-water content fluids. Patients in the intensive care unit (ICU) who are intubated and ventilated via oral tracheal tube (mechanical ventilation) have a higher incidence of thirst than other patients due to factors such as mouth breathing, reduced saliva secretion, and difficulty swallowing. The feeling of thirst increases the oxygen consumption and metabolic burden of ICU patients, and can also cause negative emotions such as despair, anxiety, irritability, and powerlessness. Therefore, it is necessary to identify the patient's thirst as early as possible and intervene in a timely manner.

[0003] Studies have found that compared with normal temperature water intervention, ice water intervention can relieve patients' thirst to the greatest extent, improve patients' sleep symptoms, increase patients' comfort, and promote treatment progress. Ice water intervention mainly involves spraying ice water on the oral mucosa and tongue surface through a nozzle to stimulate cold receptors, thereby reducing severe thirst to mild thirst or no thirst.

[0004] As the research progresses, there is a spray device on the market, which includes a water storage chamber, a water pipe and an ultrasonic atomizing nozzle. A water pump is arranged in the water storage chamber. When in use, ice water is stored in the water storage chamber, and the ultrasonic atomizing nozzle is placed in the patient's mouth. The water pump and the water pipe are used to guide the ice water into the ultrasonic atomizing nozzle, and the ice water is atomized by the ultrasonic atomizing nozzle and then sprayed in the patient's mouth.

[0005] However, in order to ensure that the ice water maintains a low temperature, this spray device needs to replace the ice water several times; or set a condenser in the water storage chamber to keep the water in the water storage chamber at a low temperature. However, replacing the ice water several times is very complicated; since the amount of water required for each spraying is relatively low, setting a condenser requires condensing all the water in the water storage chamber, which is costly. Summary of the invention

[0006] The present invention is intended to provide an ice water spray device for alleviating the thirst of patients undergoing mechanical ventilation, and the present invention is intended to solve the technical problems existing in the prior art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an ice water spray device for relieving the thirst of mechanically ventilated patients, comprising a water storage chamber, a water guide pipe and an ultrasonic atomizing nozzle, the ultrasonic atomizing nozzle comprising a water inlet and a spray port, the water inlet being connected to the water guide pipe, the ultrasonic atomizing nozzle being further connected to a generator, and further comprising a flow guide pipe and a condensation chamber, one end of the flow guide pipe being connected to the bottom of the water storage chamber, the other end of the flow guide pipe being connected to the condensation chamber, a condensation element being provided in the condensation chamber; one end of the water guide pipe being away from the water inlet being connected to the condensation chamber, and one end of the water guide pipe being connected to the condensation chamber being provided with a one-way valve; further comprising a first driving element arranged in the water storage chamber and a second driving element arranged in the condensation chamber.

[0008] Beneficial effects of this technical solution:

[0009] A condensation chamber is provided, and the water in the water storage chamber is introduced into the condensation chamber by using the first driving member, and the water in the condensation chamber is condensed by the condensation member, and then the condensed water is introduced into the ultrasonic atomizing nozzle through the water conduit, and ice water spray is sprayed out through the ultrasonic atomizing nozzle to relieve the patient's thirst.

[0010] Compared with the prior art, this technical solution only needs to condense a small amount of water in the condensation chamber, the condensation cost is low, and the water condensation can be completed quickly. At the same time, the amount of ice water sprayed each time can be controlled to achieve the timing and quantitative spraying of ice water mist.

[0011] In another preferred embodiment of the present invention, the first driving member includes a driving plate vertically slidably connected in the water storage chamber and a threaded rod threadedly connected to the driving plate, and both ends of the threaded rod are rotatably connected to the water storage chamber; a motor is also fixed on the water storage chamber, a fan-shaped gear is fixed on the output shaft of the motor, and a driven gear meshing with the fan-shaped gear is coaxially fixed on the threaded rod.

[0012] Beneficial effect: the motor drives the sector gear to rotate. When the sector gear rotates to engage with the driven gear, the driven gear drives the threaded rod to rotate. The threaded rod is threadedly connected to the driving plate. Therefore, the driving plate will slide along the water storage chamber, thereby squeezing the water in the water storage chamber. The water in the water storage chamber will be diverted to the condensation chamber through the guide pipe.

[0013] In another preferred embodiment of the present invention, the condensing chamber is fixed on the upper part of the water storage chamber, a boosting plate is vertically slidably connected in the condensing chamber, a moving rod is connected to the boosting plate, and also includes a moving part for driving the moving rod to move.

[0014] Beneficial effect: The moving part drives the moving rod to move, and then the booster plate moves accordingly, which can squeeze the condensation chamber, so that the pressure in the condensation chamber increases, and the one-way valve opens to guide the water in the condensation chamber into the ultrasonic atomizing nozzle.

[0015] In another preferred embodiment of the present invention, the moving part includes a connecting rod hinged on the water storage chamber, the moving rod is provided with a sliding hole, one end of the connecting rod passes through the sliding hole and is slidably connected in the sliding hole, and a counterweight block is fixed to the other end of the connecting rod; a driving rod is provided in the water storage chamber below the counterweight block, a rotating gear meshing with the fan gear is rotatably connected to the water storage chamber, and the driving rod is threadedly connected to the rotating gear; a torsion spring is also sleeved on the outside of the driving rod, and the two ends of the torsion spring are respectively fixed to the driving rod and the water storage chamber.

[0016] Beneficial effect: When the motor drives the sector gear to rotate to the other side, it meshes with the rotating gear, and then the rotating gear rotates. The rotating gear is threadedly connected to the drive rod, and the drive rod moves axially, thereby lifting the end of the linkage rod with a counterweight. The other end of the linkage rod moves downward to squeeze the boost plate. At this time, the torsion spring stores energy. When the sector gear rotates to the point where the rotating gear disengages, the drive rod is reset under the action of the torsion spring, which facilitates the reset of the boost plate.

[0017] In another preferred embodiment of the present invention, a return spring is provided between the pressure boosting plate and the condensation chamber.

[0018] Beneficial effect: The reset spring can assist the pressure boosting plate in resetting.

[0019] In another preferred embodiment of the present invention, a connecting hole is provided on the boosting plate, and a diverter valve is provided in the connecting hole; a switch for controlling the opening and closing of the diverter valve is also included, and the switch is located above the counterweight block.

[0020] Beneficial effect: When the driving rod moves to the top end, it drives one end of the linkage rod to squeeze the switch, controlling the diversion valve to open, so that the condensation chamber is connected to the outside through the connecting hole, thereby facilitating the resetting of the booster plate.

[0021] In summary, the present invention realizes quantitative spraying of water mist by introducing the water in the water storage chamber into the condensation chamber, and then introducing the water in the condensation chamber into the ultrasonic atomizing nozzle. Quantitatively introducing water into the condensation chamber can achieve a small amount of condensation, reduce the cost of condensation, and improve the efficiency of condensation. In combination with the first driving member and the second driving member, it is possible to intermittently introduce water into the condensation chamber and export the water in the condensation chamber.

[0034] The left end of the guide pipe 2 is connected to the bottom of the water storage chamber 1, and the right end of the guide pipe 2 is connected to the upper part of the condensation chamber 3; a condensation element 13 is provided in the condensation chamber 3 to condense the water in the condensation chamber 3.

It also includes a moving member that drives the moving rod 15 to move vertically. A return spring is provided between the top of the boost plate 14 and the top of the condensing chamber 3. In this embodiment, the return spring uses a compression spring, and the specific model is set according to actual needs.

[0035] A hollow cavity 16 is provided on the periphery of the condensation cavity 3, and a heat-insulating layer 17 is wrapped around the periphery of the hollow cavity 16, which can insulate the condensation cavity 3 and reduce heat exchange with the outside, thereby keeping the water in the condensation cavity 3 at a low temperature.

[0036] The moving part includes a connecting rod 19 and a driving rod 20. A mounting frame 18 is provided on the right side of the water storage chamber 1. The connecting rod 19 is hinged on the mounting frame 18. A sliding hole is provided on the top of the moving rod 15. The right end of the connecting rod 19 passes through the sliding hole and is slidably connected to the sliding hole. A counterweight block 21 is fixed to the left end of the connecting rod 19.

[0037] The driving rod 20 is located below the counterweight 21, and the driving rod 20 is rotatably connected to the mounting frame 18, and the driving rod 20 can slide vertically on the mounting frame 18. The top of the driving rod 20 is against the counterweight 21, and a torsion spring is sleeved on the driving rod 20, and the two ends of the torsion spring are respectively fixed to the driving rod 20 and the mounting frame 18. The top of the driving rod 20 is threadedly connected with a rotating gear 22, and the rotating gear 22 is rotatably connected to the mounting frame 18, so when the rotating gear 22 rotates, the driving rod 20 can be moved vertically. When the sector gear 11 rotates to the right, it meshes with the rotating gear 22.

[0038] The boost plate 14 is provided with a connecting hole 23, and a diverter valve 24 is provided in the connecting hole 23. A switch 25 is provided above the left end of the linkage rod 19 on the mounting frame 18, and the switch 25 is used to control the opening and closing of the diverter valve 24.

[0039] The left end of the water pipe 4 is connected to the bottom of the condensation chamber 3, and a one-way valve 26 is provided in the connection between the water pipe 4 and the condensation chamber 3. The one-way valve 26 can realize the water in the condensation chamber 3 to be discharged. The one-way valve 26 is a pressure valve, so when the booster plate 14 slides downward, the water in the condensation chamber 3 can be discharged. The inner diameter of the water pipe 4 decreases from left to right. According to the Bernoulli principle, when the water in the condensation chamber 3 is discharged through the water pipe 4, the flow rate of the water flow can be increased and the temperature of the water flow can be reduced.

[0040] The ultrasonic atomizing nozzle 5 includes a water inlet 27 and a spray port 28. The water inlet 27 is connected to the right end of the water conduit 4. A generator 29 electrically connected to the ultrasonic atomizing nozzle 5 is also included. By starting the generator 29, the water introduced into the ultrasonic atomizing nozzle 5 can be sprayed.

[0041] The specific implementation process is as follows:

[0042] The spray port 28 of the ultrasonic atomizing nozzle 5 is placed in the patient's oral cavity, and water is added into the water storage chamber 1 through the water inlet, and the water inlet is sealed with the sealing plug 6. The motor 9 is started, and the sector gear 11 is driven to rotate when the motor 9 rotates. When the motor 9 is engaged with the driven gear 12, the driven gear 12 rotates, driving the threaded rod 8 to rotate synchronously, and then the driving plate 7 moves downward, squeezing the water in the water storage chamber 1, and introducing a certain amount of water into the condensation chamber 3 through the guide tube 2.

[0043] After water is added into the condensation chamber 3, it is condensed through the condensation element 13 to form ice water.

[0044] As the sector gear 11 rotates, when the sector gear 11 meshes with the rotating gear 22, the rotating gear 22 is driven to rotate. Since the rotating gear 22 is threadedly connected to the driving rod 20, the driving rod 20 can move upward, and the torsion spring is stored. Therefore, the driving rod 20 can push the left end of the connecting rod 19 upward. According to the lever principle, the right end of the connecting rod 19 drives the moving rod 15 to move downward, and then the booster plate 14 moves downward, the pressure in the condensation chamber 3 increases, and the one-way valve 26 opens, squeezing the ice water in the condensation chamber 3 into the ultrasonic atomizing nozzle 5.

[0045] The generator 29 is started, and the ice water entering the ultrasonic atomizing nozzle 5 is atomized into water mist through the generator 29, and then sprayed into the patient's mouth to relieve the patient's thirst.

[0046] Embodiment 2:

[0047] The difference between Example 2 and Example 1 is that, in this embodiment, a condensation member 13 is provided on the inner wall of the condensation chamber 3. Figure 3 As shown, the condensing element 13 includes a housing 30 and a cooling chip 31 attached to the upper inner wall of the housing 30.

[0048] The bottom of the housing 30 is provided with heat dissipation fins 32, which extend out of the condensation chamber 3. The bottom of the housing 30 is provided with a switch for controlling the operation and shutdown of the refrigeration chip 31. The top surface of the refrigeration chip is cooled, and the bottom surface is heated, so that the top can contact with water to complete the condensation of water. The bottom is heated and the heat is dissipated outward through the heat dissipation fins, achieving the effect of heat dissipation.

[0049] Embodiment 3:

[0050] The difference between Example 3 and Example 2 is that a temperature sensor is provided in the condensing chamber, and the condensing chamber further includes a transmission module and a control module. The transmission module is used to transmit the temperature signal sensed by the temperature sensor, and the control module is used to control the opening and closing of the condensing element. When the temperature sensor senses that the temperature of the water in the condensing chamber reaches a preset temperature, the sensed signal is transmitted to the control module through the transmission module, and the control module controls the condensing element to close, thereby preventing the water temperature in the condensing chamber from being too low, and realizing the regulation of the water temperature in the condensing chamber.
