Description

Technical Field

[0001] The invention relates to medical equipment technology, and in particular to an atomization nursing device for post-operative ophthalmology. Background Art

[0002] An eye nebulizer is an ophthalmic medical device that uses ultrasonic or compressed gas technology to convert drug solutions into a mist of tiny particles, allowing the drug to act directly and evenly on the eye tissue, thereby improving the drug's absorption efficiency and therapeutic effect.

[0003] When using the existing postoperative ophthalmic atomization care device, different drug solutions need to be poured into the atomizer for atomization and then the eyes are atomized for atomization treatment. However, glucocorticoids need to be used in the early postoperative period to reduce inflammatory reactions and edema, and antibiotics need to be used to prevent and control infection. However, the atomization use time of glucocorticoids is short, while the atomization use time of antibiotics is long. Non-steroidal anti-inflammatory drugs are used for anti-inflammatory and analgesic purposes during the inflammation relief period or as a substitute for glucocorticoids. The timing and duration of use of the three are not completely consistent, so they cannot be mixed for atomization. When there are many patients in the hospital, the nurse needs to put one drug into the atomizer for atomization first, and then the patient wears the atomization eye mask to apply the atomized drug to the eye. After one drug is used up, the nurse cleans the pipeline of the atomizer, puts another drug into the atomizer for drug atomization, and the patient puts on the atomization eye mask again for atomization treatment of the eye. Therefore, when there are many patients atomized at the same time, the burden of changing drugs for the nurse is large. Summary of the invention

DETAILED DESCRIPTION

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0052] The third atomizer 63 is fixedly installed in the inner cavity of the housing 1 and is located on the side of the second atomizer 62 away from the first atomizer 61. The top of the third atomizer 63 is fixedly connected to a third mist outlet pipe 631, and the bottom of the third atomizer 63 is fixedly connected to a third air inlet pipe 632. The third mist outlet pipe 631 and the third air inlet pipe 632 are both connected to the inner cavity of the third atomizer 63.

[0053] The air intake switching unit 64 is disposed in the inner cavity of the housing 1 and is located below the atomizer unit. The air intake switching unit 64 includes:

[0054] The regulating pipe 641 is disposed below the atomizer unit. The regulating pipe 641 is fixedly connected to the first air inlet pipe 612, the second air inlet pipe 622 and the third air inlet pipe 632 respectively. The inner cavity of the regulating pipe 641 is connected to the inner cavities of the first air inlet pipe 612, the second air inlet pipe 622 and the third air inlet pipe 632.

[0055] The special-shaped piston 642 is slidably mounted in the inner cavity of the regulating tube 641. The special-shaped piston 642 is in a convex shape, and a through groove 644 is formed in the middle of the special-shaped piston 642;

[0056] The translation drive member 643 is fixedly installed on one side of the housing 1, and its output end penetrates the end of the regulating tube 641 and extends into the inside of the regulating tube 641. The outer side of the output end of the translation drive member 643 is sealed and slidably connected with the penetration point of the regulating tube 641, and the output end of the translation drive member 643 is fixedly connected with the end of the special-shaped piston 642;

[0057] The air supply pipe 65 is fixedly installed in the middle of the outer side of the regulating pipe 641 and communicated with the inner cavity of the regulating pipe 641. The other end of the air supply pipe 65 is fixedly connected to the air supply box 8, and the air supply pipe 65 is communicated with the inner cavity of the air supply box 8;

[0058] The outlet switching unit includes:

[0059] The cross joint pipe 7 is provided with four interconnected pipe joints, three of which are respectively fixedly connected to the first mist outlet pipe 611, the second mist outlet pipe 621 and the third mist outlet pipe 631, and the last pipe joint of the cross joint pipe 7 is fixedly connected to the transmission pipe 3;

[0060] The atomizing eye mask unit 2 is connected to the other end of the transmission tube 3 .

[0061] The specific implementation is as follows: the air supply unit 5 includes a driving source, which is fixedly installed at the bottom of the inner cavity of the shell 1; a crankshaft, which is fixedly installed at the output end of the driving source through a coupling; a connecting rod, which is rotatably installed on the outside of the crankshaft; a piston, which is rotatably installed on the other end of the connecting rod; the driving source drives the crankshaft to rotate, and the connecting rod converts the rotational motion of the crankshaft into reciprocating motion of the piston, compresses the air and transmits it to the air supply box 8. The driving source includes but is not limited to a motor, which is electrically connected to an external power supply through a power plug, and is also controlled by a PLC programming program. The translation drive 643 includes but is not limited to an electric telescopic rod, which is electrically connected to an external power supply, and is also controlled by a PLC programming program. The air supply unit 5 prepares high-pressure gas, and the prepared high-pressure gas is transported to the air supply box 8 for storage. The air supply box 8 plays the role of stabilizing the air pressure and storing gas, providing sufficient air source for the subsequent atomization process. The shell 1 is made of a strong and lightweight material, such as aluminum alloy or high-strength plastic, to protect the internal components and provide stable support. The nebulizer unit can be provided with multiple nebulizers. The present solution includes three independent nebulizers, a first nebulizer 61, a second nebulizer 62 and a third nebulizer 63. The first nebulizer 61, the second nebulizer 62 and the third nebulizer 63 are all medical airflow nebulizers. The model selection includes but is not limited to the Omron handheld NE-U200 nebulizer. Each nebulizer is equipped with an independent air inlet pipe and a mist outlet pipe. These nebulizers can respectively atomize different liquid medicines to meet the care needs after different ophthalmic surgeries. The air inlet switching unit 64 includes an adjusting tube 641, a special-shaped piston 642 and a translation drive 643. Driven by the translation drive 643, The special-shaped piston 642 slides in the regulating tube 641, thereby selectively opening or closing the air inlet pipes connected to each nebulizer, and the user can choose which nebulizer to use for atomization of the medicine according to the needs. When the special-shaped piston 642 is located in the middle of the inner cavity of the regulating tube 641, the gas in the air supply pipe 65 enters the second air inlet pipe 622 through the through groove 644. When the output end of the translation drive member 643 is extended to drive the special-shaped piston 642 to the end of the inner cavity of the regulating tube 641, the through groove 644 and the first The two air inlet pipes 622 are completely staggered, and the groove of the special-shaped piston 642 near one end of the translation drive member 643 allows the gas in the air supply pipe 65 to pass through. At this time, the gas in the air supply pipe 65 enters the third nebulizer 63 through the third air inlet pipe 632, and the medicine liquid in the third nebulizer 63 is atomized. Conversely, when the output end of the translation drive member 643 is shortened and drives the special-shaped piston 642 to move to the other end of the inner cavity of the regulating tube 641, the gas in the air supply pipe 65 enters the first nebulizer 61 to atomize the medicine.

[0062] The air supply pipe 65 connects the air supply box 8 and the regulating pipe 641 to ensure that the high-pressure gas can smoothly enter the atomizer through the air inlet pipe.

[0063] The gas outlet switching unit includes a cross joint pipe 7 and a transmission pipe 3. When any nebulizer is atomizing, the output nebulized medicine or nebulized liquid of the gas outlet switching unit can be isolated from the nebulizer pipes of other nebulizers and only connected to the transmission pipe 3.

[0064] A limiting ring 71 is fixedly installed on the inner side of the pipe joint connecting the cross joint pipe 7 with the first mist outlet pipe 611, the second mist outlet pipe 621 and the third mist outlet pipe 631. A through hole is opened in the middle of the limiting ring 71. A rubber spacer 72 is arranged on the side where the three limiting rings 71 are close to each other. The size of the rubber spacer 72 is larger than the size of the through hole opened in the limiting ring 71. The rubber spacer 72 is fixedly connected to the limiting ring 71 through multiple bonding points.

[0065] The specific implementation is as follows: the rubber septum 72 is made of soft medical rubber. When the pressure on the side of the mist outlet pipe away from the cross joint pipe 7 increases, the rubber septum 72 located in the mist outlet pipe bulges under the action of air pressure, and the gap between the bonding point between the rubber septum 72 and the limiting ring 71 increases. The atomized medicine flows into the cross joint pipe 7 through the gap between the bonding point between the rubber septum 72 and the limiting ring 71. The other rubber septum 72, because of the increased pressure in the cross joint pipe 7, is then pressed against the limiting ring 71, and the mist outlet pipe where it is located is isolated from the inner cavity of the cross joint pipe 7, ensuring that only the atomized medicine in the atomizer working in atomization is output by the transmission pipe 3, and will not be mixed with other medicine liquids.

[0066] Dosing tubes are fixedly installed on the top of the first atomizer 61, the second atomizer 62 and the third atomizer 63. The dosing tubes penetrate the shell 1 and extend to the top of the shell 1. A detachable dust cap is provided at one end of the dosing tube located outside the shell 1.

[0067] The specific implementation is as follows: the drug adding tube is used to add drugs or physiological saline into the nebulizer.

[0068] A power supply plug electrically connected to the air supply unit 5 is disposed outside the housing 1 .

[0069] The transmission pipe 3 is a telescopic hose.

[0070] The specific implementation is as follows: the transmission tube 3 is a telescopic hose, and the length of the telescopic hose can be adjusted according to the needs of the patient.

[0071] Pour physiological saline into one of the nebulizers and pour medicine into the rest. When the atomization of one medicine is completed, start the translation drive 643 to drive the special-shaped piston 642 to make the nebulizer filled with physiological saline to atomize, and push the remaining atomized medicine in the transmission tube 3 to the patient's eyes. At the same time, the transmission tube 3 is cleaned, and then start the translation drive 643 to drive the special-shaped piston 642 to the nebulizer filled with another medicine for atomization.

[0072] Embodiment 2:

[0073] See also Figure 2 , Figure 7 and Figure 8 This embodiment provides a technical solution based on the first embodiment: a transmission head 4 is fixedly installed at the other end of the transmission tube 3, and the other end of the transmission head 4 is connected to the atomizing eye mask unit 2. The atomizing eye mask unit 2 includes:

[0074] The eye mask frame 21 has one side fixedly mounted on the other end of the transmission head 4;

[0075] A partition block 23 is fixedly mounted in the middle of the eye mask frame 21 and divides the eye mask frame 21 into two chambers. A T-shaped through hole is formed through the partition block 23. One end of the T-shaped through hole is connected to the inner cavity of the transmission head 4, and the other two ends of the T-shaped through hole are respectively connected to the two chambers of the eye mask frame 21.

[0076] Two mist outlets 24 are symmetrically fixedly mounted on the outside of the partition block 23 and are respectively connected to the T-shaped through holes. The two mist outlets 24 are respectively located in two chambers of the eye mask frame 21;

[0077] Two adjustment rings 25, which are respectively sleeved on the outer sides of the two mist outlets 24;

[0078] The locking unit 26 is disposed outside the eye mask frame 21 and is used to adjust the angle and position of the mist outlet 24 .

[0079] The locking unit 26 includes a locking ring 262, which is movably mounted on the inner side of the top of the eye mask frame 21. The bottom of the locking ring 262 is provided with a plurality of limit blocks 263 in a circumferential array. The limit blocks 263 are fixedly connected to the locking ring 262. A groove capable of accommodating the movement of the limit blocks 263 is provided at the connection between the eye mask frame 21 and the limit blocks 263. The locking ring 262 is annular and is provided with a plurality of limit blocks 263 in a circumferential array on the inner side.

[0080] The locking ring 262 has a notch on one side, a locking rod 261 is arranged on the inner side of the locking ring 262, a plurality of tooth patterns are arranged on the outer side of the locking rod 261 in a circular array, and a knob is fixedly installed on the top of the locking rod 261.

[0081] A detachable water absorbing member 22 is provided at the bottom of the inner wall of the eye mask frame 21 .

[0082] The specific implementation is as follows: when patients undergo atomization treatment of eye drugs, different patients have different eye distances and states, and it is necessary to adjust the angle of the atomized drug to just cover the patient's eyes. When the left and right angles of the atomized atomized drug are adjusted, the locking rod 261 is driven by hand to rotate, and the teeth on the locking rod 261 drive the locking ring 262 to move and expand in the groove opened in the eye mask frame 21 along the limit block 263, and the locking ring 262 releases the limit on the locking rod 261, and then drives the adjustment ring 25 to change the angle of the mist outlet 24. When the teeth on the locking rod 261 are stuck in the teeth of the locking ring 262, the locking ring 262 retracts to fix the position of the locking rod 261. When the upper and lower angles of the atomized drug need to be adjusted, it is only necessary to pull up or press down the knob. The water absorbent 22 can be a sponge or gauze, etc., which is used to absorb the water droplets generated during atomization treatment to improve the comfort of the face.
