Description

A headband-mounted multifunctional medical nebulizer Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a head-mounted multifunctional medical nebulizer. Background Technology

[0002] Nebulized drug delivery is a treatment method that uses a nebulizer to convert medication into tiny particles, which are then inhaled and delivered directly to the respiratory tract or lungs. It is characterized by strong targeting, high local drug concentration, and minimal systemic side effects. Currently, the most commonly used nebulizers in clinical practice are oxygen-driven nebulizers. Their working principle is based on the Venturi effect; a high-speed oxygen flow creates negative pressure to draw in the medication, moving it and dispersing it into inhalable aerosol particles. This system mainly consists of an oxygen source, a nebulizer cup, connecting tubing, and a mask. Traditional nebulizers have several shortcomings in practical use: First, they are greatly affected by external posture, requiring patients to remain seated to keep the nebulizer cup vertical and ensure the medication gathers at the bottom. This is especially true when the medication volume is low; if the cup is tilted, the medication is not evenly distributed at the bottom, and the Venturi component inside the cup cannot effectively draw in the medication, reducing the nebulization volume, affecting the nebulization effect, and increasing medication residue. Second, for patients in the postoperative recovery period, holding the nebulizer for extended periods while seated is physically demanding and detrimental to their recovery. While traditional masks can be secured with straps, this requires manual binding, and the securing parts can cause excessive pressure on the patient's ears and cheeks, leading to discomfort. Therefore, there is an urgent need for a nebulizer that improves nebulization efficiency, reduces medication residue, and alleviates the burden on patients, thereby meeting clinical needs. Summary of the Invention

[0003] The present invention aims to provide a head-mounted multifunctional medical nebulizer to solve the problems of poor performance and heavy burden of using nebulizers.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A headband-type multifunctional medical nebulizer includes a nebulizing cup, a mask, and a fixing strap. The nebulizing cup is provided with an air outlet, and a movable connecting component is provided at the air outlet. The movable connecting component is connected to a connection port on the mask, so that the nebulizing cup can rotate relative to the mask. A connector is provided at the bottom of the nebulizing cup, and a counterweight is provided on the outer sleeve of the connector. The connector is connected to a trachea for oxygen input.

[0006] Both ends of the fixing strap are equipped with support arms. The support arms are used to fit against the patient's ear and cheek. The support arms are equipped with a winding assembly, which is connected to the elastic cord to tighten the elastic cord. The elastic cord is connected to the side of the mask.

[0007] Furthermore, the movable connection assembly includes a connecting sleeve, a connecting tube disposed at the end of the connecting sleeve, and a rotating ring rotatably sleeved outside the connecting tube. The connecting sleeve is connected to the air outlet, the connecting tube is connected to the connecting port, and two sets of support rods are arranged opposite to each other on the rotating ring. The ends of the support rods are rotatably connected to the atomizing cup through a connecting column.

[0008] Furthermore, the winding assembly includes a winding shaft rotatably disposed within the cavity of the support arm and an operating shaft connected to the winding shaft. The winding shaft is connected to the end of the elastic rope for winding the elastic rope. The operating shaft can move relative to the winding shaft along the axis. An elastic retaining plate is provided around the operating shaft. The elastic retaining plate is adapted to a helical tooth groove, which is formed on the support arm.

[0009] Furthermore, the fixing strap is made of flexible material, with a width of -cm, and several metal wires are embedded in the fixing strap.

[0010] Furthermore, both the fixation strap and the support arm are equipped with flexible pads for contact with the patient's skin.

[0011] Furthermore, the mask edge is provided with a soft rubber strip, the thickness of which is 6-8mm.

[0012] Furthermore, the connector is threaded and matches the thread inside the counterweight, and the two are connected by a threaded structure.

[0013] The principles and beneficial effects of the technical solution are as follows:

[0014] This invention provides a head-mounted multifunctional medical nebulizer.

[0015] 1. The movable connecting component allows the nebulizer cup to rotate in multiple directions relative to the mask. With the help of the counterweight, the center of gravity of the nebulizer cup is lowered, so that when the patient wears the mask, there is no need to deliberately maintain an upright sitting posture. The nebulizer cup can also be kept in an upright position, so that the liquid medicine inside can be better atomized, improving the continuity of nebulization. At the same time, it avoids the failure of the deposited liquid medicine to be atomized due to the tilt of the nebulizer cup, effectively reducing the liquid medicine residue, improving the utilization rate of the liquid medicine, and making the nebulization effect better.

[0016] 2. Secure the strap to the patient's head so that the support arm fits against their cheek. Align the mask with the mouth and nose, and tighten and lock the elastic cord by rotating the winding assembly. This quickly secures the mask to the patient's mouth and nose, replacing handheld use or the traditional method of using a single strap and earphone-style fixation. This method is quick to fix and does not excessively compress the patient's ears and cheeks, reducing the burden of using the device and improving user comfort. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] As shown in Figures 1-5, a head-mounted multifunctional medical nebulizer includes a nebulizing cup 1, a mask 2, and a fixing strap 3. The nebulizing cup 1 is a commonly used clinical model with a mature internal structure. By connecting to high-speed oxygen, it utilizes the Venturi effect to attract and blow the internal medication, breaking it into aerosol particles, thus achieving nebulization. Further description is unnecessary here. The nebulizing cup 1 has an air outlet 104, and a movable connecting component is located at the air outlet 104. The movable connecting component connects to the connecting port 201 on the mask 2 using a tight fit or threaded fit, allowing the nebulizing cup 1 to rotate relative to the mask 2. A connector 101 is located at the bottom of the nebulizing cup 1, and a counterweight 102 is fitted over the connector 101. The counterweight 102 is located at the bottom of the nebulizing cup 1, below the movable connecting component. The connector 101 connects to a trachea 103 for oxygen input. The trachea 103 can be connected to a hospital's oxygen supply interface, thereby inputting high-speed oxygen into the nebulizing cup 1.

[0025] Both ends of the fixing strap 3 are provided with support arms 302. The support arms 302 are used to fit against the patient's ear and cheek to provide a basic fixation for the device. The support arm 302 is provided with a winding assembly. The winding assembly is connected to the elastic rope 202 and is used to tighten the elastic rope 202. The elastic rope 202 is connected to the side of the mask 2. The end of the elastic rope 202 is wrapped around the winding assembly. The elastic rope 202 can be tightened by winding the winding assembly, thereby tightening and fixing the mask 2 to the patient's mouth and nose.

[0026] In use, after adding the medication to the nebulizer cup 1, connect the counterweight 102 to the bottom of the nebulizer cup 1, and then connect the air tube 103 to the connector 101 to deliver high-speed oxygen into the nebulizer cup 1. Then, place the fixing strap 3 on the patient's head, positioning it at the back of the patient's head. Adjust the positions of the mask 2 and the support arm 302 so that they are positioned at the patient's mouth and nose and the cheek behind the ear, respectively. After that, simply rotate the winding assembly to wind the elastic cord 202 into the support arm 302, thereby tightening the mask 2 with the elastic cord 202 and fixing it to the patient's face. This allows for quick and easy wearing, replacing the traditional hand-held method or single-strand rope fixation. This eliminates the need for the patient to hold the device throughout the entire process, reducing the burden. The fixing strap 3 and the support arm 302 also increase the contact area with the patient's skin, distributing pressure and reducing the contact between the elastic cord 202 and the patient's face, avoiding excessive local pressure. At the same time, it avoids the ears, preventing pressure on the ears and thus reducing the pressure on the patient caused by the fixed mask 2, effectively improving the comfort of the device.

[0027] When a patient wears mask 2, if they are not in a seated position, their forward bending, backward bending, or lateral bending will cause mask 2 to deflect at a certain angle relative to the horizontal plane. At this time, under the action of counterweight 102, the nebulizer cup 1 is affected by gravity and rotates relative to mask 2 through the movable connecting component. It is not affected by the tilt angle of mask 2, so that the nebulizer cup 1 remains roughly vertical, allowing the liquid inside to be better atomized. This avoids the liquid from settling and failing to be atomized due to the tilt of the nebulizer cup 1, effectively reducing liquid residue and improving the utilization rate of the liquid. At the same time, it reduces the impact of the patient's posture on the nebulization effect, allowing patients in the recovery period and those who are physically weak to use a semi-reclining or semi-lateral reclining position for nebulization, reducing the burden on the patient and improving the effectiveness of the device. This makes the device more complete and meets the needs of clinical use.

[0028] In this embodiment, the movable connection assembly includes a connecting sleeve 105, a connecting tube 107 disposed at the end of the connecting sleeve 105, and a rotating ring 106 rotatably sleeved outside the connecting tube 107. The connecting sleeve 105 is connected to the air outlet 104, and the connecting tube 107 is connected to the connecting port 201. Two sets of support rods 108 are arranged opposite each other on the rotating ring 106, and the ends of the support rods 108 are rotatably connected to the nebulizer cup 1 through connecting posts 109. The connecting sleeve 105 can easily deform under force, allowing the connecting tube 107 to be flexibly connected to the nebulizer cup 1. After the connecting tube 107 is connected to the mask 2, the nebulizer cup 1 is supported by the support rods 108. The rotating ring 106 can rotate relative to the connecting tube 107. At the same time, the connecting sleeve 105 undergoes torsional deformation, allowing the nebulizer cup 1 to rotate left and right relative to the mask 2, thereby adapting to the patient's lateral flexion. This ensures that even if the patient tilts left or right or lies on their side, the mask 2 always fits snugly against the patient's face, but the nebulizer cup 1 does not... Affected by the mask 2, it remains vertical; the end of the support rod 108 can rotate around the connecting column 109, so that the nebulizer cup 1 can rotate in the front-back direction relative to the mask 2 at the end of the support rod 108, adapting to the patient's flexion or extension, so that even if the patient is bent over or semi-reclined, the nebulizer cup 1 always remains vertical and will not affect its working state, allowing the patient to adopt a relatively comfortable position for nebulization without having to adopt a sitting posture, actively maintaining the vertical state of the nebulizer cup 1. Through the automatic adjustment of the device, the burden on the patient is reduced, while improving the nebulization efficiency.

[0029] In this embodiment, the winding assembly includes a winding shaft 303 rotatably disposed within the cavity of the support arm 302 and an operating shaft 304 connected to the winding shaft 303. The winding shaft 303 is connected to the end of the elastic rope 202 for winding the elastic rope 202. The operating shaft 304 can move along the axis relative to the winding shaft 303, but cannot rotate relative to the winding shaft 303. An elastic clamping plate 305 is provided around the operating shaft 304. The elastic clamping plate 305 is adapted to a helical groove 306, which is formed on the support arm 302. The elastic clamping plate 305 is inclined around the operating shaft 304, with the inclination direction of the helical groove 306 being consistent with that of the helical groove 306. By rotating the operating shaft 304, the winding shaft 303 can be driven to rotate, thereby winding and tightening the elastic rope 202 to fix the face mask 2. While the operating shaft 304 rotates, the elastic clamping plate 305 can deform and engage with the helical groove 306. The device separates the elastic plate 305 from the winding shaft 303 to prevent interference with the rotation of the operating shaft 304. When the operating shaft 304 stops rotating, the elastic plate 305 remains within the helical tooth groove 306 under elastic action. The helical tooth groove 306 restricts the elastic plate 305, preventing the operating shaft 304 from driving the winding shaft 303 to rotate and causing the elastic rope 202 to loosen. This achieves one-way locking. To loosen the elastic rope 202, simply pull the operating shaft 304 to move it along the axis of the winding shaft 303, causing the elastic plate 305 to displace and separate from the helical tooth groove 306, thus releasing the lock on the operating shaft 304 and allowing it to drive the winding shaft 303 to rotate. To relock, push the operating shaft 304 to re-engage the elastic plate 305 into the helical tooth groove 306. This allows the device to quickly and easily tighten and loosen the elastic rope 202, making operation simple and convenient. It replaces manual knot tying and improves work efficiency.

[0030] In this embodiment, the fixing strap 3 is made of flexible material and has a width of 3-4 cm. Several metal wires are embedded in the fixing strap 3. The flexible material of the fixing strap 3 can better fit the head of different patients. The 3-4 cm width provides sufficient contact area to distribute pressure and avoid excessive pressure on the patient's head. Combined with the metal wires in the cavity, it provides sufficient support strength to support the entire device. At the same time, the metal wires are malleable and can be bent at will to fit the back of the patient's head. The support arm 302 can increase its contact area with the patient's cheek, and its end is closer to the patient's mouth and nose, reducing the contact between the elastic rope 202 and the patient's face and improving the comfort of use.

[0031] In this embodiment, both the fixing strap 3 and the support arm 302 are provided with flexible pads 301 for contact with the patient's skin. The flexible pads 301 can be made of polyvinyl alcohol sponge from the prior art, which has good flexibility, breathability and water absorption. It can absorb sweat in direct contact with the patient's skin, reduce stuffiness, make the device feel better, and improve the patient's acceptance.

[0032] In this embodiment, the edge of the mask 2 is provided with a soft rubber strip, the thickness of which is 6-8mm. The 6-8mm thick soft rubber strip can deform sufficiently, making the edge of the mask 2 fit the patient's face better and be more flexible, thus improving comfort.

[0033] In this embodiment, the connector 101 is provided with threads that are compatible with the threads provided in the counterweight 102, and the two are connected by a threaded structure. Connecting the counterweight 102 to the connector 101 via the threaded structure allows for quick and easy assembly and disassembly of the counterweight 102, facilitating the selection of counterweights 102 of different masses according to actual needs and improving the practicality of the device.

[0034] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific technical solutions or characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
