Description

Technical Field

[0001] The present invention relates to an atomizing drug delivery device, in particular to a breathing atomizing drug delivery device applied in the field of atomizers. Background Art

[0002] Nebulizer therapy mainly refers to aerosol inhalation therapy. The so-called aerosol refers to tiny solid or liquid particles suspended in the air. Therefore, nebulizer inhalation therapy uses an atomizing device to disperse the drug into tiny droplets or particles, suspending them in the gas and entering the respiratory tract and lungs to achieve the purpose of humidifying the airway and treating respiratory inflammation.

[0003] Most of the existing atomization devices use compressed air (gas compression type air compression atomizer) or oxygen (driving force) to pass a narrow nozzle with a high-speed airflow. According to the Venturi effect, negative pressure is generated around the nozzle, carrying the liquid in the storage tank into the high-speed airflow and crushing it into droplets of different sizes, of which more than 99% are composed of large-particle droplets. The remaining fine mist particles fall back into the storage tank through interception and collision of the nozzle and are sprayed out at a certain speed, and the particles that fall down are re-atomized.

[0004] For example, the specification of Chinese patent CN108704202B discloses a medical medication nebulizer cup, including a nebulizer cup body, which includes an upper cup body and a lower cup body, a mist outlet is provided on the side wall of the upper cup body, an air inlet is provided on the top of the upper cup body, the inner side of the air inlet extends downward to form an air inlet pipe, and a mist shield is provided at the bottom of the air inlet pipe; an air inlet nozzle is provided at the center of the bottom of the lower cup body, the air inlet nozzle is arranged toward the mist shield, and the space between the bottom of the lower cup body and the side of the lower cup body outside the air inlet nozzle constitutes a medicine storage tank; the outer side of the air inlet nozzle is covered with a flow path forming cover, the flow path forming cover is detachably connected to the air inlet nozzle, a liquid suction groove is opened on the inner wall of the flow path forming cover, and the liquid suction groove and the outer wall of the air inlet nozzle together constitute a liquid suction channel, and this structure relies on the high-speed movement of the airflow to disperse the drug solution into fine mist particles, thereby reducing the noise during atomization.

[0005] Most existing atomizers allow patients to absorb the drug through the nose or mouth by wearing a mask. The use of a mask can free the patient's hands and is more suitable for patients with weak limbs such as the elderly or children. However, the following defects still exist during the treatment process: first, many patients have poor self-regulation ability for breathing habits, especially elderly and children, who find it difficult to fully absorb the drug through breathing coordination, making it easy for the drug to overflow through the edge of the mask; second, during the treatment process, due to the discomfort of wearing the mask, the patient is likely to move the mask without authorization, which can easily cause a large amount of drug overflow. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the current respiratory nebulizer device is prone to drug spillage during use due to factors such as insufficient drug absorption and unauthorized movement of the patient, thereby affecting the treatment effect and polluting the environment.

DETAILED DESCRIPTION

[0020] The following is a detailed description of three implementation methods of the present application in conjunction with the accompanying drawings.

[0021] The first implementation method: The present invention provides a breathing atomization drug delivery device, please refer to Figure 1 , comprising a nebulizer body 1, an upper open end of the nebulizer body 1 is fixedly connected with a cover plate 2, a lower end of the nebulizer body 1 is fixedly connected with an air inlet pipe 7, an end of the air inlet pipe 7 away from the nebulizer body 1 is fixedly connected with an air outlet end of an air pump 8, an air inlet end of the air pump 8 is connected with a compressed air supply device, when in use, compressed air enters the nebulizer body 1 through the air pump 8 and the air inlet pipe 7 in sequence, and atomization of the liquid medicine in the nebulizer body 1 is achieved through the Venturi effect, which is a prior art, and the air pressure intensity of the compressed air entering the nebulizer body 1 can be controlled by the air pump 8, such as being set to three gears of low, medium and strong, so as to adapt to different patients according to needs.

[0022] The upper end of the cover plate 2 is fixedly connected with a medicine outlet pipe 3 connected with the inside of the nebulizer body 1, and one end of the medicine outlet pipe 3 away from the nebulizer body 1 is fixedly connected with a semi-soft mask 4, and the outer end of the semi-soft mask 4 is fixedly connected with an elastic band 5, and a mounting shell 6 is fixedly connected to the elastic band 5. A cushion is fixedly connected to the surface of the mounting shell 6, which can reduce the discomfort to the head when wearing it. The end of the medicine outlet pipe 3 is fixedly extended to the inner side of the semi-soft mask 4 and is fixedly connected with a catheter 10. Before use, the catheter 10 is inserted into the patient's nasal cavity, and the semi-soft mask 4 is worn on the patient's face through the elastic band 5, so that the atomized medicine can be absorbed by the patient through the medicine outlet pipe 3 and the catheter 10 by nasal inhalation. The catheter 10 can effectively reduce the dispersion of the medicine and improve the absorption rate of the medicine. After nasal inhalation of the medicine, exhalation is performed through the mouth, which can improve the absorption rate of the medicine. In addition, even if the medicine overflows from the nasal cavity, it can be further collected by the semi-soft mask 4, which is convenient for secondary absorption by the patient in the later stage, and further reduces the overflow of the medicine.

[0023] See also Figure 2 and Figure 3 The tension sensor 9 is fixedly connected to the interior of the mounting shell 6, the elastic strap 5 includes a pair of main elastic straps 51 of different lengths, the mounting shell 6 is fixedly connected between the pair of main elastic straps 51, the end of the main elastic strap 51 away from the mounting shell 6 is fixedly connected to the outer end of the semi-soft mask 4, and the outer side of the longer main elastic strap 51 is provided with an elastic rope 52 and a plurality of evenly distributed arc-shaped pieces 53, combined with Figure 4 As shown, the upper and lower ends of the arc-shaped piece 53 are fixedly connected to the outer end of the main elastic band 51, one end of the elastic rope 52 is fixedly connected to the outer end of the semi-soft mask 4, and the other end thereof moves through between the arc-shaped piece 53 and the main elastic band 51 and moves through the mounting shell 6 until it is fixedly connected to the sensing end of the tension sensor 9. A controller with a voice prompt function is fixedly connected to the atomizer body 1, and the tension sensor 9 is electrically connected to the controller.

[0024] The main elastic band 51 is made of highly elastic material, which effectively fixes the semi-soft mask 4 and the elastic strap 5 on the head. The arc-shaped piece 53 limits the elastic rope 52 and is not easy to hinder the elastic expansion and contraction of the elastic rope 52, so that the elastic rope 52 can be expanded and contracted synchronously with the main elastic band 51, thereby exerting a tensile force on the tension sensor 9, causing the tension data of the tension sensor 9 to change. When the semi-soft mask 4 is worn stably, the tension data of the tension sensor 9 remains stable. When the patient manually moves the elastic strap 5 or removes the elastic strap 5 from the head, the stretching length of the main elastic band 51 and the elastic rope 52 changes. At this time, the tension data of the tension sensor 9 changes, thereby reflecting whether the patient is using the semi-soft mask 4 and the catheter 10 normally, and effectively monitoring the patient's treatment process.

[0025] Combination Fig.11As shown, an electric-controlled valve (indicated by M in the figure) is fixedly connected to the inside of the drug outlet pipe 3 near the cover plate 2. The electric-controlled valve is electrically connected to the controller. When the electric-controlled valve is opened, the atomized drug can enter the drug outlet pipe 3 through the electric-controlled valve. At the same time, the electric-controlled valve can also control the rate of drug output, thereby reducing the discomfort caused to the patient by the fluctuation of the drug output rate. The upper end of the cover plate 2 is fixedly connected to a liquid adding tube 201 that is communicated with the inside of the nebulizer body 1. The upper end of the liquid adding tube 201 is threadedly connected to a tube cover 11, so that the drug can be conveniently added to the nebulizer body 1 through the liquid adding tube 201.

[0026] A breathing atomization drug delivery device, the use method of which comprises the following steps: S1. Add the medicine into the nebulizer body 1, insert the catheter 10 into the patient's nasal cavity, and make the semi-soft mask 4 cover the outside of the nose and mouth, as shown in FIG. Fig. 9 As shown, the elastic strap 5 is then put on the outer end of the head to fix the position of the semi-soft mask 4; S2, after fixing the semi-soft mask 4, turn on the controller, record the initial tension data of the tension sensor 9, and set a normal data range according to the initial tension data; S3, start the compressed air supply device, pass compressed gas into the nebulizer body 1, atomize the medicine, the atomized medicine is inhaled by the patient through the medicine outlet pipe 3 and the catheter 10, and then exhales through the mouth, and this is repeated to perform atomization treatment; S4, when the patient intends to manually move the semi-soft mask 4, the elastic strap 5 will be elastically deformed, causing the tension data monitored by the tension sensor 9 to change. At this time, the controller will issue a voice prompt, which on the one hand attracts the patient's attention and makes him stop his hand movements, and on the other hand, it also gives a reminder to his guardian, so that the guardian can stop the patient's behavior in time, thereby reducing the occurrence of drug spillage and affecting the treatment effect; S5. When the tension data of the tension sensor 9 fails to recover and stabilize within the normal data range within the specified time, the controller closes the electronically controlled valve to stop the atomized medicine from entering the medicine outlet tube 3 and continues to give voice prompts.

[0027] Supplementary explanation: In actual use, in addition to inserting the catheter 10 into the nasal cavity, the catheter 10 can also be inserted into the mouth and inhaled by mouth. The semi-soft mask 4 and the elastic strap 5 are also worn on the head, and the patient does not need to hold them. The patient can use the catheter 10 in a suitable way according to his or her actual situation and usage needs.

[0028] This embodiment provides double-layer protection for drug spillage by adding a catheter 10 inside the semi-soft mask 4, thereby reducing the drug loss rate. The elastic strap 5 provided with a tension sensor 9 can effectively monitor the patient's atomization treatment process, and can promptly reflect whether the patient (especially a child patient) has taken actions such as moving the semi-soft mask 4 or the catheter 10 without authorization, and give a reminder, thereby further reducing drug spillage. When the semi-soft mask 4 and the elastic strap 5 are not restored to the initial wearing state beyond the specified time, the output of the atomized drug can be suspended by closing the electronically controlled valve, so as to effectively solve the drug spillage from the source.

[0029] Second implementation method: This embodiment is based on the embodiment 1 and the structure of the semi-soft mask 4 is specifically arranged as follows: Figure 2 and Figure 5 The semi-soft mask 4 includes an arc-shaped hard cover 41 and a rubber soft cover 42 fixedly connected up and down, the medicine outlet tube 3 is fixedly connected to the arc-shaped hard cover 41, the edge end of the rubber soft cover 42 is connected to a rubber edge 43, and a pair of slideways 4101 are provided on the arc-shaped hard cover 41, and the two ends of the rubber edge 43 slide through the pair of slideways 4101 and are fixedly connected to the limiting block 44; See also Figure 5-Figure 7 A plurality of uniformly distributed ball bars 45 are fixedly connected to one end of the rubber soft cover 42 near the rubber edge 43, and a strip groove 4301 is provided at one end of the rubber edge 43 near the rubber soft cover 42. The ball bars 45 are slidably connected to the inside of the strip groove 4301. The sliding connection between the rubber soft cover 42 and the rubber edge 43 is achieved through the cooperation of the ball bars 45 and the strip groove 4301. Figure 2 As shown, in the initial state, the arc-shaped hard cover 41, the rubber soft cover 42 and the rubber edge 43 are combined to form a mask structure, and the limit block 44 is in contact with the outer surface of the arc-shaped hard cover 41. Figure 8 When the shape of the semi-soft mask 4 needs to be changed, the pair of limit blocks 44 and the rubber edges 43 connected thereto can be pulled outward along the slide 4101, and the rubber edges 43 located inside the arc-shaped hard mask 41 are gradually straightened. Since the rubber soft mask 42 cannot pass through the slide 4101, the bat 45 moves along the inside of the strip groove 4301 and gathers inside the straightened strip groove 4301. The rubber soft mask 42 changes from the initial smooth arc shape to a contracted state, and the opening size of the overall mask structure is reduced. At this time, the wearing state is as follows: Fig.10 shown.

[0030] Therefore, by adding the above structure, in step S1, the patient can selectively adjust the shape of the semi-soft mask 4 according to his own needs and habits, and make necessary changes to the coverage of the mouth. The specific method is as follows: when it is necessary to cover the mouth, the shape of the semi-soft mask 4 is not changed. When it is not necessary to cover the mouth, the pair of limit blocks 44 are pulled outward to drive the rubber edge 43 to move until the rubber edge 43 on the inner side of the arc-shaped hard mask 41 approaches horizontality and fits the area between the patient's nose and upper lip skin, and the rubber soft mask 42 is in a contracted state. At this time, the patient's mouth is exposed, and the semi-soft mask 4 covers the nose and the surrounding area alone (such as Fig.10 shown); Compared with the use mode in which both the mouth and nose are covered by the semi-soft mask 4, Fig.10 The usage method shown can prevent the patient's exhaled air from gathering inside the semi-soft mask 4 and being inhaled again by the patient, thereby improving the patient's breathing smoothness. In addition, the deformed semi-soft mask 4 not only maintains a double anti-overflow effect on the drug, but also, since there is no exhaled air in the semi-soft mask 4, the gas flow in the semi-soft mask 4 slows down. After the drug overflowing from the catheter 10 enters the semi-soft mask 4, it is more difficult to overflow, thereby increasing the probability of the drug being absorbed again.

[0031] The third implementation method: This embodiment adds the following structure based on the embodiment 1 or the embodiment 2: Fig.11 and Fig.12 The cover plate 2 is provided with a voltage stabilizer 12 located on the inner side of the atomizer body 1, and the voltage stabilizer 12 includes a single-mouth barrel 1201 fixedly connected to the lower end of the cover plate 2, and the upper open end of the single-mouth barrel 1201 is fixedly passed through the cover plate 2 and extends to the upper side thereof, and the interior of the single-mouth barrel 1201 is provided with a threaded cover 1204, a compression spring 1203 and a piston plate 1202 which are sequentially distributed from top to bottom, and the inner bottom surface of the single-mouth barrel 1201 is provided with an air hole 1206 which is communicated with the inner side of the atomizer body 1, and the side end of the single-mouth barrel 1201 is fixedly connected with a pair of air outlet pipes 1205 which are communicated with the interior thereof, and the threaded cover 1204 is threadedly connected to the inside of the upper open end of the single-mouth barrel 1201, the piston plate 1202 is slidably connected to the inside of the single-mouth barrel 1201, and the upper and lower ends of the compression spring 1203 are respectively in contact with the piston plate 1202 and the threaded cover 1204. In the initial state, the piston plate 1202 fits the inner bottom surface of the single-mouth barrel 1201, and the connection position between the air outlet pipe 1205 and the single-mouth barrel 1201 is located on the upper side of the piston plate 1202. The upper end of the air outlet pipe 1205 is fixedly passed through the cover plate 2 and communicated with the outside, and a filter screen 1207 is fixedly connected to the upper end of the air outlet pipe 1205.

[0032] In step S5 of embodiment 1, when the electric control valve is closed to stop the atomized medicine from entering the medicine outlet pipe 3, although the compressed gas will also stop supplying synchronously, there will be residual compressed gas in the air inlet pipe 7 and the air pump 8 entering the atomizer body 1, resulting in an increase in the air pressure in the atomizer body 1, and there is a risk of bottle explosion. In addition, there is also the possibility that other faults (such as improper setting of the gear position of the air pump 8) may cause the air pressure in the atomizer body 1 to increase. Therefore, in order to effectively avoid the situation of bottle explosion in the atomizer body 1, this embodiment adds a voltage stabilizer 12 with a voltage stabilizing function in the atomizer body 1: like Fig.13 As shown, when the air pressure in the nebulizer body 1 increases, the gas can enter the single-mouth barrel 1201 through the air hole 1206, pushing the piston plate 1202 to move upward and squeezing the compression spring 1203. When the piston plate 1202 moves to the upper side of the outlet pipe 1205, the air hole 1206 is connected with the outlet pipe 1205, and the excess gas can be discharged to the outside through the outlet pipe 1205. The air pressure in the nebulizer body 1 drops, reducing the risk of the nebulizer body 1 exploding. The filter 1207 adopts nano-scale filtering material to filter the passing gas, so that the drug molecules remain in the outlet pipe 1205 and are not easy to overflow and affect the environment. Supplementary explanation: the diameter of the pipe mouth at the connection between the outlet pipe 1205 and the single-mouth barrel 1201 is greater than the thickness of the piston plate 1202, so that the piston plate 1202 will not completely block the outlet pipe 1205 during the movement, which is convenient for the smooth movement of the piston plate 1202.

[0033] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
