Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, and in particular to a sprayer for clinical use in respiratory medicine. Background Technology

[0002] Respiratory medicine is a medical specialty that primarily studies, diagnoses, and treats respiratory diseases. The respiratory system includes organs such as the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. In clinical treatment of respiratory diseases, nasal sprayers are a very important therapeutic tool.

[0003] The sprayer, consisting of a syringe and an atomizing nozzle, is a commonly used sprayer in respiratory medicine. Its structure is relatively simple. When using it, you only need to assemble the atomizing nozzle at the syringe nozzle to spray the medicine. However, this type of sprayer has the following drawbacks: when using it, you need to squeeze the syringe piston rod and aim the atomizing nozzle at the affected area. Because more force needs to be squeezed to squeeze the piston rod after adding the atomizing nozzle to squeeze out the medicine, there may be shaking when squeezing. The operation requirements are relatively high.

[0004] Therefore, a sprayer for clinical use in respiratory medicine is proposed. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0009] The piston rod of the syringe is fixedly connected to a rod body inside the housing, and a sliding plate that can slide inside the housing is connected to the side of the sliding plate opposite to the syringe barrel and the housing, and a first spring that always elastically compresses the sliding plate is in contact with it.

[0010] As a preferred embodiment of the respiratory medicine clinical sprayer of this utility model, the bottom of the sliding strip is fixedly connected with a locking tooth, and a toothed plate is slidably disposed inside the housing below the locking tooth for locking the position of the sliding strip by the locking tooth. At least one set of second springs abuts between the bottom of the toothed plate and the housing.

[0011] The bottom of the toothed plate is slidably provided with a slider along its length. Both sides of the slider are fixedly connected with actuating posts. Both sides of the housing are provided with "L"-shaped holes through which the actuating posts can pass. When the actuating post is located at the end of the vertical section of the "L"-shaped hole, the toothed plate can lock the locking teeth. When the actuating post is located at the horizontal section of the "L"-shaped hole, the toothed plate separates from the locking teeth.

[0012] In a preferred embodiment of the respiratory medicine clinical sprayer described in this utility model, both the locking teeth and the toothed plate have ratchet teeth, and the ratchet teeth of the toothed plate face the direction of suction of the syringe piston rod.

[0013] As a preferred embodiment of the respiratory medicine clinical sprayer described in this utility model, wherein: the inner walls on both sides of the housing are provided with arc-shaped grooves that fit the first spring, and the first spring is stuck between the two sets of arc-shaped grooves.

[0014] In a preferred embodiment of the respiratory medicine clinical sprayer described in this utility model, the bottom of the toothed plate is fixedly connected to a slide rail, the slider has a groove matching the slide rail, and the slider is slidably connected to the bottom of the toothed plate through the slide rail.

[0015] In a preferred embodiment of the respiratory medicine clinical sprayer described in this utility model, a positioning post is sleeved on the inner side of the second spring, and the positioning post is fixedly connected to the housing.

[0016] As a preferred embodiment of the respiratory medicine clinical sprayer described in this utility model, an anti-slip pad is also embedded on the outer side of the shell, and the surface of the anti-slip pad is provided with anti-slip texture.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting a first spring, the device can compress the first spring when drawing out the medicine. When spraying medicine, you only need to aim the atomizing nozzle at the affected area, and the first spring will rebound and spray medicine automatically. Compared with the existing technology, this solves the problem that the medicine may shake during spraying and cause it to be unable to be aimed at the affected area.

[0019] 2. The device also features a locking tooth that engages with a toothed plate, which automatically positions the syringe piston rod when drawing out the medication, preventing the spring force of the first spring from being released prematurely.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Reference Figures 1-3 As an embodiment of the present invention, a respiratory medicine clinical sprayer is provided, which includes a housing 1, a syringe 2 fixedly connected to one side of the housing 1, a piston rod of the syringe 2 slidingly passing through the housing 1, and an atomizing nozzle 3 detachably connected to the injection port of the syringe 2.

[0030] The piston rod of the syringe 2 is fixedly connected to a rod body inside the housing 1, and a sliding plate 4 that can slide inside the housing 1 is connected to it. The side of the sliding plate 4 facing away from the syringe barrel of the syringe 2 is in contact with the housing 1, and a first spring 5 is always elastically pressing the sliding plate 4. In use, the atomizing nozzle 3 is removed, the piston rod of the syringe 2 is pulled out, and the medicine is drawn into the syringe 2. When the piston rod moves, it drives the sliding plate 4 to move synchronously. When the sliding plate 4 moves, it presses the first spring 5, causing the first spring 5 to compress and store elastic potential energy. Afterwards, the first spring 5 rebounds and the medicine is sprayed automatically. When spraying medicine, you only need to aim the atomizing nozzle 3 at the affected area.

[0031] like Figure 2 and Figure 3 As shown, a locking tooth 6 is fixedly connected to the bottom of the sliding plate 4, and a toothed plate 7 is slidably disposed inside the housing 1 below the locking tooth 6 for locking the position of the sliding plate 4 through the locking tooth 6. At least one set of second springs 8 abuts between the bottom of the toothed plate 7 and the housing 1.

[0032] A slider 9 is slidably mounted on the bottom of the toothed plate 7 along its length. Actuating posts 10 are fixedly connected to both sides of the slider 9. "L"-shaped holes 1a are provided on both sides of the housing 1, allowing the actuating posts 10 to pass through. When the actuating post 10 is at the end of the vertical section of the "L"-shaped hole 1a, the toothed plate 7 can engage the locking teeth 6. When the actuating post 10 is at the horizontal section of the "L"-shaped hole 1a, the toothed plate 7 separates from the locking teeth 6. When aspirating the medication, the actuating post 10 is moved to the horizontal section of the "L"-shaped hole 1a. At this time, the toothed plate 7 separates from the locking teeth 6, and the sliding strip 4 moves, causing the locking teeth 6 to move. When the appropriate amount of medication is aspirated from the syringe 2, the piston rod is stopped from being pulled. At this time, the first spring 5 has a tendency to rebound, causing the actuating post 10 to... Moved to the vertical section of the "L"-shaped hole 1a, the two sets of 8 drive the actuating column 10 to the end of the vertical section of the "L"-shaped hole 1a. At this time, the toothed plate 7 locks the locking tooth 6, preventing the piston rod of the syringe 2 from moving. The first spring 5 remains compressed. When spraying medicine, aim the atomizing nozzle 3 at the affected area and move the actuating column 10 from the vertical section of the "L"-shaped hole 1a to the horizontal section. When the actuating column 10 moves down, it drives the slider 9 to move down synchronously. The slider 9 drives the toothed plate 7 to separate from the locking tooth 6 through the slide rail 11. At this time, the first spring 5 rebounds, driving the piston rod to move. The medicine is sprayed from the atomizing nozzle 3 to the affected area. This structure is designed to achieve a positioning effect and prevent the medicine from being sprayed out prematurely due to unstable holding by medical staff.

[0033] like Figure 2 As shown, both the locking tooth 6 and the toothed plate 7 have ratchet teeth. The ratchet teeth of the toothed plate 7 face the direction of the piston rod of the syringe 2 for suction. By setting the locking tooth 6 and the toothed plate 7 to ratchet teeth, the device does not need to move the actuating column 10 to the horizontal section of the "L"-shaped hole 1a when suctioning the medicine. The two sets of second springs 8 allow the toothed plate 7 to move elastically downward. Combined with the characteristics of ratchet teeth, the locking tooth 6 can move in one direction. That is, when the locking tooth 6 moves in the direction of piston rod suction, it will be locked by the toothed plate 7 in the opposite direction, which improves the ease of use of the device.

[0034] like Figure 3 As shown, the inner walls on both sides of the housing 1 are provided with arc-shaped grooves that fit the first spring 5. The first spring 5 is stuck between the two sets of arc-shaped grooves. The arc-shaped grooves are used to prevent the first spring from bending non-axially and to play a positioning role.

[0035] like Figure 2 and Figure 3 As shown, a slide rail 11 is fixedly connected to the bottom of the toothed plate 7, and a slide groove matching the slide rail 11 is provided on the slider 9. The slider 9 is slidably connected to the bottom of the toothed plate 7 through the slide rail 11.

[0036] like Figure 2 and Figure 3 As shown, a positioning post 12 is sleeved on the inner side of the second spring 8. The positioning post 12 is fixedly connected to the housing 1. The positioning post 12 is used to prevent the second spring 8 from being misaligned.

[0037] like Figure 1 As shown, an anti-slip pad 13 is also embedded on the outer side of the housing 1. The surface of the anti-slip pad 13 is provided with anti-slip texture. The anti-slip pad 13 is used to prevent the device from slipping during use.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
