Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a nasal aspirator. Background Art

[0002] For example, infants under 3 years old, ordinary people who are elderly or seriously ill, and even some animals that have just been born, usually do not have the ability to discharge nasal secretions on their own. Excessive nasal secretions will block the nostrils and cause breathing difficulties and nasal ulcers. The blocked nostrils will cause nasal secretions to flow back into the lungs and may also cause lung inflammation. Therefore, in order to clear nasal secretions, people invented a nasal aspirator. Traditional nasal aspirators usually include a pipe with an inlet at one end, a liquid storage bottle for storing nasal mucus in the middle of the pipe, and an outlet at the tail end. When in use, negative pressure is formed by pumping air at the outlet, so that the nasal mucus enters the pipe from the inlet and is retained in the liquid storage bottle.

[0003] Current nasal aspirators usually use multiple parts to form multiple chambers, which undoubtedly has the disadvantages of high cost and complicated assembly. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0020] Embodiment 1 of the present invention is a schematic diagram of the packaging state of the nasal aspirator, as shown in FIG. Figure 1 and Figure 3As shown, the nasal aspirator assembly 2 includes a connector 21 and a catheter 22 installed on one side of the connector 21. The connector 21 consists of a first fixing portion 211 connected to the catheter 22 and a second fixing portion 212 coaxially arranged with the first fixing portion 211. The second fixing portion 212 is connected to a negative pressure suction device 3. The connector 21 is used to connect the catheter 22 and the negative pressure suction device 3. The first fixing portion 211 is provided with an adjustment hole 23 perpendicular to the first fixing portion 211 near the connection with the second fixing portion 212. The outer wall of the sleeve 1 is connected with a movable plug 4 near the opening position. The movable plug 4 is installed in the adjustment hole 23 for fixing the nasal aspirator assembly 2. The disposable structure has low production cost, is convenient for single-person use, and is easy to operate. The conical catheter 22 structure is convenient for inserting into the patient's nostrils to quickly absorb and clean up nasal pus.

[0021] The sleeve 1 is a single-sided opening structure of transparent plastic. The sleeve 1 includes a head end 11 close to the opening position and a tail end 12 away from the opening position. The head end 11 is a cylindrical structure and the tail end 12 is a conical structure. The diameter of the sleeve 1 decreases from the head end 11 to the tail end 12. The sleeve 1 provides protection for the nasal aspirator assembly 2 before the nasal aspirator is used to prevent dust and bacteria in the air from contaminating the catheter 22.

[0022] The inner wall of the head end 11 is provided with a raised first clamping strip 13, and at least six groups of the first clamping strips 13 are provided to increase the connection strength between the nasal aspirator assembly 2 and the sleeve 1 to prevent them from falling off.

[0023] The catheter 22 has the same outer contour as the sleeve 1. The catheter 22 is a transparent plastic hose structure. The hose structure protects the patient's nasal cavity and avoids direct contact with the nasal mucosa to cause damage. The transparent structure facilitates observation of the internal situation. A circulation channel 221 is provided in the catheter 22 along the length direction of the catheter 22. Mucus such as snot in the nasal cavity is sucked into the circulation channel 221 by negative pressure and temporarily stored.

[0024] A second clamping strip 211a concentric with the first fixing portion 211 is arranged on the surface of the first fixing portion 211. At least three groups of second clamping strips 211a are arranged. The thickness of the second clamping strip 211a close to the adjustment hole 23 is greater than the thickness of the second clamping strip 211a away from the adjustment hole 23, thereby increasing the connection strength between the connecting piece 21 and the conduit 22 to avoid falling off.

[0025] A trapezoidal anti-drop structure 212 a is provided on the surface of the second fixing portion 212 to increase the connection strength between the connecting member 21 and the negative pressure suction device 3 to prevent them from falling off.

[0026] The negative pressure suction device 3 is a negative pressure airbag, which has low cost. When operated by one person, negative pressure operation can be achieved by manually squeezing the airbag, which reduces the difficulty of operation.

[0027] In the second embodiment of the present application, Figure 2As shown, the difference from the first embodiment is that this embodiment is a schematic diagram of the working state of the nasal aspirator. The nasal aspirator assembly 2 is taken out from the sleeve 1, the movable plug 4 at the head end 11 of the sleeve 1 is installed in the adjustment hole 23, and the negative pressure airbag is installed in the second fixing part 212, and then it can work.

[0028] The working principle of this embodiment is as follows: before using the nasal aspirator, take it out of the package, remove the movable plug in the adjustment hole, take the nasal aspirator assembly out of the sleeve, reinsert the movable plug into the adjustment hole, select a suitable negative pressure suction device according to actual conditions, and when manually operated, install the negative pressure airbag on the second fixed part of the connecting piece, squeeze the airbag manually, insert the catheter into the patient's nasal cavity, and use negative pressure to attract mucus such as nasal discharge into the circulation channel.

[0029] Several points that need to be explained are: First, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, and can be mechanical or electrical connections, or internal connectivity between two elements, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may change; secondly, in this article, relational terms such as first and second, etc. are only used to distinguish one entity from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities.

[0030] The above examples are merely illustrative of the present utility model and do not constitute a limitation on the protection scope of the present utility model. All designs that are identical or similar to the present utility model fall within the protection scope of the present utility model.
