Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a suction tube structure with suction depth adjustment function. Background Technology

[0002] The nasal cavity is the main respiratory passage for humans. Many upper respiratory tract infections, rhinitis and other diseases can lead to increased nasal secretions, which can affect breathing and nasal treatment.

[0003] Healthy adults can usually clear their nasal secretions themselves to keep their airways clear when they experience increased nasal discharge. However, children or seriously ill or frail patients may not be able to clear their nasal secretions on their own and require assistance from medical staff or family members to keep their nasal passages clear.

[0004] Currently, secretions are often drawn out and treated using negative pressure air. Traditional negative pressure suction catheters have two sets of side holes at the front end. These side holes are used in conjunction with the negative pressure suction catheter to clean secretions deep in the nasal cavity, but they are not ideal for cleaning secretions in the superficial nasal cavity. Furthermore, the deeper the negative pressure suction catheter is inserted, the greater the irritation or damage to the nasal cavity, and the greater the patient's pain. At the same time, the greater the pain, the less cooperative the younger the child will be. Moreover, after the negative pressure suction catheter is inserted into the nasal cavity, the patient's movements can cause the negative pressure suction catheter to move, either going deeper into the nasal cavity or moving backward. Displacement of the front end of the negative pressure suction catheter will reduce its effectiveness.

[0005] Therefore, we propose a suction tube structure with adjustable suction depth. Utility Model Content

[0006] The present invention mainly addresses the technical problems existing in the prior art by providing a suction tube structure with adjustable suction depth.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A suction tube structure with suction depth adjustment function includes a conventional suction tube, wherein the front end of the conventional suction tube is provided with a first front sleeve, and the outside of the first front sleeve is provided with a slidable and adjustable nostril baffle.

[0009] The first anterior cannula includes a first segment and a second segment of different diameters. The first segment extends into the patient's nasal cavity, and the first segment and the second segment are connected.

[0010] The bottom end of the nostril baffle is straight, and the nostril baffle has a through hole inside. A sealing ring is provided on the outside of the through hole. The first section of the first front sleeve is inserted into the through hole, and the sealing ring covers the outside of the first section of the first front sleeve.

[0011] The front side of the nostril baffle is flat, and the rear side of the nostril baffle is provided with a detachable retaining ring. The retaining ring includes a first semicircle and a second semicircle, and the tail ends of the first semicircle and the second semicircle are rotatably connected to each other.

[0012] Preferably, the tail end of the conventional suction tube is connected to the suction device, and the front end of the conventional suction tube is provided with a through side hole.

[0013] Preferably, the diameter of the first segment is smaller than that of the second segment. The first segment is inserted into the patient's nasal cavity, and the front end of the conventional suction catheter is inserted into the hollow cavity of the second segment for locking.

[0014] Preferably, the outer side of the first segment is provided with a scale.

[0015] Preferably, the conventional suction catheter and the first anterior cannula are made of transparent polyvinyl chloride, and the nasal baffle is made of rubber.

[0016] Preferably, the front end of the first semicircle is provided with a slot, and the front end of the second semicircle is provided with a locking strip. When the first semicircle and the second semicircle are closed, the locking strip is inserted into the slot to lock them.

[0017] Preferably, the conventional suction catheter is further provided with a second anterior cannula at its front end. The second anterior cannula includes a first section and a third section with different diameters. The diameter of the first section is smaller than that of the third section. The tail end of the third section is provided with an axially arranged soft strip with gaps between the soft strips. The front end of the third section is provided with a concave tube with an outer diameter smaller than that of the third section.

[0019] Beneficial effects

[0020] This utility model provides a suction tube structure with adjustable suction depth. It possesses the following features:

[0021] Beneficial effects:

[0022] 1. This utility model eliminates the need to replace the structure of a conventional suction catheter, allowing for direct connection and use with a conventional suction catheter, resulting in low operating costs. The structure shortens the length of the suction catheter entering the patient's nasal cavity, and the length can be adjusted according to actual usage, effectively reducing contact between the suction catheter and the nasal cavity, thus reducing irritation during nasal secretion removal and minimizing discomfort for the patient, leading to better patient cooperation. The adjustable nasal suction catheter also reduces the depth of insertion into the nasal cavity, creating a relatively enclosed space for better suction of nasal secretions.

[0023] 2. When adjusting the depth of insertion into the patient's nasal cavity, the nasal baffle is slidably adjusted. The range of movement of the nasal baffle and the length of the front end of the first section are determined according to the scale. After determination, the locking ring is tightened to fix the nasal baffle to the first section. The first section is inserted into the patient's nasal cavity, and the nasal baffle closes the patient's nostrils. The straight edge of the nasal baffle contacts the patient's upper lip, thereby forming a sealed space. The suction device is activated. Because the nasal baffle plays a sealing role, a negative pressure space is formed in the patient's nasal cavity. Phlegm, saliva, pus, blood and other fluids in the nasal cavity are suctioned away from the first section, the second section and the conventional suction tube.

[0024] 3. This utility model can be applied to conventional suction tubes of different diameters. The front end of the conventional suction tube of different diameters is inserted between the concave tube and the third section. At this time, the concave tube is inserted into the inside of the conventional suction tube, and the third section covers the outside of the conventional suction tube. Then, the soft strip is locked and fixed to the conventional suction tube using a retaining ring. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1:

[0036] Please see Figures 1 to 4 As shown, this embodiment provides a suction tube structure with suction depth adjustment function, including a conventional suction tube 1, a first front sleeve 2 at the front end of the conventional suction tube 1, and a slidable and adjustable nostril baffle 3 on the outside of the first front sleeve 2.

[0037] Specifically, the end of the conventional suction tube 1 is connected to the suction device, the conventional suction tube 1 has a through hollow cavity inside, and the front end of the conventional suction tube 1 has a through side hole 11.

[0038] Furthermore, the first anterior cannula 2 includes a first segment 21 and a second segment 22 with different diameters. The first segment 21 extends into the patient's nasal cavity and the first segment 21 and the second segment 22 are connected. The diameter of the first segment 21 is smaller than that of the second segment 22. The first anterior cannula 2 has a through hollow cavity inside. The hollow cavity inside the first segment 21 has the same diameter as the through hollow cavity inside the conventional suction tube 1, and the hollow cavity inside the second segment 22 has the same external diameter as the conventional suction tube 1.

[0039] The front end of the conventional suction tube 1 is inserted into the hollow cavity of the second segment 22 and locked. The front end of the conventional suction tube 1 is in contact with the hollow cavity of the first segment 21. At this time, the conventional suction tube 1 is connected to the first segment 21. The first segment 21 has a scale 211 on the outside.

[0040] Specifically, both the conventional suction catheter 1 and the first anterior cannula 2 are made of transparent polyvinyl chloride (PVC) material. The first anterior cannula 2 is used to suction sputum, saliva, pus, blood and other liquids from the patient's nasal cavity.

[0041] Furthermore, the nostril baffle 3 is made of rubber. The nostril baffle 3 is similar in shape to a semi-circle. The bottom edge of the nostril baffle 3 is straight. The nostril baffle 3 has a through hole 31 inside. A sealing ring 32 is provided on the outside of the through hole 31. The first section 21 of the first front sleeve 2 is inserted into the through hole 31. The sealing ring 32 covers the outside of the first section 21 of the first front sleeve 2.

[0042] The first segment 21 of the first anterior cannula 2 is provided with a scale 211. Since the first anterior cannula 2 is made of transparent polyvinyl chloride, the scale 211 on the nostril baffle 3 can facilitate medical staff to observe the length of the front end of the first segment 21 when it moves.

[0043] Furthermore, the front side of the nostril baffle 3 is flat, and the rear side of the nostril baffle 3 is provided with a detachable retaining ring 4. The retaining ring 4 includes a first semicircle 41 and a second semicircle 42. The tail ends of the first semicircle 41 and the second semicircle 42 are rotatably connected to each other. The front end of the first semicircle 41 is provided with a retaining groove 411, and the front end of the second semicircle 42 is provided with a retaining strip 421.

[0044] After pulling the nostril baffle 3 to the designated position and stopping, close the locking ring 4, insert the locking strip 421 into the locking groove 411, and press the sealing ring 32 with the first semicircle 41 and the second semicircle 42. The sealing ring 32 seals the first section 21 of the first front sleeve 2, thereby fixing the nostril baffle 3 to the first front sleeve 2.

[0045] The working principle of this utility model:

[0046] When in use, with the diameter of the conventional suction tube 1 fixed, the nasal baffle 3, the first anterior sleeve 2 and the conventional suction tube 1 are a set and packaged in a bag during production. Take out the nasal baffle 3 and put it on the first section 21. Adjust the nasal baffle 3 by sliding it according to the required depth to the patient's nasal cavity. Determine the range of movement of the nasal baffle 3 and the length of the front end of the first section 21 according to the scale 211. After determining, lock the retaining ring 4 to fix the nasal baffle 3 to the first section 21. Insert the front end of the conventional suction tube 1 into the second section 22. The tail end of the conventional suction tube 1 is connected to the suction device.

[0047] Insert the first segment 21 into the patient's nasal cavity. The nasal baffle 3 closes the patient's nostrils. The straight edge of the nasal baffle 3 contacts the patient's upper lip, thus forming a sealed space. The suction device is activated. Because the nasal baffle 3 plays a sealing role, a negative pressure space is formed in the patient's nasal cavity. The sputum, saliva, pus, blood and other liquids in the nasal cavity are suctioned away from the first segment 21, the second segment 22 and the conventional suction tube 1.

[0048] When using it, there is no need to insert the first segment 21 too far into the nasal cavity. It only needs to be inserted into the patient's nasal cavity to a short depth. The specific depth can be adjusted according to the actual situation. The nostril baffle 3 blocks the patient's nostrils. Holding the nostril baffle 3 can prevent the suction position from moving during the suction process. At this time, the suction device can be started to complete the suction operation, avoiding damage to the patient's nasal cavity caused by an excessively long suction tube.

[0049] Example 2:

[0050] Please see Figures 1 to 3 and Figure 5 As shown, this embodiment provides a suction tube structure with suction depth adjustment function, and also includes a second front cannula 5. The second front cannula 5 includes a first section 21 and a third section 51 with different diameters. The diameter of the first section 21 is smaller than that of the third section 51. The first section 21 extends into the patient's nasal cavity. The tail end of the third section 51 is provided with an axially arranged soft strip 511. There are gaps between the soft strips 511. The length of the soft strip 511 is about 1 / 2 to 2 / 3 of the length of the third section 51. The front end of the third section 51 is provided with an inner concave tube 52. The outer diameter of the inner concave tube 52 is smaller than the inner diameter of the third section 51. The first section 21, the inner concave tube 52, and the third section 51 are connected.

[0051] The front end of a conventional suction catheter 1 of different diameters is inserted between the concave tube 52 and the third segment 51. At this time, the concave tube 52 is inserted into the interior of the conventional suction catheter 1, and the third segment 51 covers the outside of the conventional suction catheter 1. The side hole 11 at the front end of the conventional suction catheter 1 is covered by the third segment 51 of the unopened soft strip 511. Then, the clasp 4 is used to lock and fix the soft strip 511 to the conventional suction catheter 1.
