Description

Technical Field

[0001] This utility model belongs to the technical field of sinus treatment tools, specifically relating to a sinus drug releaser. Background Technology

[0002] Sinusitis is a general term for inflammation of the mucous membranes of the maxillary sinuses, ethmoid sinuses, frontal sinuses, and sphenoid sinuses. Clinically, it often coexists with rhinitis and is a common disease in otolaryngology, which can occur singly or in multiple locations. Treatment methods for sinusitis include medication, surgery, and nasal irrigation. Currently, when using medication, it is difficult for drugs to reach the affected sinus sites smoothly due to obstruction from swollen nasal polyps and other nasal tissues.

[0003] To address the aforementioned issues, a utility model patent with publication number (CN209899673U) proposes a self-expanding sinus stent, comprising a support rod and several elastic expansion spokes. A sustained-release drug delivery component is mounted on the support rod. The sustained-release drug delivery component includes a drug reservoir containing symptomatic medication, and the reservoir also has a drug delivery port. The sustained-release drug delivery component further includes a driving component mounted on the support rod, which drives the medication in the drug reservoir to be discharged through the drug delivery port. The elastic expansion spokes have a hollow tubular structure, with one end of each elastic expansion spoke connected to the drug delivery port, and several sustained-release holes are also provided on the sidewall of each elastic expansion spoke.

[0004] The above scheme places the therapeutic liquid inside the drug reservoir and discharges it through the slow-release hole to treat the lesion. The elastic spring allows the elastic expansion spokes to elastically support the inside of the nasal cavity as the swelling of the sinus polyps subsides. At the same time, the elastic spring can drive the drive component to push the liquid out, so that the drug can contact the polyps for treatment, achieving flexible control of the drug release cycle and release amount. However, in actual use, the overall tool is relatively small because it needs to be inserted into the patient's nasal cavity. The medication reservoir in the middle of the tool is even smaller, making it unable to hold a sufficient amount of medication. Furthermore, the amount of medication discharged by the tension spring is insufficient for treatment needs, and subsequent medication addition is impossible, affecting the treatment effect. Simultaneously, the sustained-release orifice directly contacts the sinus polyps, making it prone to blockage by polyp tissue, hindering medication flow. Even if medication does flow out, the lack of a suitable retention structure allows it to easily flow along the expansion spokes to other areas, failing to adequately reach the lesion and further impacting the treatment effect. Additionally, the tool's insertion into the nasal cavity causes significant nasal congestion, exacerbating existing nasal obstruction and resulting in poor efficacy. Therefore, a sinus medication release device is needed to address these issues. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a sinus drug delivery device, which features sufficient drug contact, good therapeutic effect, and strong practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sinus drug release device, comprising a supporting frame, the supporting frame including a connecting rod, a first retaining ring, and a second retaining ring, wherein multiple connecting rods are provided, a first retaining ring is fixed to the top of the connecting rod, a second retaining ring is fixed to the bottom of the connecting rod, and an elastic bracket is movably sleeved on the outer side of the connecting rod, the elastic bracket including a first collar, an elastic frame, a hollow frame, a second collar, and a connecting tube, the first collar being movably sleeved on the outer side of the connecting rod, and the side wall of the first collar being fixedly connected to the elastic frame and the second retaining ring. The system comprises multiple hollow and elastic skeletons, both of which are arc-shaped. The outer wall of the hollow skeleton has a liquid outlet. One end of the hollow skeleton is fixedly connected to a second ring, and one end of the elastic skeleton is fixedly connected to the second ring. The second ring is movably sleeved on the outside of a connecting rod. One end of the hollow skeleton is connected to a connecting pipe that penetrates the side wall of the second ring. One end of the connecting pipe is connected to a liquid storage bladder. The outer side of the hollow skeleton is provided with a contact cotton plate, and the liquid outlet is fitted against the side wall of the contact cotton plate.

[0007] As a preferred technical solution of the sinus drug releaser of this utility model, a first elastic clamp is fixed to one side wall of the contact cotton plate, and a second elastic clamp is fixed to the other side wall of the contact cotton plate. Multiple first and second elastic clamps are provided, and the first and second elastic clamps are symmetrically arranged on both sides of the hollow frame.

[0008] As a preferred technical solution of the sinus drug releaser of this utility model, the contact cotton plate is arc-shaped and made of cotton material.

[0009] As a preferred technical solution of the sinus drug release device of this utility model, the bottom of the reservoir is provided with a conical hole, a conical plug is inserted into the inner side of the conical hole, a connecting band is fixed to the bottom of the conical plug, and a positioning ring is fixed to the outer wall of one end of the conical plug.

[0010] As a preferred technical solution of the sinus drug release device of this utility model, the conical plug is made of elastic material, the positioning ring is located above the conical hole, and the outer ring size of the positioning ring is larger than the top diameter size of the conical hole.

[0011] As a preferred embodiment of the sinus drug releaser of this utility model, the connecting tube is located on one side of the connecting rod, and one end of the connecting tube passes through the second retaining ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, this utility model features a hollow frame and a contact cotton plate. The hollow frame has a liquid outlet hole for the medication to flow out. The contact panel is engaged with one side of the hollow frame. After the entire tool is inserted into the patient's nasal cavity, one side of the contact cotton plate adheres to the patient's sinus polyp, and the other side adheres to the liquid outlet hole. When the medication flows out, it will not flow elsewhere but will soak the contact cotton plate and fully contact the lesion through the contact cotton plate. The large contact area results in a good treatment effect. At the same time, the cotton plate will not block the liquid outlet hole, and the medication will flow out smoothly.

[0014] Furthermore, through the connecting tube and the reservoir, the reservoir is connected to one end of the hollow skeleton. The reservoir is located on the outside of the nasal cavity and can store enough medication for one or two treatments. Patients can squeeze the medication out through the hollow skeleton by pressing the reservoir, which fully meets the medication needs. At the same time, medication can be added later through the conical hole at the bottom of the reservoir without removing the whole tool for medication addition, making the treatment operation convenient. The whole tool can also be removed by pulling the reservoir later, making disassembly convenient.

[0015] In addition, the entire tool is supported by a support frame, which consists of multiple connecting rods and two retaining rings. After the entire tool is inserted into the patient's nasal cavity, the two ends of the support frame are open and the inside is not blocked. After the external elastic bracket opens up the patient's sinus polyps, it can relieve the patient's nasal congestion and is highly practical. Attached Figure Description

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.

[0024] Example 1

[0025] Please see Figure 1-5 The present invention provides the following technical solution: a sinus drug release device, comprising a support frame 1, the support frame 1 comprising a connecting rod 11, a first retaining ring 12 and a second retaining ring 13, the connecting rod 11 having multiple connecting rods, the top of the connecting rod 11 being fixed with the first retaining ring 12 and the bottom of the connecting rod 11 being fixed with the second retaining ring 13, forming a cylindrical shape, the outer side of the connecting rod 11 being movably sleeved with an elastic bracket 2, after the support frame 1 is inserted into the patient's nasal cavity, the patient's nasal cavity is opened by the elastic bracket 2, the middle part of the support frame 1 is in a through state, which can relieve the patient's nasal congestion.

[0026] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the elastic support 2 includes a first ring 21, an elastic skeleton 22, a hollow skeleton 23, a second ring 24, and a connecting tube 25. The first ring 21 is movably sleeved on the outside of the connecting rod 11. The elastic skeleton 22 and the hollow skeleton 23 are fixedly connected to the side wall of the first ring 21. Multiple elastic skeletons 22 and hollow skeletons 23 are provided. Both the elastic skeleton 22 and the hollow skeleton 23 are arc-shaped. When inserted into the patient's nasal cavity, pressing the middle of the two sets of skeletons causes the two rings to move. After being inserted into the nasal cavity, the elastic bulge in the middle of the skeleton supports the polyp at the sinus opening. The skeleton can elastically expand as the polyp subsides. The outer wall of the hollow skeleton 23 is provided with an outlet hole 231. One end of the frame 23 is fixedly connected to a second ring 24, and one end of the elastic skeleton 22 is fixedly connected to the second ring 24. The second ring 24 is movably sleeved on the outside of the connecting rod 11. One end of the hollow skeleton 23 is connected to a connecting tube 25, which passes through the side wall of the second ring 24. The connecting tube 25 is located on one side of the connecting rod 11, and one end of the connecting tube 25 passes through the second retaining ring 13. One end of the connecting tube 25 is connected to a reservoir 3, which is located on the outside of the patient's nasal cavity and has a certain volume to store sufficient medication. The patient can squeeze the reservoir 3 to allow the medication to flow out from the side wall of the hollow skeleton 23 to contact the lesion for treatment, ensuring sufficient medication and treatment effect.

[0027] Reference Figure 3 and Figure 4 As shown, specifically, the bottom of the reservoir 3 is provided with a conical hole 31, and a conical plug 32 is inserted into the inner side of the conical hole 31. A connecting strap 33 is fixed to the bottom of the conical plug 32, and a positioning ring 34 is fixed to the outer wall of one end of the conical plug 32. The conical plug 32 is made of elastic material, and the positioning ring 34 is located above the conical hole 31. The outer circle size of the positioning ring 34 is larger than the top diameter of the conical hole 31. The conical plug 32 can effectively block the conical hole 31. At the same time, the conical hole 31 makes it convenient for medical staff to add medication without having to remove the entire tool for operation, thus improving the convenience of treatment operation. In addition, the reservoir 3 allows medical staff or patients to easily remove the tool inserted into the nasal cavity.

[0028] Example 2

[0029] In another embodiment of this solution, refer to Figure 1 and Figure 5As shown, specifically, the outer side of the hollow skeleton 23 is provided with a contact cotton plate 4, and the liquid outlet 231 is attached to the side wall of the contact cotton plate 4 to effectively absorb the medicine. A first elastic clamp 41 is fixed to one side wall of the contact cotton plate 4, and a second elastic clamp 42 is fixed to the other side wall of the contact cotton plate 4. Multiple first elastic clamps 41 and second elastic clamps 42 are provided, and cotton plates of appropriate width can be selected according to the lesion area. At the same time, the cotton plates can adapt to the deformation of the elastic support 2. The first elastic clamp 4 Both the first and second elastic clamps 42 are symmetrically arranged on both sides of the hollow frame 23. The contact cotton plate 4 is arc-shaped and made of cotton material. In this solution, the cotton material is clamped to the outside of the hollow frame 23, so that one side of the cotton plate is attached to the liquid outlet 231 and the other side is attached to the lesion. When the medicine is discharged, it can soak the cotton plate and make the medicine fully contact the lesion through the cotton plate, avoiding the outflow of medicine, increasing the contact area, improving the treatment effect, and at the same time, it will not cause the lesion to block the liquid outlet 231, which is highly practical.

[0030] The working principle and usage process of this utility model are as follows: When administering medication to a patient's sinuses, a syringe containing medication is inserted into the bottom of the reservoir 3 to inject the medication. After injection, the conical hole 31 is sealed. Then, medical personnel attach the contact cotton plate 4 to the outside of the hollow frame 23. Subsequently, the elastic support 2 is pinched on the supporting frame 1, so that the elastic frame 22 and the hollow frame 23 of the elastic support 2 fit against the supporting frame 1. Then, the entire tool is inserted into the patient's nasal cavity, so that the contact cotton plate 4 corresponds to the lesion side. After reaching the appropriate position, the elastic frame 22 and the hollow frame 23 elastically support the inside of the patient's nasal cavity, so that the contact cotton plate 4 fits against the lesion. Then, the patient can press the reservoir 3 to discharge the internal medication through the outlet hole 231 on the hollow frame 23 and soak the cotton plate. The cotton plate allows the medication to fully contact the lesion for treatment, resulting in sufficient drug contact and good treatment effect. Subsequent medication can be easily added through the conical hole 31.
