Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, in particular to a disposable cotton swab used for anesthetizing the lower opening of the nasolacrimal duct and shrinking the nasal mucosa. Background Art

[0002] Ophthalmic tear duct surgery is mainly divided into dacryocystorhinostomy and laser catheterization. The anesthesia method used is local anesthesia. Lidocaine is used to block the trochlear nerve, infraorbital nerve and anterior ethmoid nerve before surgery. The nasal mucosa at the lower opening of the nasolacrimal duct and the inferior nasal meatus is innervated by the cheek nerve, a branch of the trigeminal nerve. Oxybuprocaine and furane nasal drops are usually used to soak ordinary cotton swabs (straight cotton swabs) and then insert them into the inferior nasal meatus. Because it is difficult for medical staff to control the insertion depth, there is a certain inaccuracy. Ordinary cotton swabs have cotton rods. If they are inserted too deep, it will cause discomfort to the patient. At the same time, when the anesthesia time is long and the effective anesthetic drugs are reduced, ordinary cotton swabs need to be replaced frequently, which may cause secondary damage to the nasal mucosa. For this reason, it is necessary to propose a disposable cotton swab for anesthetizing the lower opening of the nasolacrimal duct and shrinking the nasal mucosa, which can relieve the patient's pain and maximize the anesthesia effect. Utility Model Content

[0003] In order to solve the problem that the above-mentioned anesthetic reduction requires frequent replacement of ordinary cotton swabs, which may cause secondary damage to the nasal mucosa, the purpose of the utility model is to provide a disposable cotton swab for anesthetizing the lower opening of the nasolacrimal duct and shrinking the nasal mucosa. This example can accurately anesthetize the lower opening of the nasolacrimal duct and the nasal mucosa of the inferior nasal meatus, and when the anesthetic drugs are reduced, anesthetic drugs can be injected from the top of the tube body, which can maximize the anesthetic effect and shrink the nasal mucosa, thereby reducing secondary damage and alleviating the patient's pain.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a disposable cotton swab for anesthetizing the lower opening of the nasolacrimal duct and shrinking the nasal mucosa, comprising a cotton strip and a plastic tube body, the cotton strip is located in the tube body and extends to the outside of the bottom end of the tube body, a traction line is glued and connected to the top end of the cotton strip, and a traction assembly for moving the traction line is provided on the traction line, the traction assembly comprises a sphere arranged in the tube body, a through opening is provided on the sphere, a guide wire is fixedly connected to the sphere, the guide wire passes through the tube body and extends to the outside of the top end of the tube body, and the traction line passes through the through opening and extends to the outside of the top end of the tube body.

[0005] The principle of the basic plan is: soak the tampon at the bottom of the tube with anesthetic drugs, and then insert the bottom of the tube into the nasal cavity so that the tampon is located at the lower opening of the nasolacrimal duct. The top of the tampon is attached with a traction line, which pushes the guide wire and the ball to push the tampon out of the tube and fill the nasal passage so that it covers the lower opening of the nasolacrimal duct. Pull out the guide wire and the ball. When the effective anesthetic drugs are reduced, the anesthetic drugs can be injected from the top of the tube to soak the tampon to achieve the effect of secondary anesthesia. When the tampon needs to be removed, the traction line can be pulled to pull the tampon out.

[0006] The beneficial effects of the basic scheme are: 1. Compared with the existing technology, when the anesthesia time is long and the effective anesthetic drugs are reduced, the ordinary cotton swab needs to be replaced, which may cause secondary damage to the nasal mucosa. This scheme can inject anesthetic drugs at the tail end of the tube body, so that the anesthetic drugs soak the cotton strips covering the lower part of the nasolacrimal duct, and ensure the anesthetic effect to the greatest extent, so that the cotton swabs do not need to be replaced frequently, avoiding secondary damage to the nasal mucosa.

[0007] 2. The anesthetic soaked in the cotton swab can anesthetize and shrink the nasal mucosa of the inferior nasal meatus, making it easier to observe the condition of the inferior nasal meatus and making it easier for the surgeon to perform the surgical operation.

[0008] Furthermore, the inner diameter of the tube body is 2.5mm-3.5mm.

[0009] The beneficial effect of the basic solution is: since the size of the tube body 2 is basically the same as the diameter of the human nasal cavity, the diameter of the tube body is more in line with the diameter of the human nasal cavity, which can improve the comfort of the human body. When the cotton swab is inserted into the nasal cavity, it can be easier to find the designated position, reducing damage to the patient's nasal cavity.

[0010] Furthermore, the thickness of the tube body is 0.3mm-0.5mm.

[0011] The beneficial effects of the basic solution are: the appropriate thickness can provide a certain rigidity for the pipe body, reduce material consumption, and save material costs.

[0012] Furthermore, the lower part of the tube body has a curved structure.

[0013] The beneficial effect of the basic scheme is that when the bottom end of the tube is inserted into the nasal cavity, due to the special structure of the human nose, the appropriate curvature can facilitate the injection of corresponding anesthetic drugs when the effective anesthetic drugs are reduced.

[0014] Furthermore, the curvature of the tube body at the bend is between 90 degrees and 170 degrees.

[0015] The beneficial effect of the basic solution is that the ball can pass through the bend smoothly and the problem of the ball blocking the bend of the pipe body is reduced.

[0016] Further, the sphere is located above the bend of the tube.

[0017] The beneficial effect of the basic solution is that, by setting the bending part, the cotton strip and the ball are prevented from falling due to gravity when the tube body is left stationary.

[0018] Furthermore, the diameter of the sphere is the same as the inner diameter of the tube, and the diameter of the sphere opening is 0.6mm-1mm.

[0019] The beneficial effects of the basic solution are: the tampon fills the interior of the tube body, and when the sphere moves, the diameter of the sphere is the same as the diameter of the tube body, which can reduce the leakage of the tampon. The diameter of the through hole is 0.6mm-1mm, and a certain gap can be left around the inner wall of the through hole and between the traction line. While ensuring the traction effect of the traction line, it ensures that the traction line will not be pulled out with the ball when the ball is pulled out of the tube body.

[0020] Furthermore, the cotton strip located at the bottom end of the tube body extends out of the tube body and is in the shape of a cotton cap.

[0021] The beneficial effects of the basic scheme are: the cotton-cap-like structure is basically the same size as the human nasal cavity, the cotton-cap-like structure fits the human nasal cavity better, and the cotton-cap-like structure can increase the absorption area of ​​anesthetic drugs when injecting anesthetic drugs and reduce the overflow of anesthetic drugs. In addition, the cotton-cap-like tampon can cover the outer wall of the bottom end of the tube body. When the bottom end of the tube body is inserted into the nasal cavity, the cotton-cap-like structure contacts the nasal cavity, which can reduce the irritation of the tube body to the nasal cavity and achieve the effect of protecting the nasal mucosa.

[0023] Figure 2 The utility model is a cross-sectional view of a disposable cotton swab used for anesthetizing the lower opening of the nasolacrimal duct and shrinking the nasal mucosa. DETAILED DESCRIPTION

[0024] The following is further described in detail through specific implementation methods:

[0025] The reference numerals in the drawings of the specification include: tampon 1, tube body 2, sphere 3, guide wire 4, traction line 5, and through port 6.

[0026] The embodiment is basically as shown in the attached Figure 1-2 As shown: a disposable cotton swab for anesthetizing the lower opening of the nasolacrimal duct and shrinking the nasal mucosa, comprising a cotton strip 1 and a plastic tube body 2, the inner diameter of the tube body 2 is 2.5mm-3.5mm, and the inner diameter of the tube body 2 in this embodiment is preferably 3mm. Since the diameter of the tube body 2 is basically the same as the diameter of the human nasal cavity, the tube body 2 fits the size of the human nasal cavity, which helps to improve the comfort of the human body. The thickness of the tube body 2 is 0.3mm-0.5mm, and the thickness of the tube body 2 in this embodiment is preferably 0.4mm, so that the appropriate thickness can provide a certain rigidity for the tube body 2, and the lower part of the tube body 2 has a curved structure, and the curvature of the curved part of the tube body 2 is 90 degrees to 170 degrees. In this embodiment, the curvature of the curved part of the tube body 2 is preferably 130 degrees. Due to the special structure of the human nose, the appropriate curvature can facilitate the injection of corresponding anesthetic drugs when the effective anesthetic drugs are reduced.

[0027] The tampon 1 is located in the tube body 2 and extends to the outside of the bottom end of the tube body 2. A traction line 5 is glued and connected to the top of the tampon 1. A traction component for moving the traction line 5 is provided on the traction line 5. The traction component includes a sphere 3 arranged in the tube body 2. A through opening 6 is provided on the sphere 3. A guide wire 4 is glued and connected to the sphere 3. The guide wire 4 passes through the tube body 2 and extends to the outside of the top end of the tube body 2. The traction line 5 passes through the through opening 6 and extends to the outside of the top end of the tube body 2. The sphere 3 is located above the bend of the tube body 2. The tampon 1 is located below the sphere 3. The tampon 1 fills the inside of the tube body 2. The diameter of the sphere 3 is the same as the inner diameter of the tube body 2. When the sphere 3 is pushed, leakage of the tampon 1 can be reduced.

[0028] The diameter of the opening 6 of the sphere 3 is 0.6mm-1mm. In the present embodiment, the diameter of the opening 6 is preferably 0.8mm, so that a certain gap is left between the inner wall of the opening 6 and the traction line 5 to ensure that the traction line 5 will not be pulled out with the sphere 3 when the sphere 3 is pulled out of the tube body 2. The part of the tampon 1 extending outside the bottom end of the tube body 2 is in the shape of a cotton cap. The cotton cap-like structure is basically the same size as the human nasal cavity and fits the human nasal cavity structure better. The cotton cap-like structure can increase the absorption area of ​​anesthetic drugs and reduce the overflow of anesthetic drugs when injecting anesthetic drugs.

[0029] First, soak the tampon 1 with anesthetic, insert the part of the tampon 1 with the cotton cap at the bottom of the tube 2 into the nasal cavity to the lower opening of the nasolacrimal duct, then push the guide wire 4 and the ball 3, and the ball 3 pushes the tampon 1, so that the tampon 1 fills the nasal cavity and covers the lower part of the nasolacrimal duct, then pull out the guide wire 4 and the ball 3, leaving the tube 2 and the tampon 1 in the nasal cavity.

[0030] When the anesthetic drug is reduced and needs to be injected, the anesthetic drug is injected from the top of the tube body 2, and the anesthetic drug flows along the tube body to the tampon 1 and soaks the tampon 1, thereby achieving the effect of replenishing the anesthetic drug. If the tube body 2 is no longer needed, the tube body 2, the tampon 1 and the traction line 5 can be directly pulled out as a whole. If the nasal cavity needs to be closed for a long time, the tube body 2 can be directly taken out, and then the tampon 1 and the traction line 5 can be left in the nasal cavity. When the tampon 1 needs to be taken out, the traction line 5 is directly pulled to pull out the tampon 1.

[0031] When the effective anesthetic drug is reduced, the anesthetic drug can be injected into the soaked cotton strip 1 through the tube body 2 to achieve the anesthetic effect. There is no need to replace the cotton swab, and no secondary damage will be caused to the nasal cavity, which can help alleviate the patient's pain.
