[0028] like Figure 1 As shown, it shows a schematic diagram of the structure of the provided anterior chamber puncture kit 1000. An embodiment of the present application provides an anterior chamber puncture kit 1000, which includes a main body 100 and a cover body (not shown in the drawings) disposed above the main body 100, and the main body 100 is configured to include a puncture needle chamber 110 and at least one auxiliary supply chamber. The anterior chamber puncture kit 1000 also includes an anterior chamber puncture needle 200 and at least one auxiliary supply. Among them, the anterior chamber puncture needle 200 is housed in the puncture needle chamber 110, and at least one auxiliary supply is housed in at least one auxiliary supply chamber.

[0029] The anterior chamber puncture kit 1000 provided in the embodiment of the present application accommodates the anterior chamber puncture needle 200 and at least one auxiliary item in the main body 100, which helps to reduce the time for the doctor to prepare various instruments before performing anterior chamber puncture.

[0030] In some embodiments, the anterior chamber puncture kit 1000 may be a disposable item. When stored, the body 100 and the cover of the anterior chamber puncture kit 1000 are sealed as a whole, and the inside of the body 100 may be in a sterile state.

[0031] In some embodiments, the cover can be pivotally connected to the body 100. In some embodiments, the cover can be snap-connected to the body.

[0032] In some embodiments, the puncture needle chamber 110 and at least one auxiliary product chamber in the body 100 can be formed by thermoplastic molding.

[0033] See also Figure 1In some embodiments, at least one auxiliary article includes a liquid collection tube 304, an eyelid opener 305, sterile gauze 306, degreased dry cotton balls 307, and sterile cotton balls 308. In some embodiments, at least one auxiliary article chamber includes a liquid collection tube chamber 122, an eyelid opener chamber 123, a gauze chamber 124, a dry cotton ball chamber 125, and a sterile cotton ball chamber 126. The liquid collection tube chamber 122 is used to store the liquid collection tube 304, the eyelid opener chamber 123 is used to store the eyelid opener 305, the gauze chamber 124 is used to store sterile gauze 306, the dry cotton ball chamber 125 is used to store degreased dry cotton balls 307, and the sterile cotton ball chamber 126 is used to store sterile cotton balls 308.

[0034] See also Figure 1 In some embodiments, the body 100 is divided into a first area 1001 and a second area 1002 along its length direction, and the area of ​​the second area 1002 is larger than that of the first area 1001; the gauze chamber 124, the dry cotton ball chamber 125, the sterilized cotton ball chamber 126, the liquid collecting tube chamber 122 and the eyelid opening chamber 123 are arranged in the first area 1001; and the remaining chambers are arranged in the second area 1002. This arrangement makes it easier for doctors to take corresponding tools when performing anterior chamber puncture.

[0035] In some embodiments, the length of the anterior chamber puncture kit 1000 may be 250 mm and the width may be 200 mm. In some embodiments, the shape of the anterior chamber puncture kit 1000 may be rectangular for easy storage and transportation.

[0036] In some embodiments, the number of anterior chamber puncture needle 200 in anterior chamber puncture kit 1000 may be one, and the anterior chamber puncture needle 200 may be a disposable item.

[0037] like Figure 2 As shown, a schematic diagram of puncturing the anterior chamber 2200 of an eyeball 2000 using the anterior chamber puncture needle in the anterior chamber puncture kit 1000 provided in an embodiment of the present application. In some embodiments, the anterior chamber puncture needle 200 includes a syringe 210 and a pintle 220, the pintle 220 is slidably disposed in the syringe 210 along the axial direction of the syringe 210, and the side wall of the syringe 210 is provided with a slide groove 211 extending along the axial direction of the syringe 210. The anterior chamber puncture needle 200 also includes an operating portion 230, the operating portion 230 is connected to the pintle 220, and the operating portion 230 extends outward from the slide groove 211, and the operating portion 230 is configured to be able to slide along the slide groove 211 under the action of an external force, so as to drive the pintle 220 to slide axially relative to the syringe 210.

[0038] The anterior chamber puncture needle 200 provided in the embodiment of the present application is provided with a slide groove 211 and an operating part 230, so that the doctor can use the thumb of one hand to slowly drive the operating part 230 to slide relative to the slide groove 211 while holding the syringe 210 in one hand. In this way, after the doctor inserts the needle into the patient's anterior chamber 2200, he can operate the anterior chamber puncture needle 200 with one hand to extract aqueous humor from the anterior chamber 2200, and use the other hand to operate the slit lamp microscope to observe the structure of the eyeball.

[0039] When using the anterior chamber puncture needle 200 provided in the embodiment of the present application to draw aqueous humor, the doctor can use the thumb of one hand to apply force to the operating part 230 to slowly drive the operating part 230 to slide relative to the slide groove 211 while holding the syringe 210 in one hand. Since the thumb can more accurately adjust the applied force, it is easier to accurately control the extraction speed and extraction volume, so that the intraocular pressure drops slowly, which is beneficial to maintaining the stability of the anterior chamber 2200 and avoiding damage to intraocular tissues. At the same time, holding the syringe 210 with one hand is more conducive to ensuring the stability of the needle tip and avoiding damage to intraocular tissues such as the corneal endothelium, iris or lens.

[0040] See also Figure 2 In some embodiments, the operating part 230 is located outside the syringe 210. The anterior chamber puncture needle 200 may include a connecting rod, and the operating part 230 is connected to the needle plug 220 through the connecting rod. The operating part 230 may have a disc shape, for example.

[0041] See also Figure 1 In some embodiments, the shape of the puncture needle chamber 110 is substantially rectangular, and a protrusion 111 is formed in the middle of the puncture needle chamber 110 , and the protrusion 111 is used to accommodate the operating part 230 .

[0042] In some embodiments, the side wall of the syringe 210 is provided with scales 212 along the axial direction of the syringe 210 , so that the doctor can accurately control the extraction speed and amount of aqueous humor by observing the scales 212 .

[0043] See also Figure 2 In some embodiments, the anterior chamber puncture needle 200 may further include a needle mounting seat 240, which is disposed at one end of the syringe 210 and is used to mount the needle 260. The end surface of the needle mounting seat 240 facing away from the syringe 210 is a bevel 241. When in use, the maximum distance between the bevel 241 and the syringe 210 is closer to the middle of the cornea, and the minimum distance between the bevel 241 and the syringe 210 is closer to the limbus 2100. It can be seen that the bevel 241 can limit the depth of the needle 260 penetrating into the anterior chamber 2200, which is conducive to fixing the eyeball 2000 and maintaining the stability of the needle 260 in the anterior chamber 2200, reducing the risk of accidentally injuring intraocular tissues.

[0044] See also Figure 2In some embodiments, the angle between the bevel 241 and the cross section of the syringe 210 is 40-50 degrees.

[0045] See also Figure 2 In some embodiments, the maximum distance between the inclined surface 241 and the syringe 210 is located on the same radial side of the syringe 210 as the chute 211. In other words, the maximum distance between the inclined surface 241 and the syringe 210 is the distance between the portion of the inclined surface 241 closest to the center line of the chute 211 and the syringe 210. In other words, the maximum distance between the inclined surface 241 and the syringe 210 and the projection center of the chute 211 in the cross section perpendicular to the syringe 210 are located on the same radius of the cross section of the syringe 210. With this arrangement, when extracting aqueous humor, the inclined surface 241 can be directed downward while the operating portion 230 is directed upward, so that the doctor can use the thumb to operate the operating portion 230 when extracting aqueous humor, so as to better control the extraction speed and amount of aqueous humor.

[0046] In some embodiments, the anterior chamber puncture needle 200 further includes an auxiliary gripping portion 250, which is disposed at the end of the syringe 210 away from the needle mounting seat 240, and is used to assist the doctor in holding the syringe 210. The auxiliary gripping portion 250 is conducive to the doctor being able to hold the syringe 210 more stably with one hand.

[0047] In some embodiments, the auxiliary gripping portion 250 may be two ear-shaped protrusions extending in a direction perpendicular to the axial direction of the syringe 210 .

[0048] See also Figure 2 In some embodiments, the anterior chamber puncture needle 200 may further include a needle 260 and a needle cap 270. The needle 260 is disposed on the needle mounting seat 240; the needle cap 270 is detachably connected to the syringe 210 or the needle mounting seat 240 to cover the needle 260 therein.

[0049] In some embodiments, the end surface of the needle 260 away from the syringe 210 is a bevel to increase the sharpness of the needle 260 and facilitate the needle 260 to penetrate the anterior chamber 2200.

[0050] In some embodiments, the outer diameter of the needle 260 is 0.33 mm, the inner diameter is 0.2 mm, and the length is 5 mm. The outer diameter of the needle in the 1 ml syringe is 0.45 mm, and the inner diameter is 0.25 mm. When the 1 ml syringe is used to perform the anterior chamber 2200 puncture operation, the puncture port is large and the airtightness is poor, which easily causes the puncture port to leak aqueous humor after the anterior chamber puncture. At the same time, the puncture port is directly connected to the outside world, increasing the risk of intraocular infection. The needle 260 of the anterior chamber puncture needle 200 provided in the embodiment of the present application is thinner, the puncture port of the needle 260 is small, the airtightness is good, and the puncture port of the needle 260 is not easy to communicate with the outside world, which can effectively reduce the risk of intraocular infection.

[0051] See also Figure 1 and Figure 2 In some embodiments, the anterior chamber puncture needle 200 may further include a sealing portion 280 , which is disposed at the end of the needle plug 220 located inside the syringe 210 .

[0052] In some embodiments, the sealing portion 280 may be a sealing rubber plug.

[0053] See also Figure 2 In some embodiments, the anterior chamber puncture needle 200 further includes another operating portion 290, which is disposed at the end of the needle plug 220 outside the syringe 210. An extension portion 112 is formed on one end surface of the puncture needle chamber 110 for accommodating the other operating portion 290.

[0054] The operating portion 230 and the other operating portion 290 are respectively received in the raised portion 111 and the extended portion 112 , which helps to prevent the needle plug 220 from sliding along the axial direction of the syringe 210 due to misoperation.

[0055] In some embodiments, the other operating portion 290 may be a tail push handle formed at the end of the pintle 220 .

[0056] See also Figure 1 In some embodiments, at least one auxiliary article may further include a disposable medical cap 301, a disposable mask 302, and disposable gloves 303. In some embodiments, at least one auxiliary article chamber may further include a wear article chamber 121, and the wear article chamber 121 is used to store the disposable medical cap 301, the disposable mask 302, and the disposable gloves 303. The wear article chamber 121 may be disposed in the second area 1002.

[0057] See also Figure 1 In some embodiments, at least one auxiliary product further includes tweezers 309, topical anesthesia eye drops 310, and antibiotic eye drops 311. In some embodiments, at least one auxiliary product chamber further includes a tweezers chamber 127 and an eye drop chamber 128, wherein the tweezers chamber 127 is used to store the tweezers 309, and the eye drop chamber 128 is used to store the topical anesthesia eye drops 310 and antibiotic eye drops 311. The tweezers chamber 127 and the eye drop chamber 128 are disposed in the second area 1002.

[0058] As mentioned above, the instruments or consumables required for anterior chamber puncture are scattered and inconvenient to use. A variety of instruments or consumables are required during anterior chamber puncture, such as sterile cotton balls, sterile gauze, eyelid speculum, eye drops, anterior chamber puncture needles, etc. In daily clinical work, these items are placed in different locations, and they need to be searched and prepared in multiple places before the operation. In addition, it is possible that an item is occasionally missing, which brings inconvenience to clinical operations.

[0059] The anterior chamber puncture kit 1000 provided in the embodiment of the present application stores the anterior chamber puncture needle 200 and the above-mentioned various auxiliary supplies in the main body 100. When preparation for anterior chamber puncture is required, only one set of anterior chamber puncture kit 1000 needs to be prepared, which greatly reduces the time for the doctor to prepare various tools before anterior chamber puncture, and can avoid the inconvenience caused by the lack of a certain item during anterior chamber puncture, which is conducive to improving the efficiency of anterior chamber puncture.

[0060] Ophthalmology clinics are generally not equipped with containers for storing aqueous humor. If aqueous humor specimens need to be transported to a specialized laboratory for testing, there are problems of inconvenience in temporary storage and transportation. Since the anterior chamber puncture kit 1000 of the embodiment of the present application is provided with a liquid collecting tube 304, it can be used to collect aqueous humor specimens and facilitate transportation to a specialized laboratory for testing.

[0061] In some embodiments, the disposable medical cap 301, the disposable mask 302 and the disposable gloves 303 can all be a set. In some embodiments, the disposable medical cap 301, the disposable mask 302 and the disposable gloves 303 can be sealed in the same plastic sealed bag to save space. In some embodiments, the plastic sealed bag sealed with the disposable medical cap 301, the disposable mask 302 and the disposable gloves 303 can be air extracted to compress the plastic sealed bag to further save space.

[0062] In some embodiments, the eyelid speculum 305 in the anterior chamber puncture kit 1000 may be one, and the eyelid speculum 305 may be a disposable item, and may be made by bending a steel wire with a certain elasticity.

[0063] In some embodiments, the sterile cotton ball 308 can be made by fully soaking a dry cotton ball with 0.5% povidone iodine. In some embodiments, the sterile cotton ball 308 can be individually sealed in a plastic sealed bag to prevent the sterile cotton ball 308 from drying and contaminating other items in the anterior chamber puncture kit 1000 during storage or transportation. In some embodiments, there can be multiple sterile cotton balls 308 in the anterior chamber puncture kit 1000, for example, 4.

[0064] In some embodiments, the number of sterile gauze 306 and the number of absorbent dry cotton balls 307 in the anterior chamber puncture kit 1000 can be multiple, for example, the number of sterile gauze 306 can be 4 and the number of absorbent dry cotton balls 307 can be 4.

[0065] In some embodiments, there may be one collection tube 304 in the anterior chamber puncture kit 1000 . The collection tube 304 may be an Eppendorf centrifuge tube with a volume of 0.5 mL.

[0066] In some embodiments, the collection tube 304 can be used to collect aqueous humor. The collection tube chamber 122 is provided to accommodate the collection tube 304 filled with aqueous humor, thereby facilitating temporary storage and transportation of aqueous humor.

[0067] In some embodiments, at least one auxiliary product may further include an information label 312, which may be attached to the outer wall of the liquid collecting tube 304 to indicate the patient information corresponding to the liquid collecting tube 304. In some embodiments, one side of the information label 312 is configured to be writable, so that the doctor can record the patient information on the information label 312; the other side of the information label 312 is provided with an adhesive, so that the information label 312 can be attached to the outer wall of the liquid collecting tube 304. The adhesive may be a self-adhesive sticker.

[0068] In some embodiments, the number of forceps 309 in the anterior chamber puncture kit 1000 may be one, and the forceps 309 may be made of disposable plastic material, which helps to reduce costs.

[0069] In some embodiments, the topical anesthetic eye drops 310 and the antibiotic eye drops 311 in the anterior chamber puncture kit 1000 can both contain 1-2 vials.

[0070] In some embodiments, the topical anesthesia eye drops 310 and the antibiotic eye drops 311 are both small disposable packages made of plastic with a capacity of 0.4 mL, wherein the topical anesthesia eye drops 310 can be 0.5% proparacaine eye drops, and the antibiotic eye drops 311 can be 0.3% levofloxacin eye drops.

[0071] See also Figure 1 In some embodiments, the dry cotton ball chamber 125 and the sterilized cotton ball chamber 126 are arranged along the length direction of the main body 100, and are jointly arranged in the middle of the first area 1001 along the width direction of the main body 100; the liquid collecting tube chamber 122 and the eyelid opening chamber 123 are arranged along the length direction of the main body 100, and are jointly arranged on one side of the first area 1001 along the width direction of the main body 100; the gauze chamber 124 is arranged on one side of the first area 1001 along the width direction of the main body 100, away from the liquid collecting tube chamber 122 and the eyelid opening chamber 123.

[0072] See also Figure 1 In some embodiments, the wearing product chamber 121 is located on the side of the second area 1002 away from the first area 1001; the tweezers chamber 127 and the eye drop chamber 128 are arranged on the side of the second area 1002 close to the first area 1001 along the width direction of the main body 100; the puncture needle chamber 110 is located on one side of the first area 1001 along the width direction of the main body 100.

[0073] The anterior chamber puncture kit 1000 of the embodiment of the present application is advantageous in accommodating more supplies required for anterior chamber puncture in a smaller volume by specially arranging the layout of each auxiliary supply chamber.

[0074] The anterior chamber puncture kit 1000 provided in the embodiment of the present application is complete in supplies and easy to transport and store. It can not only reduce the tedious preparation work of ophthalmologists before the puncture process, but also facilitate the precise and controllable operation of aqueous humor extraction through the anterior chamber puncture needle 200, reduce the risk of intraocular infection after anterior chamber puncture, and has the advantages of safety and convenience.

[0075] The anterior chamber paracentesis kit 1000 of the embodiment of the present application can be used for: collecting aqueous humor samples for testing; temporarily lowering intraocular pressure in glaucoma treatment; and other auxiliary therapeutic anterior chamber paracentesis and drainage.

[0076] Combination Figure 1 and Figure 2 , the operation process of puncturing the anterior chamber 2200 of the eyeball 2000 and collecting aqueous humor using the anterior chamber puncture kit 1000 provided in an embodiment of the present application is described, and the operation process is performed under a slit lamp microscope.

The inclined surface 241 of the needle mounting seat 240 fits with the arc surface of the corneal margin 2100, and the inclined surface of the needle 260 faces the direction of the corneal apex. Adjust the puncture direction of the needle 260 so that the puncture direction of the needle 260 is basically parallel to the plane where the iris 2400 is located to avoid damaging the intraocular structures such as the iris 2400 and the lens 2300.

[0080] The operation part 230 is pushed with the thumb to slowly extract a proper amount of aqueous humor, and the amount of aqueous humor extracted can be read by the scale 212. During the process of extracting aqueous humor, the extraction speed of aqueous humor needs to be controlled with the thumb to slowly reduce the pressure in the anterior chamber 2200, ensuring that the anterior chamber 2200 is always stable during the process of extracting aqueous humor, avoiding sudden drop in intraocular pressure or damage to the intraocular structure by the needle 260.

[0081] After the aqueous humor is extracted, the needle 260 of the anterior chamber puncture needle 200 is pulled out from the anterior chamber 2200. Since the needle 260 is relatively thin, the puncture hole left by the needle 260 can be closed under the elasticity of the cornea. If the aqueous humor needs to be examined later, the aqueous humor can be transferred from the syringe 210 to the collection tube 304 for temporary storage by pushing the operating unit 230 or the operating unit 290. After the aqueous humor is transferred, the corresponding patient information is filled in on the information label 312.

[0082] Antibiotic eye drops 311 are dripped into the conjunctival sac again to prevent infection, and the sterile gauze 306 is taken out to cover and stick to the eyelid skin where the punctured eyeball 2000 is located, completing the anterior chamber 2200 puncture and aqueous humor collection.

[0083] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0084] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be based on the protection scope of the claims.
