Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly to an orbital sampler. Background Art

[0002] In current medical practice, orbital drug administration and sampling are common operations in ophthalmology and related fields. However, traditional operation methods have significant limitations. Firstly, traditional methods usually require the use of a syringe and a sampler for drug administration and sampling respectively, which requires medical staff to insert the instruments into the patient's orbit multiple times. This not only makes the operation cumbersome, but also the repeated insertion and extraction will bring unnecessary pain and discomfort to the patient. Secondly, since the syringe and the sampler usually directly perform injection and sampling, the distribution and collection of the liquid medicine or sample in the orbit often concentrate at one point, which may cause direct impact on sensitive tissues in the orbit and affect the representativeness and accuracy of sampling. Summary of the Invention

[0003] The purpose of the utility model is to provide an orbital sampler aiming at the problems existing in the prior art, which reduces the number of insertions and extractions, simplifies the operation steps, improves work efficiency, reduces the patient's pain and improves sampling accuracy.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An orbital sampler, comprising: a sleeve assembly, including a sleeve and a first interface seat connected to the sleeve, and a plurality of side holes are provided on the front side wall of the sleeve; a drug administration assembly, including a syringe and a second interface seat connected to the syringe, the syringe can pass through the first interface seat and be inserted into the inner cavity of the sleeve, and the second interface seat cooperates with the first interface seat to realize the positioning of the syringe; a sampling assembly, including a needle rod and a third interface seat connected to the needle rod, the needle rod can pass through the first interface seat and be inserted into the inner cavity of the sleeve, and the third interface seat cooperates with the first interface seat to realize the positioning of the needle rod.

[0006] A water-absorbing needle core is provided at the front end of the needle rod. When the needle rod is inserted into the sleeve, the third interface seat cooperates with the first interface seat to make the water-absorbing needle core located in the area where the side holes are located.

[0007] A piston is sleeved at the front end of the syringe. The piston is used for sealing and sliding cooperation with the inner wall of the sleeve. When the syringe administers drugs, the piston is located behind the area where the side holes are located. When the syringe is completely inserted into the sleeve, the piston covers all the side holes.

[0008] The front end of the second interface base is provided with a plug post, and the rear end of the first interface base is provided with a slot for mating and plugging with the plug post; a rib is provided on the side wall of the plug post, and a guide groove for mating with the rib is provided on the side wall of the slot. When the rib is aligned with the guide groove, the plug post can be inserted into the slot.

[0009] The front end of the sleeve is a dome.

[0010] Flank plates are provided on both sides of the first interface base and the third interface base for finger holding.

[0011] The second interface base is also used to connect a syringe, and the syringe needle tube introduces the liquid medicine of the syringe into the sleeve, so that the liquid medicine is pressurized and enters the eye socket through the side holes.

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

[0013] In the traditional method, medical staff need to use a syringe and a sampler to administer medicine and take samples respectively, which requires entering the eye socket twice. The operation is relatively cumbersome, and repeated plugging and unplugging will bring unnecessary pain and discomfort to the patient; while in this embodiment, only one sleeve is inserted into the eye socket, and then the medicine administration component and the sampling component are respectively matched with the sleeve to administer medicine and take samples. Medical staff do not need to replace the sleeve between medicine administration and sampling, which can reduce the number of plugging and unplugging times, simplify the operation steps, improve work efficiency, and reduce the pain of the patient;

[0014] In the traditional method, the syringe and the sampler are usually directly used for injection and sampling; while in this embodiment, medicine is administered and samples are taken through multiple side holes on the side wall of the sleeve, so that the medicine or sample is more widely dispersed or collected in the eye socket instead of concentrating at one point. This can not only reduce the direct impact on sensitive tissues in the eye socket when injecting liquid medicine, but also improve the representativeness and accuracy of sampling.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] Such as Figures 1 to 5As shown in the figure, an orbital sampler includes: a cannula assembly, including a cannula 1 and a first interface seat 2 connected to the cannula 1. A plurality of side holes 3 are provided on the front side wall of the cannula 1; a drug delivery assembly, including a syringe 4 and a second interface seat 5 connected to the syringe 4. The syringe 4 can pass through the first interface seat 2 and be inserted into the inner cavity of the cannula 1. The second interface seat 5 cooperates with the first interface seat 2 to realize the positioning of the syringe 4; a sampling assembly, including a needle rod 6 and a third interface seat 7 connected to the needle rod. The needle rod 6 can pass through the first interface seat 2 and be inserted into the inner cavity of the cannula 1. The third interface seat 7 cooperates with the first interface seat 2 to realize the positioning of the needle rod 6.

[0026] Specifically, during the sampling operation, hold the first interface seat 2, align the front end of the cannula 1 with the patient's orbit, and then insert the cannula 1 into the orbit until it reaches around the orbital connective tissue; then insert the syringe 4 through the first interface seat 2 and into the inner cavity of the cannula 1, and slowly inject the required liquid medicine into the orbit through the side holes 3. After the injection is completed, slowly withdraw the syringe 4; then insert the needle rod 6 through the first interface seat 2 and into the inner cavity of the cannula 1. The liquid in the orbit enters the cannula 1 through the side holes 3 and contacts the needle rod 6, and the needle rod 6 sucks the sample liquid; finally, withdraw the needle rod 6 from the orbit, immediately transfer it to an appropriate container, and process it according to laboratory procedures.

[0027] Specifically, the required liquid medicine can be sterile normal saline. As a pretreatment liquid before sampling, normal saline can make the sample easier to collect.

[0028] In the traditional method, medical staff need to use a syringe and a sampler to administer medicine and sample respectively, which requires entering the orbit twice. The operation is relatively cumbersome, and repeated insertion and extraction will cause unnecessary pain and discomfort to the patient; in this embodiment, a cannula is inserted into the orbit, and then the drug delivery assembly and the sampling assembly are respectively cooperated with the cannula to administer medicine and sample. Medical staff do not need to replace the cannula between drug administration and sampling, which can reduce the number of insertions and extractions, simplify the operation steps, improve work efficiency, and reduce the patient's pain and improve the patient's comfort.

[0029] In the traditional method, a syringe and a sampler are usually used for direct injection and sampling; in this embodiment, medicine is administered and samples are taken through a plurality of side holes 3 on the side wall of the cannula, so that the drug or sample is more widely dispersed or collected in the orbit, rather than concentrated at one point. This can not only reduce the direct impact on sensitive tissues in the orbit when injecting the liquid medicine, but also improve the representativeness and accuracy of sampling.

[0030] In some embodiments, a water-absorbing needle core 8 is provided at the front end of the needle rod 6. When the needle rod 6 is inserted into the cannula 1, the third interface seat 7 cooperates with the first interface seat 2 to make the water-absorbing needle core 8 located in the area where the side holes 3 are located.

[0031] Preferably, the water-absorbable core 8 is made of medical PVA (polyvinyl alcohol) material, which has good biocompatibility and water absorption performance. Through the precise fit of the interface seat, the water-absorbable core 8 can accurately align with the side holes 3, so as to ensure that the sample liquid can be accurately sampled from the side holes 3, improving the accuracy of the operation.

[0032] In some embodiments, a piston 9 is sleeved on the front end of the syringe barrel 4. The piston 9 is used for sealing sliding fit with the inner wall of the sleeve 1. When the syringe barrel 4 administers medicine, the piston 9 is located behind the area where the side holes 3 are located. When the syringe barrel 4 is completely inserted into the sleeve 1, the piston 9 covers all the side holes 3.

[0033] Specifically, when the syringe barrel 4 injects the liquid medicine, the piston 9 is located behind the area where the side holes 3 are located, so that the piston 9 will not block the liquid medicine from entering the eye socket through the side holes 3. After the medicine administration is completed, as the syringe barrel 4 continues to be inserted, the piston 9 moves along with the syringe barrel 4, and the remaining liquid medicine in the sleeve 1 is completely extruded, ensuring that the liquid medicine can be completely and accurately delivered into the eye socket and preventing the liquid medicine from flowing back.

[0034] Furthermore, a plug post 10 is provided at the front end of the second interface seat 5, and a slot for mating and plugging with the plug post 10 is provided at the rear end of the first interface seat 2. A rib 11 is provided on the side wall of the plug post 10, and a guide groove for mating with the rib 11 is provided on the side wall of the slot. When the rib 11 is aligned with the guide groove, the plug post 10 can be inserted into the slot.

[0035] Specifically, through the cooperation of the plug post 10 and the slot, the position of the piston 9 during the medicine administration process can be accurately controlled. When the syringe barrel 4 injects the liquid medicine, the rib 11 is staggered from the guide groove, so that the first interface seat 2 supports the plug post 10, ensuring that the piston 9 is located behind the area where the side holes 3 are located and will not block the liquid medicine from entering the eye socket through the side holes 3. After the medicine administration is completed, by rotating the second interface seat 5 to align the rib 11 with the guide groove, the plug post 10 can be inserted into the slot. During this process, the piston 9 will continue to move forward, thereby completely extruding the remaining liquid medicine in the sleeve 1. This design enables medical staff to control the position of the piston 9 and the delivery of the liquid medicine through a simple rotation action, with simple operation and easy to master.

[0036] In some embodiments, the front end of the sleeve 1 is a dome. The dome-shaped front end of the sleeve can contact and penetrate the eye socket tissue more smoothly, reducing scratches and damage to the surrounding tissues.

[0037] In some embodiments, wing plates are provided on both sides of the first interface seat 2 and the third interface seat 7 for finger holding. The wing plates provide a stable holding point for the operator, enabling more stable control of the first interface seat 2 and the third interface seat 7 during the operation.

[0038] In some embodiments, the second interface base 5 is also used to connect a syringe, and the syringe liquid medicine is introduced into the sleeve 1 through the syringe needle 4, so that the liquid medicine is pressed to enter the eye socket through the side holes 3.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
