Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole realities
Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model mainly includes knee joint cavity and punctures and drain connectivity kit (schematic diagram 1), disposable knee joint cavity
Puncture and rinse bag (schematic diagram 2), the needle point of puncture needle 10 is needle pattern, has spike drift angle 20, and spike drift angle 20 has angle
α, α are preferably 60 °≤α≤90 °, and inserting needle is easy, can mitigate pain when patient punctures, in addition, puncture needle 10 is substantially disjunctor
Liquid in-out crosspointer road (feed liquor needle track 1 and go out liquid needle track 2) composition, both independently of each other but turn into an entirety, this disjunctor
Design, integrate liquid in-out needle track, avoids the secondary puncture of articular cavity, in schematic diagram 1 interval 5 be liquid in-out needle track every
From region, two-way adapter 8 is hose design, and comprising two interfaces 7, side connects the first syringe 3 or adjustable by interface 7
Negative pressure drainage device (not shown), the draining hole 19 that opposite side connects out liquid needle track 2 design, and the draining hole 19 design is located at
2/3rds positions of puncture needle 10, aid in determining whether knee joint cavity puncture depth, inlet 6 connect the second syringe 4 or
Adjustable pressurization power set.
Referring to schematic diagram 2, the present embodiment also includes disposable normal saline flushing liquid 9, is designed for inner wrapping, is easy to protect
Deposit, and do not waste, the present embodiment also includes the 3rd syringe 18 and standby syringe needle 14, can be noted by inlet 6 into articular cavity
Penetrate medicine such as (sodium hyaluronate, traditional Chinese medicine injection, composite ozone, Platelet-rich plasm, compound betamethasone injection), hemostasis
Patch 11 is used for the hemostasis of site of puncture, and gauze 17, elastoplast 12 locally add available for the knee joint of-flushing-after draining is drained
Briquetting is pricked, and sterilized cotton ball 13, cleaning brush 16 are used for the sterilization of knee joint cavity site of puncture, and puncture needle 10 is the He of feed liquor needle track 1
Go out the disjunctor design of liquid needle track 2, designed in packing box 15 for variously-shaped groove, puncture and rinse for accommodating knee joint cavity
Each accessory of device.
Operation principle：Point of puncture is the outer upper limb of kneecap, and the distribution of this regional nerve is few, feels insensitive, pain subtracts, knee joint
The whole process that chamber punctures should observe sterile working principle, first, open disposable knee joint cavity and puncture and rinse bag, cleaning brush 16 dips in
ANER DIAN sterilization kneecap outer upper limb 2-3 times, puncture needle 10, which is given, to be punctured, and patient lies supine position, knee joint stretches, at the outer upper limb of kneecap
With musculus vastus lateralis intersection, oblique patellofemoral joint center, vertical skin, which punctures, enters articular cavity, punctures and is preferably omited in case of bone stops
The withdraw of the needle is a little and slightly changes puncture direction, and the depth of puncture is assessed by the tongue of puncture needle liquid outlet, can after puncturing successfully
