Abstract
The utility model relates to a paracentesis sheath, which occludes paracentesis hole depending on magnetic attraction. The utility model comprises a scabbard body (8) in the middle and a scabbard tube in the lower portion. One side of the scabbard body is communicated with liquid valve (9), a connector (2) is connected with the scabbard body and an O-shaped packing ring (7) is arranged at coupling part of the two. A pastern hat (1) is positioned on the upper of the coupling part and the pastern hap has hole matched with external diameter of paracentesis needle. The utility model is characterized in that lower portion of the scabbard body has a magnetic cover and a permanent magnet is arranged in the magnetic cover. The bottom of the utility model has a chase (2-1) and an iron channel-flap (5) is attracted in the chase magnetic. Surface of the chase and the iron channel-flap are smooth and occlude through-hole (2-2) of the connector. The utility model has the advantages of simple and skillfully construction, low production costs, convenient and reliable application and longer life.
Description
Technical field
This utility model relates to a kind of abdominal paracentesis apparatus, specifically is a kind of puncture cover that relies on magnetic attraction sealing puncturing hole, and it and puncture needle are used.
Background technology
Abdominal paracentesis cover of the prior art, the reset force of its channel seal sheet adopts spring.This structure one is a relative complex, and sealing and reliability are restricted; The 2nd, can not adapt to the bad working environments of passage for a long time, the life-span is shorter.
Summary of the invention
This utility model technical issues that need to address are, overcome the deficiency of prior art, provide a kind of simple in structure, sealing and reliability height, and long abdominal cavity magnetic puncture cover of life-span.
In the middle of the abdominal cavity of the present utility model magnetic puncture cover sheath body is arranged, the sheath pipe is arranged at the bottom, sheath body one side is communicated with the liquid valve, be connected with joint on the sheath body, both have O-ring seals on the connecting portion, Capsule is arranged at joint top, have on the Capsule and the close-fitting hole of puncture needle external diameter, it is characterized in that described sheath body bottom is with the magnetic lid, is provided with permanent magnet in the lid; The bottom is fluted, and magnetic has the irony capping in the groove, and groove and irony capping have smooth flat, with the through hole sealing of joint.
The seal approach of this utility model key: be the magnetic device to be set give irony capping, seal puncturing hole with magnetic attraction with smooth flat.Smooth flat helps improving sealing.By above measure, can guarantee the seal request that punctures and overlap.
Being provided with of permanent magnet can be the monoblock magnet ring in the magnetic lid, can be the part magnet ring, comprises half magnet ring; But the monoblock magnet ring is even to the suction of irony capping, is unfavorable for the breakthrough that capping is opened, so the general part magnet ring that adopts.No magnet ring part can vacancy, also can all fill with other non-magnetic object, or partially filled.Use proof, it is suitable selecting for use Magnet and aluminium block respectively to become semi-round ring shape, and it is convenient to capping from opening on one side, has considered the center of gravity of puncture cover again.
All there is pit on the two sides of irony capping, and the apparatus (as endoscope) that can effectively avoid having optical mirror plane directly touches the irony capping and causes wearing and tearing, and minute surface is played a protective role.
This utility model simple and ingenious structure, production cost is low, have easy to use and reliable, and long advantage of life-span.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing this utility model is done and to be described in further detail.
Embodiment 1.In the middle of this routine abdominal cavity magnetic puncture cover sheath body 8 is arranged, be connected with joint 2 on the sheath body, both have O-ring seals 7 on the connecting portion.Sheath body one side is communicated with liquid valve 9, and sheath pipe 10 is arranged at the bottom.Capsule 1 is arranged at joint top, has on the Capsule and the close-fitting hole 1-1 of puncture needle external diameter; The bottom is with magnetic lid 3, and permanent magnet 4 respectively becomes semi-round ring shape with aluminium block 6 in the lid.The fluted 2-1 in joint bottom, magnetic has irony capping 5 in the groove, and all there is pit 5-1 on the two sides of capping, and groove and irony capping have smooth flat, with the through hole 2-2 sealing of joint.
After the puncture cover is retained in body cavity, do not having apparatus fashionable from the passage interpolation, capping 5 is attracted to be close to joint 2 by the magnetic force of permanent magnet 4, has realized channel lumen and extraneous sealing.When having apparatus to insert in the passage, apparatus promotes capping 5, and capping 5 is opened by shown position, and operating apparatus can be passed through smoothly.When apparatus was extracted, capping 5 was got back to original position again under magneticaction, seal.
