Description

A kind of sealing blood perfusion apparatus
Technical field
The present invention relates to technical field of medical instruments, specifically, relate to a kind of perfusion device for blood purification.
Background technology
Hemoperfusion is the blood purification technology that rapid of emerging is new clinically in recent years, and treatment category has related to nephropathy, acute poisoning, hepatopathy, critical illness, dermatosis and immune disease etc.As the medical apparatus and instruments being exclusively used in blood purification, a kind ofly seal in blood perfusion apparatus the adsorbent that placed and purify the blood, be arranged on during use in the bloody path of extracorporeal circulation, blood passes through wherein, and target substance is trapped in perfusion device by adsorbent and blood is purified.
Chinese invention patent CN200820047979 discloses a kind of single use one sealing blood perfusion apparatus, and as Fig. 1, the component parts of this perfusion device comprises an adhesive layer 7 and two cover sealings place 8 for sealing the axial two-port of adhesive layer 7 respectively.In adhesive layer 7 in pipe, various types of adsorbent can be installed according to different therapeutic purposes, such as immunoadsorbent, acticarbon, resin sorbent etc.As Fig. 2 and Fig. 3, often overlap sealing place 8 and be made up of screen casing 6, sealing plain cushion 5, lid 4, screw 3 and medicated cap 1 etc.Wherein, adhesive layer 7, lid 4, screw 3 and medicated cap 1 all adopt medical Merlon (PC) to produce with Shooting Technique as raw material; Sealing plain cushion 5 and the sealed bolster 2 be fixed on medicated cap 1 all adopt silicone rubber to produce with Shooting Technique as raw material; Screen casing 6 is normally produced with weaving manner as raw material with nylon yarn.
As Fig. 2 and Fig. 3, the adhesive layer 7 of perfusion device has the form of cylinder 701, the interior pipe hollow of this cylinder 701, and this hollow space forms the filter chamber 705 for holding granular adsorbent and so on material.A column butt joint ring radially expanded 702,703 is respectively arranged with at axis two tops of cylinder 701.The outer peripheral face of column butt joint ring 702,703 is respectively arranged with external screw thread 704 outstanding outwardly.Screen casing 6 obtains by fix nylon knitmesh 602 with chemical adhesive, melting or ultra-sonic welded mode in annular framework 601 after.Sealing plain cushion 5 is the annular cushion rubbers adopting silicone rubber to prepare.
As Fig. 2 to Fig. 4, lid 4 is disk and thin plates 401 that shape corresponds to one of axial two tops of adhesive layer 7.On disk and thin plate 401 sidewall 408 vertically, extend the column circular orientation circle 402 coaxial with disk and thin plate 401.In the radial middle position of disk and thin plate 401, be provided with the blood mouth 403 flowed for blood or blood plasma running through disk and thin plate 401.At disk and thin plate 401 vertically back on the sidewall 409 at circular orientation circle 402 place, blood mouth 403 is along the cylindrical docking post 405 of the axial one section of predetermined length that extends outwardly out of disk and thin plate 401.In the radial outer periphery of docking post 405, around a locating dowel 404 coaxial with disk and thin plate 401.The outer post jamb of locating dowel 404 is about in vertebral body form, and its one end near sidewall 409 has larger diameter.The inner wall of locating dowel 404 is cylindrical cavity form.Locating dowel 404 for top with sidewall 409, is stretched out the length approximately identical with docking post 405 along the bearing of trend identical with docking post 405, its inner cylindrical wall is provided with female thread 407.In the radial outer periphery of locating dowel 404, on sidewall 409, be provided with several independently spherical floating-points 406, these spherical floating-points 406 form the annular ring coaxial with disk and thin plate 401 around locating dowel 404.
As Fig. 2 and Fig. 3, screw 3 is the lids with cylindric shirt rim 303, is used on the lid 302 of closed corresponding container at it, is provided with runs through lid 302 and the rounded transitional hole 304 coaxial with screw 3 in its radial medium position.On the inner peripheral surface of shirt rim 303, be provided with female thread 305, so that the knob docking between realizing with the external screw thread 704 of aforementioned adhesive layer 7.
As Fig. 4 to Fig. 6, medicated cap 1 is the lid with column inner ring 105, and its axial one end is in open state, and correspondingly form opening port 107, its opposite end is closed by outer ring 106.Inner at medicated cap 1, extend the cylindrical seal post 103 of hollow along the direction that inner ring 105 is identical from the radial medium position in outer ring 106.The outer peripheral face of sealing column 103 is provided with continuous print external screw thread 104, medicated cap 1 is snapped in locating dowel 404 by the engagement system between external screw thread 104 and aforementioned female thread 407, and under this buckle state, keep locating dowel 404 position radially between inner ring 105 and sealing column 103.Correspond to the aforementioned opening port 107 of medicated cap 1 at inner ring 105 and on the end face radially extended, several location-independent grooves 102 of the axial indent of hats 1 are set.These locating slots 102 form the annular ring coaxial with medicated cap 1 along the circumferencial direction of inner ring 105.Under the state that medicated cap 1 snaps in locating dowel 404, the radial position of locating slot 102 corresponds to spherical floating-point 406, so that the mode being pressed into locating slot 102 by spherical floating-point 406 makes medicated cap 1 be located along the circumferencial direction of locating dowel 404 in locating dowel 404.Like this, when medicated cap 1 is screwed onto in locating dowel 404, because spherical floating-point 406 is pressed into locating slot 102, non-through larger rotating force, the mode be difficult to by reverse convolution comes off from locating dowel 404 by medicated cap 1.Sealed bolster 2 is fixed in the inner chamber 101 of sealing column 103 and close side, outer ring 106 in Interference contact mode.Sealed bolster 2 is the silicone rubber blocks with conical contact block 202 on the axial end middle position of cylindric matrix 201.When sealed bolster 2 is fixed in sealing column 103 inner chamber, the cone point of conical contact block 202 is back to outer ring 106, so that when medicated cap 1 is screwed onto in locating dowel 404, conical contact block 202 envelope is pressed onto on docking post 405, and blood mouth 403 is sealed.
In the one sealing blood perfusion apparatus of said structure, the sealed bolster 2 of the sealing between medicated cap 1 with lid 4 mainly by being encased in medicated cap 1 extrudes the distortion produced mutually with the blood mouth 403 on lid 4 and coordinates.When the locating dowel 404 on medicated cap 1 with lid 4 screws, sealed bolster 2 is close to the port of blood mouth 403, thus reaches the effect of sealing blood mouth 403.There is following drawback in this hermetically-sealed construction:
1) need supporting instrument when turning on medicated cap and use larger strength to open, and each perfusion device product must be equipped with one turns on instrument, add the packaging volume of product thus increase cost, comprising packaging material cost, carrying cost and cost of transportation, cause the wasting of resources.
2) in process of production, because production technology is comparatively complicated, cause portioned product sealing poor effect, add bad product rate, thus add production cost.
3) for the situation needed to injecting fluid in perfusion device, inject again after medicated cap need be turned on, violate the sterile working's principle in blood purification treatment standard operating procedure.
4) sealing means tightening medicated cap is rotated comparatively loaded down with trivial details in process of production, labor intensive and time.
Summary of the invention
