Abstract
The invention discloses a well-hermetic blood perfusion apparatus. A filter layer (4) is disposed between the surface of an apparatus top (2) and the surface of an inner chamber (1). A rubber pad (6) is disposed between the apparatus top (2) and the filter layer (4). The surface of the apparatus top (2) in contact with the rubber pad (6) is provided with two raised waterproof lines (2b). A fastener (5) is fastened to the top end of the inner chamber (1). The edge of the fastener (5) extends to the outer end, forming a protective ring (5b). The inner wall of the fastener (5) is provided with a circular step surface that defines the outer edge of the apparatus top (2) so that the apparatus top (2) compresses onto a tubular port of the inner chamber (1). The apparatus is sealed by fastening, a processing technique is simpler, a production process needs no special equipment, hermetic performance is good, and the processing technique is simpler, reducing processing precision, greatly lowering rejection rate and saving production cost.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of blood perfusion apparatus of good seal.
Background technology
In recent years, blood purification therapy develops rapidly in China and popularizes.Wherein hemoperfusion is one of important way of blood purification.At present, blood perfusion technique is widely used in clinical, not only has good curative effect to serious symptom poisonous substance, drug intoxication, and also can be used for the treatment of many chronic and refractories and difficult disease.Therefore the demand of the blood perfusion apparatus of disposable a kind of good seal increases year by year.
Blood perfusion apparatus, in blood purification process, is connected in the circulation bloody path outside lead body, and when blood flows through tank body, adsorbent is by the toxicant absorption in blood, and the blood be cleaned enters body-internal-circulation again.So sealed type storage after the sterilizing of perfusion device, particularly sterilizing, transport extremely important.In transportation, if perfusion device is poorly sealed, air can be caused to enter the material of filling in perfusion device internal contamination perfusion device, and gnotobasis is destroyed, and content can leak out, and causes perfusion device contaminated equally.
At present, the blood perfusion apparatus produced is that ultra-sonic welded is integrated.This structure, through the production practices of 2 years, adds man-hour permissible accuracy at Making mold very high; Percent defective during injection moulding is higher, and production process needs special equipment, complex process simultaneously, and processing cost is relatively high.
Summary of the invention
Technical problem to be solved by this invention is the blood perfusion apparatus providing the simple a kind of good seal of a kind of manufacture technics.
Technical scheme of the present invention is as follows: a kind of blood perfusion apparatus of good seal, comprise inner chamber (1), machine top (2), end cap (3), filtering layer (4) and securing member (5), its key is: described inner chamber (1) two ends are sealed by a machine top (2) respectively, described machine top (2) central authorities are provided with blood mouth (2a), this blood mouth (2a) is by end cap (3) press seal, filtering layer (4) is provided with between described machine top (2) and inner chamber (1) surface, valve rubber (6) is provided with between this machine top (2) and filtering layer (4), the surface that described machine top (2) contacts with valve rubber (6) is provided with two protruding water-proof wires (2b), described securing member (5) and inner chamber (1) top screw, this securing member (5) edge extends to form guard ring (5b) outward, the step surface that described securing member (5) inwall is provided with annular is spacing to machine top (2) outer edge, machine top (2) is pressed on inner chamber (1) nozzle.
Selecting by screwing, twisting the mode that connects and seal, abandon ultra-sonic welded, manufacture technics is relatively simple, and production process does not need special equipment, greatly reduces percent defective; Press tighter with opportunity top (2) surface that contacts with valve rubber (6) being provided with two protruding water-proof wires (2b), such sealing effectiveness is better, the setting of guard ring (5b) strengthens the intensity of securing member (5), and can erect placement.
Above-mentioned securing member (5) outer circumference surface is axially uniformly distributed fluted (5a).Being to increase friction, facilitating securing member (5) to be tightened on inner chamber (1).
End cap (3) is built with the T-shaped silicagel pad (7) sealing blood mouth (2a) oral area.Blood mouth (2a) and surface are all sealed, forms two-dimensional seal.
Above-mentioned blood mouth (2a) and end cap (3) screw, the upper position corresponding with end cap (3) surface is provided with salient point on the machine top (2) that described blood mouth (2a) is peripheral, and described blood mouth (2a) surface is provided with the groove corresponding with this salient point.After end cap (3) and blood mouth (2a) are tightened, after salient point enters corresponding groove, have and prevent revolution, the effect of being pinned.
Beneficial effect: the present invention adopts to screw and seals, and processing technique is fairly simple, and production process does not need special equipment, favorable sealing property, due to the simplification of processing technique, reduces machining accuracy, greatly reduces percent defective, has saved production cost.
