Abstract
The invention provides a perfusion device. One end of a tank body, which is between a screen and a sealing cover, is provided with an auxiliary sealing tank body filled with hollow fiber bundles, both ends of the hollow fiber bundles in the auxiliary tank body are fixed on the tank body by sealing openings, the side wall of the auxiliary tank body is provided with two interfaces for charging and discharging liquid, and the two interfaces are arranged on the inner sides of the sealing openings at both ends of the auxiliary tank body respectively. A liquid storage chamber is arranged between the screen at one end of the sealing tank body and the sealing openings of the auxiliary tank body. The sealing tank body and the auxiliary tank body can be separately manufactured and then are in one-piece sealing connection.
Description
Technical field that the present invention belongs to:
The invention belongs to medical apparatus and instruments.
The background of invention technology:
Blood perfusion device is the medical apparatus and instruments that purifies the blood.It realizes that the approach of blood purification is a filling adsorbent resin in the tank body of sealing, tank body is connected in series to guides in the external circulation bloody path, and resin is with the absorption of the toxicant in the blood when tank body for blood flow, and the blood that is cleaned enters body-internal-circulation again.
At present a lot, but common shortcoming is a function singleness at the blood perfusion device product category of different toxicants, promptly only be absorption at toxicant.For some commonly encountered diseases, for example renal failure except needs are got rid of deleterious material, also needs to proceed hemodialysis and gets rid of urine.Operation is pretty troublesome on clinical treatment: finish hemoperfusion earlier, take off the perfusion device, connect also dialysis machine again and dialyse; No. one time Comprehensive Treatment needs 4 to 6 hours.
Summary of the invention:
The objective of the invention is to propose a kind of composite blood perfusion device technical scheme.This is a kind of new type medical equipment that is different from the prior art blood perfusion device, and it has the Comprehensive Treatment function.Technical scheme of the present invention comprises the interface that can connect bloody path on the seal cover at tank body, tank body two ends of sealing, in the hermetically sealed can in dress adsorbent resin, the sealed at both ends lid and between the adsorbent resin screen cloth that prevents resin wear is arranged, the sealing pair tank body of dress hollow fiber bundle described sealed shell of tank one end also has one section between screen cloth and seal cover in, auxiliary tank body inner hollow fibre bundle two ends are fixed with seal and tank body, offer two interfaces of turnover liquid on the auxiliary tank body sidewall, two interfaces lay respectively at sealed at both ends mouthful of inboard of auxiliary tank body.Between the screen cloth of sealed shell of tank one end and the seal of auxiliary tank body fluid storage compartment is arranged.Sealed shell of tank and auxiliary tank body can be split production then one be tightly connected.
Embodiments of the invention
Embodiments of the invention are as shown in drawings:
Accompanying drawing is one embodiment of the present invention.Label among the figure is represented respectively: 1, blood perfusion device tank body, 2, the bloody path interface 2.1 of seal cover, 2.2,3, resin packing space A, 4, screen cloth, 5, auxiliary tank body, 6, hollow fiber bundle space B, 7, the hollow fiber bundle sealed end, 8, auxiliary tank body liquid entrance 8.1,8.2,9, the fluid storage compartment between resin container screen cloth 4 and the auxiliary tank body hollow fiber bundle sealed end 7.
In conjunction with example figure the present invention is specified:
The present invention is the sealing pair tank body 5 of dress hollow fiber bundle B also have a section between the screen cloth 4 of blood perfusion device tank body 1 one ends of prior art loaded resin A and seal cover 2.2 in, auxiliary tank body 5 inner hollow fibre bundle B two ends are fixed with seal 7 and tank body, on auxiliary tank body 5 sidewalls, offer two interfaces 8.1 of turnover liquid, 8.2, two interfaces lay respectively at auxiliary tank body 5 sealed at both ends mouthfuls 7.1,7.2 inner space 6 positions are with the gap formation path of fibre bundle B.Have between the screen cloth of sealed shell of tank one end and the seal of auxiliary tank body.Sealed shell of tank 1 and auxiliary tank body 5 can be split production then one be tightly connected.
The present invention has improved the tank structure of prior art blood perfusion device, with two kinds of different treatment function synthesizeds of hemoperfusion and hemodialysis technology in a medical apparatus and instruments.
The present invention is blood to be imported and exported 2.1,2.2 be connected in series in the external bloody path specific to the using method of treatment renal failure, and import 2.1 connects the bloody path upstream, and outlet 2.2 connects the bloody path downstream; Blood is entering the space 3 of flowing through earlier in the composite tanks of the present invention through import 2.1, and the toxicant in the blood is adsorbed by Resin A; Be flowed to fluid storage compartment 9 then, enter in the fibre bundle of space 6 parts of auxiliary tank body 5 by the intensive hollow fiber cavity in seal 7.1 places again, realize the dialysis function; Fiber mouth by seal 7.2 places confluxes again, enters bloody path through seal cover bloody path outlet 2.2; Dialysis solution on the auxiliary tank body imports and exports 8.1,8.2, and with the gap formation dialysis solution path of fibre bundle, dialysis solution can be taked the concurrent form, and then mouth 8.1 is import, and mouth 8.2 is for exporting; Also can take the reverse flow form, then mouth 8.2 is import, and mouth 8.1 is outlet.
The present invention can realize hemoperfusion and hemodialysis simultaneously in once-through operation.The clinical treatment operation is simplified, and treatment time can shorten half.Both reduce the treatment cost, improved operation efficient, alleviated patient's misery again.
Claims (3)
1, a kind of composite blood perfusion device that is used for blood purification, the tank body that comprises sealing, the interface that can connect bloody path is arranged on the seal cover at tank body two ends, dress adsorbent resin in the hermetically sealed can, in the sealed at both ends lid and between the adsorbent resin screen cloth that prevents resin wear is arranged, it is characterized in that described sealed shell of tank one end between screen cloth and seal cover, also have one section in the sealing pair tank body of dress hollow fiber bundle, auxiliary tank body inner hollow fibre bundle two ends are fixed with seal and tank body, offer two interfaces of turnover liquid on the auxiliary tank body sidewall, two interfaces lay respectively at sealed at both ends mouthful of inboard of auxiliary tank body.
2, composite blood perfusion device as claimed in claim 1 is characterized in that between the seal of the screen cloth of sealed shell of tank one end and auxiliary tank body fluid storage compartment being arranged.
