Abstract
A kind of Micro-Bolt Filter of this utility model, comprise blood inlet, diverter, upper cover, occupying device, drainage screen, housing and blood outlet, described upper tops is provided with air vent, described drainage screen one end is fixed in described diverter, the other end is fixed on described housing bottom, described blood inlet passes through to be connected into blood vessel with described upper cover, described housing bottom center is passed through blood vessel and is connected with described blood outlet, described blood inlet and blood outlet are separately installed with blood inlet protective cap and blood outlet protective cap, described upper cover is connected sealing by sealing ring with bayonet socket with the sealing of housing, do not use any bonding agent, this technical scheme is simple and reasonable can overcome Micro-Bolt Filter exhaust problem in prior art effectively, give the shortcomings such as charge is large, there is good gas, blood separation function, and it is easy to use.
Description
Technical field
This utility model relates to medical instruments field, the Micro-Bolt Filter of micro-bolt and gas in especially a kind of filtering blood.
Background technology
In clinical blood transfusion, transfusion, require to use filter according to national standard, existing filter is generally made up of upper and lower casing and filter membrane purifying layer, filter membrane purifying layer is clipped between upper and lower casing, filtration, purification is carried out to the blood entered and medicinal liquid, and the filtration of the micro-bolt of blood when common filter can not meet open heart operation with extracorporeal circulation.In vitro in circulation cardiac operation under direct vision, blood, can micro-bolt of more than 40um in gas effectively in separating blood and filtering blood by Micro-Bolt Filter, and the generation of reduction Post operation complications, improves the safety of patient.The Micro-Bolt Filter ubiquity used clinically at present aerofluxus and comparatively reliably can not be connected between difficulty and upper and lower casing and cause problems such as patient safety poor performance.
Summary of the invention
In order to solve the problem, this utility model combines the principle of mechanical connection, first connects upper cover and housing by bayonet socket, re-uses sealing ring and make it seal further.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of Micro-Bolt Filter of this utility model, comprise blood inlet 2, diverter 5, upper cover 6, occupying device 8, drainage screen 10, housing 11 and blood outlet 13, described upper cover 6 top is provided with air vent 4, described drainage screen 10 one end is fixed in described diverter 5, the other end is fixed on bottom described housing 11, described blood inlet 2 passes through to be connected into blood vessel 3 with described upper cover 6, described housing 11 bottom centre passes through blood vessel 12 and is connected with described blood outlet 13, described blood inlet 2 and blood outlet 13 are separately installed with blood inlet protective cap 1 and blood outlet protective cap 14, described upper cover 6 is connected sealing by sealing ring 7 with bayonet socket with the sealing of housing 11.
Further, also comprise shunt valve 15, described shunt valve 15 is connected between described blood inlet 2 and blood outlet 13, and described shunt valve 15 is provided with piping clip 16.
Further, described its shape of drainage screen 10 is that double-layer folding formula is cylindric.
By this technical scheme, effectively overcome Micro-Bolt Filter exhaust problem in prior art, give the shortcomings such as charge is large, it is simple and reasonable, smooth in exhaust, good filtration effect, there is good gas, blood separation function, and use more convenient.
