Description
Technical field
The invention belongs to the field of medical instrument technology, in particular to a kind of water conservancy diversion support device for liquid medicine filter.
Background technique
The infusion history of the mankind is more and more higher towards infusion accuracy till now, filters out more effective direction
Development.Clinically, it when needing chronic infusion drug, or being transfused the drug of certain special types, requires to use with precision
The infusion apparatus of liquid medicine filter.Precision liquid medicine filter is the bleeding for needing to participate in infusion apparatus, if filter interior
Structure is inappropriate, it is easy to cause internal hiding bubble or bubble to be discharged in infusion process, follow with medical fluid flow velocity blood of human body
Loop system has potential damage to human body.Applicant applied on July 6th, 2017 a kind of liquid medicine filter (application number:
201720811326.1) utility model patent discloses a kind of double membrane filters, including upper cover 2, filter membrane 2, passes through increasing
Big filter membrane area solves the problems, such as that the existing larger medical fluid of filter infusion concentration is easy to produce blocking.The utility model patent is also
A kind of technical solution for being not easy to hide bubble, including a water conservancy diversion and supporting mechanism are disclosed, water conservancy diversion and supporting mechanism are to pass through
No less than one supporting rib and a plane being connected with pedestal composition；2 upper covers have water conservancy diversion close to the place of liquid outlet
Column；Guide functions can be played to medical fluid, reduce the probability that bubble is concealed.
The laboratory proofing technical solution, although the technical solution, which compares prior art, can solve to block substantially and hide
The problem of bubble, but portion is still easy to conceal bubble in liquid medicine filter, and compares conventional art and be less susceptible to be discharged.
Summary of the invention
The purpose of the present invention is to provide the water conservancy diversion support device for liquid medicine filter, solves part in the prior art and tie
Structure is easy hiding bubble, and is not easy the problem of being discharged.
In order to reach the goals above, it is adopted the technical scheme that:
A kind of water conservancy diversion support device for liquid medicine filter, including flow guide bar two, can be straight line or camber line structure, two
The connection of flow guide bar forms an apex angle in liquid medicine filter inlet.It is generally known that liquid medicine filter is divided into epicoele under
Chamber in order to guarantee that gas reaches cavity of resorption prior to medical fluid in exhaust process, and then enters liquid medicine filter lower channel, to arrange
It out outside pipeline, needs for be inverted liquid medicine filter when being usually vented, and upright.Deflector in the prior art does not include this
The flow guide bar of an apex angle is connected into described in invention, it is therefore desirable to be kept upright in exhaust inversion, otherwise, inclined medical fluid mistake
Filter internal poles are also easy to produce the phenomenon that air-liquid mixing.Flow guide bar connects in the present invention, forms one in liquid medicine filter inlet
Apex angle, even if this apex angle can guarantee that liquid medicine filter tilts certain angle, since the intracorporal highest point of chamber is still in liquid out
Mouthful, bubble also can preferentially rise along flow guide bar, until reaching the end of flow guide bar, and break through filter membrane and enter cavity of resorption.
It is described for supporting filter membrane for the water conservancy diversion support device of liquid medicine filter, including support column A and support column B
The diameter of support column B is slightly less than support column A, and slightly higher, therefore when medical fluid enters liquid medicine filter from inlet, can fill first
Full liquid medicine filter epicoele, medical fluid can generate certain pressure to filter membrane, under same pressure, support column B elder generation contact filtration film,
Simultaneously as the area of support column B is smaller, generation pressure is bigger, and liquid can penetrate from there first, forms water droplet in medical fluid mistake
The cohesion of filter cavity of resorption is gradually increasing, and bubble is driven out of from liquid outlet, avoids being initially formed water droplet in liquid medicine filter epicoele, by bubble
It is blocked in intracavitary.Support column A and support column B is uniformly distributed in liquid medicine filter cavity of resorption, pressure of the balance medical fluid to filter membrane.
The present invention also provides a kind of liquid medicine filters with water conservancy diversion support device, including one or more water conservancy diversion branch
Support arrangement, upper cover, pedestal, filter membrane, inlet, liquid outlet put film platform；Upper cover and filter membrane combine to form liquid medicine filter
Epicoele, inlet are located at liquid medicine filter epicoele；Pedestal and filter membrane combine to form liquid medicine filter cavity of resorption, and liquid outlet is located at medicine
Liquid filter cavity of resorption puts film platform on pedestal.
Detailed description of the invention
Fig. 1 is one of the structural schematic diagram of liquid medicine filter of the present invention.Wherein 1, flow guide bar, 2, apex angle, 3, support column A,
4, support column B, 5, put film platform, 6, inlet, 7, liquid outlet.
Specific embodiment
A specific embodiment of the invention is illustrated below with reference to Fig. 1.
One of specific embodiment:
Referring to Fig.1, the water conservancy diversion and support device are located at the middle part of the liquid medicine filter, including two flow guide bars, lead
