Abstract
The utility model relates to a multi-passage liquid flowing monitor which comprises a case with four walls and a cover board on the back surface. The multi-passage liquid flowing monitor is characterized in that a valve braking point and a pressure sensing contact point are designed into a whole, the front surface of a support surface is provided with a table surface used for forming the valve braking point and the pressure sensing contact point, a through hole is in the table surface, and the back surface of the support surface is provided with a transverse wall used for forming a liquid flowing passage. The case, the support surface, the table surface and the transverse wall are shaped by one time of injection, and the table surface and a film completely sealing the table surface form the valve braking point and the pressure sensing contact point. The transverse wall on the back surface of the support surface is hermetically connected with the cover board to form the liquid flowing passage, and the case wall is provided with a connection port which outwardly extends and forms an alpha angle with the horizontal position of the front surface of the support surface.
Description
Technical field
This utility model relates to a kind of liquid flow supervising device, particularly a kind ofly is applied in the blood component collection process collection braking fluid path break-make and pressure monitoring is the supervising device of one.
Background technology
It is the main source of medicinal blood that human body is donated blood.When donating blood, often only need certain or certain several specific blood constituent, for example blood plasma, platelet, erythrocyte or leukocyte etc., and other compositions can feed back to the blood donor, to avoid the waste of blood resource.Therefore, donate blood technology in the modern times, adopt the isolating method of blood component collection more, promptly the separation of whole blood of being gathered out by the blood donor becomes different compositions, and the composition that needs is taken out, then remaining component blood is fed back to the blood donor.
At present, there has been the blood that to gather blood constituent to be separated by blood separator, but cooperate the acquisition time and the effect of the disposable utensil of seperator to have nothing in common with each other, monitor mode to fluid path also has difference greatly, and how with the valve braking point separate with the pressure sensing contact point be set to main, make that blood constituent flow process in collection equipment is longer, thus the restriction collecting efficiency.
Summary of the invention
The deficiency of separating the structure existence of setting in view of the valve braking point of present blood component collection utensil employing with the pressure sensing contact point, the purpose of this utility model provides a kind of equipment and a large amount of space and costs of utensil saving that makes blood component collection, and saves the multichannel liquid flow supervising device of acquisition time and raising collecting efficiency.
The multichannel liquid flow supervising device of this utility model, comprise box body with wall and the cover plate that is positioned at the back side, it is characterized in that the horizontal support face that links to each other with wall in the box body is the skeleton of device, the front of supporting surface is useful on the table top that constitutes valve braking point and pressure sensing contact point, through hole is arranged in the table top, be useful on the cross wall that constitutes liquid flow path on the back side of supporting surface, box body, supporting surface, table top and cross wall single injection-molded, table top forms valve braking point and pressure sensing contact point with diaphragm with complete closed around it, cross wall on the back side of supporting surface is connected with cover plate for sealing, form liquid flow path, have respectively on the box wall both sides in opposite directions and stretch out, and become the connectivity port of α angle with the front horizontal level of supporting surface, described α is 0-15 °.
In the above-mentioned multichannel liquid flow supervising device, the table top in the front of supporting surface all adopts ultrasonic bonding or thermosol mode to be connected with the cross wall at the back side of diaphragm, supporting surface with cover plate.
The construction features and the operation principle of critical piece of the present utility model are as follows:
Box body is connected with the cover plate of flexible diaphragm and slab construction respectively with cross wall by the table top on the supporting surface, forms the supervising device that comprises a plurality of valves braking point, pressure sensing contact point and many liquid flow paths.By with the cooperating of dynamical system, the valve braking point is achieved the break-make of controlling liquid path, reaches the automatic control of liquid stream direction; Be positioned at the pressure sensing contact point at supervising device box body two ends, realized pressure monitoring, control the start and stop of respective valve braking point according to the different conditions of individual channel pressure working fluid in the different paths.
This utility model has not only been saved the space because valve braking point and pressure sensing contact point are designed to one, has shortened the blood flow process, and has further improved collecting efficiency.
Description of drawings
Fig. 1 is the transverse cross-sectional view of supervising device of the present utility model.
Fig. 2 is the Facad structure sketch map of no diaphragm-operated supporting surface among Fig. 1.
Fig. 3 is the structure sketch map of supporting surface among Fig. 1.
The specific embodiment
This multichannel liquid flow supervising device is made up of box body 1, cover plate 2 and diaphragm 3, and wherein box body 1 and cover plate 2 are injection mo(u)ldings, and material is a polyesters, as Merlon, lucite etc.; Diaphragm 3 is polrvinyl chloride diaphragms of calendering formation.Connectivity port d1～d10 that the injection mo(u)lding that stretches out is arranged on the box wall 4 and 5, these 10 connectivity ports become 10 degree to tilt with the front horizontal level of supporting surface 6.Cross wall 9 on the back side of supporting surface 6 is realized closed the connection with cover plate 2 by ultrasonic bonding or thermosol mode, has formed and the corresponding L1 that communicates of connectivity port d1～d10～L19 liquid flow path on box wall 4 and 5.A plurality of table tops 7 on the front of supporting surface 6 are realized being connected by ultrasonic bonding or thermosol mode with diaphragm 3, have formed each other independently the valve braking point F1～F10 and the pressure sensing contact point y1～y4 of sealing.
The quantity and the arrangement mode of the valve braking point of supervising device, pressure sensing contact point and liquid flow path can carry out corresponding setting according to the different demands of practical application.
The above description of being done in conjunction with this utility model embodiment does not constitute any qualification to protection domain of the present utility model.Those skilled in the art can make various changes on basis of the present utility model, these change all should think and fall within the protection domain that this utility model claim limited.
