Abstract
The utility model relates to a self-breaking purifying device for a disposable blood (liquid) transfusion device. The utility model is characterized in that a tapered air channel is adopted, the inlet of the tapered air channel is a tapered bottom, and a one-way valve composed of a steel ball and a tubular plunger whose end face is an inner concave sphere is arranged in the tapered air channel. The inlet of the tapered air channel is provided with a paper medical filtering net whose periphery is fixed to an annular filtering net bracket, and the tubular plunger and the annular filtering net bracket are separately fixedly connected with the side wall of the tapered air channel and the end face of the tapered bottom of the tapered air channel. The utility model has the advantages of disposable use and good purifying effect. The tapered air channel can be prevented from forming reflux.
Description
This utility model relates to the transfusion device parts in the medical apparatus and instruments, more particularly, is a kind of disposable blood transfusion (liquid) device purifier.
Disposable use blood transfusion liquid device of the prior art, the purifier on its defeated device head in the air duct only is the Sponge that is placed in the air duct, the obvious deficiency of this frame mode is:
1, Sponge easily comes off or is crooked, causes not reach the purification purpose.
2, the transfusion device head that includes air duct can integral body be reused, and opportunity is provided for illegal person.
3,, form and reflux because air duct is a through type, and externally when reaching, this passage by chance constitutes the return flow line to condition (as infusion bottle and transfusion person's relative altitude).
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and a kind of disposable use, good purification are provided, and can avoid air duct to form the disposable infusion set self-breaking type purifier that refluxes.
The purpose of this utility model is achieved through the following technical solutions.
This utility model adopts the taper air duct, and feeder connection is the awl end, and being provided with by steel ball and end face in the passage is the check valve that the tubular plunger of interior concave spherical surface constitutes.At feeder connection, the medical filter screen of papery is set, the filter screen periphery is fixed in the annular filter screen holder.Described plunger and filter screen holder are connected with air duct sidewall and passage awl bottom face respectively.
Compared with the prior art, this utility model good purification, purification function are reliable; Owing to adopt the papery filter screen, filter screen breaks behind the chance water, realizes from broken, thereby can guarantee once to use; In addition, the setting of check valve in this utility model can stop backflow effectively.
Accompanying drawing is this utility model structural representation.
By the following examples, in conjunction with the accompanying drawings, this utility model is further described.
Embodiment:
Referring to accompanying drawing, on transfusion device head 6, two paths is arranged, the one tunnel is medicine liquid channel 7, another road is an air duct 1.Adopt taper air duct 1, passage 1 inlet is provided with check valve for the awl end in passage 1, check valve constitutes by being placed on steel ball 2 in the passage 1 and the tubular plunger 3 that is connected on passage 1 sidewall, the end face of plunger 3 is interior concave spherical surface, and concave spherical surface and steel ball 2 surfaces coincide in this.At feeder connection, the medical filter screen 4 of papery is set, filter screen 4 peripheries are fixed in the annular filter screen holder 5, and this filter screen holder 5 is connected with passage 1 awl bottom face.
Filter screen that sets gradually in the air duct 1 and check valve are filtered the air that enters in the air duct, and the medicinal liquid in the infusion bottle does not reflux.After once using, the low-quality filter screen is met the water breakage, causes whole of transfusion device head not reuse once more.
Claims (1)
1, disposable use blood transfusion (liquid) device is from broken purifier, it is characterized in that adopting taper air duct (1), passage (1) inlet is the awl end, be provided with in the passage (1) by steel ball (2) and end face is the check valve of tubular plunger (3) formation of interior concave spherical surface, at feeder connection, the medical filter screen of papery (4) is set, and filter screen (4) periphery is fixed in the annular filter screen holder (5), and described plunger (3) and filter screen holder (5) are connected with air duct sidewall and passage awl bottom face respectively.
