Embodiment 1

[0066] figure 1 , 2 , 3, 4 show the first embodiment of the present invention. Such as figure 1 , 2 Shown, it is provided with the dish-shaped liquid reservoir 5 of double-eared liquid reservoir fixing part 4 by medical flexible material [especially transparent or translucent flexible material (such as the used material of existing infusion set), is convenient to observe its cavity; of course, it also includes opaque, slightly transparent colloidal material or other medical flexible materials], and its volume is at least equal to the volume of the upper section of the infusion tube (not shown in the figure) (preferably equal to or greater than the entire cavity) The volume of the inner cavity of the infusion tube, this is because it is impossible to completely empty the liquid in the cavity when squeezing it). The pipe plug 2 (funnel-shaped pipe plug, referring to its combination with the short-section conduit below as a funnel, which is the prior art) that is responsibl...

Embodiment 2

[0071] Figure 5 , 6 , 7 show the second embodiment of the present invention. Such as Figure 5 As shown, a kind of tubular needle sinus 14 whose outer mouth can be closed by medical flexible material and can be punctured by an infusion needle and inserted in the cavity can be used as the liquid inlet interface of the liquid reservoir and it is directly arranged on a single-ear-shaped The upper part of the spherical liquid reservoir 17 of the liquid reservoir fixing member 16 is connected to the infusion set in the same way as the connection between the indwelling needle heparin cap and the infusion needle. The lug-shaped reservoir mount 16 is for the attachment of a strap and watch strap-type reservoir mount to allow the bulbous reservoir 17 to be attached to the patient's limb. An infusion tube buckle 15 is sleeved on the outer wall of the tubular needle sinus 14 (it is called an infusion tube buckle because it plays the role of buckling the infusion tube to suspend the l...

Embodiment 3

[0075] Figure 8 , 9 , 10, 11 show the third embodiment of the present invention. Such as Figure 8Shown, the outer wall of its flat tube (cross-section is ellipse) shape liquid reservoir 36 is provided with watchband type liquid reservoir fixture 37. The openable and closable anti-staining type pipe plug 32 that is arranged on the top of the flat tube-shaped liquid reservoir 36 is composed of an infusion extension tube, a switch 33 and a pipe plug 30 [screw plug] that is equipped with a pipe plug cover 29 (button type tube plug cover). (Silk) buckle type pipe bolt] constituted. The tube plug 30 provided with the buckle 31 of the infusion tube can be connected with the end connector of the infusion tube (such as a nipple joint, a hooded joint, a movable hooded joint, etc.). The top of the flat tube-shaped liquid reservoir 36 is indirectly provided with a pipe bolt 35 (screw type pipe bolt, which can also be a funnel-shaped pipe bolt) equipped with a pipe bolt cover 29; ),...

Abstract

The invention discloses a closed-type air remover for a disposable transfusion apparatus / blood transfusion apparatus. On the basis of the phenomenon of liquid holdup on the lower section of the transfusion tube after the dropping funnel is empty, the closed-type air remover is composed of a liquid storage device, wherein the liquid storage device is provided with a liquid storage device inlet port and a liquid storage device outlet port, and the liquid storage device inlet port can be connected with a tail end port of the transfusion tube to receive and store liquid from the transfusion tube cavity. The invention is characterized in that (1) when the dropping funnel is empty and air enters the transfusion tube, the liquid storage device outlet port is firstly closed, and then the liquid storage device body is squeezed, so that the air in the transfusion tube can be squeezed out upwardly, thereby avoiding trouble, waste and port pollution caused when the repetitive separation infusion needle discharges liquid and air downwardly and outwardly, preventing nurses from frequent patrol, and also avoiding professional infections when the blood drops on the port stain the hand of the nurse; (2) the liquid storage device inlet port is firstly closed, and the liquid storage device body is squeezed, so that the residual liquid is input into the human body; the liquid storage device is continuously squeezed, so that the liquid can be dropped and transfused under increased pressure; and the air remover is used for removing air for clinical patients when adding the liquid in the continuous transfusion process.

Description

technical field [0001] The present invention relates to a medical disposable infusion set and an anti-infusion tube air intake (auxiliary) device for a disposable blood transfusion set, in particular to a terminal interface (hereinafter referred to as The terminal interface of the infusion tube, which includes nipple-shaped connectors, cap-type connectors, movable cap-type connectors, etc. Infusion set, disposable blood transfusion set) when the liquid in the dropper cavity is empty and the follow-up liquid is empty, it is not necessary to open (no need to separate) the end interface of the infusion tube and also eliminate the air entering the cavity of the infusion tube. Disposable infusion set, Closed degassing device for disposable blood transfusion set (hereinafter referred to as "closed degassing device for disposable infusion set, blood transfusion set"). Background technique [0002] For a long time, in the preparation of clinical infusion and blood transfusion (refe...
