Embodiment 1
The present embodiment provides a kind of Portable transfusion apparatus, as shown in Figures 1 and 2 comprising woven hose 1, syringe needle 2, non-return
Mechanism, driving mechanism, pressure regulating mechanism 6, controller, infusion vessel 3, warning device, bandage and shell.
Shell is made of pedestal 42 and upper cover 43, and upper cover 43 is hinged on pedestal 42, and upper cover 43 is enclosed when being fastened with pedestal 42
At an installation space.
Infusion vessel 3 is arranged in the installation space with driving mechanism；One end of woven hose 1 is connected on infusion vessel 3, separately
One end reaches outside installation space after passing through driving mechanism and is connected with syringe needle 2；Non-return mechanism is sealingly disposed in infusion
The junction of pipe 1 other end and syringe needle 2.
As shown in Figures 3 to 5, non-return mechanism includes non-return sleeve 72, annular mounting base 735, non-return component, bias piece
734.Wherein, non-return component includes two pieces of sealing elements 731.
The both ends of non-return sleeve 72 are tightly connected with syringe needle 2 and woven hose 1 respectively, and the lower end of non-return sleeve 72 is in figure
The one end being connect with syringe needle 2, upper end are the one end being connect with woven hose 1；Non-return sleeve 72 has to be connected with syringe needle 2 and woven hose 1
Logical installation cavity 71, installation cavity 71 are preferably cylindrical；Sealing is fixed with annular peace on the internal face of installation cavity 71
Fill seat 735, the inner ring of annular mounting base 735 be liquid in cavity 71 is installed by channel.
Sealing element 731 is two pieces of semicircle plates being mutually matched, whole to be preferably made of silicon rubber, each sealing element
731 arc tips 733 are respectively hinged on the lower end of annular mounting base 735；In the hinge of sealing element 731 and annular mounting base 735
Contact is equipped with bias piece 734, and bias piece 734 is preferably torsional spring, and torsional spring is applied to sealing element 731 towards 72 upper end of non-return sleeve
Pretightning force；Without other outer force effects, only under the action of torsional spring pretightning force, whole two sealing element 731 is in water as shown in Figure 4
Level state, the end face of the flat end 732 of two sealing elements 731 are sealed against each other against while arc tips 733 of two sealing elements 731
Upper surface is sealed against on the lower face of annular mounting base 735, at this time two sealing elements 731 and 735 phase interworking of annular mounting base
The inner ring channel of annular mounting base 735 is blocked in conjunction, i.e., blocks 71 entirety of installation cavity.
In infusion, the liquid in woven hose 1 is flowed along woven hose 1 towards syringe needle 2, and the pressure of liquid can overcome torsional spring
Pretightning force, the flat end 732 of sealing element 731 swings around the hinge joint of sealing element 731 towards 2 direction of syringe needle, two flat ends 732
It is located remotely from each other, while the arc tips 733 of sealing element 731, also far from annular mounting base 735, non-return mechanism is in such as Fig. 3 institutes at this time
Woven hose 1 is connected to by the opening state shown, installation cavity 71 with syringe needle 2, and liquid is flowed by non-return mechanism in syringe needle 2；
When infusion, which is near completion or is infused, have been completed, the liquid pressure in woven hose 1 is reduced even without pressure,
Sealing element 731 resets to horizontality under the action of torsional spring pretightning force at this time, and the inner ring of annular mounting base 735 is blocked, this
When woven hose 1 blocked by non-return mechanism with syringe needle 2, on the one hand outside air can be prevented to enter human vas through woven hose 1
In, on the other hand it can prevent in blood backflow to woven hose 1；When the transfusion part of patient occurs that motion amplitude is excessive, lifts
When spending high the case where causing blood pressure to be higher than liquid pressure, sealing element 731 is pre-tightened in the pressure and torsional spring of draining blood
Horizontality is reset under the action of power, non-return mechanism automatically blocks woven hose 1 and syringe needle 2, prevents blood backflow to infusion
In pipe 1.
