The specific embodiment
Embodiment mono-
(Fig. 2 is the structural representation of 2 tunnel order transfer valves in fact) as depicted in figs. 1 and 2, a kind of multichannel is sequentially switched transfusion device, comprise successively the bottle cork needle 1 that connects, Fei Shi does not drip kettle 3, flow rate regulating valve 4 and venipuncture needle 5, multichannel order transfer valve 6 is between input tube for transfusion 2 and output tube for transfusion 7, and the input pipe joint 12 by its top is connected with input tube for transfusion 2 and output tube for transfusion 7 with following discharge conection 14 respectively, the other end of inputting tube for transfusion 2 and exporting tube for transfusion 7 be connected respectively bottle cork needle 1 and not Fei Shi drip kettle 3; The housing 11 of multichannel order transfer valve 6 is the cavity structure of a side end opening; Housing 11 be provided with below collecting tray 13, collecting tray 13 communicates with output transfusion tube joint 14; In housing 11, be provided with spool 15, a plurality of through holes 18 are distributing on spool 15, the axle center of through hole 18 is intersected with the axle center of spool 15 and is vertical, and position is corresponding with the position of input pipe joint 12, and the axle center of every two adjacent through-holes 18 exists fixing differential seat angle in spool 15 section directions; Open end at housing 11 is provided with stopping means, and stretch out from the opening of housing 11 one end of spool 15.Described limit device structure is the locking nut 16 that is threaded at the excircle of housing 11 open ends, and the limiting stand of the inner surface of locking nut 16 and spool 15 is fitted.In to spool 15 rotary courses, when the axis coinciding of the axle center of through hole 18 and corresponding input pipe joint 12, this road input is connected with output, transfusion liquid flows into collecting tray 13 through corresponding input tube for transfusion 2, input pipe joint 12 and through hole 18, and flows to output tube for transfusion 7 through discharge conection 14.When a special angle, only have a unique road input and output to connect, between two switching positions time, input is disconnected with output.
The profile of described housing 11 is cuboid, its inner chamber is the pyramidal structure that intracavity diameter is less than accent diameter, and spool 15 is the frustum cone structure coordinating with its cavity, and this structure advances spool 15 to move to intracavity by screwing locking nut 16, both are closely cooperated, to guarantee its sealing effectiveness.
Embodiment bis-
(structural representations of Fig. 3 Shi Wei tri-tunnel order transfer valves) as shown in figures 1 and 3, a kind of multichannel is sequentially switched transfusion device, the cavity of described housing 11 is cylinder, spool 15 and housing 11 interference fit in it, open end at housing 11 is provided with stopping means, its structure is for to be provided with boss at housing 11 inner peripherys, and at groove corresponding to the excircle of spool 15, boss and groove form the groove platform structure 19 of mutual fastening.Except said structure, all the other structures are identical with embodiment mono-.
Embodiment tri-
(structural representations of Fig. 4 Shi Wei tri-tunnel order transfer valves) as shown in Figure 1 and Figure 4, a kind of multichannel is sequentially switched transfusion device, the cavity of described housing 11 is the cylinder that two ends communicate, spool 15 and housing 11 matched in clearance in it, between through hole on the excircle of spool 11 between every two through holes and on limit and housing 11 end faces, be respectively equipped with sealing ring, the liquid by sealing ring Dui Mei road seals.One end or two ends at housing 11 are provided with stopping means, and its structure is for being provided with groove at the inner periphery of housing 11, at the excircle of spool 15, are provided with boss corresponding to position, and boss and groove form the groove platform structure 19 of mutual fastening.All the other structures are identical with embodiment mono-.
The position that the initial position of above-mentioned multichannel order transfer valve 6 its spools 15 is always communicated with output in the 1st tunnel input, other road inputs are not communicated with output, after spool 15 rotates to an angle by certain orientation, the 2nd tunnel input is communicated with output, other road inputs are not communicated with output, by that analogy.This multichannel order transfer valve 6 can be designed as the selective uses of plurality of specifications such as 2-8 road.The best commuting angle of the multichannel order transfer valve on 2 tunnels is 90 °, and the best commuting angle of the multichannel order transfer valve on 3 tunnels is 60 °, and the best commuting angle of the multichannel order transfer valve on 4 tunnels is 45 °.Spool 15 can be rotated by rotary knob 17, and the indication indicating according to the switching position arranging on knob 17, can complete transfusion position, Cong Yi road to the switching of another transfusion position, road.
When many bottles of continuous transfusions, the multichannel input tube for transfusion 2 that this multichannel is sequentially switched on transfusion device is connected with corresponding infusion bottle by bottle cork needle 1, the venipuncture needle 5 of the other end is connected with patient's vein, after the 1st bottle of infusion-completed, can manual rotation knob 17 rotate to an angle and switch to the position of the 2nd bottle and continue transfusion, analogize in proper order, thereby realize order between the bottle of many bottles of continuous transfusions, switch.For the situation of many bottles of continuous transfusions, if be used in conjunction with special-purpose automaton, can make whole infusion process without manual intervention, can greatly reduce nurse's dressing change frequency.The 4 bottles of continuous transfusions of take are example, adopt traditional approach, nurse must go to ward 5 times altogether, the operation 5 times of changing dressings, if apply this multichannel, sequentially switch transfusion device and special-purpose automaton, only need prevent or cure a disease room 2 times of nurse, operates 2 times, briefly, can save manpower 60%, nursing efficiency improves greatly, and nurse's labor intensity reduces greatly, and patient satisfaction also significantly improves.
