Description
Technical field
This utility model relates to technical field of medical instruments, particularly has the infusion set fixedly holding joint.
Background technology
In clinical treating disease, often give patient infusion or pass through intravenous drip directly by infusion of medicine body.Transfusion bag or infusion bottle are suspended on support, air inlet needle connects trachea, be power by liquid gravity at ambient pressure, air is made to enter infusion bottle from air inlet pipe, air inlet needle, but such structure as power, utilizes atmospheric pressure by liquid gravity, liquid is extruded in transfusion needle, its power is little, can not accurately control transfusion speed and amount of infusion.In transfusion bag or infusion bottle, air enters from air inlet needle from outside, and medicinal liquid is easily polluted.
Current transfusion bag is except above-mentioned defect, transfusion device and transfusion bag are for be connected temporarily, and it is fixed and dismantles is all complete better within fewer time, but existing transfusion device is connected with transfusion bag or expends time in length, connect insecure, causing in an emergency situation cannot fast to patient infusion.Existing transfusion device for clamping, connected mode is single, and operability is low, and connection reliability is low, easily causes transfusion normally to carry out.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provide a kind of structure simple, connect reliable, easy to operate and safety high there is the infusion set fixedly holding joint.
The purpose of this utility model is achieved through the following technical solutions: have the infusion set fixedly holding joint, it comprises conduit, is arranged on the piercing needle of end of conduit, tube for transfusion and is arranged on the valve body of tube for transfusion lower end, piercing needle is through valve body, and be communicated with in tube for transfusion, it also comprises reinforcing coaming plate, claw, flexible element and armature, the cross section of described tube for transfusion is oval structure, reinforce the top that coaming plate is arranged at valve body, reinforce on coaming plate and offer radial upper fastener breach and lower fastener breach; Conduit and piercing needle junction are disposed with upper mounted plate, hollow axle and bottom plate from top to bottom, armature is sleeved on hollow axle, flexible element is vertically installed in the outer rim of armature, and claw is arranged on the upper end of flexible element along the radial direction of armature.
The outside diameter of described valve body is greater than the minor axis of tube for transfusion, and is less than the major axis of tube for transfusion.
The cross section of described flexible element is arc-shaped structure.
Described claw is up-small and down-big trapezium structure.
This utility model has the following advantages:
1, this utility model novel structure, simple, production technology easily realizes, and production cost is low.
2, piercing needle is fixed on the valve body below transfusion bag by catch mechanism, the position relationship between piercing needle and check valve fixed, difficult drop-off, connect reliable.
3, piercing needle is aimed at the check valve below transfusion bag in valve body, upwardly fixed mechanism, catch mechanism is moved along with on fixed mechanism, claw is stuck in draw-in groove, in the process of moving up, body base coordinates with the inclined-plane of claw, when upwardly claw, claw automatically separates towards both sides under the extruding of valve body, workable.
4, the cross section of flexible element is arc-shaped structure, while coordinating with valve outer wall, enhances its intensity, prevents in use flexible element fracture, guarantees that transfusion is normally carried out, improves infusion safety.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional structure schematic diagram in Fig. 1;
In figure: 1-conduit, 2-piercing needle, 3-valve body, 4-tube for transfusion, 5-strengthens coaming plate, 6-bottom plate, 7-upper mounted plate, 8-hollow axle, 9-armature, 10-flexible element, 11-claw, 12-upper fastener breach, 13-lower fastener breach.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, there is the infusion set fixedly holding joint, it comprises conduit 1, is arranged on the piercing needle 2 of conduit 1 end, tube for transfusion 4 and is arranged on the valve body 3 of tube for transfusion 4 lower end, piercing needle 2 is through valve body 3, and be communicated with in tube for transfusion 4, it also comprises reinforcing coaming plate 5, claw 11, flexible element 10 and armature 9, the cross section of described tube for transfusion 4 is oval structure, reinforce the top that coaming plate 5 is arranged at valve body 1, reinforce on coaming plate 5 and offer radial upper fastener breach 12 and lower fastener breach 13; Conduit 1 and piercing needle 2 junction are disposed with upper mounted plate 7, hollow axle 8 and bottom plate 6 from top to bottom, armature 9 is sleeved on hollow axle 8, flexible element 10 is vertically installed in the outer rim of armature 9, and claw 11 is arranged on the upper end of flexible element 10 along the radial direction of armature 9.
Further, as shown in Figure 1, the outside diameter of described valve body 3 is greater than the minor axis of tube for transfusion 4, and is less than the major axis of tube for transfusion 4.
Further, the cross section of described flexible element 10 is arc-shaped structure.
Further, described claw 11 is up-small and down-big trapezium structure.
Work process of the present utility model is as follows: during tube for transfusion 4 connecting puncture needle head 2, piercing needle 2 is aimed at valve body 3 center to puncture, upwardly piercing needle 2, bottom plate 6 promotes armature 9 and moves up, armature 9 drives on claw 11 and moves, claw 11 is up-small and down-big trapezium structure, when the inclined-plane of claw 11 and valve body 3 lower contacts, play guide effect, claw 11 separates to both sides simultaneously, when claw 11 moves to valve body 3 top, under the effect of flexible element 10, claw 11 is drawn in centre, now claw 11 is stuck in upper fastener breach 12, complete conduit 1 and piercing needle 2 is fixed, when transfusion completes, when needing piercing needle 2 to take out, continue upwardly bottom plate 6, claw 11 lower limb is made to exceed the top edge strengthening coaming plate 5, rotate armature 9, flexible element 10 and claw 11 is driven to rotate 90 °, in rotation process, claw 11 clamps all the time with oval tube for transfusion 4, and claw 11 slides in elliptical wall, separate gradually, claw 11 moves to lower fastener breach 13 place, pulls conduit 1 downwards, and upper mounted plate 7 driven rotary plectane 9 moves down, claw 11 exits from lower fastener breach 13, can take out piercing needle 2.
