Abstract

The utility model discloses a convenient operation infusion device. Because the water outlet end of a dropping pipette is provided with a gas holder, and the dropping pipette is bent back upwards and is connected with an upper infusion tube together by using a connecting piece, so in the process of exhausting the gas, the liquid and the gas volume meeting the requirement can be automatically generated in the dropping pipette. Now, as long as the connecting piece is taken off, the infusion to the patient can be processed untill the needle head comes out the weter, so the utility model not only is time saving and labour saving, but also can avoid the phenomenon of wasting the physic liquor when the exhausting gas is not fluent.

Description

Convenient operation infusion device

This utility model relates to the infusion set of a kind of medical infusion device, particularly a kind of handled easily, is suitable for clinically using when giving patient infusion.

When utilizing transfusion device to give patient infusion, at first to carry out bleeding.This work will be finished minim pipette at short notice and tilts, the syringe needle open and close, and actuator multi-mode operation such as close.When if the air inlet pipe backwater takes place, then also to carry out and to carry on the air inlet pipe, close actuator, push an operation such as minim pipette, therefore, more common nurses carry out deflated phenomenon after having to owing to bleeding is unfavorable a part of medicinal liquid bled off again, like this, not only waste medicinal liquid, and can be difficult to remove with many minute bubbles on the inwall of following tube for transfusion, and then cause a hidden trouble in the air admission patient body.

This utility model is exactly the transfusion device device that a kind of improved, handled easily will be provided, and uses it, not only can reach the once successful purpose of bleeding, nor can adhere to bubble on the inwall of tube for transfusion.

This utility model is achieved in that in the minim pipette water side of transfusion device and is provided with one " gas dome ", to be associated in together with a connecting piece and upper tubing behind the reverse replication of minim pipette, like this, liquid is mobile from lower toward eminence in minim pipette during aerofluxus, when liquid arrives the outlet of tube for transfusion and then flows into tube for transfusion, gas dome is still anhydrous, therefore, can reach the job requirement that aerofluxus finishes to leave in the minim pipette of back an amount of air.

This utility model novel structure, easy to use, safe, can stop the deflated phenomenon of secondary fully and take place, therefore, be particularly suitable for newly appointed nurse and use.Simultaneously,, but determine, therefore, help realizing the standardization issue of this index by the size of gas dome because what of the gas of leaving a blank are not by the nurse in the minim pipette.

Below, will be described in further detail this utility model in conjunction with the accompanying drawings.

Fig. 1 is the sketch map of a kind of concrete structure of this utility model, the situation when representing to carry out aerofluxus after it is installed on the infusion bottle.

Fig. 2 after bleeding finishes, takes down connecting piece, the sketch map when minim pipette enters normal operating conditions.This figure has amplified twice than the minim pipette among Fig. 1.

Fig. 3 is that it is different with the minim pipette structure shown in Fig. 1, Fig. 2 according to the work sketch map of another minim pipette that the utility model proposes, but function is identical.

Fig. 4 is the work sketch map of traditional Mo Feishi minim pipette.

The ratio of Fig. 3, Fig. 4 is identical with Fig. 2.Minim pipette among Fig. 1, Fig. 2, Fig. 3, Fig. 4 is all the A end and is water inlet end, and the B end is the water side.

With reference to Fig. 1, Fig. 2, except that connecting piece ［ 2 ］ and minim pipette ［ 9 ］, the manufacturing and the assembling of all the other air inlet pipe ［ 1 ］, transfusion needle ［ 5 ］, upper tubing ［ 6 ］ and following tube for transfusion ［ 10 ］, adjusting device ［ 4 ］, syringe needle ［ 3 ］ require with traditional mode.

For minim pipette ［ 9 ］, its structure and traditional is it possible that the formula minim pipette is basic identical, difference is that its water side B has and (or self) same structure of water inlet end A is it possible that formula, like this, can be under the UNICOM during tube for transfusion, allow down tube for transfusion ［ 10 ］ stretch into a segment distance h in the minim pipette, thereby form a gas dome ［ 7 ］ in the minim pipette water side.Specification requirement to h is: when minim pipette was similar to cylinder and pipe range and is L, then h must be less than 1/2L.The water inlet end of minim pipette ［ 9 ］ is with the method for communicating of tube for transfusion ［ 6 ］ and is it possible that formula is identical.

Connecting piece ［ 2 ］ is the clip that plastics are cast, and its two ends chuck can block upper and lower tube for transfusion and play the connection fixation, requires during fabrication, can blocking tube for transfusion, is as the criterion but suitably can take off easily again firmly the time.

As shown in Figure 1, together with the reverse replication of the part of upper and lower tube for transfusion, reuse connecting piece ［ 2 ］ is fixed on the upper tubing with minim pipette ［ 9 ］.For the upper tubing that does not make sweep produces gauffer, during manufacturing, can suitably increase the length of connecting piece ［ 2 ］, but this length must tilt to horizontal level and is as the criterion can limit the minim pipette axis.

What deserves to be mentioned is that connecting piece ［ 2 ］ both can be above-mentioned said plastics clip, can be again to resemble papery collar etc. can play the connection effect, again other easy device that can be taken off easily.

The using method of this utility model: with reference to Fig. 1, transfusion needle ［ 5 ］ is thrust in the infusion bottle of hanging, open syringe needle ［ 3 ］ aerofluxus, then liquid enters upper tubing ［ 6 ］, when liquid continues to enter minim pipette ［ 9 ］, because stream from lower toward eminence, so, just in minim pipette, form the gas dome ［ 7 ］ of a sealing under arriving behind the mouth of pipe ［ 8 ］ of tube for transfusion, after tube for transfusion ［ 10 ］ arrives syringe needle ［ 3 ］ under liquid continues to flow through, connecting piece ［ 2 ］ is taken off, then air that gas dome is deposited rises to the water inlet end of minim pipette automatically, minim pipette enters normal operating conditions shown in Figure 2, at this moment, promptly can begin to patient infusion.

Is it possible that the basic structure and function of formula minim pipette, the side lower part in its water side also is provided with a special gas dome ［ 11 ］, when it being pressed the AB direction when replacing minim pipette among Fig. 1, its effect is identical to minim pipette shown in Figure 3 except that possessing.

Need to prove: the structure that only adopts " the minim pipette replication upwards and with a connecting piece is fixed " of the present utility model, and continue to adopt traditional is it possible that the formula minim pipette, though can not in minim pipette, store air automatically, and need the nurse to grasp with eyes control, still, because liquid drives in the wrong direction in minim pipette and moves upward, flow velocity is slower, the nurse can vacate the switching of both hands control syringe needle again, and therefore, this structure also can play good effect to carrying out bleeding easily and accurately.
