Abstract

The utility model discloses a liquid feeding device which comprises a handpiece, a rubber plug and a protective cap, and is characterized in that a plastic part formed by injection molding is used as the handpiece, and the handpiece comprises a handheld handle, a blood passageway I, a blood passageway II, protective wings, a connecting hole and an interlayer groove; the inner part of the handpiece is similar to a T-shaped cavity; the top of the cavity is the blood passageway I, and the blood passageway II are arranged at two ends of the blood passageway I; the protective wings are arranged below the handheld handle and at two sides of the blood passageway; the interlayer groove is arranged at the bottom of the handpiece, and the rubber plug is embedded in the handpiece; the connecting hole is arranged between the interlayer groove and the blood passageway I; an annular boss is arranged on the outer wall; the protective cap is tightly matched with the end part of the interlayer groove; and an annular pin hole is arranged in the center of the protective cap. When the liquid feeding device is operated, medical staff needs to hold the handheld handle of the liquid feeding device with one hand and hold an injector with the other hand, and an injector needle penetrates through the rubber plug and directly reaches the blood passageway through the connecting hole, so that an operator can be prevented from being tainted with blood and medicine which probably leak, and the operator can be protected.

Description

The liquid chemicals dosing plant
Technical field
This utility model relates to a kind of liquid chemicals dosing plant, is adapted at blood of human body and blood component collection or haemodialysis and uses with connecting part on the extracorporeal circulation blood circuit, is used for repeatedly the filling of liquid medicine or the collection of circulation bloody path blood and composition check sample thereof.
Background technology
Now in the clinical treatment; the treatment of blood related fields increases progressively gradually; as infusion of therapeutic, hemodialysis etc. after blood and the blood component collection; these therapeutic processes all can use corresponding in vitro circulation bloody path, in use run into the collection of maybe needing to check the blood sample of usefulness need for blood donor or patient's infusion liquid medicine through regular meeting.Therefore on extracorporeal circulation blood circuit, connect a liquid chemicals dosing plant, can facilitate for clinical position, and increase work efficiency.
Summary of the invention
At above clinical demand situation, it is a kind of easy to use that the purpose of this utility model is to provide, and can protect the liquid chemicals dosing plant of user.
This utility model is realized above-mentioned purpose by the structure of liquid chemicals dosing plant:
This utility model liquid chemicals dosing plant; comprise handpiece, rubber stopper and protective cap; it is characterized in that handpiece is the working of plastics of injection mo(u)lding; it is made of hand holding handle, blood channel I, blood channel II, the protection wing, connecting hole and interlayer groove; the handpiece inner near is like T shape cavity; the cavity top is blood channel I; blood channel II is positioned at the two ends of blood channel I; the protection wing is positioned at hand holding handle below, blood channel both sides; the handpiece bottom is the interlayer groove; embedded rubber stopper has a connecting hole between groove and the blood channel, there is an annular pin hole in protective cap central authorities.
For avoiding the rubber stopper in the interlayer groove to deviate from, this utility model is provided with annular boss at the outer wall of interlayer groove, and the protective cap inwall is provided with and annular boss corresponding annular projection, and assembling back protective cap and interlayer groove end closely cooperate, and can guarantee that rubber stopper does not come off.
Annular boss on the interlayer groove outer wall also deformable is that interlayer groove outer wall end extends internally and forms annular baffle ring, blocks rubber stopper and does not deviate from.
Operation principle of the present utility model is as follows:
This liquid chemicals dosing plant is connected on the extracorporeal circulation blood circuit by flexible pipe or other forms; when needing filling medicine or sampling; hands of medical personnel pinches the hand holding handle of this liquid chemicals dosing plant; the another hands with syringe needle from protective cap top pin hole puncture rubber stopper; injection needle is by the through blood channel I of connecting hole; entry needle contacts with blood in the blood access, and can directly add medicinal liquid or carry out the blood sample collection this moment.Because of the protection wing below hand holding handle, blood sample collection or filling be during liquid medicine, blood and the medicine that can avoid the operator to be infected with may leaking in the operating process play a protective role to the operator.
This utility model has been owing to taked said structure, under the situation that can protect user safety, finishes to the filling of the repeatedly liquid medicine of blood in the extracorporeal circulation blood circuit or the collection of blood sample, for clinical treatment is provided convenience.

The specific embodiment
Embodiment 1
As shown in Figure 1, this liquid chemicals dosing plant comprises handpiece 1, rubber stopper 2 and protective cap 3.As Fig. 2, shown in Figure 4, handpiece 1 is the working of plastics with the injection mo(u)lding of hand holding handle 4, blood channel I 5 and blood channel II 10, the protection wing 6, connecting hole 7, annular boss 8 and interlayer groove 9 formations.
The handpiece inner near is like T shape cavity; the cavity top is blood channel I 5; blood channel II 10 is positioned at the two ends of blood channel I 5; the protection wing 6 is positioned at the hand holding handle below; the blood channel both sides; the handpiece bottom is an interlayer groove 9; embedded rubber stopper 2; one connecting hole 7 is arranged between interlayer groove 9 and the blood channel I 5; annular boss 8 is arranged on its outer wall, on protective cap 3 inwalls annular protrusion 13 is arranged, during assembling; protective cap 3 was pushed away annular boss 8 on interlayer groove 9 outer walls; annular protrusion 13 in it is spacing by the annular boss 8 on interlayer groove 9 outer walls, can not after move, shown in Fig. 5 partial enlarged drawing.Protective cap and interlayer groove closely cooperate, and guarantee that the rubber stopper in the interlayer groove is not deviate from.There is an annular pin hole 11 in the central authorities of protective cap 3, and when medical worker's liquid feeding or blood sample collection, syringe needle just is punctured in the blood channel from this hole.
Shown in Figure 6 is the another kind of form of the annular boss on interlayer groove 9 outer walls, is the annular baffle ring 12 that extends internally in the cell wall lower end and form, and can prevent effectively that rubber stopper 2 is deviate from the groove.
The above description of being done in conjunction with this utility model embodiment does not constitute any qualification to protection domain of the present utility model.Those skilled in the art can make various changes on basis of the present utility model, these change all should think and fall within the protection domain that this utility model claim limited.
