Abstract
The utility model discloses a screw propulsion type double-tip needle medicine mixing nozzle. A double-tip needle consists of a needle seat, an upper needle and a lower needle, wherein the edge of the needle seat extends along a direction of the upper needle to form a medicine mixing body which has a cup body structure; an inner sleeve and an outer sleeve are sleeved outside the lower needle; an outer thread is formed on the outer wall of the inner sleeve; a membrane is arranged at the bottom of the inner sleeve; an inner thread is formed on the inner wall of the outer sleeve; one end of the outer sleeve is fixed on the needle seat; and the other end of the outer sleeve is screwed with the inner sleeve. Before medicine mixing, the inner sleeve is screwed with the bottom of the outer sleeve, and the inner sleeve and the outer sleeve form a lower needle protecting sleeve, so that the lower needle is effectively protected; during medicine mixing, a sealing film at the upper port of the medicine mixing body is torn down, the upper needle pierces a sealing plug of a penicillin bottle, the bottom of the inner sleeve is pressed against a sealing cover on a transfusion soft bottle or transfusion soft bag, and the inner sleeve is screwed into the outer sleeve, so that medicines and a solution can be mixed by extruding the transfusion soft bottle or transfusion soft bag when the lower needle pierces the membrane below the lower needle and the sealing plug on the transfusion soft bottle or transfusion soft bag; and therefore, the medicines can be simply mixed in a time-saving mode.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of crosspointer medicine mixing mouth.
Background technology
For the medicine in the cillin bottle is added in the solution in transfusion flexible bag or the soft transfusion bottle, then mixed solution is imported such as the patient in the clinical mechanism of hospital.
In the prior art, often adopt syringe that the solution in the medicine in the cillin bottle and transfusion flexible bag or the soft transfusion bottle is mixed.At first, use syringe, then, also use this syringe that mixed solution is moved in transfusion flexible bag or the soft transfusion bottle in the input of the solution in transfusion flexible bag or the soft transfusion bottle cillin bottle.At present, in the clinical mechanism of hospital, also use this kind mode usually, but the error of making up a prescription not only appears in this mixed prescription formula complicated operation, time-consuming easily, also very likely in mixed medicine process, introduce and pollute, influence drug safety, cause serious malpractice.So improving and mixing the prescription formula is a necessary task of preparing before the transfusion.
The utility model content
To the above-mentioned deficiency that exists in the prior art, this utility model provides a kind of to need puncture once just can realize mixing medicine, and the operation of mixed medicine is simpler, more timesaving screw-pushing type crosspointer medicine mixing mouth.
In order to solve the problems of the technologies described above, this utility model has adopted following technical scheme: screw-pushing type crosspointer medicine mixing mouth, and crosspointer is made up of needle stand, last pin and following pin; Last pin and following pin are arranged on the both sides of needle stand; Last pin and play pin are hollow structure and are interconnected, and the mixed medicine body that the pin direction that makes progress along the edge of needle stand extends to form a cup body structure overlaps and overcoat in the infra pin is with outward; The outer wall of cover is provided with external screw thread in said, and the inwall of said overcoat is provided with female thread; One end of overcoat is fixed on the needle stand, and the other end screws interior through threaded engagement and puts.
As a kind of preferred version of this utility model, the cross section of said interior cover is provided with barrier film, and barrier film is positioned at the below of pin down.
As the another kind of preferred version of this utility model, said pin and the following pin gone up is all along the axis setting of the mixed medicine body of cup body structure.
As a kind of improvement project of this utility model, the port of said mixed medicine body is provided with diaphragm seal.
As the another kind of improvement project of this utility model, on the inwall that mixes the medicine body, be symmetrically arranged with at least two and be barb-like and be used to prevent the anti-slide fastener that cillin bottle is loosening.
As another improvement project of this utility model, said crosspointer, mixed medicine body, interior cover and overcoat are encapsulated in the outer package.
The beneficial effect of this utility model is: this screw-pushing type crosspointer medicine mixing mouth is before mixing medicine; Interior cover screws the bottom of its external sleeve, and interior cover and overcoat are formed pin protective sleeve down, and following pin is positioned at protective sleeve; The sharp degree of pin needle point is protected effectively, and guaranteed the cleaning of time pin; When mixing medicine; Only need tear and mix the diaphragm seal that medicine body port is provided with; With the sealing-plug of last needle-penetration cillin bottle, interior cover bottom is propped up the seal cover on soft transfusion bottle or the transfusion flexible bag and interior cover is advanced to the overcoat inward turning, make down the broken membranous while of below of acupuncture; And piercing through the sealing-plug in the seal cover on soft transfusion bottle or the transfusion flexible bag, extruding transfusion flexible bag or soft transfusion bottle just can make the medicine in the cillin bottle mix with transfusion flexible bag or the interior solution of soft transfusion bottle.It is simpler to mix the medicine operation, more saves time; Moreover also successfully realized making up a prescription and two stages of mixed medicine independent sealed, reduced mix the time restriction of medicine in the infusion process from making up a prescription to, strengthened the safety of mixed reagent.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done to describe in further detail.
As shown in Figure 1, screw-pushing type crosspointer medicine mixing mouth, this crosspointer is made up of needle stand 1, last pin 2 and following pin 3.Last pin 2 and play pin 3 are arranged on the both sides of needle stand 1, and last pin 2 and following pin 3 are hollow structure and are interconnected, and pin 2 directions that make progress along the edge of needle stand 1 extend to form the mixed medicine body 4 of a cup body structure.Cover 11 and overcoat 12 in infra pin 3 outer being with, the outer wall of interior cover 11 is provided with external screw thread, and the inwall of overcoat 12 is provided with female thread, and an end of overcoat 12 is fixed on the needle stand 1, and the other end screws on interior cover 11 through threaded engagement.
In cover 11 cross section be provided with barrier film 13, and barrier film 13 is positioned at the below of pin 3 down, the port of mixing medicine body 4 is provided with diaphragm seal 5, crosspointer, mixes medicine body 4, interior cover 11 and overcoat 12 and is encapsulated in the outer package.Before mixing medicine; Diaphragm seal 5 and interior cover 11 cooperate outer package (like sealing bag) to use with the following pin protective sleeve that overcoat 12 is formed; Can make mixed medicine body 4 be in sealing state with crosspointer; Not only keep mixed medicine body 4, gone up pin 2 and play pin 3 has good cleannes before use, also effectively protected the sharp degree of last pin 2 and following pin 3 and the internal structure of mixed medicine body 4, avoided the damage in the transportation; During use, take outer package apart, tear diaphragm seal 5 and get final product.
