Abstract

The utility model discloses a multi-channel medicating instrument with a rotary switch. The multi-channel medicating instrument with the rotary switch comprises a medicine-mixing connector, medicine-mixing mouths and a valve core. Each medicine-mixing mouth comprises a medicine-mixing clamp body and a medicating needle fixed on the bottom inside the medicine-mixing clamp body. The valve core is rotatably installed in the medicine-mixing connector and matched with the medicine-mixing connector in sealed mode. A through hole is disposed in the sidewall of the valve core. At least two branch connectors are disposed on the outer circumference of the medicine-mixing connector. Each branch connector is connected with one medicine-mixing clamp body and communicated with an inner channel of one medicating needle. When the valve core rotates in the medicine-mixing connector, the through hole can be alternately communicated with the branch connectors on the medicine-mixing connector. The multi-channel medicating instrument with the rotary switch adopts the medicine-mixing connector provided with at least two branch connectors and the valve core provided with the through hole in the sidewall to form the rotary switch. When the valve core rotates in the medicine-mixing connector, the through hole in the valve core can be alternately communicated with the branch connectors on the medicine-mixing connector. Each branch connector is connected with one medicine-mixing mouth. In the process of mixing medicine, the multi-channel medicating instrument not only can achieve selective medicine-mixing through the rotary switch but also can achieve mixing of two or more bottles of medicine.

Fig. 1 is the structural representation of the multichannel dosing appearance of band rotating switch.
In the accompanying drawing: 1-mixed medicine interface; 2-medicine mixing mouth; 3-spool; 4-through hole; 5-support interface; 6-pedestal; 7-mixed medicine card body; 8-dosing pin; 9-hands handle; 10-type self-destroyed sealing shroud.
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, the multichannel dosing appearance of band rotating switch comprises and mixes medicine interface 1, medicine mixing mouth 2, spool 3 and pedestal 6.Medicine mixing mouth 2 comprises mixed medicine card body 7 and dosing pin 8, and dosing pin 8 fixedly is located at the bottom of mixing in the medicine card body 7.Mix medicine interface 1 and be located on the pedestal 6, mixed medicine interface 1 extends outward pedestal 6 by the mixed medicine passages in the pedestal 6 and forms, and mixing medicine interface 1 is the cylindrical hollow structure.Spool 3 mixes in the medicine interface 1 through rotating being installed in of the mode of clamping, and the outer wall of spool 3 also cooperates with the inner wall sealing of mixed medicine interface 1.On the sidewall of spool 3, has a through hole 4; At least be provided with two support interfaces 5 (in the present embodiment on the excircle of mixed medicine interface 1; On the excircle of this mixed medicine interface 1, be symmetrically distributed with four support interfaces 5; All support interface 5 relative spools 3 also are symmetrically distributed), each support interface 5 is connected with the mixed medicine card body 7 of a medicine mixing mouth 2, support interface 5 and with the medicine mixing mouth that is connected 2 on dosing pin 8 in passages communicate.When spool 3 rotated in mixed medicine interface 1, through hole 4 can be communicated with the support interface 5 on the mixed medicine interface 1 by turns.
In the present embodiment, spool 3 is provided with to stretch out and mixes medicine interface 1 and be used to drive the handle 9 that spool 3 rotates, and just can drive spool 3 easily through this handle 9 and in mixed medicine interface 1, rotate.If the installation site of handle 9 is corresponding with the position of through hole 4, handle 9 turns to when aiming at support interface 5 that mixes on the medicine interface 1, and the through hole 4 on this spool 3 just is communicated with this support interface 5.It is one-body molded to mix medicine card body 7, support interface 5 and mixed medicine interface 1, and technology is simple, be prone to realize, and cost is low.
Dosing pin 8 is positioned on the needle point that mixes medicine card body 7 and is with type self-destroyed sealing shroud 10; Type self-destroyed sealing shroud 10 adopts elasticity, toughness or soft material to process; Type self-destroyed sealing shroud 10 has elasticity or toughness; Can be unlikely to get loose using overall process all closely to contact with dosing pin 8 outer walls from line slip.This type self-destroyed sealing shroud 10 makes passage and the support interface 5 interior passages in the dosing pin 8 be in sealing state, effectively avoids passage and support interface 5 interior passages in the dosing pin 8 to be polluted.When mixing medicine; The sealing-plug of medicament reservoir is aimed at the needle point of dosing pin 8; Exert pressure downwards, along with upwards the puncture sealing-plug of medicament reservoir of needle point, type self-destroyed sealing shroud 10 is punctured and is moved down along dosing pin 8; This type self-destroyed sealing shroud 10 does not influence the sealing-plug of dosing pin 8 puncture medicament reservoirs, helps medicament reservoir on the contrary and is connected with infusion vessel is aseptic.Because of this type self-destroyed sealing shroud 10 has better elastic; In the time of in medicament reservoir snaps in mixed medicine card body 7; Type self-destroyed sealing shroud 10 is compressed on dosing pin 8; Type self-destroyed sealing shroud 10 after this compression can prevent effectively that with the anti-slide fastener on the mixed medicine card body 7 medicament reservoir is loosening, and the type self-destroyed sealing shroud 10 after the compression seals the grafting site between medicament reservoir and the mixed medicine card body 7 fully, and the medicinal liquid seepage takes place when avoiding mixing medicine; Also but the absolutely gas-tight property in the medicament reservoir behind the mixed medicine of strict guarantee is stopped microbiological contamination danger.
Implement to mix before the medicine; Spool 3 is in closed condition with the rotating switch that mixed medicine interface 1 is formed; Make the transfusion solvent in the infusion vessel keep sealing and not contacting with dosing pin 8; The solvent of avoiding infusing pours into and mixes in the medicine card body 7 through mixing medicine interface 1, support interface 5 and dosing pin 8, thereby produces leakage, not only strict assurance in the infusion vessel transfusion solvent volume but also avoided using before pollution; After support interface on the through hole on the spool 34 and the mixed medicine interface 15 is corresponding (be spool 3 form with mixed medicine interface 1 rotating switch be in opening); Mix medicine interface 1 and be communicated with, realize mixing medicine thereby make the transfusion solvent can flow into medicament reservoir with dosing pin 8.
When using the multichannel dosing appearance of this band rotating switch; Has the rotating switch that the spool 3 of through hole 4 is formed through control by mixed medicine interface that is provided with at least two support interfaces 1 and sidewall; Through hole 4 when spool 3 rotates in mixing medicine interface 1 on the spool 3 can be communicated with the support interface 5 on the mixed medicine interface 1 by turns, when mixing medicine, both can realize selectively mixing medicine through this rotating switch; The medicament mixed more than two bottles or two bottles can be realized again, thereby dosage can be effectively arranged in pairs or groups.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation this utility model; Although with reference to preferred embodiment this utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of this utility model; And not breaking away from the aim and the scope of this utility model technical scheme, it all should be encompassed in the middle of the claim scope of this utility model.
