Abstract
The utility model discloses a disposable infusion pump flow speed switch which comprises an infusion pipe. More than one infusion pipe branch is connected to a front infusion pipe via a front connection head, and the infusion pipe branch is connected to a bottom seat of the switch. The openings of the pipe branches are arranged on the bottom seat of the switch, flow limiting pipes with unequal length are connected to the bottom seat of the switch and the openings of the flow limiting pipes are arranged on the bottom seat of the switch. Each flow limiting pipe is connected to a back infusion pipe via a back connection head. A knob is arranged on the bottom seat of the switch, and the back of the knob is provided with a medicine guiding slot. The utility model can also adopt the technical scheme that two rubber pipes are connected to the front connection in parallel via the infusion pipe branch, after passing through the bottom seat of the switch, the rubber pipes are respectively connected to the flow limiting pipes with unequal length and the back of the bottom seat of the switch is provided with a switch knob of a flow cutting bulgy block. The utility model can make the disposable infusion pump autonomously adjust the flow rate of medicine liquor when medicine for relieving pain is automatically added to a patient who is operated.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, is the flow rate switch of using on the disposable use infusion pump specifically.
Background technology
The main clinical practice of disposable use infusion pump is injected analgesic in postoperative.A kind of disposable use infusion pump was arranged in the past, its administering mode is to continue feeding to add the automatic control feeding, lasting feeding is that flow reaches pain relieving as required by micro-flow control tube control medicinal liquid, the automatic control feeding is when lasting feeding dose is not enough, patient is according to the autonomous dosing of pain situation, it is finished by a pain relieving switch, this pain relieving switch be by spring and on briquetting compress or unclamp tube for transfusion, whether the decision dosing, though it has the function of autonomous dosing, but its shortcoming is its dosage is constant, i.e. automatic control adds dose and can not add and subtract according to the state of an illness.
Summary of the invention
This utility model is intended to provide the flow rate switch that a kind of disposable use infusion pump is used, and when it injects analgesic automatic control feeding at patient's postoperative, can regulate the flow velocity of medicine easily.
Task of the present utility model is done in such a way that disposable use infusion pump flow rate switch, and it includes tube for transfusion; Connecting transfusion arm more than one by front connector on the pro-tube for transfusion, this transfusion arm is connected on the switch pedestal, and on switch pedestal, be provided with tube opening, the current limiting tube that corresponding connection is uneven in length on each tube opening opposite switch pedestal, each current limiting tube has the current limliting tube opening on switch pedestal, each current limiting tube is connected on the tube for transfusion of back by the back joint, the turn-knob that diameter is complementary with it is installed on switch pedestal, and the back side of turn-knob has and can lead the medicine groove with what prop up that tube opening and current limiting tube opening be connected.
Finish task of the present utility model, can also be by the following technical solutions, disposable use infusion pump flow rate switch, it includes tube for transfusion, connect front connector on tube for transfusion, by the parallel connection two root rubber pipes of transfusion arm, this two root rubber pipe is connected on the current limiting tube that is uneven in length after switch pedestal is passed in the front connector, the switch turn-knob that is complementary with it is installed on switch pedestal, and the back side of this switch turn-knob is equipped with the projection that dams.This utility model can make the disposable infusion pump when injecting analgesic automatic control dosing to postoperative patient, independently regulates the flow velocity of medicinal liquid.
Description of drawings
Fig. 1 is this utility model groove conduction type structural representation; Fig. 2 is this utility model projection shutoff type structural representation.
Among the figure: 1, preceding tube for transfusion; 2, front connector; 3, transfusion arm; 4, switch pedestal; 5, a transfusion tube opening; 6, current limiting tube; 7, current limiting tube opening; 8, back joint; 9, back tube for transfusion; 10, twisted; 11, lead the medicine groove; 12, rubber tube; 13, the projection that dams.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.This flow rate switch is arranged on the middle part of once using infusion pump, and promptly its front-end and back-end all are connected on the tube for transfusion.Fig. 1 is this utility model groove conduction type structure, it is to connect front connector 2 on the pro-tube for transfusion 1, at the transfusion arm 3 that connects in the front connector 2 more than two, transfusion arm 3 is connected on the switch pedestal 4, and on switch pedestal 4, having a transfusion tube opening 5, the side relative with transfusion arm 5 on switch pedestal 4 connects current limiting tube 6, being uneven in length of every current limiting tube 6, thereby it is different to cause the medicinal liquid flow velocity to have.During concrete the application, then be to determine medicinal liquid flow with little throughput tachymeter finding speed, current limiting tube 6 is provided with current limiting tube opening 7 on switch pedestal 4, every current limiting tube 6 all is connected on the joint 8 of back, tube for transfusion 9 after back joint 8 is ined succession, turn-knob 10 and switch pedestal 4 are complementary, and are provided with at its back side and lead medicine groove 11, and the rotation by turn-knob can make transfusion arm 3 and each current limiting tube 6 conducting or close.
When this utility model design has two medicinal liquid flows, can also adopt the following specific embodiment.Preceding tube for transfusion 1 connects two transfusion arms 3 by front connector 2, on two transfusion arms 3, connect two root rubber pipes 12 respectively, and two root rubber pipes 12 pass from switch pedestal 4, then parallel being connected on two current limiting tubes that are uneven in length 6, current limiting tube 6 is connected on the tube for transfusion 9 of back by back joint 8, turn-knob 10 and switch pedestal 4 are complementary, be fixed with the projection 13 that dams in its back, this projection 13 that dams can rotate to and compress rubber tube 12, medicine in the rubber tube of being pressed is dammed, and the medicine in another root rubber pipe is unimpeded.The length of current limiting tube 6 is determined speed and medicinal liquid flow as required with little throughput tachymeter equally.
Claims (1)
