Abstract
The utility model discloses an automatic control analgesic device for patients after operations, which mainly comprises a syringe, a one-way valve and a medicine storage can, wherein, the medicine storage can is installed at the left side of the utility model of which the right side is provided with the syringe; the liquid outlet of the syringe is arranged below the analgesic device and is connected with a three-way joint, and the other two ends of the three-way joint are respectively connected with one one-way valve; one end of the three-way joint is connected with the liquid outlet, and the other end of the three-way joint is connected with the epidural catheter of the hard mask of one patient; the tail part of a needle bolt is connected with the upper wall of the analgesic device through an extension spring; a vernier is installed in a rectangle toothed hole on a cover casing. The utility model has the advantages of small volume, low material consumption, low cost and convenient use.
Description
This utility model relates to a kind of nonrecoverable clinical treatment utensil, a kind of specifically syringe.
Pain relieving is to adopt intravenous administration or through epidural catheter injection analgesic postoperative patient is carried out pain relieving with syringe after traditional operation.The pain relieving method that this is traditional, otherwise the inaccurate pain relieving of dosage is unreliable; Very big gap is arranged between medication and patient's the actual demand, can not control voluntarily according to patient's needs, and syringe easily pollutes.
The purpose of this utility model is to provide a kind of dosage accurate, and patient can oneself control and postoperative patient automatic control pain relieving device that be difficult for pollution.
The purpose of this utility model is achieved in that in the left side of pain relieving device medicine tin is installed, the right side is equipped with syringe, the liquid outlet of syringe is positioned at the below of pain relieving device, the liquid outlet of syringe is connected with three way cock's a end, three way cock's two ends in addition respectively connect an end of a unidirectional flap valve, and the other end of the unidirectional flap valve of left end is connected with the liquid outlet of medicine tin; The other end of the unidirectional flap valve of right-hand member is connected with patient's epidural catheter, on the afterbody sidewall of the pintle of syringe push button is installed, and is connected with extension spring between afterbody and pain relieving device upper wall, and the rectangle perforation is arranged on the case of pain relieving device, and vernier is installed in the rectangle perforation.
Owing to adopted such scheme, make by vernier location that to set dosage more accurate, as long as just can finish the injection process owing to push away push button, so patient oneself can control administration according to actual needs voluntarily, because the pain relieving device is closed syringe, is not subjected to the pollution of air so guaranteed medicinal liquid.This pain relieving body long-pending little, materials are few, cost is low, easy to use.

Fig. 2 postoperative patient automatic control pain relieving device casing structure figure.
(1) syringe, (2) push button, (3) vernier, (4) extension spring, (5) three way cock, (6) unidirectional flap valve, (7) medicine tin, (8) dosing hole, (9) air filter, (10) sealing shroud among the figure.
Medicine tin (7) lower end that is installed in pain relieving device left side is a liquid outlet, the upper end is provided with dosing hole (8) and air filter (9), the lower end that is installed in the syringe (1) on pain relieving device right side is a liquid outlet, liquid outlet is connected with three way cock's (5) a end, three way cock's (5) two ends in addition respectively connect an end of a unidirectional flap valve (6), and the other end of the unidirectional flap valve of left end (6) is connected with the liquid outlet of medicine tin (7); The other end of the unidirectional flap valve of right-hand member (6) is connected with patient's epidural catheter.On the afterbody sidewall of syringe (1) pintle push button (2) is installed; Be connected extension spring (4) between pintle afterbody and the pain relieving device inwall; Be connected with sealing shroud (10) between syringe (1) sleeve pipe rear portion and the pintle.Vernier (3) is installed in the rectangle perforation on the pain relieving device case, and the rectangle perforation is arranged on the movement locus of push button on the pintle (2).
During use, in medicine tin (7), fill it up with medicinal liquid from the dosing hole (8) of medicine tin (7), according to patient's needs vernier (3) is set on certain rectangle perforation, at this moment because the effect of syringe (1) pintle afterbody extension spring (4) upwards is pulled to vernier (3) with the syringe pintle and locates, the push button on the pintle (2) is limited by vernier (3).During the pintle pulling, the sleeve pipe of syringe (1) is air-breathing because the opening of the effect left end of unidirectional flap valve (6), the obturation of right-hand member, medicinal liquid is inhaled in the sleeve pipe, when injection, promote the obturation of push button (2), the opening of right-hand member owing to the effect left end of unidirectional flap valve (6), medicinal liquid is injected in the human body, so constantly circulation.
Claims (2)
1, a kind of postoperative patient automatic control pain relieving device, comprise, syringe, unidirectional flap valve and medicine tin, it is characterized in that: medicine tin is installed in the left side at the pain relieving device, the right side mounting of syringe, the liquid outlet of syringe is positioned at the below of pain relieving device and connects with the three way cock, three way cock's two ends in addition respectively connect an end of a unidirectional flap valve, and the other end of the unidirectional flap valve of left end is connected with the liquid outlet of medicine tin; The other end of the unidirectional flap valve of right-hand member is connected with patient's epidural catheter, on the afterbody sidewall of the pintle of syringe push button is installed, and is connected with extension spring between pintle afterbody and the pain relieving device upper wall, in the rectangle perforation on the case of pain relieving device vernier is installed.
2, postoperative patient automatic control pain relieving device according to claim 1, it is characterized in that: the upper end of medicine tin is provided with dosing hole and air filter; Be connected with sealing shroud between injection cannula rear portion and the pintle; Rectangle perforation on the case is arranged on the movement locus of push button on the pintle.
