Abstract
The utility model relates to a discolor film for an injector used in clinical anesthesia, including an injector, a lumbar anesthesia needle; wherein, a transparent discolor film interface is arranged between the injector and the lumbar anesthesia needle; the middle part of the discolor film is provided with a transparent hollow element whose empty chamber is provided with a white or light discolor film; the both sides of the empty element are provided with a tube interface whose one end connects to the tube interface of the lumbar anesthesia needle and the other end connects to the tube interface of the injector. The discolor film will not change when pH<7 and will change color when pH>7. The hollow element can be a cylinder, rhombus and a rectangular. The utility model is simple and reasonable in structure, convenient for observing the test results, which also has the advantages of direct viewing, safe and reliable results.
Description
Technical field
This utility model relates to a kind of syringe variable color film device, syringe variable color film joint in the clinical anesthesia of medical domain.
Background technology
In the clinical anesthesia of medical science, when doing lumbar puncture, often to differentiate at present cerebrospinal fluid and other liquid.In the lumbar puncture process, surgical doctor in the past mainly is to judge the degree of depth and the position that puncture is carried out according to clinical experience, then, do not have objective index, very easily cause the error in the judgement according to the temperature of liquid that obtains, the character that viscosity is distinguished liquid.And the success or not of puncture directly has influence on the effect of lumbar anesthesia and the complication of patient's postoperative etc., and cerebrospinal fluid can be judged the degree of depth and the position of puncture, so the qualitative judgement of cerebrospinal fluid just seems very important.Normally used local anesthetic is as the normal saline of 1～2% lidocaine hydrochloride and 0.5～0.75% hydrochloric acid cloth caine and 0.9% on clinical medicine, they are the same with cerebrospinal fluid all to be colourless transparent liquid, 1～2% lidocaine hydrochloride and 0.5～0.75% hydrochloric acid cloth caine are acid (PH＜7), 0.9% normal saline is neutral (PH ≈ 7), and cerebrospinal fluid is an alkalescence (PH＞7), so can produce different color change to reagent paper according to the liquid different pH values, judge the character of liquid.Present discrimination method mainly is to use reagent paper, with the fluid drips of releasing or flow out on reagent paper, judge according to the color of reagent paper then, whether detected cerebrospinal fluid, this mode is cumbersome, and along with the extraction of syringe, cerebrospinal fluid runs off more, badly influence patient's intracranial pressure, make patient's post-operative complication probability increase greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and reasonable, convenient and practical syringe variable color film device, to overcome weak point of the prior art.
Variable color film device by this purpose design comprises syringe, and the lumbar anesthesia puncture needle is provided with water white variable color film joint between syringe and the lumbar anesthesia puncture needle.
Variable color film joint middle part is water white hollow body, is provided with the variable color film of white or light color in the middle of the cavity of hollow body, and the both sides of hollow body are respectively arranged with pipe joint, and one terminates to the pipe joint of lumbar anesthesia puncture needle, and the other end is received the pipe joint of syringe.The variable color film does not change when running into PH＜7, when running into PH＞7, changes color.Hollow body can be cylinder, rhombogen, cuboid.
This utility model is simple and reasonable, for testing result can observe immediately, directly perceived and safe and reliable.
Description of drawings
Fig. 1 is this utility model one example structure sketch map.
Fig. 2 is the plan structure sketch map of Fig. 1
Fig. 3 is a lumbar anesthesia puncture needle structural representation.
Fig. 4 is the syringe construction sketch map.
Fig. 5 uses the reference configuration sketch map for this utility model.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described.
Referring to Fig. 1-Fig. 2, this water white variable color film joint 1, the middle part is water white hollow body, this hollow body is a cylinder, is provided with the variable color film 8 of white or light color in the middle of the cylindrical cavity.Cylindrical both sides are respectively arranged with joint 2 and 3.
Referring to Fig. 3, lumbar anesthesia puncture needle 5 is provided with pipe joint 4.
Referring to Fig. 4, syringe 7 is provided with pipe joint 6.
Referring to Fig. 1 and Fig. 5, during clinical use, lumbar anesthesia puncture needle 5, variable color film joint 1 and syringe 7 are connected together, and the pipe joint 2 and 3 that water white variable color film joint 1 both sides are provided with joins with the pipe joint 4 of lumbar anesthesia puncture needle 5 and the pipe joint 6 of syringe 7 respectively successively.The liquid that extracts enters lumbar anesthesia puncture needle 5, variable color film joint 1 and syringe 7 successively.Variable color film 8 does not have change in color when running into the liquid of PH＜7; When running into cerebrospinal fluid, cerebrospinal fluid is alkalescence (PH＞7), and variable color film 8 is become coloured by original white or light color, perhaps redness or purple.Because hollow cylinder is water white, when color, can observe at once, at this moment, patient or anaesthetist perception at once, the carrying out of decision further work.
Hollow body of the present utility model also can be bullet, rhombogen or cuboid.
Claims (4)
1. a syringe variable color film device comprises syringe (7), and lumbar anesthesia puncture needle (5) is characterized in that being provided with water white variable color film joint (1) between described syringe (7) and the lumbar anesthesia puncture needle (5).
