Description
Technical field
The utility model relates to a kind of single use cavum epidural puncture indicator, be applicable to cavum epidural puncture instruction.
Background technology
During current dura mater chamber puncture, determine what tissue depth had been come with feel by rule of thumb by medical worker.Whether arrive epidural space position cannot determine, repeated localised puncture pin repeatedly, therefore the puncture needle operating time is long, brings misery to patient.
Although have a kind of epidural space indicator with membrane filtration at present, due to elastomer film and joint suitable for reading, lack compression and hermetically-sealed construction, easily gas leakage, leakage in piercing process, impact normally uses, and does not have indicative function.
Summary of the invention
This utility model object provides a kind of single use cavum epidural puncture indicator for above-mentioned weak point, during easy to operate, cavum epidural puncture, instruction accurately, safe and effective, the time that anaesthetist finds epidural space position can be shortened, alleviate patient's misery.
Single use cavum epidural puncture indicator takes following technical scheme to realize:
Single use cavum epidural puncture indicator comprises cavity, one-way seal valve, clamp ring, upper cover, indicating film and O-ring seals.Cavity side is provided with Luer inner conical connector, and cavity opposite side is provided with Rule outer cone joint, is provided with one-way sealing valve housing and clamp ring mounting groove bottom Luer inner conical connector.Cavity upper end is provided with buckle, is convenient to indicating film and upper cover are installed, be convenient to sealing and install.Cavity bottom is hermetically-sealed construction, is arranged to one with cavity.
Upper cover upper end is provided with O-ring seals mounting groove, and upper tops is provided with through hole.One-way seal valve adopts silica gel to make.One-way seal valve is arranged on the one-way sealing valve housing bottom Luer inner conical connector, and clamp ring is arranged in clamp ring mounting groove, and locking one-way seal valve plays sealed non-backing and uses.
Indicating film is arranged on cavity upper end, O-ring seals is arranged in O-ring seals mounting groove, and upper cover is arranged on cavity upper end, fixed by snap, O-ring seals is fixed sealing indicating film, indicating film in use can not be leaked gas, leak and play sealing and indicative function.
Anti-skidding striped is set in cavity both sides, good hand touch, convenient operation.
Described cavity and upper cover adopt polyethylene transparent material to make.
Described Rule inside and outside circle taper joint is by national standard design.
Described one-way seal valve adopts silica gel to make.Described O-ring seals adopts silica gel to make.
Described clamp ring adopts polythene material to make.
Described indicating film adopts Polyurethane Thermoplastic Elastomer rubber.
When single use cavum epidural puncture indicator uses, by syringe and Luer inner conical connector connecting puncture needle, puncture needle is connected with Rule outer cone joint and puncture needle is inserted subcutis utilizes syringe to saline injection in cavity or air 1mL, indicating film is made to be hemispherical, both hands hold the both wings of puncture needle, slow propelling puncture needle, find hemispherical in progradation, both hands hold puncture needle both wings, slow propelling puncture needle, in progradation, find that hemispherical indicating film has obviously reduce, or normal saline subcutaneously organizes flowing, show that puncture needle arrives epidural space, arrive the correct position of injecting narcotic, stagnate propelling immediately, can injecting narcotic.
Single use cavum epidural puncture indicator feature:
1, the anti-skidding design in cavity both sides, convenient operation in use;
Bring signal designation 2, to anesthesia art, reduce operation risk;
3, anesthesia amount can be controlled better, more accurately, reduce anesthesia art difficulty;
4, single use, avoids cross infection;
5, easy to use, directly perceived, safe, effective;
6, reduce preoperative workload, shorten the time, improve the success rate of operation;
7, the drawback of tradition anesthesia can be avoided;
8, special indicating film design, signal designation is more accurate;
9, this product teaching process person can accurately arrive the tissue location of anesthesia.
10, the inside and outside Rule on cavity is designed according to national standard.
Single use cavum epidural puncture indicator is reasonable in design, compact conformation, and during easy to operate, cavum epidural puncture, instruction is accurately, safe and effective, can shorten the time that anaesthetist finds epidural space position, alleviate patient's misery.Single use cavum epidural puncture indicator is applicable to epidural anesthesia art, in puncture process, provide signal designation for puncture needle needle point arrives at epidural space.
