Description

Nerve block anesthesia device under single-person operation supersound guide

Technical Field

The invention relates to the technical field of medical treatment, in particular to a nerve block anesthesia device under ultrasonic guidance by a single person.

Background

The operation anesthesia can effectively solve the pain problem of a patient in the operation, the postoperative pain problem of the patient can be effectively solved by using the nerve block, the postoperative pain is nociceptive pain, the postoperative pain is effectively relieved, the pain of the patient is relieved, the disease rehabilitation is facilitated, the social and economic benefits are also great, in the clinical work, a doctor always realizes complete postoperative pain relief on the compound nerve block anesthesia of the patient, the peripheral nerve block under the ultrasonic guidance is one of the main methods for postoperative pain relief of four limbs and a body part, and the important clinical application value of the peripheral nerve block under the ultrasonic guidance is fully embodied.

The principle of nerve block anesthesia is to inject local anesthetic near the nerve root that needs anesthesia, blocks the nerve root and innervates the region, at whole in-process, need to be interrupted and withdraw the liquid medicine to keep the angle of pjncture needle and the fixed of position, can not miss the blood vessel with the local anesthetic, carry out nerve block under the supersound guide and can pinpoint the nerve root, improve success rate and anesthesia quality, reduced the relevant complication of nerve block.

Before the nerve block anesthesia operation is completed, usually, a doctor with rich experience punctures through ultrasonic positioning, another doctor needs to push local anesthetic liquid medicine, intermittent back suction is carried out in the injection process to avoid the local anesthetic from entering blood vessels by mistake, meanwhile, the medicine pushing resistance is felt, the puncture needle is prevented from entering a nerve bundle membrane, in a near stage, the nerve block operation idea is large-capacity medicine feeding, higher and more accurate pursuing is carried out on the medicine feeding pressure of the part injected with the local anesthetic, therefore, the nerve block anesthesia operation can be completed only by mature matching of at least two doctors with rich experience, if no person is matched, an operator needs to hold an ultrasonic probe, and holds an injector filled with the local anesthetic liquid medicine by one hand, the injector is directly connected with a block needle, but when the injector filled with the liquid medicine is held by one hand, the length is too long to control the needle feeding direction of the block needle, the holding of the medicine is inconvenient, and the operation effect is influenced. When large-capacity administration is needed for nerve block at certain parts, the drug pushing resistance of a 50ml syringe is large, the single-person operation is extremely inconvenient, the drug pushing resistance is not easy to perceive, and the peripheral structure is possibly damaged.

Meanwhile, the change of the injection needle around the blood vessel and the nerve is observed at any moment in the puncture process, but the nerve is often positioned at the inner side of the blood vessel and cannot be directly injected into the nerve by using the direct puncture needle, so that the medicine injection cannot be accurately controlled, and the anesthesia effect is often poor.

The traditional injection pump comprises a stepping motor and a driver thereof, a screw rod, a bracket and the like, wherein the stepping motor rotates to drive the screw rod to change the rotary motion into linear motion when the traditional injection pump works, the injection pump obtains a set rotating speed through the rotation of the motor, pushes a piston of an injector to inject and infuse, and inputs liquid medicine in the injector into a human body. Generally speaking, the injection action of the injection pump is completed by a direct current motor, the rotation of the direct current motor is converted into linear motion through a driving wheel and a transmission shaft, a pintle is pushed to complete injection, the traditional injection pump can operate the injection volume and the injection speed, but the injection pressure cannot be fed back, set and monitored aiming at nerve block anesthesia, especially when a large-capacity injector injects small-dose medicines, the injection pressure is high, potential nerve damage risks may exist, and in addition, the traditional injection pump cannot control the injection pressure and performs low constant pressure injection, so that the traditional injection pump has obvious defects in nerve block operation;

nerve block anesthesia needs two people cooperations under the ultrasonic guide of the past, and wherein the anesthesiologist is responsible for the puncture, and the anesthesia nurse is responsible for pushing away the medicine, but error and not enough often appear in both cooperations, consequently need use special instrument to assist the anesthesiologist one-man operation, convenient operation and control injection amount, the puncture needle that uses special design simultaneously makes things convenient for the anesthesiologist more accurate carry out the nerve around annotate the medicine anesthesia, therefore we provide a nerve block anesthesia device under the ultrasonic guide of one-man operation.

Through retrieval, patent publication No. CN211357315U discloses a nerve block injection kit under single operation ultrasonic guidance, including pjncture needle, connecting pipe and syringe, the syringe includes the cylinder and can be in the push rod of cylinder back-and-forth movement, the afterbody of pjncture needle is provided with the connector, the inside of connecting pipe head is provided with the second cork, the inside of connecting pipe afterbody is provided with the first cork, the connector can insert the second cork and connect on the connecting pipe, the head of cylinder can insert the first cork and connect on the connecting pipe, CN211357315U and most of these kind devices on the market can not single operation in the process of using in the prior art, lead to the complicacy and inconvenience of operation, need skilled double cooperation, occupy more manpower, and the pjncture needle is the straight puncture needle at present, can not effective location and injection straight blood vessel posterior nerve, in view of this we propose a nerve block anesthesia device under single operation ultrasonic guidance to solve current problem.
