The epidural needle body module comprises a needle body and an optical probe, and the optical probe is fixed to the needle body and used for collecting images of the environment in front of the needle body. The optical tracking and positioning module comprises a positioning marker and an optical positioning camera, the positioning marker is fixed to the needle body, and the optical positioning camera is used for determining space pose information of the positioning marker. And the image processing and displaying module is connected with the optical probe and the optical positioning camera, and is used for generating an intra-spinal anesthesia puncture auxiliary image according to the image of the environment in front of the needle body and the spatial pose information of the positioning marker, and displaying the intra-spinal anesthesia puncture auxiliary image. According to the application, convenience is provided for epidural puncture through an optical visualization function, so that the success rate of epidural puncture is improved, and the operation difficulty and risk are reduced.

The invention provides an intelligent drug delivery method and system for pre-pump injection of m-hydroxylamine. The method comprises the following steps: determining an initial pumping rate, a target blood pressure range and a heart rate alarm threshold value of m-hydroxylamine according to initial information of a target patient; pre-pump injection of m-hydroxylamine is carried out according to the initial pump injection rate at a first preset time before lumbar anesthesia puncture operation; after the lumbar anesthesia puncture operation is completed, the current systolic pressure and the current heart rate of the target patient are collected based on the preset frequency; according to the current systolic pressure, the current heart rate, the target blood pressure range and the heart rate alarm threshold value, the initial pumping rate of m-hydroxylamine is adjusted; and carrying out pump injection of m-hydroxylamine based on the adjusted pump injection rate. By means of the method, pre-pumping injection is started before lumbar anesthesia puncture operation, occurrence of hypotension is preempted from the time dimension, the initial pumping injection rate is set based on information of a patient, the pumping injection rate is intelligently adjusted according to real-time feedback of the initial pumping injection rate, and therefore the occurrence rate of hypotension after cesarean section lumbar anesthesia is reduced.

The utility model relates to a continuous sacral plexus block suite. The continuous sacral plexus block suite comprises a puncture assembly and a drug delivery assembly, the puncture assembly comprises a sleeve, a steel needle, a first supporting steel wire, a hollow hard tube and a first isolation plug. The steel needle is arranged in the sleeve and extends outwards, so that one end of the steel needle can protrude out of the sleeve, and the other end of the steel needle is connected with the hollow hard tube; the steel needle is sleeved with the first supporting steel wire, and the first supporting steel wire is fixedly arranged in the sleeve; the first isolation plug is arranged at the top end of the hollow hard tube and is fixedly connected with the hollow hard tube; and the dosing assembly is arranged on the sleeve and is communicated with the sleeve. According to the scheme, the cannula can be placed at the sacral canal, the administration dosage and the administration frequency are dynamically adjusted according to the actual condition of a patient so that the cannula can be suitable for anesthesia or analgesia of a long-time operation, the applicability is high, practicability is high, the risk of total spinal anesthesia caused by one-time large-dose administration is effectively avoided, and safety is greatly improved.

The application discloses a continuous waist hard anesthesia catheter, relates to the technical field of medical devices, and comprises a catheter body and a flexible support frame body arranged in the catheter body. The catheter body comprises a head and a tube body part. A plurality of protrusions are connected between the head and the tube body part in the circumferential direction of the catheter body, so as to limit the head inserted into the spinal dura mater. The flexible support frame body is used for supporting the tube wall of the catheter body to be radially scaled, so that the catheter body can be transformed between an expansion state relative to an initial state and a contraction state relative to the initial state. The flexible support frame body comprises a center frame body and a plurality of support frame bodies. The center frame body extends along the length direction of the catheter body, and the plurality of support frame bodies are connected between the center frame body and the catheter body in the circumferential direction of the center frame body. The catheter body lumen can be divided into a plurality of independent chambers. Each independent chamber is provided with a corresponding medicine outlet, so that the medicine liquid output by the head inserted into the spinal dura mater and the medicine liquid output by the tube body part are shunted.

A support and positioning device used for spinal anesthesia procedure includes a body, an arm rest, a chin rest, and a handle. The arm rest and / or chin rest may be removably attached to the body. Moreover, the arm rest and the chin rest may be adjustable in height and manufactured in varied sizes and shapes. In some embodiments, the handle comprises two hand straps with adjustable height. The support device may also comprise a disposable or washable outer cover with a waterproof zipper, such that the outer cover can be removed from the body to allow for easy disinfection and reuse of the support device in hospital or other health care settings.

The utility model provides an interspinous ligament puncture single-time spinal anesthesia guide needle which comprises a handle and a needle tube, the top end of the needle tube is fixedly connected with the bottom end of the handle, and a chamfer hole is formed in the inner side of the top end of the needle tube; and a plurality of groups of scale marks are arranged on the outer side of the needle tube at equal intervals. The chamfering hole is formed in the inner side of the top end of the needle tube, so that the lumbar anesthesia needle can be conveniently, quickly and smoothly inserted and is not prone to being blocked during use, the insertion efficiency of the lumbar anesthesia needle can be effectively improved, and the operation difficulty can be effectively reduced; the multiple sets of scale marks are arranged on the outer side of the needle tube, so that the puncture depth of the needle tube can be conveniently and rapidly measured during puncture, medical staff can conveniently know the puncture depth in time, and the operation accuracy is improved.

The invention relates to an intra-spinal anesthesia puncture guiding device and method, and belongs to the technical field of intra-spinal anesthesia puncture guiding instruments. The intraspinal anesthesia puncture guide device comprises a control seat, a leaning pad and a plurality of supporting legs, the leaning pad is fixedly mounted at the bottom of the control seat, and the supporting legs are fixedly mounted at the bottom of the leaning pad; after the device is attached to the lower back of a patient, the two probing arms can generate displacement changes along with fluctuation of spinous processes through the positioning assembly so as to assist in determining the centerline position of a spinal canal, point position marking is conducted on an intervertebral space through the marking component at the centerline position, and a clear puncture reference is formed; the guiding assembly is aligned with the marked position, the device is fixed, the determined midline and intervertebral space positions are kept, then the needle inserting direction of the anesthesia puncture needle is axially limited and guided through the guiding assembly, and the puncture needle enters along a preset path.
