Description
The technical field is as follows:
the utility model relates to medical equipment, in particular to an epidural anesthesia pressure detection and injection system.
The background art comprises the following steps:
epidural anesthesia (also known as epidural block): the traditional Chinese medicine composition is one of anesthesia techniques widely applied to clinic, and has the characteristics of small influence on cardiovascular, respiratory and gastrointestinal functions, exact analgesic effect, good muscle relaxation, economy and practicality, and has no replaceable effect in clinic anesthesia and pain treatment. Epidural anesthesia scope: the operation anesthesia, postoperative analgesia, delivery analgesia and pain treatment of neck, chest, abdomen, waist bottom, perineum, lower limbs and feet are combined with general anesthesia at present for major operations of chest and abdomen and the like.
The epidural anesthesia comprises two links of epidural space puncture and epidural space catheter placement.
After the epidural space puncture is finished, before epidural injection, an epidural space test method is often used for using toxic reaction of anesthetic to serve as a secondary monitoring method for positioning of the epidural space puncture and catheter placement, however, if the epidural space puncture and catheter placement are wrong, for example, the catheter is mistakenly inserted into a subarachnoid space or a blood vessel, serious complications can be caused, and when local anesthetic with an epidural anesthetic dose is mistakenly injected into the subarachnoid space, total spinal anesthesia can be immediately generated (namely, all somatic nerves and sympathetic nerves are blocked in a short time, namely, breathing and heartbeat are stopped, and consciousness disappears); when the local anesthetic with the epidural anesthetic dose is mistakenly injected into a blood vessel, mild or severe local anesthetic toxic reaction (sudden convulsion , consciousness loss, high muscle tension, muscle tremor and respiratory heartbeat stoppage) caused by intravascular injection, local anesthetic systemic toxic reaction caused by epidural space bleeding (the incidence rate is about 9.6-25.9 percent) and total spinal anesthesia can be caused, and when the local anesthetic is not timely found and effectively treated, the patient can be disabled or die.
Meanwhile, the epidural space has abundant vascular plexus, the epidural space catheter can damage the venous plexus to bleed, epidural hematoma is easy to generate after bleeding, and irreversible injury can be generated once the epidural hematoma forms to press the spinal cord for more than 24 hours. The diagnosis of epidural hematoma mainly depends on clinical symptoms, physical signs and imaging examination, once the diagnosis is confirmed, the operation must be performed within 6-8 h, hematoma is cleared, and the compression is relieved. Spinal irreversible damage is avoided, and the prognosis is poor when the spinal compression exceeds 8 h.
The blind detection method has no anesthesia complications caused by epidural external tube hemorrhage and the like due to objective indications, and is still the main source of epidural anesthesia complications and epidural anesthesia accidents.
The utility model has the following contents:
the utility model aims to provide an epidural anesthesia pressure detection medicine injection system for detecting epidural anesthesia catheter positioning and automatically feeding medicine.
The utility model is implemented by the following technical scheme: the epidural anesthesia pressure detection medicine injection system comprises a two-channel injection pump and a detection medicine injection catheter; the detection medicine injection guide pipe comprises a main guide pipe, two liquid inlet branch pipes and a negative pressure sampling branch pipe; one end of each of the two liquid inlet branch pipes is respectively in split movable insertion connection with the corresponding two liquid outlets of the two-channel injection pump; one end of each of the two liquid inlet branch pipes is communicated with one end of the main pipe; the other end of the main catheter is provided with a catheter quick connector; a check valve is arranged on the main conduit; a pressure detection device is arranged on the main conduit between the liquid inlet branch pipe and the check valve; the negative pressure sampling branch pipe is arranged on the main conduit between the check valve and the conduit quick connector; a block valve is arranged on the negative pressure sampling branch pipe; the top end of the negative pressure sampling branch pipe is provided with a bottle stopper puncture outfit.
Preferably, the two liquid inlet branch pipes are connected with the main pipe through an electric control three-way valve; the electric control three-way valve and the double-channel injection pump are respectively electrically connected with a controller.
Preferably, the block valve is an electric control block valve; the electric control block valve and the double-channel injection pump are respectively electrically connected with a controller.
