Description

Anesthesia device for anesthesia department

Technical Field

The utility model relates to an operation anesthesia technical field especially relates to an anesthesia device for department of anesthesia.

Background

Anesthesia is generally performed on an operation patient through an anesthesia needle in an operation room at present, but the work of an anesthesiologist is extended to a recovery room or even an ICU immediately after the operation, and since the anesthesiologist is skilled in various nerve blocking technologies, patients naturally required to treat various pains gradually develop into a pain outpatient service. Anesthesiologists are no longer confined to performing anesthesia in operating rooms, and they often go to cardiac catheterization rooms, intracameral, radiology departments, and even medical wards to perform anesthesia for defibrillation of cardiac patients. Surgery is also subject to great variation. On the operating table, the surgeon only moves the knife in the diseased part, and the anaesthetist is more busy. The anesthesia depth of the patient is regulated and controlled, so that the patient is in a painless state, the smooth operation is ensured, and the anesthesia safety is ensured. In emergency situations (major intraoperative hemorrhage, etc.), it is busy plus busy. As an anesthesiologist, the pain of a patient is relieved, and important vital signs of the patient are managed, including respiration, heart rate, blood pressure, heart, nervous system, liver and kidney functions and the like. In general surgery, clinical anesthesia often requires registration of anesthetic drugs at the site to be operated, resulting in regional anesthesia. For example, larger wound sutures require anesthesia around the wound. While general syringes are usually used for injecting drugs during anesthesia, in case of open wounds, a single subcutaneous puncture point injects the drugs, and the diffusion time of the anesthesia is long.

Chinese patent (publication No. CN207341986U) discloses an anesthesia apparatus for anesthesia department, comprising: the anesthetic syringe comprises a syringe cylinder and an elastic protective sleeve wrapped on the outer side wall of the syringe cylinder, wherein the elastic protective sleeve is provided with a magic male tape and a magic female tape; the sterilizer, its with the connection can be dismantled to the anesthesia syringe, and pass through the public subsides of magic with the cooperation setting of the female subsides of magic is in one side of syringe cylinder, the sterilizer including the disinfectant section of thick bamboo that has the open end and with the size phase-match of open end and rotatable setting are in the ball of disinfectant section of thick bamboo open end, extend to the center department of this open end on the lateral wall of disinfectant section of thick bamboo open end and stretch out the pivot that two symmetries set up, set up on the ball and correspond in proper order and two pivot holes that match with two pivots.

The utility model provides an anesthesia department uses anesthesia device makes things convenient for medical personnel to disinfect and carry out the anesthesia injection to patient's the department of waiting to anaesthetize. However, the device provided by the above patent can only perform single-point anesthesia, and if the affected parts at different positions need to be anesthetized, the anesthesia can be completed only by applying needles at different positions for multiple times, which causes great pain to the patient, and the diffusion of the anesthetic is slow, and the workload of medical staff is increased.

Chinese patent (publication No. CN107198810A) discloses an injector structure, which comprises a syringe, a push rod and a needle, wherein one end of the push rod is provided with a rubber head, the other end is provided with a push handle, the rubber head is located inside the syringe, the needle is further provided with a plurality of through holes, the needle and the syringe are connected by plugging, the end of the needle is further provided with a sealing block, the through holes and the needle are integrally formed during manufacturing. The outer wall of the needle cylinder is provided with scale marks, a push handle, a rubber head and a push rod are integrally formed during manufacturing, and the push rod is connected with the needle cylinder in a piston manner. The volume of the syringe is 5-20 ml. When the anesthetic is injected subcutaneously, the anesthetic can be dispersed at multiple points, and the time required by anesthesia is shortened.

The syringe structure disclosed in the patent mainly simultaneously anaesthetizes affected parts at different depths in a single-point injection mode, but still has single point orientation diffusion in the transverse direction of open wounds, and cannot effectively shorten the time required for anaesthesia.

For easy understanding, the utility model provides an anesthesia device for department of anesthesia's use is: when using the utility model provides an during anaesthesia device, draw corresponding liquid medicine with a plurality of injection needle pipes earlier, the liquid medicine that a plurality of injection needle pipes drawn selects the dose of drawing according to actual need, when the user needs anaesthetize close many affected parts position, the user can driveslider 10 relative movement inslide 11 through the mode of stirringthird branch pole 8, as shown in figure 2 to can make the distance increase between firstinjection needle pipe 2 and secondinjection needle pipe 3 or thirdinjection needle pipe 13 and the secondinjection needle pipe 3 or reduce. Until the positions of the firstinjection needle tube 2, the secondinjection needle tube 3 and the thirdinjection needle tube 13 are relatively determined, the needles corresponding to the plurality of injection needle tubes are abutted against the drug application site, the index finger and the middle finger of a user are respectively placed on the lower end surface of theplate body 16, and pressure is gradually applied to enable theplate body 16 to move towards the direction close to theslide block 10 in a mode of compressing thespring 18, as the top end of therack 17 on theplate body 16 is abutted against the bottom end of theslide block 10, the pressure is continuously applied upwards, the top end of theslide block 10 is abutted against the inner wall of the slide way, theplate body 16 at the moment can be kept at the current position through the index finger and the middle finger, and therefore the movement trend of the slide. While the needle associated with the syringe tube has abutted against or partially injected into the body part, the relative friction between the two further limits the movement of the syringe tube relative to the injection site. The user then places his thumb on thefree end 12 of thefirst lever 5 and applies pressure gradually. The first supportingrod 5 is moved towards the direction of separating from the fixedframe 1 relative to the fixedframe 1, because the injection needle on the injection needle tube is inserted into the affected part, the relative displacement between the injection needle tubes is not caused when the first supportingrod 5 is pressed, the relative height position between the injection needle tubes and the affected part is fixed by the index finger and the middle finger of the user, and thepiston 15 gradually moves downwards along with the pressing of the thumb, thepiston 15 presses the fluid such as anesthetic in the injection needle tubes, so that the anesthetic enters the affected part through the injection needle tubes. The mode that one or a plurality of injection needle tubes are provided with the injection needles and the rest are not provided with the needles is selected to selectively perform anesthesia on single points or multiple points, so that the application range of the anesthesia device is expanded. When thefirst support rod 5 is pressed in the same step as the above step, thepiston 15 presses the fluid, such as air, in each syringe, so that the air in the syringe is evacuated, thereby facilitating the subsequent drawing of the liquid medicine by extracting thefirst support rod 5.

It should be noted that the above-mentioned embodiments are exemplary, and those skilled in the art can devise various solutions in light of the present disclosure, which are also within the scope of the present disclosure and fall within the scope of the present disclosure. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims.
