Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia devices, in particular to a concentration-adjustable anesthesia device. Background Art

[0002] Anesthesiology is an important part of today's medical field. Before almost all surgeries, patients need to undergo general anesthesia or local anesthesia to reduce their pain during the operation. However, the anesthesia devices currently used by anesthesia departments are generally disposable. Once the effectiveness of the anesthetic weakens during the operation, anesthesia needs to be performed again, which is very troublesome.

[0003] During the use of existing devices, there is room for improvement in the mixing effect of anesthetics and injection drugs, which can easily lead to a reduction in the anesthetic effect and cannot achieve sufficient mixing of anesthetics at a low cost; the existing devices need to control the amount of anesthetic added through a valve when adjusting the amount of anesthetic added. When the valve is loose, it is easy to cause deviations in the amount of addition, which can easily lead to medical accidents. Summary of the Invention

[0004] In view of this, the present invention provides a concentration-regulated anesthesia device, which solves the problem that during the use of existing devices, the mixing effect of anesthetic agents and injection agents needs to be improved, which easily leads to a reduction in the anesthetic effect and cannot achieve sufficient mixing of anesthetic agents at a low cost; the existing device needs to control the amount of anesthetic added by a valve when adjusting the amount of anesthetic added. When the valve is loose, it is easy to cause deviations in the amount of addition, which can easily lead to medical accidents.

[0005] The purpose and efficacy of the concentration-regulated anesthesia device of the present invention are achieved by the following specific technical means: The present invention provides a concentration-adjustable anesthesia device, which specifically comprises a base; a first mixing part is installed on the base.

[0006] Furthermore, the first mixing part is composed of a mounting block, an electric cylinder, a mixing barrel, a cover plate, a first liquid inlet pipe, a second liquid inlet pipe, a valve, a rubber sleeve and an auxiliary rod. The mounting block is welded to the top surface of the base. The mounting block is a rectangular block structure. An electric cylinder is fixed to the left end face of the mounting block, and a mixing barrel is fixed to the left end face of the electric cylinder.

[0007] Furthermore, a cover plate is buckled on the top of the mixing barrel, and the cover plate has a stepped structure. The outer wall of the lower half of the cover plate contacts the inner wall of the mixing barrel, the step of the cover plate contacts the top surface of the mixing barrel, and the outer diameter of the upper half of the cover plate is larger than the outer diameter of the mixing barrel.

[0008] Furthermore, a first liquid inlet pipe and a second liquid inlet pipe are installed on the cover plate, the first liquid inlet pipe is connected to the injection drug pipeline, and the second liquid inlet pipe is connected to the anesthetic pipeline. A valve is installed on the first liquid inlet pipe and the second liquid inlet pipe, and a rubber sleeve is adhered to the valve stem of each valve, and the rubber sleeve is a ring-shaped structure, which serves as an anti-slip part when the valve stem is adjusted; an auxiliary rod is welded on each valve, and the auxiliary rod is a cylindrical rod-shaped structure, and the outer wall of the auxiliary rod is in elastic contact with the outer wall of the rubber sleeve. When adjusting the valve, hold the rubber sleeve on the valve stem with your hand, and the rubber sleeve can play an anti-slip role when rotating the valve stem. After adjustment, the elastic pressure of the auxiliary rod on the rubber sleeve can prevent the valve stem from loosening, thereby affecting the amount of anesthetic added.

[0009] Furthermore, a second mixing part is installed on the cover plate, and the second mixing part consists of a motor, a rotating shaft and an impeller. The motor is fixed on the top surface of the cover plate, and a rotating shaft is installed on the rotating shaft of the motor. Three impellers are installed on the rotating shaft. The three impellers are all located inside the mixing barrel. During mixing, the motor is started, and when the motor drives the rotating shaft and impeller to rotate, the rotation of the impeller can achieve mixing of the injectable drug and the anesthetic.

[0010] Furthermore, a first auxiliary part is installed in the mixing barrel, and the first auxiliary part consists of a first seat body, a first spring rod, a first mixing plate, a through hole and an extrusion rod. The first seat body is welded inside the mixing barrel. The first seat body is a ring structure. Two first spring rods are symmetrically welded to the top end of the first seat body. The upper end of the two first spring rods is an extended end, and the extended ends above the two first spring rods are welded to the bottom end surface of the first mixing plate.

[0011] Furthermore, the first mixing plate is a circular plate-like structure, and through holes are opened on the first mixing plate in a ring array, and the through holes are circular hole-like structures; two extrusion rods are symmetrically welded to the bottom end surface of an impeller in the middle, and the two extrusion rods are cylindrical rod-like structures, and the lower ends of the two extrusion rods are polished. After polishing, the lower ends of the two extrusion rods are arc-shaped structures, and the lower ends of the two extrusion rods are elastically connected to the through holes. When the impeller rotates, the first mixing plate rotates up and down. While the motor rotates to drive the impeller to rotate to achieve mixing, auxiliary mixing can be achieved by continuous extrusion of the first mixing plate by the extrusion rods.

[0012] Furthermore, a second auxiliary part is installed in the mixing barrel, and the second auxiliary part consists of a second base body, a second spring rod, a second mixing plate, a force-bearing arm, a frame body and a protrusion. The second base body is fixed inside the mixing barrel. The second base body is a ring structure. Two second spring rods are symmetrically welded to the top of the second base body. The upper ends of the two second spring rods are protruding ends, and the upper ends of the two second spring rods are fixed to the second mixing plate.

[0013] Furthermore, the second mixing plate is a circular plate structure, and a force-bearing arm is welded on the top surface of the second mixing plate, and the force-bearing arm is a bent rod structure, and the force-bearing arm passes through the cover plate; a frame is welded on the top surface of the base, and a protrusion is welded on the bottom end surface of the frame in a linear array, and the protrusion is a semi-cylindrical structure. The bottom end surface of the force-bearing arm contacts the frame, and when the mixing barrel moves to the left, the force-bearing arm elastically contacts the protrusion. While the electric cylinder reciprocates and extends to drive the mixing barrel to reciprocate to achieve mixing, the force-bearing arm can achieve up and down reciprocating motion by continuously squeezing the force-bearing arm by the protrusion. At this time, the second mixing plate reciprocates up and down. When the second mixing plate reciprocates up and down, the liquid in the mixing barrel can be mixed again.

[0014] Furthermore, two support blocks are symmetrically welded on the bottom end surface of the base. Both support blocks are rectangular block structures. The two support blocks together constitute the support structure of the base. When the two support blocks are in contact with the placement table, the distance between the bottom end surface of the base and the placement table is 10 cm. When transferring the position, the fingers can be directly inserted into the bottom of the base, which makes it convenient to pick up the device and also facilitate the transfer.

[0015] Furthermore, a water pump is installed in the mixing barrel, and a liquid inlet pipe and a liquid discharge pipe are provided on the water pump. The liquid inlet pipe and the liquid discharge pipe of the water pump are both located inside the mixing barrel. When mixing is required, the water pump can be directly controlled to work. At this time, the liquid discharged from the water pump discharge pipe can achieve auxiliary mixing of the liquid in the mixing barrel. Beneficial effects

[0016] A second mixing part and a first auxiliary part are provided. Through the provision of the second mixing part and the first auxiliary part, on the one hand, the liquid in the mixing barrel can be mixed by rotating the impeller driven by the motor; on the other hand, while the impeller rotates to achieve mixing, the first mixing plate can be continuously squeezed by the extrusion rod to achieve the up and down reciprocating motion of the first mixing plate, thereby achieving re-mixing of the liquid in the mixing barrel, improving the mixing effect, and having high practicality.

[0017] A first mixing part and a second auxiliary part are provided. Through the arrangement of the first mixing part and the second auxiliary part, on the one hand, the reciprocating extension and retraction of the electric cylinder can drive the mixing barrel to reciprocate left and right. When the mixing barrel reciprocates left and right, auxiliary mixing of the liquid in the mixing barrel can be achieved; on the other hand, when the mixing barrel reciprocates left and right, the up and down reciprocating movement of the second mixing plate can be achieved through the continuous squeezing of the force-bearing arm by the protrusion. At this time, the liquid in the mixing barrel is mixed again. Multiple mixing of the liquid in the mixing barrel can be achieved without too many electric components, and the practicality is high.

[0018] A water pump is provided, through which the liquid in the mixing barrel can be pumped out and discharged to the inner wall of the mixing barrel, thereby achieving efficient mixing of the anesthetic and the injection liquid.

[0019] A rubber sleeve and an auxiliary rod are provided. Through the setting of the rubber sleeve and the auxiliary rod, on the one hand, the rubber sleeve can avoid slipping when adjusting the valve stem, thereby ensuring the accuracy of adjustment; on the other hand, after the valve stem is adjusted, the auxiliary rod squeezes the rubber sleeve to prevent the valve stem from loosening, thereby ensuring the accuracy of filling.
