Dosage accurate control-type anesthesia outfit

[0055] In Embodiment 2, on the basis of Embodiment 1, the first gear transmission device includes a fifth gear 20 that is coaxially rotatably mounted on the case 1 with the fourth gear 11, and the fifth gear 20 is meshed and rotatably mounted on the case. The sixth gear 21 on the body 1, the sixth gear 21 is coaxially rotatably installed with a first pulley 22 and the first pulley 22 is fitted with a first belt 23, and the other end of the first belt 23 is fitted with a rotatably installed The second pulley 24 and the second pulley 24 on the box 1 are coaxially rotatably installed with a seventh gear 25 meshing with the double-sided rack 9.

[0056] When using this embodiment, refer to the attached figure 2 As shown, we have a fourth gear 11 rotatably installed on the box body 1 and a fifth gear 20 is also coaxially rotatably installed on the lower end of the fourth gear 11, and the fifth gear 20 is meshed with a rotating device mounted on the box body 1. The sixth gear 21, the radius of the sixth tooth 21 is smaller than the fifth gear 20, refer to the attached Picture 11 As shown, we coaxially rotate and install a first pulley 22 on the lower end of the sixth gear 21 on the box 1 and the first pulley 22 is matched with a first belt 23. Figure 13 As shown, we fit the other end of the first belt 23 with a second pulley 24 that is rotatably installed on the upper end of the box 1, and the box 1 is also provided with a seventh gear 25 that is rotatably installed coaxially with the second gear 3. The seventh gear 25 meshes with the double-sided rack 9. The fifth gear 20 and the sixth gear 21 are arranged to increase the transmission ratio between the fourth gear 11 and the double-sided rack 9 so that the double-sided rack 9 slides. The longer the distance makes the time for the medicine mixing device to stir the medicine longer, so that the medicine mixing effect is better. Although the transmission ratio can also be increased through the belt transmission, when the belt transmission increases the transmission ratio, the pulley gear will become larger. The space occupied by the box 1 becomes larger, which is likely to cause obstacles to other structures, and never affects the transmission effect. For this reason, increasing the volume of the box 1 will make the anesthesia device occupy a larger space, making the anesthesia device unsuitable for movement and placement;

[0057] In the initial state, the fourth gear 11 is disengaged from the sector gear 2. When the sector gear 2 is disengaged from the first gear 8, it meshes with the fourth gear 11 and drives the fourth gear 11 to rotate. Then the fourth gear 11 rotates coaxially with the fourth gear 11. The fifth gear 20 will drive the sixth gear 21 to rotate. At this time, the fifth pulley 61 that rotates coaxially with the sixth gear 21 starts to rotate and the fifth pulley 61 drives the sixth pulley 64 to rotate through the first belt 23, and then Drives the seventh gear 25 that rotates coaxially with the sixth pulley 64 to rotate, and then the seventh gear 25 drives the double-sided rack 9 to start sliding, thereby driving the medicament mixing device to start, so that the medicament starts to be stirred to accelerate the mixing, and in the first The fourth gear 11 is reversed under the action of the torsion spring 10, so that the entire first gear transmission device starts to reverse, so that the double-sided rack 9 is reset, so that the medicine mixing device is started again, and the medicine is stirred again.

[0058] In Embodiment 3, on the basis of Embodiment 1, the medicine mixing device includes a cylinder 26 fixedly connected with a plurality of medicine cylinders 7 and a circular ring 27 is rotatably installed in the cylinder 26, and the outer surface of the circular ring 27 surrounds A first tooth system 28 is provided and the first tooth system 28 meshes with the double-sided rack 9. A number of fan blades 74 are fixed coaxially in the ring 27, and the lower end of the ring 27 is rotatably fitted and fixedly installed The duct 29 on the box body 1 and the other end of the duct 29 are connected to the squeeze cylinder 16, and the first sector plate 14 can realize the connection or disconnection between the control ring 27 and the duct 29.

[0059] When using this embodiment, refer to the attached Figure 24 As shown, the medicament mixing device includes a cylinder 26 and the cylinder 26 is a double-layer ring structure. The cross-sectional size of the gap between the two layers of rings is the same as that of the ring 27, so that the ring 27 can be opposed to the cylinder 26 in this gap. Rotates, and the inner structure of the cylinder 26 is fixedly connected to the corresponding medicament cylinder 7 through a number of pipes. This structure plays a sealing role. Figure 26 As shown, a first tooth system 28 is arranged on the outer circumferential surface of the ring 27 at intervals, and the first tooth system 28 meshes with the double-sided rack 9 (the first tooth system 28 and the seventh gear 25 respectively engage with double-sided teeth When the seventh gear 25 drives the double-sided rack 9 to slide longitudinally on the box 1, the double-sided rack 9 will simultaneously drive the ring 27 to rotate through the first tooth system 28. A number of fan blades 74 fixed coaxially in the ring 27 will rotate with the ring 27. The box body 1 is fixedly installed with a pipe 29 and the upper end of the pipe 29 rotates with the lower end of the ring 27. Refer to the attachment Figure 25 As shown, the duct 29 is provided with a slit 75 corresponding to the first sector plate 14. The upper and lower wall dimensions of the slit 75 are the same as the thickness of the first sector plate 14 and the first sector plate 14 and the slit 75 are in sliding fit, and the duct 29 A circular table 79 with a central hole 80 is provided at the upper end of the trough 75. The lower end surface of the circular trough 79 and the upper wall of the trough 75 are in the same plane. The first fan-shaped plate 14 and the lower end surface of the circular table 79 are also in sliding fit. The function of 14 is to prevent the medicine from flowing out of the central hole 80 when the medicine mixing device mixes medicine, so that the sliding of the first fan-shaped plate 14 can control the flow of medicine, and the upper end surface of the circular table 79 is inclined (the angle of inclination is small) , To prevent the medicament from being too large to make the medicament in the cavity formed by the inclined surface, so that only a small part of the medicament is in contact with the fan blade 74, thereby affecting the mixing effect), so that the medicament is gathered in the direction of the central hole 80, and we are still in the catheter There is a leakage plugging device inside 29, a third spring 78 is fixedly installed on the part of the lower wall of the trough 75 of the duct 29, and the third spring 78 is connected with a wedge ring 77 slidingly fitted with the duct 29. In the initial state, the first sector plate 14 blocks the central hole 80 and the wedge ring 77 is pressed by the first sector plate 14, so that the third spring 78 is compressed. When the first sector plate 14 is forced to rotate and disengage the duct 29, the action of the third spring 78 The wedge ring 77 slides vertically so that the tip of the wedge ring 77 contacts the lower end surface of the circular table 79, so that the duct 29 is in a sealed state, preventing the leakage of medicine or external dust from entering the duct 29.

[0060] In Embodiment 4, on the basis of Embodiment 1, a first one-way bevel gear 30 arranged coaxially with the sector gear 2 is rotatably mounted on the case 1, and the first one-way bevel gear 30 and the sector gear 2 are rotatably mounted The first one-way bevel gear 30 engages with a second bevel gear 31 rotatably mounted on the housing 1 and the second bevel gear 31 is coaxially rotatably mounted with a third bevel gear 32. The three bevel gear 32 is meshed with a fourth bevel gear 33 rotatably mounted on the casing 1 and the fourth bevel gear 33 is driven by a motor 34.

[0061] When using this embodiment, refer to the attached Figure 7 As shown, the lower end of the sector gear 2 is coaxially mounted with a first one-way bevel gear 30, in order to prevent the first one-way bevel gear 30 from rotating with the sector gear 2 when the anesthetic dose is adjusted, that is, when the handle 59 is turned, thereby driving other The rotation of the device changes the initial position of each device, which affects the use effect of the anesthesia device. We have a second ratchet tooth 72 on the end face of the first one-way bevel gear 30, and the second ratchet tooth 72 is matched with a second pawl 71 In addition, the second pawl 71 rotates and cooperates with the box body 1. In order to make the second pawl 71 always fit the second ratchet teeth 72, we have a second elastic block 73 between the second pawl 71 and the box body 1. Only when the first one-way bevel gear 30 rotates in one direction, the second pawl 71 will resist the second ratchet teeth 72 so that the second single-row bevel gear starts to rotate, and when the anesthetic dose is adjusted and the handle 59 is turned, the first single The first one-way bevel gear 30 does not rotate. The first one-way bevel gear 30 is meshed with a second bevel gear 31 and the second bevel gear 31 is coaxially installed with a third bevel gear 32 on the side close to the extrusion cylinder 16. The three bevel gear 32 meshes with the fourth bevel gear 33 and the fourth bevel gear 33 is driven by the motor 34 fixedly mounted on the housing 1. Refer to the attachment Figure 29 As shown, the second rotating shaft 70 connecting the sector gear 2 to the first rotating shaft 69 and the first one-way bevel gear 30 is in an axial sliding fit. Before adjusting the arc length of the sector gear 2 and the first gear 8 (after turning the handle 59 before turning the sector gear 2), we use the handle 59 to pull the first shaft 69 to slide axially, so that the sector gear 2 is separated from the first gear 8, and we have a blocking round table 68 below the dial 58. In the initial state, blocking The round table is at a distance from the lower end of the box body 1, and the dial 58 is in contact with the box body 1. When the first rotating shaft 69 is pulled up, the first rotating shaft 69 is still not in contact with the second rotating shaft 70. When the dial 58 is adjusted according to the patient’s condition at this time, the first gear 8 will not be driven to rotate (the dial 58 and the handle 59 are both fixed on the end of the first rotating shaft 69 protruding from the box), in order to avoid sector gears 2 When resetting, it collides with the first gear 8. We set the sector gear 2 and the first gear 8 to dense and fine teeth, so that if the sector gear 2 cannot accurately mesh with the first gear 8 when reset, we It can also be adjusted appropriately. Because the two teeth are relatively fine, the impact on the measurement during the adjustment process is very small and can be ignored. At this time, the upper cover of the box 1 needs to be made transparent, so that during the adjustment process It is better to observe in the middle.
