A drug delivery anesthesia device

Abstract

This invention discloses a drug delivery anesthesia device, comprising a drug delivery tube, an oxygen tube, and a mask. The oxygen tube is directly and fixedly connected to a mixing tube. An inner tube is fixedly connected to the end of the mixing tube furthest from the oxygen tube, penetrating one side of the inner wall of the mixing tube. The end of the inner tube furthest from the oxygen tube is fixedly connected to the mask. The advantage is that when the detector detects a deep breath from the patient, it activates a push rod, causing the elastic rod to move to the right. The friction wheel and the conical roller abut at their larger diameter points. Since the motor speed is constant, the friction wheel's speed increases, thereby increasing the speed of the connecting disc, which in turn increases the speed of the embedded ring, further increasing the speed of the drive disc, and ultimately increasing the speed of the fan. This means that when the patient takes a deep breath, the fan speed increases, not only attracting the patient's attention but also encouraging deep breathing, thus accelerating the anesthesia process.

Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a drug delivery and anesthesia device. Background Technology

[0002] Inhalation anesthesia involves delivering an anesthetic agent into the patient's alveoli through respiration, causing the anesthetic gas to diffuse into the bloodstream and thus inhibit the central nervous system, thereby anesthetizing the patient. Because inhalation anesthesia is simple to administer, has low risk, and is virtually painless during delivery, it is currently the most common method of anesthesia.

[0003] However, although inhalation anesthesia is painless, patients are often uncooperative during administration due to their fear of the unfamiliar environment and the administration equipment, frequently crying and making a fuss. This severely affects the effectiveness and efficiency of the administration. Furthermore, without proper guidance, the air inside the mask becomes very turbid due to crying during administration, and repeated inhalation by the patient can easily cause discomfort. Additionally, without proper guidance, medical staff may not assist patients in using the anesthesia mask, and parents may even force the patient to use it, which can easily leave the patient with negative memories. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by providing a drug delivery anesthesia device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drug delivery anesthesia device, comprising a drug delivery tube for delivering anesthetic drugs, an oxygen tube, and a mask, wherein the oxygen tube is directly and fixedly connected to a mixing tube, and an inner tube is fixedly connected to the end of the mixing tube away from the oxygen tube, the inner tube penetrating one side of the inner wall of the mixing tube, and the end of the inner tube away from the oxygen tube is fixedly connected to the mask.

[0006] A transparent cover is fixedly connected to the upper wall of the mixing tube near the oxygen tube. The upper end of the transparent cover is fixedly connected to the medicine tube, and the end of the medicine tube inside the transparent cover is vertically downward. A medicine inlet hole is opened on the side wall of the mixing tube and is directly connected to the transparent cover. A fan is rotatably connected inside the transparent cover and is located directly below the medicine tube.

[0007] In the aforementioned drug delivery anesthesia device, the inner wall of the mixing tube is rotatably connected to multiple rotating rings, the inner wall of each rotating ring is fixedly connected to multiple inclined plates, and the outer wall of each rotating ring is fixedly connected to multiple magnetic blocks. An inner shaft is embedded in the lower wall of the mixing tube, and the inner shaft can rotate along its own axis. A drug-uniforming wall hole is opened in the lower wall of the mixing tube, and a power box is fixedly connected to the lower outer wall of the mixing tube. A power device is installed in the power box, and the power device is connected to the inner shaft through the drug-uniforming wall hole.

[0008] In the aforementioned drug delivery and anesthesia device, the power unit includes a motor, the output end of which is fixedly connected to an active disc, the side wall of which passes through a uniform drug wall hole and abuts against an inner shaft.

[0009] In the aforementioned drug delivery and anesthesia device, an embedded ring is embedded in the inner wall of the mixing tube, and an interesting wall hole is opened on the upper and lower parts of the side wall of the mixing tube. The interesting wall hole on the upper side is located below the windmill. A drive disk is rotatably connected to the inner wall of the transparent cover through a pin. The end face of the drive disk abuts against the side wall of the windmill, and the side wall of the drive disk abuts against the embedded ring through the interesting wall hole on the upper side.

[0010] In the aforementioned drug delivery anesthesia device, the lower interesting wall hole is connected to the power component through a connecting assembly. Multiple return tubes are connected through the side wall of the inner tube. One end of the return tube is connected to the outer wall of the inner tube near the mask side, and the other end of the return tube is connected to the inner tube near the oxygen tube side. The end of the inner tube near the oxygen tube side is set in a concave shape.

[0011] In the aforementioned drug delivery anesthesia device, the connecting assembly includes a linkage plate rotatably connected to the inner wall of the power box via a pin shaft. The central shaft of the linkage plate is connected to a universal joint, and the universal joint is connected to a speed change assembly. A detector is provided on the mask, and the detector can detect the patient's respiratory status.

[0012] In the aforementioned drug delivery anesthesia device, the connecting assembly includes a linkage plate rotatably connected to the inner wall of the power box via a pin shaft. The central shaft of the linkage plate is connected to a universal joint, and the universal joint is connected to a speed change assembly. A detector is provided on the mask, and the detector can detect the patient's respiratory status.

[0013] In the aforementioned drug delivery anesthesia device, a push rod is fixedly connected to the inner upper wall of the mixing tube, and the output end of the push rod is fixedly connected to an elastic rod. Multiple magnetic segments are provided on the inner shaft, and each magnetic segment is located directly below each rotating ring. The size of the magnetic blocks on each rotating ring is different.

[0014] Compared with existing technologies, the advantages of this invention are:

[0015] 1. In this application, the motor in the power box drives the active disk to rotate, which in turn drives the inner shaft to rotate. The rotation of the inner shaft causes the magnetic segment on it to rotate, which in turn drives the rotating ring to rotate through magnetic force. The rotation of the rotating ring drives the inclined plate to rotate. As the oxygen and medicine move to the right, they collide with the inclined plate and flow more chaotically, achieving further mixing.

[0016] 2. When the detector detects a patient taking a deep breath, it initiates the push rod movement, causing the elastic rod to move to the right. The friction wheel and the conical roller, with the larger diameter, come into contact. Since the motor speed is constant, the speed of the friction wheel increases at this time, which in turn increases the speed of the connecting disc, drives the speed of the embedded ring to increase, and then increases the speed of the drive disc, ultimately increasing the speed of the windmill. This means that when the patient takes a deep breath, the windmill speed increases, which not only attracts the patient's attention but also encourages the patient to take a deep breath, thus accelerating the entire anesthesia process.

[0021] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] Example

[0023] Reference Figure 1-3An anesthesia delivery device includes a drug delivery tube 1, an oxygen tube 2, and a mask 3. The oxygen tube 2 is directly connected to a mixing tube 5. An inner tube 6 is fixedly connected to the end of the mixing tube 5 furthest from the oxygen tube 2. The inner tube 6 penetrates one side of the inner wall of the mixing tube 5, and the end of the inner tube 6 furthest from the oxygen tube 2 is fixedly connected to the mask 3. A transparent cover 4 is fixedly connected to the upper wall of the mixing tube 5 near the oxygen tube 2. The upper end of the transparent cover 4 is fixedly connected to the drug delivery tube 1, and the end of the drug delivery tube 1 inside the transparent cover 4 is vertically downward. A drug inlet 7 is opened on the side wall of the mixing tube 5, directly communicating with the transparent cover 4. A fan 15 is rotatably connected inside the transparent cover 4, and the fan 15 is located directly below the drug delivery tube 1. In use, the mask 3 is placed over the patient's face, and anesthetic drugs and oxygen are supplied to the drug delivery tube 1 and the oxygen tube 2. The anesthetic drugs enter the mixing tube 5 through the transparent cover 4 and the drug inlet 7, mix with the oxygen, and then enter the inner tube 6 through the return tube 8, finally exiting from the mask 3 to the patient.

[0024] Multiple rotating rings 10 are rotatably connected to the inner wall of the mixing tube 5. Multiple inclined plates 13 are fixedly connected to the inner wall of the rotating rings 10. Multiple magnetic blocks 12 are fixedly connected to the outer wall of each rotating ring 10. An inner shaft 11 is embedded in the lower wall of the mixing tube 5. The inner shaft 11 can rotate along its own axis. A drug-mixing wall hole 20 is opened in the lower wall of the mixing tube 5. A power box 9 is fixedly connected to the lower outer wall of the mixing tube 5. A power device is installed in the power box 9. The power device is connected to the inner shaft 11 through the drug-mixing wall hole 20. First, after the medicine enters the transparent cover 4, it will directly blow the fan 15 to rotate, thereby attracting the patient's attention. After the oxygen is directly mixed with the oxygen tube 2 in the mixing tube 5, it tends to move directly to the right, thereby colliding with the end of the inner tube 6. Since the end of the inner tube 6 is concave, the oxygen will flow back under the action of the arc surface, thereby colliding with the medicine to produce a more thorough mixture. Then, it enters the inner tube 6 through the return tube 8 and is finally output to the patient from the mask 3.

[0025] The power unit includes a motor 18, the output end of which is fixedly connected to an active disk 19. The side wall of the active disk 19 passes through a uniform wall hole 20 and abuts against the inner shaft 11. An embedded ring 17 is embedded in the inner wall of the mixing tube 5. An interesting wall hole 28 is opened on the upper and lower parts of the side wall of the mixing tube 5. The upper interesting wall hole 28 is located below the windmill 15. A drive disk 16 is rotatably connected to the inner wall of the transparent cover 4 via a pin. The end face of the drive disk 16 abuts against the side wall of the windmill 15, and the side wall of the drive disk 16 abuts against the embedded ring 17 through the upper interesting wall hole 28. In this application, the motor 18 in the power box 9 drives the active disk 19 to rotate, thereby driving the inner shaft 11 to rotate. The rotation of the inner shaft 11 causes the magnetic segment 14 on it to rotate, thereby driving the rotating ring 10 to rotate through magnetic force. The rotation of the rotating ring 10 drives the inclined plate 13 to rotate. As the oxygen mixed with the medicine moves to the right, it collides with the inclined plate 13 and flows more chaotically, achieving further mixing.

[0026] The lower fun wall hole 28 is connected to the power component via a connecting assembly. Multiple return tubes 8 are connected through the side wall of the inner tube 6. One end of the return tube 8 is connected to the outer wall of the inner tube 6 near the mask 3, and the other end of the return tube 8 is connected to the side of the inner tube 6 near the oxygen tube 2. The end of the inner tube 6 near the oxygen tube 2 is concave. After the medicine enters the transparent cover 4, it will directly blow the fan 15 to rotate, thereby attracting the patient's attention. After the oxygen is directly mixed with the oxygen tube 2 and the mixing tube 5, the oxygen tends to move directly to the right, thus colliding with the end of the inner tube 6. Since the end of the inner tube 6 is concave, the oxygen will flow back under the action of the arc surface, thereby colliding with the medicine to produce a more thorough mixture. Then, it enters the inner tube 6 through the return tube 8 and is finally output to the patient from the mask 3.

[0027] The connecting assembly includes a connecting disc 26 rotatably connected to the inner wall of the power box 9 via a pin. A universal joint 27 is connected to the central axis of the connecting disc 26, and a speed change assembly is connected to the universal joint 27. A detector 29 is installed on the mask 3, which can detect the patient's respiratory status. The speed change assembly includes a conical roller 21, which is coaxially and fixedly connected to the drive disc 19. An elastic rod 24 is slidably connected to the upper inner wall of the power box 9. A wheel frame 23 is fixedly connected to the lower end of the elastic rod 24. A friction wheel 22 is rotatably connected to the wheel frame 23, and the friction wheel 22 abuts against the conical roller 21. The central axis of the friction wheel 22 is connected to the universal joint 27. When the detector 29 detects a patient taking a deep breath, it activates the push rod 25, causing the elastic rod 24 to move to the right. The friction wheel 22 abuts against the larger diameter part of the conical roller 21. Since the speed of the motor 18 is constant, the speed of the friction wheel 22 increases at this time, which in turn increases the speed of the connecting disc 26, drives the inner ring 17 to increase its speed, and then increases the speed of the drive disc 16, ultimately increasing the speed of the windmill 15. This increases the speed of the windmill when the patient takes a deep breath, which not only attracts the patient's attention but also encourages the patient to take a deep breath, thus accelerating the entire anesthesia process.

[0028] A push rod 25 is fixedly connected to the upper inner wall of the mixing tube 5. The output end of the push rod 25 is fixedly connected to the elastic rod 24. Multiple magnetic segments 14 are provided on the inner shaft 11. Each magnetic segment 14 is located directly below each rotating ring 10. The magnetic blocks 12 on each rotating ring 10 are of different sizes. In this invention, the mask 3 is placed over the patient's face during use. The anesthetic drug and oxygen are supplied by the drug delivery tube 1 and the oxygen tube 2. The anesthetic drug enters the mixing tube 5 through the transparent cover 4 and the drug inlet 7 and mixes with the oxygen. Then, it enters the inner tube 6 through the return tube 8 and is finally output to the patient from the mask 3.

[0029] In the process described above, after the medicine enters the transparent cover 4, it will directly blow the fan 15 to rotate, thereby attracting the patient's attention. After being directly mixed with the oxygen tube 5 by the oxygen tube 2, the oxygen tends to move directly to the right, thus colliding with the end of the inner tube 6. Since the end of the inner tube 6 is concave, the oxygen will flow back under the action of the arc surface, thereby colliding with the medicine to produce a more thorough mixture. Then, it enters the inner tube 6 through the return tube 8 and is finally output to the patient from the mask 3.

[0030] In this application, the motor 18 inside the power box 9 drives the active disk 19 to rotate, which in turn drives the inner shaft 11 to rotate. The rotation of the inner shaft 11 causes the magnetic segment 14 on it to rotate, thereby driving the rotating ring 10 to rotate through magnetic force. The rotation of the rotating ring 10 drives the inclined plate 13 to rotate. As the oxygen mixed with the medicine moves to the right, it collides with the inclined plate 13 and flows more chaotically, achieving further mixing.

[0031] In this invention, when the detector 29 detects a patient taking a deep breath, it activates the push rod 25, causing the elastic rod 24 to move to the right. The friction wheel 22 abuts against the larger diameter part of the conical roller 21. Since the speed of the motor 18 is constant, the speed of the friction wheel 22 increases at this time, which in turn increases the speed of the connecting disc 26, drives the inner ring 17 to increase its speed, and then increases the speed of the drive disc 16, ultimately increasing the speed of the windmill 15. This increases the speed of the windmill when the patient takes a deep breath, which not only attracts the patient's attention but also encourages the patient to take a deep breath, thus accelerating the entire anesthesia process.
