Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically, it relates to a portable suction device for use in critical care medicine. Background Technology

[0002] For critically ill patients, post-operative patients, and patients who are too weak to cough up phlegm, hospital medical staff generally need to insert suction catheters every few hours to clear phlegm from the airway. The suction devices used for suctioning are mainly central suction devices and electric suction devices. Central suction devices need to be equipped with a central negative pressure suction interface, but in some auxiliary departments, there is often no central negative pressure interface. In the absence of a central negative pressure interface, medical staff generally use electric suction devices for suctioning.

[0003] Suctioning devices mainly include electric multi-functional negative pressure suctioning devices and simple manual suctioning devices. The operating end needs to be connected to a suction tube or sponge suction tube to be used. Electric suctioning devices are commonly used. They have a power switch and a manual control switch. They use the principle of negative pressure to perform suctioning and oral care. They are simple and easy to learn. They are used for routine suctioning of sputum, tracheotomy and other treatments for wounded and sick personnel. They are suitable for military combat medical care as well as for timely suctioning of sputum in hospitals or homes when there is respiratory mucus or vomit.

[0004] A search revealed that prior art, patent application number 202320518838.4, discloses a portable sputum suction device for respiratory and critical care medicine. After the patient's sputum is suctioned into the sputum collection tank through the suction tube, the controller immediately controls the pump and drive motor to operate. Medication and water are then introduced into the drug mixing tank through the drug inlet. At this time, the drive motor drives the rotating shaft to rotate, which in turn drives multiple stirring blades to thoroughly mix the sputum and medication, thereby accelerating the reaction between the medication and sputum. Finally, the mixture is discharged through the discharge pipe to prevent secondary infection. When the entire device needs to be moved, a push rod is pushed, causing the movable wheels to rotate. Connecting rods connect the support plate and the base plate, which are then fixedly connected to the drug mixing tank, thus moving the device to the designated location and greatly improving work efficiency.

[0005] The above technical solution also has the following drawbacks: When mixing medicine and sputum, the sputum is sticky and will stick to the inner wall of the medicine mixing box. After long-term use, the inside of the medicine mixing box needs to be cleaned manually, which is extremely inconvenient. In addition, the sputum movement between each pair of mixing blades is small during stirring, which means that the sputum between each pair of mixing blades cannot move and displace other sputum during stirring, resulting in poor mixing effect. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A portable sputum suction device for critical care medicine includes a sputum collection box, a suction device at the top of the sputum collection box, a suction head on the suction device, and an outlet of the suction device communicating with the interior of the sputum collection box. A motor is detachably connected to one side of the outer wall of the sputum collection box. The rotating end of the motor is inserted into the interior of the sputum collection box and fixedly connected to a transmission rod. Multiple stirring plates are fixedly connected to the outer wall of the transmission rod. A scraper is fixedly connected to the end of the stirring plates on each horizontal line. The scraper is in close contact with the inner wall of the sputum collection box. The rotation of the motor causes the transmission rod and stirring plates to rotate, and the scraper scrapes and washes the inner wall of the sputum collection box. A drug delivery device is provided on the outer wall of the sputum collection box, and the drug delivery device adds medicine to the interior of the sputum collection box.

[0009] Preferably, each of the scrapers has an arc plate fixedly connected to its outer wall in the same direction. When the scraper rotates, the arc plate rotates, increasing the contact area with the sputum.

[0010] Preferably, each of the scrapers has a vertical plate fixedly connected to its outer wall in the same direction. When the scraper is rotated, the vertical plate rotates to increase the contact area with the sputum.

[0011] Preferably, the drug delivery device includes a drug storage tank, the upper end of which is provided with a drug inlet. The drug storage tank has a built-in delivery pump, and the outlet of the delivery pump is detachably connected to a drug inlet pipe. The drug inlet pipe is rotatably connected to a transmission rod, and the drug passes through the inside of the transmission rod and the stirring plate through the delivery pump and is sprayed out from the outer wall of the stirring plate.

[0012] Preferably, the transmission rod and the stirring plate are hollow inside. The inner wall of the transmission rod is provided with multiple connecting grooves, each connecting groove communicating with the stirring plate. The outer wall of each stirring plate is provided with multiple one-way valves. The end of the transmission rod passes through the sputum storage box and is fixedly connected to a limiting head. One side of the limiting head is rotatably connected to the drug inlet tube, and the other side is rotatably connected to the outer wall of the sputum storage box. The drug inlet tube communicates with the inside of the transmission rod, so that the drug inlet tube continues to feed the drug into the inside when the transmission rod rotates.

[0013] Preferably, the end of the drug inlet tube is fixedly connected to the inner ring of a bearing, and the outer ring of the bearing is fixedly connected to the limiting head.

[0014] Preferably, the bottom of the sputum collection box is detachably connected to a base, and the four corners of the bottom of the base are detachably connected to casters. The outer wall of the sputum collection box is fixedly connected to a handle.

[0015] Beneficial effects

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) In this invention, when in use, the suction device generates suction to draw sputum from the suction head and into the interior of the sputum storage box through the discharge port. The motor is started to drive the transmission rod to rotate. The transmission rod can drive multiple stirring plates to rotate. When rotating, the scraper is in close contact with the inner wall of the sputum storage box and can scrape the sputum on the inner wall when rotating, so that manual cleaning is not required after long-term use.

[0018] (2) In this invention, the arc plate and the vertical plate can push the phlegm inside to move and roll fully when rotating, and can also make the phlegm at the bottom rise up and fall down. This rising and falling method can make the phlegm and medicine mix better.

[0019] (3) In this invention, during stirring, the delivery pump built into the medicine storage tank introduces the medicine into the transmission rod through the medicine inlet pipe, and then into the interior of each stirring plate through the connecting groove. As the pressure rises, each one-way valve is opened, and the medicine is sprayed into the interior of the sputum storage tank. The spraying position is at the center of the sputum storage tank, and thus also at the center of the sputum inside the sputum storage tank, so that the medicine is fully covered by the spray and sputum, further increasing the mixing effect.

[0020] (4) In this invention, the one-way valve can be closed when not in use. After the one-way valve is closed, it can prevent external sputum from entering the transmission rod and the stirring plate. Similarly, the pressure of the medicine can be controlled by adjusting the pressure of the delivery pump. When the pressure of the medicine is increased, it can pass through the sputum inside the sputum storage box, further increasing the mixing effect of the medicine and sputum.

[0021] (5) In this invention, when the inside of the sputum storage box needs to be cleaned after long-term use, clean water is added to the inside of the medicine storage box and enters the inside of the sputum storage box through the delivery pump. The inner wall of the sputum storage box can be cleaned by the rotation of the motor and the scraper. The output pressure of the delivery pump can also be controlled to make the pressure of the clean water sprayed from the one-way valve. The pressurization method can make the water flush the inner wall of the sputum storage box, so that the cleaning effect is better. The medicine storage box and the medicine inlet pipe can also be removed and replaced with a water tank with a built-in delivery pump. The water tank is connected to the limit head through the bearing to clean the inside of the sputum storage box.

[0022] (6) In this invention, the outer ring of the bearing is fixedly connected to the limiting head, and the inner ring of the bearing is fixedly connected to the drug inlet tube. This ensures that the drug inlet is not affected when the bearing rotates, and the internal stirring mechanism can be detected as to whether it is operating normally by observing the rotation of the limiting head.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0033] like Figure 1-5The diagram shown is a schematic representation of a portable sputum suction device for critical care medicine according to a preferred embodiment of the present invention. This portable sputum suction device for critical care medicine includes a sputum collection box 1. A suction device 2 is mounted on the upper end of the sputum collection box 1, and a suction head 3 is installed on the suction device 2. The discharge end of the suction device 2 communicates with the interior of the sputum collection box 1, allowing sputum to be suctioned by the suction device 2 and then transported and collected into the sputum collection box 1. The suction device 2 generates suction to draw sputum from the suction head 3 and discharge it into the sputum collection box 1 below. An electric... The rotating end of the motor 8 is inserted into the sputum storage box 1 and is fixedly connected to the transmission rod 12. Multiple stirring plates 13 are fixedly connected to the outer wall of the transmission rod 12. When the motor 8 rotates, it drives the transmission rod 12 to rotate, causing the multiple stirring plates 13 to rotate and stir the sputum inside. Each horizontal stirring plate 13 has a scraper 15 fixedly connected to its end. Each scraper 15 is in contact with the inner wall of the sputum storage box, so that when the motor 8 drives the transmission rod 12 to rotate, it can scrape off the sputum adhering to the inner wall. The multiple scrapers 15 can increase the stirring effect of sputum inside the sputum storage box 1.

[0034] Each scraper 15 has an arc plate 16 fixedly connected to the outer wall on the same side, and a vertical plate 17 fixedly connected to the inner wall on the same side of each arc plate 16. The arc plate 16 and the vertical plate 17 can push the sputum inside to move fully when rotating, so that each part of the sputum can move and roll to increase the mixing effect. This allows the sputum inside the sputum storage box 1 to move fully and mix with the medicine, and can also push the sputum to move in a circular motion and rise upward inside the sputum storage box 1, thereby further increasing the mixing effect of the sputum. The outer wall of the sputum storage box 1 is equipped with a drug delivery device, which delivers medicine into the sputum storage box 1. The arc plate 16 and the vertical plate 17 work together to make the sputum rise and improve the mixing effect with the medicine, thus avoiding secondary infection.

[0035] The drug delivery device includes a drug storage box 5, which is detachably connected to the outer wall of the sputum storage box 1. The inside of the drug storage box 5 is used to store medicines. The outer wall of the drug storage box 5 is provided with a drug inlet 6, through which medicines are added to the inside of the drug storage box 5. The drug storage box 5 has a built-in delivery pump, and the outlet end of the delivery pump is detachably connected to a drug inlet pipe 20. The delivery pump delivers the medicines inside the drug storage box 5 into the sputum storage box 1 and mixes them with the sputum inside with agitation. The end of the drug inlet pipe 20 is fixedly connected to the inner ring of a bearing 19. The outer wall of the outer ring of the bearing 19 is fixedly connected to a limiting head 18. The limiting head 18 is fixedly connected to the end of a transmission rod 12. When the transmission rod 12 rotates, the limiting head 18 drives the outer ring of the bearing 19 to rotate, while the drug inlet pipe 20 and the inner ring of the bearing 19 do not rotate. Therefore, rotation does not affect drug delivery. The delivery pump delivers the medicines inside the drug storage box 5 into the sputum storage box 1, and the motor drives the transmission rod 12 and the stirring plate 13 to rotate, facilitating the mixing of medicines with sputum.

[0036] The transmission rod 12 is hollow and connected to the drug inlet pipe 20. Multiple through-hole connecting grooves 9 are provided on the inner wall of the transmission rod 12. The stirring plate 13 is also hollow, and each connecting groove 9 connects to a hollow part inside the stirring plate 13, allowing the medicine inside the storage tank 5 to be transported by the delivery pump through the drug inlet pipe 20 into the transmission rod 12, and then through the connecting grooves 9 into the stirring plate 13. Multiple one-way valves 14 are provided on the outer wall of each stirring plate 13. The delivery pump draws the medicine into the transmission rod 12 and then into the stirring plate 13. When the medication is delivered, the pressure of the parameters opens each one-way valve 14, and the medication enters the sputum storage tank 1 through the one-way valve 14. When no medication is being delivered, the one-way valve 14 automatically closes, thereby preventing sputum from flowing into the transmission rod 12 and the stirring plate 13. In conjunction with the rotation of the motor 8, the transmission rod 12 and the stirring plate 13 can deliver medication into the sputum storage tank 1 while rotating, and the medication is dispensed from the center of the sputum storage tank, so that when the medication comes into contact with the sputum, it is at the center of the sputum inside the sputum storage tank 1. The medication and sputum are then thoroughly mixed by stirring, resulting in a better mixing effect.

[0037] The bottom of the sputum collection box 1 is detachably connected to a base 10, and the four corners of the bottom of the base 10 are detachably connected to casters 11. The outer wall of the sputum collection box 1 is fixedly connected to a handle 4. The handle 4 can be used in conjunction with the casters 11 to move the equipment, and the equipment can be moved to a designated location according to actual needs.

[0038] The end of the transmission rod 12 passes through the sputum storage box 1, and the limiting head 18 is rotatably connected to the outer wall of the sputum storage box 1. The limiting head 18 and the transmission rod 12 communicate internally. The rotatable connection between the limiting head 18 and the sputum storage box can increase the sealing performance, prevent sputum from leaking out between the transmission rod 12 and the sputum storage box, and make it easier to connect to the bearing 19. Furthermore, the rotation of the limiting head 18 makes it easier to observe the stirring speed and whether the internal transmission rod 12 is stirring, so that the internal stirring mechanism can be observed from the outside to see if it is working properly.

[0039] During use, the suction device 2 generates suction to draw sputum from the suction head 3 and into the sputum storage box 1 through the discharge port. The motor 8 is started, driving the transmission rod 12 to rotate. The transmission rod 12 then drives multiple stirring plates 13 to rotate. During rotation, the scraper 15 adheres closely to the inner wall of the sputum storage box 1, scraping off the sputum. This eliminates the need for manual cleaning after prolonged use. When cleaning the inside of the sputum storage box 1 is required after extended use, clean water is added to the medicine storage box 5 and pumped into the sputum storage box 1. The rotation of the motor 8, in conjunction with the scraper 15, removes the sputum. 5 can clean the inner wall of the sputum collection box 1. It can also control the output pressure of the delivery pump to increase the pressure of the water sprayed from the one-way valve 14. The pressurized method can make the water flush the inner wall of the sputum collection box 1, resulting in a better cleaning effect. It can also remove the medicine storage box 5 and the medicine inlet pipe 20 and replace them with a water tank with a built-in delivery pump. The water tank is connected to the limit head 18 through the bearing 9 to clean the inside of the sputum collection box 1. The arc plate 16 and the vertical plate 17 can push the sputum inside to move and roll fully when rotating. It can also make the sputum at the bottom rise up and fall down. This lifting and falling method The mixing effect of sputum and medicine is improved. During stirring, the delivery pump built into the medicine storage tank 5 sends the medicine into the transmission rod 12 through the medicine inlet pipe 20, and then into each stirring plate 13 through the connecting groove 9. As the pressure rises, each one-way valve 14 is opened, and the medicine is sprayed into the sputum storage tank 1. The spray position is at the center of the sputum storage tank 1, which is also the center of the sputum inside the sputum storage tank 1, so that the medicine is fully covered by the spray and sputum, which further enhances the mixing effect. In addition, the one-way valve 14 can be used when not in use. When the one-way valve 14 is closed, it can prevent external sputum from entering the transmission rod 12 and the stirring plate 13. It can also control the pressure of the medicine spray by adjusting the pressure of the delivery pump. When the pressure of the medicine sprays out increases, it can pass through the sputum inside the sputum storage box 1, further increasing the mixing effect of the medicine and sputum. The outer ring of the bearing 19 is fixedly connected to the limit head 18, and the inner ring of the bearing 19 is fixedly connected to the medicine inlet pipe 20. It can ensure that the medicine is not affected when rotating, and by observing the rotation of the limit head 18, it can be detected whether the internal stirring mechanism is operating normally.
