Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular to a portable medical disinfector. Background Art

[0002] Currently, in the medical industry, when medical staff perform disinfection treatments on surgical skin wounds, anesthesia punctures, surgical incisions, etc. of patients, the following treatment methods are generally adopted: Pour the disinfectant into a disinfection cup or bowl, then put cotton balls or gauze pieces to absorb the disinfectant, use a disinfection ring forceps or tweezers to take out the cotton balls or gauze pieces full of disinfectant, and clamp them to the disinfection site for disinfection treatment to achieve the purpose of disinfection. From the above entire disinfection process, it can be seen that the disinfection process is still relatively cumbersome. To reduce the complexity and safety of the work of medical staff and lower the management and material procurement costs, therefore, it is necessary for us to develop a portable and easy-to-use medical disinfector.

[0003] Existing disinfectors are inconvenient to use and carry. For example, in the patent with the publication number CN213100389U, a disinfection cotton cylinder type container is disclosed. The disinfection cotton cylinder type container includes a disinfection cylinder, a foam cotton stick body, etc. However, when the foam cotton stick body is not connected to the disinfection cylinder, the push rod can also be pushed to make the disinfectant flow out of the disinfection cylinder. The risk of misoperation by medical staff is not fully considered in the operation process, and the safety is not very high. Therefore, for the problem that this disinfector often needs to use cotton balls for disinfection, we introduce a spray type disinfector device for replacement. At the same time, while being convenient to carry, it is convenient to adapt different disinfectants. At the same time, the capacity of existing disinfectors is limited, so it is necessary for us to develop a portable medical disinfector to solve the above problems. Summary of the Utility Model

[0031] The following will further elaborate on the specific embodiments of the present utility model in conjunction with the attached Figures 1-13 This utility model's specific embodiments are further described in detail.

[0032] Embodiment 1. A portable medical disinfector includes a cylinder body 1. The diameter of the cylinder body 1 is equivalent to that of a mineral water bottle. A vertical threaded through hole 2 is provided on the sealing cover integrally connected to the cylinder body 1. The diameter of the threaded through hole 2 is smaller than that of the cylinder body 1. The threaded through hole 2 can be used for liquid inlet treatment. An air guiding structure 3 extending to the bottom of the cylinder body 1 is movably connected in the threaded through hole 2. The air guiding structure 3 is screwed with the internal thread in the threaded through hole 2 by setting an external thread to achieve the movable connection of the air guiding structure 3. An annular closed cavity 4 is formed in the sealing cover. The upper and lower parts in the closed cavity 4 are sealed. A water suction pipe 5 with two ends respectively placed in the closed cavity 4 and the bottom of the cylinder body 1 is vertically connected to the sealing cover. A retaining net 19 is arranged at the lower end of the water suction pipe 5. The retaining net 19 is used to block foreign objects at the lower end of the water suction pipe 5. One end of the water suction pipe 5 placed in the closed cavity 4 is connected to an annular water outlet pipe 6. One end of the water outlet pipe 6 is communicated with the water suction pipe 5 to suck the water in the cylinder body 1 into the water suction pipe 5. The water outlet pipe 6 extends from the closed cavity 4 to the outside of the cylinder body 1, and an atomizing nozzle 7 is installed at the end. The water outlet pipe 6 is arranged in an annular shape and flows out from the outlet of the water outlet pipe 6;

[0033] One side of the cylinder body 1 is arranged in a notch shape, and a handle 8 is arranged in the notch shape. The user can take it by inserting the hand into the handle 8 at the notch, which conforms to the ergonomic design and is convenient for carrying. A pressing switch structure 9 for conducting the water outlet pipe 6 is arranged on the water outlet pipe 6. The pressing switch structure 9 and the handle 8 are arranged on the same side. The purpose of designing them on the same side is to facilitate the user to operate with one hand. The pressing switch structure 9 is used to conduct the water outlet pipe 6, and the handle 8 is used to take the cylinder body 1, which is convenient for the user to operate with one hand. The pressing switch structure 9 includes a notch 20 vertically opened on the water outlet pipe 6. Limiting grooves 21 are opened on both sides of the notch 20. A sealing plug 22 is vertically slidably connected in the notch 20, so that the sealing plug can only move along the vertical direction. Rubber is arranged between the limiting groove 21 and the sealing plug 22 to ensure airtightness. A water passing hole 23 matching the water outlet pipe 6 is opened on the sealing plug 22 along the direction of the water outlet pipe 6. A return spring 24 is connected between the lower end of the sealing plug 22 and the bottom of the closed cavity 4. When the return spring 24 is in a compressed state, the water passing hole 23 is communicated with the water outlet pipe 6. A pressing handle 25 is arranged on the sealing plug 22. The pressing handle 25 is retracted into the cylinder body 1 and is on the same side as the handle 8. In the case where the spring is in a natural state, the water passing hole 23 is not communicated with the water outlet pipe 6. Once the sealing plug 22 is pressed through the pressing handle 25, the return spring 24 will contract, so that the water passing hole 23 on the sealing plug 22 is communicated with the water outlet pipe 6 to achieve the effect of connection;

[0034] When this embodiment is in use, the air intake structure 3 is removed by screwing, and the disinfectant is injected into the cylinder body 1 through the threaded through hole 2. After injection, a certain space should be reserved for the height of the disinfectant, and then the air intake structure 3 is screwed on, so as to facilitate carrying. When in need of use, the user holds the handle 8. When disinfection is required, the air is introduced to the bottom of the liquid through the air intake structure 3, and small bubbles appear at the bottom of the liquid. The small bubbles carry air and move upward from the bottom of the liquid. More and more air accumulates in the reserved space in the cylinder body 1. Since the pressing switch structure 9 in the water outlet pipe 6 is in a closed state, the liquid cannot flow out of the water outlet pipe 6 temporarily. As more and more air accumulates in the reserved space, a pressure area will be formed inside, making the pressure in the reserved space greater than the external pressure. When the air intake structure 3 stops introducing air and disinfection treatment is required, hold the cylinder body 1 and aim the atomizing nozzle 7 at the item or wound to be disinfected. As long as the user presses the pressing switch structure 9 to make the water outlet pipe 6 conductive, the liquid discharging work can be realized. The liquid is atomized after passing through the atomizing nozzle 7, and then the item to be disinfected is disinfected. The spraying treatment can be continuously carried out until the air pressure in the internal space is consistent with the external air pressure. After disinfection, if there is still pressure remaining in the cylinder, the device can be inverted and the pressing switch device can be pressed to make the water outlet pipe 6 conductive for pressure relief treatment. This embodiment is convenient to carry, the disinfectant spraying is continuous, and the disinfection is efficient. The whole process uses air pressure for disinfectant spraying work, with strong practicability and is suitable for popularization.

[0035] Embodiment 2. On the basis of Embodiment 1, the air intake structure 3 includes an intake cylinder 10 threadedly fitted in the threaded through hole 2. The intake cylinder 10 is provided with an external thread on the outside, which facilitates screwing the intake cylinder 10 into the threaded through hole 2 on the cylinder body 1. A plug 11 is connected to the air outlet hole 13 at the lower end of the intake cylinder 10. A glass ball 12 is movably connected in the plug 11. When the glass ball 12 moves downward, the air outlet hole 13 remains unblocked. When it moves upward to the limit position, the air outlet hole 13 is blocked. Under the action of air pressure and air flow, when the glass ball 12 moves downward, it cooperates with the inside of the cylinder body 1, so that no matter how the glass ball 12 moves, the passage cannot be completely blocked. On the other side, during the process of moving upward to the limit position and matching with the circular ventilation hole, under the action of air pressure, the glass ball 12 is reliably pressed on the ventilation hole to completely block it. Thus, when moving upward, the air outlet hole 13 is blocked, and when moving downward, the air outlet hole 13 is opened. A piston rod 14 is slidably fitted along the axis in the intake cylinder 10. There is a gap between the piston rod 14 and the intake cylinder 10. One end of the piston rod 14 placed in the intake cylinder 10 is sequentially connected with a rubber cup 15 and a piston 16. The rubber cup 15 is in clearance fit with the wall of the intake cylinder 10. The radius of the piston 16 is smaller than that of the rubber cup 15. A rubber ring 17 that can slide axially with damping is coaxially sleeved between the rubber cup 15 and the piston 16. The rubber ring 17 is in clearance fit with the wall of the intake cylinder 10. When the piston rod 14 is pushed outward, the rubber ring 17 fits together with the piston 16 under the action of friction. At this time, the glass ball 12 blocks the lower air outlet hole 13 under the action of air pressure. Since the rubber cup 15 is in clearance fit with the cylinder wall, the outside air flows through the upper part of the intake cylinder 10, through the rubber cup 15 and into the lower chamber. Once the piston rod 14 is pushed downward first, at this time, the rubber ring 17 moves downward under the action of friction. At this time, the rubber ring 17 pushes the rubber cup 15 to tightly fit with the cylinder wall. At the same time, under the action of air pressure, the glass ball 12 moves downward to open the air outlet hole 13, so that the gas can smoothly enter the cylinder body 1. As the pushing progresses, the whole process is stable, reliable and safe, and has strong practicability. When inflating, the piston 16 is pushed upward, the glass ball 12 moves upward to block the air outlet hole 13, and the gas passes through the rubber cup 15 from above to open it and enter the lower chamber, thus completing the inflation work. This process is repeated to introduce air into the cylinder body 1.

[0036] Embodiment 3. On the basis of Embodiment 1, a water inlet pipe 26 is provided in the direction on the other side of the cylinder body 1 away from the handle 8. Internal threads are provided inside the water inlet pipe 26. It also includes a threaded cylinder 27 with external threads. The threaded cylinder 27 is matched with a knob 28 for the internal threads in the water inlet pipe 26. During use, when there is not much remaining liquid, disinfectant can be placed at the water inlet pipe 26 without opening the air intake structure. A medicine loading cylinder 29 is coaxially connected in the threaded cylinder 27. Scales 30 are provided on the outer side wall of the medicine loading cylinder 29. A driving knob 3128 is provided outside the threaded cylinder 27. When a special solution needs to be prepared, the prepared medicine can be placed in the medicine loading cylinder 29. There are scales 30 on it, which can show the amount of liquid, so as to complete the preparation work of the special disinfection liquid, and it is convenient and simple to use;

[0037] A hook 40 is rotatably connected outside the threaded cylinder 27. A torsion spring is provided between the hook 40 and the threaded cylinder 27. A retaining hook 41 is provided between the hook 40 and the cylinder body 1. The retaining hook 41 is in inclined surface fit with the hook 40, which is convenient for the user to hang the cylinder body 1 on the waist. By pressing the hook 40 and then hanging it on the waist and releasing the hook 40.

[0038] Embodiment 4. On the basis of Embodiment 1, a plugging plate 32 is vertically slidably connected to the lower end inside the cylinder body 1. An annular fixing plate body is arranged at the lower end inside the cylinder body 1. The plugging plate 32 is vertically slidably connected between the fixing plate body and the bottom of the cylinder. The plugging plate 32 is annularly arranged. A telescopic spring 33 is connected between the plugging plate 32 and the cylinder body 1. The telescopic spring 33 compresses to plug between the plugging plate 32 and the cylinder body 1. When the telescopic spring 33 is in the natural state, it presses the plugging plate 32 against the lower end of the cylinder body 1. Multiple groups of first through holes 34 are opened at the lower end of the cylinder body 1. Second through holes 35 are opened on the plugging plate 32 and are arranged in a staggered manner with the first through holes 34. The positions of the first through holes 34 and the second through holes 35 are staggered. During the cooperation between the plugging plate 32 and the lower end of the cylinder body 1, the first through holes 34 and the second through holes 35 are not communicated, so as to achieve the plugging effect. However, after the plugging plate 32 is separated from the lower end of the cylinder body 1, due to the staggering of the first through holes 34 and the second through holes 35, the liquid will flow out of the cylinder body 1 to the outside of the cylinder body 1. It further includes a liquid storage cylinder 36. Multiple circular cylinders 37 matching the first through holes 34 are connected to the upper end of the liquid storage cylinder 36. The purpose of the circular cylinders 37 is to push open the plugging plate 32 through the first through holes 34. Multiple groups of third through holes 38 are opened at the upper end of the liquid storage cylinder 36. After the circular cylinders 37 push open the plugging plate 32, the first through holes 34, the third through holes 38 and the second through holes 35 are communicated, so that the liquid enters the lower liquid storage cylinder 36 to complete the extended storage work of the liquid. A locking knob 3928 is rotatably connected to the outside of the liquid storage cylinder 36. The locking knob 3928 is in threaded cooperation with the outer side wall of the cylinder body 1. The liquid storage cylinder 36 is screwed onto the outer side wall of the cylinder body 1 by tightening and screwing. The diameter of the lower end of the liquid storage cylinder 36 is larger than the diameter of the cylinder body 1. When this embodiment is in use, the liquid storage cylinder 36 is screwed onto the outer side wall of the cylinder body 1 by tightening the knob 28. The circular cylinders 37 push open the plugging plate 32 from the bottom of the cylinder body 1 after inserting into the first through holes 34. The first through holes 34 and the third through holes 38 are opened, and the liquid enters the liquid storage cylinder 36 from the through holes to achieve the effect of liquid expansion. If the expansion is not needed, the liquid storage cylinder 36 is screwed off, and the plugging plate 32 resumes plugging.

[0039] When the utility model is in use, the air intake structure 3 is removed by screwing it off, and the disinfectant is injected into the cylinder body 1 through the threaded through hole 2. After injection, a certain space should be reserved for the height of the disinfectant, and then the air intake structure 3 is screwed on, so as to facilitate carrying. When in need of use, the user holds the handle 8. When disinfection is required, the gas is introduced to the bottom of the liquid through the air intake structure 3. Specifically, when the piston rod 14 is pushed outwards, the rubber ring 17 fits with the piston 16 under the action of friction. At this time, the glass ball 12 blocks the lower air outlet hole 13 under the action of air pressure. Since the rubber cup 15 has a clearance fit with the cylinder wall, the outside gas flows through the upper part of the air intake cylinder 10 and enters the lower chamber through the rubber cup 15. Once the piston rod 14 is pushed down first, at this time, the rubber ring 17 moves downwards under the action of friction. At this time, the rubber ring 17 pushes the rubber cup 15 to make it tightly fit with the cylinder wall. At the same time, under the action of air pressure, the glass ball 12 moves downwards to open the air outlet hole 13, so that the gas can smoothly enter the cylinder body 1. As the pushing progresses, the whole process is stable, reliable and safe, with strong practicability. When inflating, the piston 16 is pushed upwards, the glass ball 12 moves upwards to block the air outlet hole 13, and the gas passes through the rubber cup 15 from above to open it and enter the lower chamber, thus completing the inflation work. This process is repeated to introduce air into the cylinder body 1, and small bubbles appear at the bottom of the liquid. The small bubbles carry air and move upwards from the bottom of the liquid. More and more air accumulates in the reserved space in the cylinder body 1. Since the pressure switch structure 9 in the water outlet pipe 6 is in a closed state, the liquid cannot flow out of the water outlet pipe 6 temporarily. As more and more air accumulates in the reserved space, a pressure area will be formed inside it, making the pressure in the reserved space greater than the external pressure. When the air intake structure 3 stops introducing air and disinfection treatment is required, hold the cylinder body 1 and aim the atomizing nozzle 7 at the item or wound to be disinfected. As long as the user presses the pressure switch structure 9 to make the water outlet pipe 6 conduct, the liquid discharging work can be realized. The liquid is atomized after passing through the atomizing nozzle 7, and then the item to be disinfected is disinfected. Continuous spraying treatment can be carried out until the air pressure in the internal space is consistent with the external air pressure. After disinfection, if there is still pressure remaining in the cylinder, the device can be inverted and the pressure switch device can be pressed to make the water outlet pipe 6 conduct for pressure relief treatment. This embodiment is convenient to carry, the disinfectant spraying is continuous, and the disinfection is efficient. The whole process uses air pressure for disinfectant spraying work, with strong practicability and is suitable for popularization.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
