Description

Technical Field

[0001] The invention relates to the technical field of medical waste sample treatment, in particular to a waste sample treatment device for clinical testing. Background Art

[0002] Waste samples for clinical testing usually refer to waste generated during medical testing, including but not limited to used reagents, blood samples, tissue samples, etc. These waste samples may contain infectious substances and need to be crushed and disinfected to avoid harm to the environment and medical staff. Common waste sample processing devices are equipped with crushing rods and crushing blades, which are driven by motors to crush waste samples. At the same time, they are disinfected with fixed disinfection lamps and moving disinfection lamps to completely eliminate the germs in the waste samples and prevent the spread of germs.

[0003] The existing waste sample processing device has a poor pulverizing effect on waste samples. To solve this problem, patent CN113714249B discloses a waste sample processing device for clinical medical testing. Through the pulverizing mechanism and cutting mechanism, the medical waste samples can be pulverized twice, and with the cooperation of the disinfection component, the pulverized waste samples can be disinfected in all directions. The device can improve the pulverizing effect to a certain extent, but the existing waste sample processing device still has the following shortcomings:

[0004] 1. Existing waste sample treatment devices generally adopt fixed treatment methods, but waste samples include multiple types, such as (1) blood collection tubes and blood collection bags used for blood samples, which are generally made of high-toughness plastic to prevent sample leakage; (2) urine cups used for urine samples and feces samples, which are generally made of low-toughness plastic and have a certain degree of brittleness; (3) reagent bottles, droppers, glass bottles, syringes, cotton swabs, etc. used for chemical reagent waste samples. Such containers usually contain corrosive, toxic or other potential hazards and require special safety treatment methods. If they are handled uniformly, there are certain safety hazards. In addition, even if high-toughness containers such as blood collection bags are crushed multiple times, it is still difficult to achieve the ideal crushing effect.

[0005] 2. Existing waste sample processing devices are unable to identify and classify waste samples, and waste sample classification and separate processing by category have not yet been achieved.

[0006] 3. Waste sample treatment generally adopts the method of stirring and crushing. After the crushing operation is completed, the waste sample fragments are easy to adhere to the bottom of the device or the crushing blade, resulting in residual waste sample fragments.

[0007] In view of this, how to provide a waste sample treatment device for clinical testing that can partially or completely solve the above-mentioned technical problems is an issue that technical personnel in this field urgently need to solve. Summary of the invention

[0043] 4. Before the waste samples are crushed, they are stored in various temporary storage boxes. When they reach a certain volume, the photoelectric sensor is triggered. At this time, they can be sent to the crushing device or cooling device for unified treatment, reducing the cost of use.

[0044] 5. When using chemical treatment methods to reduce the toughness of high-toughness waste samples, spraying chemical reagent cleaning fluid on the waste samples during the disinfection process can avoid chemical reagent residues and cause pollution to the surrounding environment.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] Example 1

[0057] like Figure 1 As shown, an embodiment of the present invention provides a waste sample processing device for clinical testing. The overall size of the waste sample processing box 1 is close to that of a street trash can, which is about 1.3 meters high. The top of the waste sample processing box 1 is provided with a delivery port 101, which is generally funnel-shaped and connected to a connecting pipe at its bottom. A first valve 28 is provided on the connecting pipe; a code scanning camera 2 is arranged at the top of the waste sample processing box 1 and is close to the delivery port 101; a classification pushing mechanism is arranged in the waste sample processing box 1 and corresponds to the position of the delivery port 101. The code scanning camera 2 can capture and identify the information of the waste sample and send an electrical signal to the control center. The control center identifies the category of the waste sample based on the electrical signal sent by the code scanning camera 2, and controls the classification pushing mechanism to push the waste sample to the corresponding waste sample processing device according to the category of the waste sample.

[0058] In this embodiment, waste samples are divided into high-toughness waste samples, low-toughness waste samples and chemical waste samples. A two-dimensional code identification layer is sprayed on the surface of the waste sample according to the category to which the waste sample belongs. A barcode identification layer of appropriate size can also be set according to the size of the waste sample, etc. The identification layer is sprayed before the sample is used. The actual function of the sample needs to be considered and sprayed in a position that does not affect its normal use. The control center stores the waste sample category data; the code scanning camera 2 can shoot and identify the two-dimensional code identification layer and convert it into an electrical signal and send it to the control center. The control center confirms the category of the waste sample based on the electrical signal sent by the code scanning camera 2 and the waste sample category data.

[0059] In this embodiment, the classification push mechanism includes: a conveyor belt 3, the upper surface of the conveyor belt 3 has a delivery area 301, and the delivery area 301 corresponds to the delivery port 101; a push component, the push component is arranged on one side of the conveyor belt 3, and the feed end of the waste sample processing device is arranged on the other side of the conveyor belt 3 and close to the conveyor belt 3; the push component and the conveyor belt 3 are both electrically connected to the control center. When the control center confirms the category of the waste sample, the control center controls the conveyor belt 3 to move the waste sample to the corresponding push component, and pushes the waste sample to the feed end of the waste sample processing device through the push component. The push component includes: a push motor 4, the push motor 4 is arranged on one side of the conveyor belt 3; a push plate 5, the output end of the push motor 4 faces the feed end of the waste sample processing device, the push plate 5 is fixedly connected to the output end of the push motor 4, the push plate 5 is close to the upper surface of the conveyor belt 3, and there is a gap between the push plate 5 and the upper surface of the conveyor belt 3.

[0060] A gravity sensor is arranged at the delivery area 301 of the conveyor belt 3. When the gravity sensor detects a change in gravity, it sends a signal to the control center, and the control center controls the first valve 28 to be closed. After the pushing component pushes the waste sample to the feed end of the waste sample processing device, the gravity sensor sends a signal to the control center again, and the control center controls the first valve 28 to be opened, so as to avoid the situation where the previous waste sample has not yet fallen into the corresponding waste sample processing device, and the next waste sample has already fallen onto the conveyor belt 3, causing a system error.

[0061] Under normal circumstances, the first valve 28 can also be set to be closed. When the barcode scanning camera 2 sends an electrical signal to the control center, the control center opens the first valve 28 to prevent dust from entering when not in use.

[0062] In this embodiment, the waste sample processing device includes a high-toughness waste sample processing device, a low-toughness waste sample processing device and a chemical waste sample processing device, which respectively process high-toughness waste samples, low-toughness waste samples and chemical waste samples.

[0063] like Figure 1 and Figure 2As shown, the high-toughness waste sample processing device includes: a first feed pipe 6, the first feed pipe 6 is arranged near the conveyor belt 3, the upper end of the first feed pipe 6 is a feed port, which is generally funnel-shaped, and the pushing component can push the high-toughness waste sample into the first feed pipe 6; a first temporary storage box 7, the first temporary storage box 7 is connected to the lower pipe port of the first feed pipe 6, and a first photoelectric sensor 10 is arranged in the first temporary storage box 7. The first photoelectric sensor 10 is arranged near the top of the first temporary storage box 7. When the accumulated height of the high-toughness waste sample reaches the first photoelectric sensor 10, the high-toughness waste sample blocks the light emitted by the first photoelectric sensor 10, and the first photoelectric sensor 10 sends a signal to the control center; The toughness reducing mechanism 8 is connected with the first temporary storage box 7, and a second valve 29 is arranged at the connection point. When the first photoelectric sensor 10 sends a signal to the control center, the control center controls the second valve 29 to open, and the first temporary storage box 7 discharges the high-toughness waste sample into the toughness reducing mechanism 8. The toughness reducing mechanism 8 is a freezer, and the lowest freezing temperature can reach -70 degrees Celsius. The freezer reduces the toughness of the high-toughness waste sample by cooling. The first crushing mechanism 9 is connected with the toughness reducing mechanism 8, and a third valve 30 is arranged at the connection point. When the freezing is completed, the control center controls the third valve 30 to open, and the high-toughness waste sample in the freezer is discharged into the first crushing mechanism 9 for crushing.

[0064] The toughness of plastic bags is greatly affected by temperature, especially when the temperature drops below the glass transition temperature (Tg) of the plastic, the plastic will change from a highly elastic state to a glassy state. When the plastic bag is frozen, the movement of its molecular chains is restricted, causing the material to become hard and brittle, and the toughness of the plastic will decrease. Taking blood collection bags as an example, blood collection bags are usually made of high-toughness plastic materials. These materials need to meet the requirements of safety, sterility, and anti-microbial contamination, and must be compatible with blood. Existing blood collection bags are generally made of the following materials:

[0065] Polyvinyl chloride (PVC): This is a material commonly used to make blood collection bags, but it may contain plasticizers such as di(2-ethylhexyl) phthalate (DEHP).

[0066] Polypropylene (PP): Polypropylene is also a suitable material for making blood collection bags due to its chemical corrosion resistance and high temperature resistance.

[0067] For different materials, an absolute freezing temperature should be set according to the temperature required for different materials to be frozen and toughened. After experiments, the freezing temperatures for the toughening of the above two materials are as follows:

[0068] Polypropylene (PP): Polypropylene is a heat-resistant and corrosion-resistant material, but its low-temperature impact resistance is poor. The isotactic structure content of industrially produced polypropylene resin is about 95%, and it has a high melting point (about 167°C). Polypropylene copolymers have lower heat deformation temperatures and stronger toughness. Considering its poor low-temperature impact resistance, it is recommended that the freezing temperature be lower than -20°C in order to achieve a toughening effect.

[0069] Polyvinyl chloride (PVC): PVC has poor cold resistance, and the lower limit of the use temperature of hard PVC is generally -15°C. In the freezing toughening treatment, the recommended freezing temperature of PVC needs to be lower than its lower limit of use temperature, that is, lower than -15°C.

[0070] Therefore, the toughness reduction effect can be achieved by setting the freezing temperature below -20°C. When high-toughness waste samples are mixed with other high-toughness waste samples, the lowest temperature required for toughness reduction of various materials should be comprehensively considered to set the optimal freezing toughness reduction temperature.

[0071] In this embodiment, the low-toughness waste sample processing device includes: a second feed pipe 11, the second feed pipe 11 is arranged near the conveyor belt 3, the upper end of the second feed pipe 11 is a feed port, which is generally funnel-shaped, and the pushing component can push the low-toughness waste sample into the second feed pipe 11; a second temporary storage box 12, the second temporary storage box 12 is connected to the lower pipe port of the second feed pipe 11, and a second photoelectric sensor 13 is arranged in the second temporary storage box 12. The second photoelectric sensor 13 is arranged near the top of the second temporary storage box 12. When the accumulated height of the low-toughness waste sample reaches the second photoelectric sensor 13, the low-toughness waste sample blocks the light emitted by the second photoelectric sensor 13, and the second photoelectric sensor 13 sends a signal to the control center; a second crushing mechanism 14, the second crushing mechanism 14 is connected to the second temporary storage box 12, and a fourth valve 31 is arranged at the connection point. When the second photoelectric sensor 13 sends a signal to the control center, the control center controls the fourth valve 31 to open, and the second temporary storage box 12 discharges the low-toughness waste sample into the second crushing mechanism 14 for crushing processing.

[0072] The low-toughness waste sample processing device is the same as the traditional crushing type waste sample processing device, but because the waste samples are classified, the low-toughness waste sample processing device is only used to crush low-toughness waste samples. Its crushing effect is much better than that of the traditional crushing type waste sample processing device, and there is basically no problem of waste samples being unable to be crushed.

[0073] In this embodiment, a disinfection box 15 is also included. The high-toughness waste sample processing device, the disinfection box 15, the low-toughness waste sample processing device and the chemical waste sample processing device are arranged in order from left to right. A pad 17 is provided at the bottom of the first crushing mechanism 9 and the second crushing mechanism 14 to level the height difference between the two, so that the upper ends of the first feed pipe 6 and the second feed pipe 11 are flush. The disinfection box 15 is connected to the first crushing mechanism 9 and the second crushing mechanism 14 respectively. A filter screen 18 is provided near the bottom of the disinfection box 15. The setting position of the filter screen 18 is lower than the connection between the disinfection box 15 and the first crushing mechanism 9 and the second crushing mechanism 14. A liquid collecting tank 19 is provided below the filter screen 18. A spraying mechanism 16 is provided on the top of the disinfection box 15. The spraying mechanism 16 can spray disinfectant in the direction of the filter screen 18. The liquid collecting tank 19 can collect the used disinfectant and discharge it through the drain pipe 20. The waste sample treatment box 1 is provided with a first sampling door 33 at a certain distance above the filter screen 18, which can recycle the waste sample fragments after crushing and disinfection. The spray mechanism 16 is connected to the disinfectant storage tank 21, which is connected to the spray mechanism 16 through a liquid pipeline. A fifth valve 32 is provided on the liquid pipeline, which is controlled by the control center to open and close and thus control the spraying amount of the disinfectant. The waste sample treatment box 1 is provided with a second sampling door 34 at the position corresponding to the disinfectant storage tank 21, which is convenient for replenishing and replacing the disinfectant.

[0074] like Figure 1 and Figure 5 As shown, in this embodiment, it also includes: a vibrating discharging mechanism, which is arranged at the bottom of the first crushing mechanism 9 and the second crushing mechanism 14, and the vibrating discharging mechanism includes: a supporting spring 22, which has a plurality of supporting springs 22 and is vertically arranged at the bottom of the first crushing mechanism 9 and the second crushing mechanism 14; an inclined plate 23, the inclined plate 23 is fixedly arranged on the plurality of supporting springs 22, and the lower end of the inclined plate 23 faces the disinfection box 15, and the first crushing mechanism 9 and the second crushing mechanism 14 are provided with a discharging port corresponding to the lower end of the inclined plate 23, and the discharging port is provided with a discharging valve; a vibrator 24, the vibrator 24 is fixedly arranged on the lower surface of the inclined plate 23, and the vibrator 24 is spaced apart from the supporting spring 22.

[0075] like Figure 4As shown, the chemical waste sample processing device includes: a third feeding pipe 25, which is arranged near the conveyor belt 3, and the upper end of the third feeding pipe 25 is a feeding port, which is generally funnel-shaped, and the pushing component can push the chemical waste sample into the third feeding pipe 25; a third temporary storage box 26, which is connected to the lower pipe port of the third feeding pipe 25, and a third photoelectric sensor 27 is arranged in the third temporary storage box 26, and the third photoelectric sensor 27 is arranged near the top of the third temporary storage box 26. When the accumulated height of the chemical waste sample reaches the third photoelectric sensor 27, the chemical waste sample blocks the light emitted by the third photoelectric sensor 27, and the third photoelectric sensor 27 sends a signal to the control center, and the waste sample processing box 1 is provided with a third sampling door 35 at the lower section corresponding to the third temporary storage box 26, which can collect and process the chemical waste sample in a centralized manner.

[0076] Example 2

[0077] The difference between the present invention and Example 1 is that a chemical treatment box is used to reduce the toughness of high-toughness waste samples, and the disinfectant storage box 21 is filled with chemical reagent cleaning liquid.

[0078] Taking a blood collection bag made of polyvinyl chloride (PVC) as an example, the chemical reagent used to reduce toughness can be:

[0079] 1. Cyclohexanone: Cyclohexanone is a commonly used reagent that can dissolve PVC materials. It can effectively soften the blood collection bag material and facilitate subsequent crushing.

[0080] 2. Ethylene dichloride: Ethylene dichloride is also a reagent that can dissolve PVC and can be used as an alternative to soften PVC materials.

[0081] 3. Tetrahydrofuran: Tetrahydrofuran can also dissolve PVC and is suitable for softening treatment.

[0082] Chemical cleaning fluids can be used:

[0083] 1. Alkaline cleaning agent: Alkaline cleaning agent can effectively remove grease and residual chemical reagents, and has a certain disinfection effect. However, it needs to be rinsed with clean water for a second time after use to prevent residue.

[0084] 2. Neutral detergent: If you are worried that alkaline detergents may corrode or damage certain high-toughness materials, you can choose neutral detergents, which do not require secondary rinsing and leave no residue.

[0085] 3. Water-based cleaning agent: Water-based cleaning agents use water as the reagent, add surfactants and additives, which can effectively remove reagent residues while reducing the impact on the environment. According to the type of dirt and cleaning requirements, you can choose an appropriate water-based cleaning agent.

[0086] Taking the embodiment as an example, the working process is described in detail:

[0087] Under normal circumstances, the first valve 28 is closed. When waste samples need to be put in, the QR code identification layer of the waste samples is placed close to the scanning camera 2. The scanning camera 2 shoots and identifies the QR code identification layer and converts it into an electrical signal and sends it to the control center. The control center confirms the category of the waste sample based on the electrical signal sent by the scanning camera 2 and the waste sample category data. At the same time, the control center opens the first valve 28, and the medical staff puts the waste sample into the delivery port 101, and the waste sample automatically falls along the delivery port 101 to the delivery area 301 of the conveyor belt 3.

[0088] The gravity sensor under the delivery area 301 senses the gravity change and sends a signal to the control center, which closes the first valve 28 and moves the waste sample to the position corresponding to the first feeding pipe 6, the second feeding pipe 11 or the third feeding pipe 25. After the waste sample is pushed to the corresponding waste sample processing device, the gravity sensor senses the gravity change again and sends a signal to the control center, which controls the conveyor belt to reset.

[0089] When the waste sample is a high-toughness waste sample, the conveyor moves to the first feed pipe 6, and the waste sample is pushed into the first feed pipe 6 by the push motor 4 and the push plate 5. Similarly, when the waste sample is a low-toughness waste sample or a chemical waste sample, it is pushed into the second feed pipe 11 or the third feed pipe 25 respectively.

[0090] When the waste sample enters the first feed pipe 6 and accumulates to the height of the first photoelectric sensor 10, the second valve 29 opens, and the waste sample enters the freezer for cooling and toughening. After reaching the preset temperature and the preset freezing time, the third valve 30 opens, and the waste sample enters the first crushing device for crushing. After reaching the preset crushing time, the vibrator 24 is started and the discharge valve is opened, and the crushed waste sample enters the disinfection box 15 from the discharge port along the inclined plate 23.

[0091] When the waste sample enters the second feed pipe 11 and accumulates to the height of the second photoelectric sensor 13, the fourth valve 31 opens, and the waste sample enters the second crushing device for crushing.
