Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to a medical waste bin. Background Art
[0002] Medical waste needs to be disposed of separately. For example, infectious waste needs to be thrown into special trash cans, while sharp objects such as needles and tweezers need to be thrown into special sharps boxes.
[0003] However, in actual operation, sometimes medical staff will accidentally throw sharp objects such as needles into general medical waste bins. For example, after removing the needle for a patient receiving an IV drip, some medical staff will insert the infusion needle into the gourd of the infusion tube to prevent the needle from hurting people; but in the subsequent processing, some medical staff will, due to negligence, directly throw the entire infusion tube into a general medical waste bin. The presence of the needle will cause the garbage bag to be punctured and leak, causing the spread of pollutants.
[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content
[0005] In order to solve the technical problem in the prior art that medical staff may mistakenly throw sharp objects such as needles into medical waste bins, the present application proposes a medical waste bin that can use a metal detector to detect whether the waste thrown into the bin contains metal sharps, so as to avoid medical waste leakage or sharp injuries caused by poor classification.
[0006] The medical waste bins proposed in this application include:
[0007] a bracket, wherein an opening is formed on the bracket;
[0008] and a metal detector, which is connected to the bracket and located above the opening, and is used for detecting metal waste thrown into the medical waste bin and sounding an alarm.
[0009] Furthermore, the medical waste bin also includes a baffle, which is movably connected to the bracket, and the opening is closed or opened by moving the baffle.
[0010] The medical waste bin also includes a driving assembly; the driving assembly includes a supporting arm, one end of the supporting arm is slidably connected to the bracket, and the metal detector is connected to the end of the supporting arm away from the bracket.
[0011] The driving assembly also includes a driving motor, which is connected to the bracket and connected to an end of the supporting arm that is away from the metal detector.
[0012] Furthermore, the medical waste bin also includes a bin body, which is located in the bracket, with a bin mouth on the bin body facing the opening, and medical waste enters the bin mouth through the opening.
[0013] Furthermore, a shielding cover is connected to the bracket, and the metal detector is located inside the shielding cover.
[0014] Furthermore, an observation window is provided on the shielding cover, and the observation window is located on a side of the shielding cover away from the bracket.
[0015] Furthermore, a slide groove is provided on the shielding cover, and the metal detector enters into the shielding cover through the slide groove.
[0016] Furthermore, the shielding cover is provided with an inlet, through which garbage enters the shielding cover.
[0017] Furthermore, a hatch is provided on the shielding cover, and the hatch is movably connected to the shielding cover, and the movable hatch is used to open or close the inlet.
[0018] The utility model is beneficial in that the metal detector can be used to scan whether there are sharp objects in medical waste, so that medical staff can timely screen out the sharp objects that are accidentally lost, so as to avoid sharp objects that injure people or medical waste leakage. The baffle can provide support and a scanning platform for the waste to be thrown into the medical waste bin, which is convenient for the metal detector to scan. After the scan is completed, the medical waste on the baffle can enter the bin. The shielding cover can shield external interference, so that the metal detector cannot scan the metal outside the shielding cover, so as to avoid false alarms of the metal detector and improve the accuracy of the scanning results.

[0028] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0029] Sharps in medical waste refer to various items used in medical, research, or veterinary practice that have the risk of puncturing or cutting the skin. This type of waste generally needs to be handled separately because it may carry pathogens such as bacteria and viruses.
[0030] For the convenience of description, the end of the bracket 10 connected to the shielding cover 60 is defined as the upper end.
[0031] Sharps in medical waste refer to various items used in medical, research, or veterinary practice that have the risk of puncturing or cutting the skin. This type of waste generally needs to be handled separately because it may carry pathogens such as bacteria and viruses.
[0032] For wastes of relatively large size, such as scalpels, since they are relatively conspicuous, medical staff generally will not accidentally throw them into general medical waste bins. However, for wastes of smaller size, such as needles, medical staff need to pay more attention. For example, the needle of an infusion tube. Generally speaking, the needle on the infusion tube is a sharp device and needs to be discarded in a sharps box, and the main body of the infusion tube needs to be thrown into a general medical waste bin; however, in the actual implementation process, after the nurse removes the needle for the patient, in order to prevent the needle from injuring people, they often choose to insert the needle into the gourd on the infusion tube; although the above operation avoids needle injuries, when medical staff discard the infusion tube, it will be easy to throw the infusion tube and the needle into the medical waste bin together, causing the sharp device to be accidentally thrown into a general medical waste bin.
[0033] In order to solve the above technical problems, the present application proposes a medical waste bin, which can use a metal detector 20 to scan medical waste and perform inspection before the medical waste is put into the bin to prevent sharp metal objects from being accidentally thrown into the medical waste bin.
[0034] See also Figure 1 and Figure 2 The medical waste bin proposed in this embodiment includes a bracket 10 and a metal detector 20. Among them, an opening 11 is formed on the bracket 10, and medical waste needs to pass through the above opening 11 when it is discarded; the function of the bracket 10 is to provide support for the metal detector 20. The bracket 10 in this embodiment is generally in the shape of a square cylinder, and its interior can accommodate a container for medical waste. The metal detector 20 is connected to the bracket 10 and is located above the opening 11. The metal detector 20 is used to scan the waste thrown into the medical waste bin to detect whether the waste contains metal. When the metal detector 20 detects metal, it will sound an alarm to remind medical staff that there is metal in the waste and there is suspected metal sharps, so that the medical staff can conduct a secondary inspection and remove the sharps, thereby preventing the sharps from entering the medical waste bin.
[0035] The metal detector 20 can refer to the detectors used for security inspection on the market, which will sound an alarm after scanning metal to remind security personnel to conduct inspection. In the present application, the metal detector 20 will also sound an alarm after scanning metal garbage to remind medical staff to conduct a secondary inspection of medical waste.
[0036] Furthermore, the medical waste bin proposed in this embodiment also includes a barrel body 50, which is located in the bracket 10, and the barrel mouth on the barrel body 50 faces the opening 11, and the medical waste enters the barrel mouth through the opening 11. The barrel body 50 is a container for holding medical waste. When the medical waste is discarded, it must first pass through the opening 11 on the bracket 10, and then enter the barrel body 50 through the barrel mouth. In some embodiments, a barrel cover capable of closing the barrel mouth is connected to the barrel body 50, and a pulley is also provided at the bottom of the barrel body 50 to facilitate the user to take the barrel body 50 out of the bracket 10. When in use, the barrel body 50 first needs to be placed in the bracket 10; correspondingly, a storage space for accommodating the barrel body 50 is formed inside the bracket 10. In order to prevent leakage of medical waste, the side wall of the lower part of the bracket 10 should be closed, so that the barrel body 50 is enclosed inside the bracket 10; an inlet and outlet for the barrel body 50 to enter and exit need to be provided on the side wall. In some embodiments, in order to further seal the barrel body 50, a movable door for sealing the inlet and outlet is provided on the bracket 10.
[0037] See also Figure 4 In this embodiment, the medical waste bin further includes a baffle 12, which is movably connected to the bracket 10, and the opening 11 is closed or opened by moving the baffle 12. Since the medical waste is directly thrown into the barrel body 50, the falling speed of the medical waste is relatively fast, which may cause inaccurate detection results of the metal detector 20, and the above operation is not conducive to medical staff to sort out metal sharps from the medical waste. Therefore, the bracket 10 in this embodiment is connected with a baffle 12, and the baffle 12 is rotatably connected to the bracket 10, specifically, it is rotatably connected to the edge of the opening 11 on the bracket 10. Of course, it is easy to think that the baffle 12 can also be connected to the bracket 10 in a manner such as a sliding connection. The baffle 12 can provide a scanning platform for the metal detector 20. When in use, the medical waste needs to be placed on the baffle 12 first. The medical waste will not enter the barrel body 50 due to the obstruction of the baffle 12. Then, the metal detector 20 will scan the medical waste. After completing the scanning and removing the sharp metal objects, the baffle 12 can be moved to tilt the baffle 12 downward, so that the medical waste on the baffle 12 falls into the barrel body 50.
[0038] See also Figure 3Furthermore, a rotating assembly 30 for driving the baffle 12 to rotate is also provided on the bracket 10, wherein the rotating assembly 30 includes a cylinder 31, a first connecting arm 32 and a second connecting arm 33, wherein the cylinder 31 is connected to the bracket 10, and a rotating shaft hole is provided on the side of the baffle 12 facing the opening 11, the baffle 12 is hinged to the first connecting arm 32 through the rotating shaft hole, the end of the first connecting arm 32 facing away from the baffle 12 is hinged to the second connecting arm 33, and the end of the second connecting arm 33 facing away from the first connecting arm 32 is connected to the cylinder 31, so that the rotation of the baffle 12 can be controlled by controlling the lifting and lowering of the cylinder 31.
[0039] In this embodiment, in order not to interfere with the rotation of the first connecting arm 32 and the second connecting arm 33, a notch is further provided on the bracket 10. The notch and the cylinder 31 are located on the same side of the bracket 10. The first connecting arm 32 and the second connecting arm 33 enter the internal space of the bracket 10 from the external space through the notch.
[0040] See also Figure 4 Furthermore, in order to ensure that the medical waste on the baffle 12 can accurately fall into the barrel body 50, preferably, the cross-sectional area of the opening 11 on the bracket 10 in the horizontal plane is smaller than the cross-sectional area of the barrel mouth on the barrel body 50 in the horizontal plane. In addition, in the present embodiment, a groove 13 is formed at the upper end of the bracket 10, the groove 13 is recessed toward the inside of the bracket 10, and the opening 11 is located on the bottom of the groove 13. In this way, when scanning, the baffle 12 blocks the opening 11 so that the bottom of the groove 13 is blocked, so that the medical waste will be placed in the groove 13, thereby limiting the area of the medical waste spread, so as to prevent the medical waste from not falling into the barrel body 50 completely due to the spread area of the medical waste being larger than the cross-sectional area of the barrel mouth. Preferably, the side wall of the groove 13 is inclined at a certain angle, which can increase the unfolding area of medical waste and the amount of medical waste that can be processed in a single scan compared to a vertical groove wall. In addition, the inclined groove wall can also guide the medical waste to fall into the opening 11.
[0041] Furthermore, a forced switch is also provided on the bracket 10, and the forced switch can directly control the rotation of the baffle 12. The forced switch is electrically connected to the cylinder 31. In some cases, medical waste made of metal materials is not necessarily a sharp object, so the above medical waste also needs to be thrown into a medical waste bin instead of a sharps box, but the above medical waste will still trigger the alarm of the metal detector 20. Therefore, a forced switch is also required. After the metal detector 20 completes the first scan, issues an alarm, and the medical staff completes the secondary inspection, if it is confirmed that there is no sharp object in the medical waste, the medical staff can control the forced switch to control the rotation of the baffle 12 so that the medical waste falls into the barrel body 50.
[0042] See also Figure 3 , the medical waste bin also includes a driving assembly 40; the driving assembly 40 includes a support arm 42, one end of the support arm 42 is slidably connected to the bracket 10, and the metal detector 20 is connected to the end of the support arm 42 away from the bracket 10. The support arm 42 enables the metal detector 20 to be located above the opening 11, so that the metal detector 20 can be aligned with the opening 11. Preferably, the support arm 42 in this embodiment should be made of non-metallic material. In addition, the metal detector 20 can be connected to the support arm 42 by a connection method such as snap-on, and the detachable connection can also facilitate maintenance personnel to maintain the metal detector 20. Preferably, the connection structure between the metal detector 20 and the support arm 42 should be made of non-metallic material as much as possible to avoid false alarms of the metal detector 20.
[0043] Furthermore, the driving assembly 40 also includes a driving motor 41, which is connected to the bracket 10, and the driving motor 41 is connected to the end of the support arm 42 away from the metal detector 20. Since the scanning range of a single metal detector 20 is limited, it is difficult to cover the entire opening 11 and the baffle 12. Therefore, in order to enable the scanning range of the metal detector 20 to cover the entire opening 11, the bracket 10 is also connected to the driving motor 41, and the driving motor 41 is used to drive the support arm 42 to slide, thereby driving the metal detector 20 to slide, so that the metal detector 20 can scan the entire opening 11, thereby achieving a comprehensive scan of medical waste.
[0044] Preferably, the driving motor 41 in the present embodiment is a linear motor, and the linear motor includes a guide rail and a slider, and the slider is slidably connected to the guide rail. The guide rail is connected to the bracket 10, and the end of the support arm 42 that is away from the metal detector 20 is connected to the slider. Specifically, the support arm 42 in the present embodiment is generally L-shaped, and includes a horizontal arm 421 and a vertical arm 422. The metal detector 20 is connected to the end of the horizontal arm 421 that is away from the vertical arm 422, and the end of the vertical arm 422 that is away from the horizontal arm 421 is connected to the slider. Generally speaking, the cross-sectional size of the metal detector 20 is smaller than the size of the barrel mouth, so a single metal detector 20 is difficult to scan all medical wastes. Since the slider can drive the metal detector 20 to slide by sliding on the guide rail, it can be achieved by sliding the metal detector 20 so that the scanning range of the metal detector 20 covers the entire opening 11, thereby ensuring the accuracy of detection. Preferably, during a single scanning process, the slider performs a reciprocating motion on the guide rail, so that the metal detector 20 can pass through the opening 11 twice, and the scanning accuracy is ensured by detecting the medical waste twice, thereby screening out metal sharp objects in the medical waste.
[0045] See also Figure 1 , Figure 2 as well as Figure 3 Furthermore, a shielding cover 60 is connected to the bracket 10, and the metal detector 20 is located in the shielding cover 60. During the scanning process of the metal detector 20, metal other than medical waste on the baffle 12 may sometimes be identified, thereby causing a false alarm. In order to avoid the occurrence of false alarms, the bracket 10 in the present application is also connected to the shielding cover 60. The shielding cover 60 can make the entire scanning process be carried out in the shielding cover 60, thereby eliminating external interference factors and improving the accuracy of the scanning.
[0046] The shielding cover 60 in this embodiment is roughly in the shape of a square shell, and one end of the shielding cover 60 with a cover opening is connected to the upper end of the bracket 10, so that the entire shielding cover 60 is covered above the opening 11 of the bracket 10. In order to facilitate the user to observe the situation inside the shielding cover 60, an observation window is provided on the shielding cover 60, and the observation window is located on the side of the shielding cover 60 away from the bracket 10. The shielding cover 60 in this embodiment is provided with four side surfaces and a bottom surface, and the observation window is provided on the bottom surface. Metals such as lead are provided on the four side surfaces of the shielding cover 60 in this embodiment so that the signal emitted by the metal detector 20 can be shielded. Since the signal of the metal detector 20 is emitted toward the bracket 10, there is no need to worry about the signal emitted by the metal detector 20 being emitted from the side of the shielding cover 60 away from the bracket 10, so an observation window can be provided on the bottom surface.
[0047] Furthermore, a slide groove 63 is provided on the shielding cover 60, and the metal detector 20 enters the shielding cover 60 through the slide groove 63. In order to ensure that the shielding cover 60 does not block the sliding of the support arm 42, a slide groove 63 is provided on the shielding cover 60, and the slide groove 63 can match the cross arm 421 of the support arm 42, thereby preventing the shielding cover 60 from blocking the sliding of the support arm 42.
[0048] In addition, the shielding cover 60 is also provided with an inlet 61, through which garbage enters the shielding cover 60. Correspondingly, the shielding cover 60 is also provided with a hatch 62, which is movably connected to the shielding cover 60, and the hatch 62 is moved to open or close the inlet 61. The inlet 61 is provided on the side of the shielding cover 60.
[0049] When using the medical waste bin proposed in the present application, the user first needs to open the hatch 62 and place the medical waste on the baffle 12, then close the hatch 62 and start the metal detector 20. After the metal detector 20 completes the scan, if the metal detector 20 does not sound an alarm, the baffle 12 will automatically slide downward under the drive of the cylinder 31, so that the medical waste enters the barrel body 50; if the metal detector 20 sounds an alarm, the medical staff needs to open the hatch 62 to conduct a secondary check on the medical waste to confirm whether there are sharp metal objects, and then close the hatch 62 again and start the metal detector 20. If the metal detector 20 does not sound an alarm in the second scan, the processing flow is the same as above; if the metal detector 20 sounds an alarm again, if the medical staff can determine that there are no sharp metal objects in the medical waste, they need to press the forced switch to allow the medical waste to enter the barrel body 50.
[0050] Furthermore, in some embodiments, in order to facilitate medical staff to handle metal sharps screened from medical waste, a sharps box is connected to the outer space of the bracket 10. In some embodiments, in order to prevent the patient's family from throwing ordinary household garbage into the medical waste bin, an identification device such as a card reader or a camera can be set at the hatch 62 of the shielding cover 60 to restrict non-medical staff from opening the hatch 62, thereby preventing household garbage from being thrown into the medical waste bin.
[0051] In summary, the metal detector 20 can be used to scan whether there are sharp objects in the medical waste, so that medical staff can timely screen out the sharp objects that are accidentally lost, so as to avoid sharp objects causing injuries or medical waste leakage due to the accidental loss of sharp objects. The baffle 12 can provide support and a platform for scanning for the waste to be thrown into the medical waste bin, which is convenient for the metal detector 20 to scan. After the scan is completed, the medical waste on the baffle 12 can enter the barrel body 50. The shielding cover 60 can shield external interference, so that the metal detector 20 cannot scan the metal outside the shielding cover 60, so as to avoid false alarms of the metal detector 20 and improve the accuracy of the scanning results.
[0052] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
