Description

Technical Field

[0001] The invention relates to the field of sharps collection, and in particular to a sharps collection device. Background Art

[0002] After blood drawing or infusion, a large number of sharp objects such as syringes and infusion needles are handled. In clinical work, while handling sharp objects quickly, it is also necessary to ensure safety and prevent needlestick injuries.

[0003] In the prior art, in order to prevent needles in the sharps box from pricking people's hands, the box opening is usually set smaller. However, the box opening is small, and medical staff need to spend time to align the needle with the box opening and throw it in, which is inefficient.

[0004] According to relevant specifications, the volume occupied by the needle in the sharps box cannot exceed 3 / 4 of the capacity. However, in actual operations, it is inaccurate to rely on experience to judge the volume occupied by the needle. If it is judged as less, the volume of the sharps box will be wasted. If it is judged as more, it will be unsafe and there is a risk of the needle puncturing the sharps box. Summary of the invention

[0005] The present invention aims to provide a sharps collecting device, which is convenient for placing sharps and can just fill 3 / 4 of the container.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a sharps collection device, comprising a sharps bucket capable of accommodating sharps, the sharps bucket being provided with a conical cover in the shape of an inverted cone barrel, the inner side of the conical cover being a slide groove, and when the sharps stacked in the sharps bucket are in contact with the lower end of the conical cover, the accumulated volume of the sharps is 3 / 4 of the volume of the sharps bucket.

[0007] The beneficial effects of this program are:

[0008] 1. The inverted cone barrel is in the shape of an inverted cone barrel, that is, the annular cross-section at the upper end is larger than that at the lower end. A chute is formed on the inner side of the conical cover. Sharps enter the sharps barrel with the help of gravity and the chute. By adjusting the opening size at the lower end of the conical cover, the sharps in the barrel are not easy to fall out. It can make it easier for medical staff to put sharps into the sharps barrel, and the sharps in the barrel will not spill out due to the opening being too large.

[0009] 2. When the sharps piled in the sharps bucket are in contact with the lower end of the conical cover, medical staff can just observe that the sharps no longer slide down in the chute. At this time, the accumulated volume of the sharps is 3 / 4 of the volume of the sharps bucket, which just meets the regulatory requirements and does not waste the storage space in the sharps bucket.

[0010] Furthermore, a magnetic part is provided under the sharp instrument barrel, a needle removal plate is provided on the conical cover, a needle removal port is provided on the needle removal plate, the needle removal port includes an insertion hole and a strip hole which are interconnected, the width of the strip hole gradually narrows at one end away from the insertion hole, two strip blades are provided under the strip hole, and the gap between the two strip blades at one end away from the insertion hole gradually becomes smaller.

[0011] Furthermore, the upper 1 / 4 height range of the sharps barrel is a transparent portion, the lower 3 / 4 height range of the sharps barrel is a colored portion, and the conical cover and the transparent portion are at the same height.

[0012] This setting has the following effects:

[0013] 1. The sharps are adsorbed by the magnetic parts at the bottom of the sharps bucket to prevent the sharps from shaking in the sharps bucket. At the same time, the shaking amplitude of the sharps that are not adsorbed is reduced, thereby reducing the extrusion inside the sharps bucket and preventing the sharps from piercing the sharps bucket and causing bacterial infection.

[0014] 2. Insert the infusion needle into the insertion hole, hold the infusion tube and move the needle toward the end of the strip hole until the two strip blades cut off the infusion tube and remove the needle plate. The needle will not bounce around and cause needle stick injuries, which increases the safety of the operation.

[0015] 3. It is more convenient to judge whether the accumulation volume in the sharps bucket exceeds the specification requirements by color.

[0016] Furthermore, it also includes a trolley, which is provided with a sharps collection mechanism, which includes a support plate and a driving cylinder. The magnetic part is an electromagnet, which is fixed on the support plate. The upper end of the output shaft of the driving cylinder is connected to the conical cover. When the trolley moves, the electromagnet is closed.

[0017] Furthermore, an inner cylinder is fixed under the conical cover, the volume of the inner cylinder is 3 / 4 of the sharps barrel, the lower end of the inner cylinder is made of metal, and the lower end of the inner cylinder and the electromagnet can be adsorbed together.

[0018] Furthermore, two spring plate units are arranged in opposition to each other on the support plate. The spring plate assembly includes an arc-shaped clamping plate, a reset spring and a fixing part. The fixing part is arranged on the support plate. The reset spring is horizontally arranged between the arc-shaped clamping plate and the fixing part. The sharp instrument barrel is clamped by the two arc-shaped clamping plates.

[0019] Furthermore, the sharp object collection mechanism also includes a pressing plate, which is a pressing plate that fits the shape of the lower surface of the conical cover. The lower end of the pressing plate is a vertical hole. A pressing cylinder is provided on the conical cover. The lower end of the pressing cylinder output shaft passes through the conical cover and is connected to the pressing plate. A vertical tube is provided at the lower end of the conical cover. The vertical hole and the vertical tube are vertically slidably connected. A number of elastic metal sheets are evenly distributed circumferentially on the vertical hole. The number of elastic metal sheets are combined into an inverted cone barrel-shaped movable cone tip.

[0020] Furthermore, the inner diameter of the vertical tube is 4-6 cm, and the diameter of the lower end of the movable cone tip is less than 2 cm.

[0021] This solution also has the following effects:

[0022] 1. Place the sharps bucket on the support plate of the trolley so that the annular magnet and the electromagnet at the bottom of the sharps bucket are adsorbed together. The conical cover is driven downward by the starting cylinder. The conical cover is on the sharps bucket, and the conical cover drives the inner cylinder to move downward, so that the lower end of the inner cylinder and the electromagnet can be adsorbed together.

[0023] 2. During the use of the sharps bucket, since it is necessary to use a needle remover to cut off the infusion needle, the sharps bucket needs to be fixed by the cooperation of the electromagnet and the inner tube to facilitate the strip blade to relay cutting the catheter connected to the infusion needle; since the sharps enter the sharps bucket from the lower end of the conical cover and the entry position is relatively fixed, as the sharps begin to accumulate in the sharps bucket, the sharps gradually accumulate into a cone shape, so that the sharps will soon come into contact with the lower end of the conical cover, and the medical staff will mistakenly think that the sharps are full, without knowing that part of the space around the inner tube is wasted; in this solution, when the trolley moves, the electromagnet is turned off, and the sharps bucket shakes with the trolley, and the spring plate unit can increase this shaking, and when the trolley stops, the spring plate unit resets the sharps bucket.

[0024] 3. In the initial state, the pressing plate is located between the conical cover and the side wall of the sharps barrel, and the vertical cylinder passes through the middle of the movable cone tip to separate the elastic metal sheet of the movable cone tip; when some sharps are accumulated in the sharps barrel, the sharps are accumulated into a cone shape, and the pressing cylinder drives the pressing plate to move downward. After the elastic metal sheet loses the obstruction of the vertical cylinder, it re-forms into an inverted cone barrel-shaped movable cone tip, and the pressing plate drives the movable cone tip to move downward, thereby pushing the sharps in the middle of the inner cylinder to move around the inner cylinder, so that an inverted cone groove is formed on the upper surface of the sharps pile, so that the sharps can fill the space around the inner cylinder as much as possible.

[0025] 4. After the movable vertebral tip formed by the elastic metal sheet is inserted into the pile of sharp objects many times, the elastic metal sheet is easily curled upward due to the reaction force of the pile of sharp objects, which makes the lower end of the movable vertebral tip no longer sharp, and thus it is not easy to insert into the pile of sharp objects, reducing the pressing effect; in this scheme, when the pressing cylinder drives the elastic metal sheet to move upward, the vertical cylinder scrapes the curled sheet of the elastic metal sheet downward, so that the lower end of the movable vertebral tip formed by the elastic metal sheet becomes sharp again when pressed next time.

[0026] 5. When the sharps on the top of the pile touch the lower end of the conical cover, start the pressing plate to press the sharps pile, and then continue to put in sharps until the sharps on the top of the pile touch the lower end of the conical cover again; start the driving cylinder and the pressing cylinder at the same time, while driving the inner cylinder of the conical cover to move upward, and driving the pressing plate to press downward, so that the sharps in the inner cylinder enter the sharp barrel from the bottom of the inner barrel, and finally all the sharps enter the sharp barrel, the conical cover leaves the sharp barrel, take out the original cover of the sharp barrel, cover the sharp barrel, and seal it. Then use the conical cover with the next sharp barrel.

[0027] 6. Compared with directly lifting the inner tube to allow the sharps to enter the sharps bucket, in this solution, a pressing plate is used to squeeze the sharps pile in advance, so that the inner wall of the inner tube increases the pressure between the sharps around the inner tube, and the lower end of the inner tube is used to break off some sharps with needle tips facing outward, thereby destroying those sharps that are easy to pierce the sharps bucket in advance to avoid the transmission of germs from the sharps.

[0028] 7. In order to make it easier for medical staff to put sharp objects into the sharp object tube, only one pressing cylinder is provided to drive the pressing plate in the present solution. However, this also causes the pressing plate to tilt more and more away from the output shaft of the pressing cylinder after being pressed downward for many times, thereby affecting the pressing efficiency. However, in the present solution, after the pressing plate moves upward, the vertical hole and the vertical tube slide vertically together, thereby correcting the tilt of the pressing plate and ensuring the pressing effect.

[0043] Example 1

[0044] Example 1 is basically as Figure 1-2 As shown: A sharps collection device, including a sharps bucket 100 capable of accommodating sharps, as shown Figure 1 As shown, the sharps barrel 100 is covered with a conical cover 200 in the shape of an inverted cone barrel, the inner side of the conical cover 200 is a slide groove 210, and the conical cover 200 is provided with a needle removal plate 220, and the needle removal plate 220 is provided with a needle removal port 230, and the needle removal port 230 includes an insertion hole 231 and a strip hole 232 that are interconnected, the insertion hole 231 is circular, and the width of the strip hole 232 gradually narrows at one end away from the insertion hole 231, and two strip blades are provided below the strip hole 232, and the strip blades are adhered to the lower surface of the needle removal plate 220 (not shown in the figure), and the gap between the two strip blades at one end away from the insertion hole 231 gradually becomes smaller.

[0045] like Figure 2As shown, a magnetic part is adhered to the bottom of the inner side of the sharps bucket 100, and the magnetic part is a magnet 110. The colored part 120 is yellow in height range L1 at the lower part of the sharps bucket 100, and the transparent part 130 is within height range L2 at the upper part of the sharps bucket 100. L1:L2=1:3, and the upper and lower surfaces of the conical cover 200 and the transparent part 130 are of equal height, that is, when the sharps stacked in the sharps bucket 100 are in contact with the lower end of the conical cover 200, the accumulated volume of the sharps is 3 / 4 of the volume of the sharps bucket 100.

[0046] The inverted cone barrel shape described in this embodiment is an inverted cone barrel shape, that is, the annular cross-section of the upper end is larger than the annular cross-section of the lower end.

[0047] A method of using a sharps collection device is as follows:

[0048] 1. The inverted cone barrel shape is an inverted cone barrel shape, that is, the annular cross-section of the upper end is larger than the annular cross-section of the lower end. A slide groove 210 is formed on the inner side of the conical cover 200. Sharps enter the sharps barrel 100 with the help of gravity and the conical slide groove 210. By adjusting the opening size of the lower end of the conical cover 200, the sharps in the barrel are not easy to fall out. It can make it easier for medical staff to put sharps into the sharps barrel 100, and the sharps in the barrel will not spill out due to the opening being too large.

[0049] 2. When the sharps piled in the sharps bucket 100 are in contact with the lower end of the conical cover 200, the medical staff can just observe that the sharps no longer slide down in the chute 210. At this time, the accumulated volume of the sharps is 3 / 4 of the volume of the sharps bucket 100, which just meets the regulatory requirements and does not waste the storage space in the sharps bucket 100.

[0050] 3. The sharps are adsorbed by the magnetic part at the bottom of the sharps bucket 100 to prevent the sharps from shaking in the sharps bucket 100. At the same time, the shaking amplitude of the sharps that are not adsorbed is also reduced, thereby reducing the extrusion inside the sharps bucket 100 and preventing the sharps from piercing the sharps bucket 100 and causing bacterial infection.

[0051] 4. Insert the infusion needle into the insertion hole 231, hold the infusion tube and drive the needle to move toward the end of the strip hole 232 until the two strip blades cut the infusion tube and remove the cover of the needle plate 220. The needle will not bounce around and cause needle stick injuries, which increases the safety of the operation.

[0052] 5. It is more convenient to judge whether the accumulated volume in the sharps bucket 100 exceeds the specification requirements by color.

[0053] Example 2

[0054] Example 2 is basically the same Figure 3-12 As shown, the difference between Example 2 and Example 1 is that: Figure 4As shown, the sharps bucket 100 is a common disposable plastic sharps bucket 100, which is no longer divided into a transparent part 130 and a colored part 120. The conical cover 200 and the sharps bucket 100 are detachable, and the conical cover 200 is a recyclable metal structure. Figure 4 and Figure 6 As shown, an annular flange 280 is integrally formed on the outer side of the upper surface of the conical cover 200, and the upper end of the sharps barrel 100 contacts the annular flange 280. Fig.10 As shown, a horizontally arranged connecting rod 221 is integrally formed on the needle removing plate 220 .

[0055] like Figure 3 As shown, embodiment 2 is based on embodiment 1 and further includes a trolley 300, the trolley 300 includes a wheel assembly 320 and a shelf 310 for placing medicines, and the trolley 300 is provided with an electric control unit and a sharps collection mechanism.

[0056] like Figure 3 As shown, the sharps collection mechanism includes a support plate 500 and a driving cylinder 510, the support plate 500 and the trolley 300 are bolted together, the electric control unit includes a resistor 440 and a speed sensor 410, a controller 420 and a relay 430 which are electrically connected in sequence, and an electromagnet 450 is arranged on the upper surface of the support plate 500. The circuit diagram of the relay 430, the electromagnet 450 and the resistor 440 is shown in FIG. Fig.12 As shown, in the initial state, the electromagnetic relay 430 and the electromagnet 450 are connected to form a circuit, and the speed sensor 410 can detect whether the wheel assembly 320 is rotating. When the wheel continues to rotate in one direction for more than 2 seconds, the speed sensor 410 sends a signal to the controller 420, and the controller 420 controls the relay 430 to switch the circuit, and then forms a loop with the resistor 440, thereby achieving the purpose of closing the electromagnet 450, that is, when the cart 300 moves, the electromagnet 450 is closed.

[0057] The driving cylinder 510 is bolted to the supporting plate 500, and the upper end of the output shaft of the driving cylinder 510 is bolted to the end of the connecting rod 221 of the conical cover 200. Figure 5 and Figure 6 As shown, an inner cylinder 240 is welded to the lower surface of the conical cover 200. The volume of the inner cylinder 240 is 3 / 4 of the sharps barrel 100. The lower end of the inner cylinder 240 is also made of metal. Figure 3As shown, the lower end of the inner cylinder 240 and the electromagnet 450 can be adsorbed together. The support plate 500 is also provided with two spring plate units arranged on both sides of the sharps barrel 100, and the spring plate assembly includes an arc-shaped clamping plate, a reset spring 530 and a fixing portion 540, the fixing portion 540 is welded on the support plate 500, and the two ends of the reset spring 530 are respectively bonded to the arc-shaped clamping plate and the fixing portion 540, and the reset spring 530 is horizontally arranged between the arc-shaped clamping plate and the fixing portion 540, and the sharps barrel 100 is clamped by the two arc-shaped clamping plates.

[0058] like Figure 6-Figure 11 As shown, the sharps collection mechanism also includes a pressing plate 250, which is a pressing plate 250 that fits the shape of the lower surface of the conical cover 200. The lower end of the pressing plate 250 is a vertical hole, and the needle plate 220 is bolted with a pressing cylinder 260. Fig.11 As shown, the lower end of the output shaft of the pressing cylinder 260 passes through the conical cover 200 and is bolted to the pressing plate 250, as shown in FIG. Figure 7 As shown, a vertical cylinder 270 is welded at the lower end of the conical cover 200, and the inner diameter of the vertical cylinder 270 is 4-6 cm, preferably 5 cm in this embodiment. The chute 210, the vertical cylinder 270 and the inner cylinder 240 are connected in sequence, and the vertical cylinder 270 passes through the vertical hole and is vertically slidably connected to the vertical hole. A plurality of elastic metal sheets 251 are uniformly welded around the vertical hole of the pressing plate 250. In the initial state, as shown in FIG. Figure 8 As shown, a plurality of elastic metal sheets 251 are combined into an inverted cone barrel-shaped movable cone tip, and the diameter of the lower end of the movable cone tip is less than 2 cm, and preferably 1 cm in this embodiment.

[0059] In this embodiment, the controller 420 is electrically connected to all cylinders.

[0060] A method of using a sharps collection device is as follows:

[0061] 1. Place the sharps bucket 100 on the support plate 500 of the trolley 300, so that the annular magnet 110 and the electromagnet 450 at the bottom of the sharps bucket 100 are adsorbed together, and the conical cover 200 is driven to move downward by starting the cylinder. The conical cover 200 is on the sharps bucket 100, and the conical cover 200 drives the inner cylinder 240 to move downward, so that the lower end of the inner cylinder 240 and the electromagnet 450 can be adsorbed together, and the bottom of the sharps bucket 100 is clamped in the middle.

[0062] 2. During the use of the sharps bucket 100, since the needle removal port 230 needs to be used to cut off the infusion needle, the sharps bucket 100 needs to be fixed by the cooperation of the electromagnet 450 and the inner cylinder 240, so that the strip blade can relay to cut the catheter connected to the infusion needle; since the sharps all enter the sharps bucket 100 from the lower end of the conical cover 200, the entry position is relatively fixed, so as the sharps begin to accumulate in the sharps bucket 100, the sharps gradually accumulate into a cone, so that the sharps will soon contact the lower end of the conical cover 200, and medical staff may mistakenly The sharps barrel 100 is already full, but the inner cylinder 240 is not aware of the waste of part of the space around it. In the present solution, when the trolley 300 moves, the electromagnet 450 is turned off. Since the lower part of the sharps barrel 100 loses the fixation of the electromagnet 450, the upper part of the sharps barrel 100 contacts the annular flange 280. Therefore, when the medical staff pushes the trolley 300 back and forth between adjacent buildings, the sharps barrel 100 can shake with the trolley 300, and the spring plate unit can increase this shaking. When the trolley 300 stops, the spring plate unit resets the sharps barrel 100.

[0063] 3. In the initial state, if Figure 6 and Fig. 9 As shown, the pressing plate 250 is located between the conical cover 200 and the side wall of the sharps barrel 100, and the vertical cylinder 270 passes through the middle of the movable cone tip to separate the elastic metal sheet 251 of the movable cone tip; when some sharps are accumulated in the sharps barrel 100, the sharps are accumulated into a cone shape, such as Figure 8 and Fig.11 As shown, the pressing cylinder 260 drives the pressing plate 250 to move downward. After the elastic metal sheet 251 loses the obstruction of the vertical cylinder 270, it re-forms an inverted cone barrel-shaped active cone tip. The pressing plate 250 drives the active cone tip to move downward, thereby pushing the sharp objects in the middle of the inner cylinder 240 to move around the inner cylinder 240, so that an inverted cone groove is formed on the upper surface of the sharp object pile, so that the sharp objects can fill the space around the inner cylinder 240 as much as possible.

[0064] 4. When the sharps on the top of the pile come into contact with the lower end of the conical cover 200, start the pressing plate 250 to press the sharps pile, and then continue to put in the sharps until the sharps on the top of the pile come into contact with the lower end of the conical cover 200 again; start the driving cylinder 510 and the pressing cylinder 260 at the same time, driving the conical cover 200 and the inner cylinder 240 to move upwards, while driving the pressing plate 250 to press downwards, so that the sharps in the inner cylinder 240 enter the sharps barrel 100 from the bottom of the inner cylinder 240, and finally all the sharps enter the sharps barrel 100, the conical cover 200 leaves the sharps barrel 100, and the original cover of the sharps barrel 100 is taken out to cover and seal the sharps barrel 100. Then use the conical cover 200 with the next sharps barrel 100.

[0065] 5. Compared with directly lifting the inner cylinder 240 to allow the sharps to enter the sharps barrel 100, in this solution, the pressing plate 250 is used to squeeze the sharps pile in advance, so that the inner wall of the inner cylinder 240 increases the pressure between the sharps around the inner cylinder 240, and the lower end of the inner cylinder 240 is used to break off some sharps with needle tips facing outward, thereby destroying those sharps that are easy to pierce the sharps barrel 100 in advance to avoid the infection of bacteria by the sharps.

[0066] 6. In order to make it easier for medical staff to put sharp objects into the sharp object tube, only one pressing cylinder is provided to drive the pressing plate in the present solution. However, this also causes the pressing plate to tilt more and more away from the output shaft of the pressing cylinder after being pressed downward for many times, thereby affecting the pressing efficiency. However, in the present solution, after the pressing plate moves upward, the vertical hole and the vertical tube slide together vertically, thereby correcting the tilt of the pressing plate and ensuring the pressing effect.

[0067] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
