Abstract
Description
Technical Field
[0001] This application relates to the field of syringe auxiliary device technology, and more specifically, to a needle cap removal and engagement auxiliary device for a puncture-proof syringe. Background Technology
[0002] With the continuous development of biomedical research, mice have become an indispensable experimental animal in basic medical research. Due to their rapid reproduction rate, ease of rearing, and standardized culture, they are widely used in research on human diseases and preclinical trials of new drugs. Particularly in the field of animal immunology research, mice are often used to simulate the pathological characteristics of human diseases and test the effectiveness of new drugs.
[0003] In animal immunization experiments, syringes are typically used to inject immunizing agents, such as antigens or cells. The opening and closing of the syringe needle cap is a crucial step in the experiment. Current procedures involve opening the needle cap, drawing the immunizing agent, and then re-capping the needle. This process is repeated multiple times, especially when dozens or even hundreds of needle caps need to be opened and closed each time, requiring frequent needle cap opening and closing actions by the experimenter. While this two-handed method is quick and convenient, it also poses significant safety risks. If the needle punctures the experimenter's finger, especially if it comes into contact with immunizing agents containing antigens, it can lead to serious health problems. Therefore, the need for a safe operating device that ensures both operational efficiency and effective needlestick injury prevention is increasingly urgent. Utility Model Content
[0004] The purpose of this application is to provide an auxiliary device for removing and engaging the needle cap of a syringe that prevents punctures, which can both ensure operational efficiency and effectively prevent needlestick injuries.
[0005] To achieve the above objectives, this utility model provides a needle cap removal and engagement auxiliary device for an anti-puncture syringe, comprising:
[0006] Installation platform;
[0007] A mounting bracket, which is disposed on the mounting platform;
[0008] The auxiliary sleeve is provided on the fixing frame at least two of the auxiliary sleeves, and the auxiliary sleeve is provided with a removal hole for removing the needle cap. The auxiliary sleeve includes a first end and a second end, the first end and the second end are fixedly connected, the diameter of the first end is larger than the diameter of the second end, and the removal hole is provided on the end face of the first end away from the second end, the removal hole extending from the first end to the second end.
[0009] In an optional embodiment, a guide groove is provided on the end face of the first end that is away from the second end.
[0010] In an optional embodiment, a guide protrusion is provided on the outer edge of the end face of the first end that is away from the second end.
[0011] In an optional implementation, it further includes:
[0012] A connecting rope is used to mount the auxiliary sleeve on the fixed frame, and the connecting rope connects the fixed frame and the first end.
[0013] In an optional embodiment, the fixing frame has a U-shaped structure.
[0014] In an optional embodiment, the first end and the second end are coaxially fixedly connected.
[0015] In an optional embodiment, the removal hole extends through the first end and the second end.

[0034] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0035] A syringe generally consists of a syringe barrel, a needle, and a needle cap. The needle is located at the outlet of the syringe barrel, and a needle cap is placed on the needle to prevent contamination and accidental injury to the operator. Before use, the needle cap is placed on the needle; when needed, the needle cap must be removed from the needle. After drawing up the medication, the needle cap must be placed back on the needle.
[0036] Embodiments of this application provide a needle cap removal and engagement auxiliary device for an anti-puncture syringe, including a mounting platform 100, a fixing frame 200, and an auxiliary sleeve 300.
[0037] For example, the mounting table 100 is fixedly mounted on a desktop or can be movably mounted on a desktop.
[0038] like Figure 1 As shown, the mounting bracket 200 is mounted on the mounting platform 100. Exemplarily, the mounting bracket 200 is fixedly mounted on the mounting platform 100, and the fixing connection method is, for example, welding, gluing, snap-fitting, or bolting. The mounting bracket 200 provides a mounting base for the auxiliary sleeve 300.
[0039] like Figure 1 As shown, at least two auxiliary sleeves 300 are provided on the fixing frame 200 so that the needle cap engagement auxiliary device for anti-puncture syringe provided in the embodiments of this application can engage multiple needle caps.
[0040] For example, the mounting bracket 200 is provided with two auxiliary sleeves 300. In another embodiment, the mounting bracket 200 is provided with three auxiliary sleeves 300. Of course, in other embodiments, other numbers of auxiliary sleeves 300 may be provided, such as four, five, or six.
[0041] like Figure 2 and Figure 3 As shown, the auxiliary sleeve 300 is provided with a removal hole 330 for removing the needle cap.
[0042] like Figure 2 and Figure 3As shown, the auxiliary sleeve 300 includes a first end 310 and a second end 320, which are fixedly connected. The diameter of the first end 310 is larger than the diameter of the second end 320. A removal hole 330 is provided on the end face of the first end 310 away from the second end 320. The removal hole 330 extends from the first end 310 to the second end 320.
[0043] The second end 320 provides a handhold for the operator. The second end 320 is a sleeve-shaped structure made of flexible material. During use, the needle cap is inserted into the removal hole 330 from the first end 310. The operator holds the second end 320 tightly, and the inner wall of the removal hole 330 squeezes the needle cap. The operator pulls out the needle with his other hand, leaving the needle cap in the removal hole 330.
[0044] In this application, the diameter of the first end 310 is larger than the diameter of the second end 320, which effectively isolates the operator's hand from the syringe needle and greatly reduces the risk of the needle accidentally pricking the operator's hand.
[0045] In this application, at least two auxiliary sleeves 300 are provided on the fixing frame 200, which allows the operator to handle multiple needle caps at the same time, improving work efficiency and avoiding needle cap confusion.
[0046] In this application, the auxiliary sleeve 300 is disposed on the fixing frame 200, which can prevent the auxiliary sleeve 300 and the needle cap in the auxiliary sleeve 300 from rolling out of order.
[0047] like Figure 2 and Figure 3 As shown, in one embodiment, a guide groove 340 is provided on the end face of the first end 310 away from the second end 320. Exemplarily, the inner wall of the guide groove 340 is inclined in the axial direction of the removal hole 330.
[0048] When the needle cap needs to be removed, the inner wall of the guide groove 340 guides the needle cap to slide into the removal hole 330. The design of the guide groove 340 makes it easier and smoother for the needle cap to slide into the removal hole 330 during removal, improving the needle cap removal efficiency. The inclined inner wall of the guide groove 340 provides a clear sliding path for the needle cap, reducing resistance and deviation during removal, thereby improving removal efficiency.
[0049] When it is necessary to put the needle on the needle cap, the inner wall of the guide groove 340 can guide the needle to slide into the removal hole 330 and install it into the needle cap inside the removal hole 330, reducing the difficulty and operation steps when putting the needle on the needle cap, making the whole process simpler and faster.
[0050] The guide groove 340 makes it easier for the operator to remove and add needle caps without requiring excessive adjustments or calibrations, thus improving the ease of use of the device. The operator can focus more on other aspects of syringe operation without spending excessive time and effort on removing and adding needle caps.
[0051] like Figure 2 and Figure 3 As shown, in one embodiment, a guide protrusion 350 is provided on the outer edge of the end face of the first end 310 away from the second end 320.
[0052] For example, the guide protrusion 350 is disposed on the outer edge of the end face of the first end 310, which expands the guide area to a certain extent and enhances the guide effect.
[0053] The guide protrusion 350 provides a clear positioning point for the removal and placement of the needle cap. When the needle cap needs to be removed, even if the operator's movement error is large, the guide protrusion 350 can still guide the operator to slide the needle cap into the removal hole 330, reducing the blindness and error of the operation.
[0054] To achieve the connection between the fixing frame 200 and the auxiliary sleeve 300, such as Figure 1 As shown, in one embodiment, the needle cap engagement and disengagement auxiliary device for the anti-puncture syringe further includes a connecting rope 400. The auxiliary sleeve 300 is mounted on the fixing frame 200 via the connecting rope 400, and the connecting rope 400 connects the fixing frame 200 and the first end 310.
[0055] For example, such as Figure 1 and Figure 2 As shown, the middle part of the connecting rope 400 crosses the fixed frame 200, so that the connecting rope 400 is suspended on the fixed frame 200. The two ends of the connecting rope 400 are connected to the first end 310, so that the connecting rope 400 is fixedly connected to the first end 310, thereby allowing the auxiliary sleeve 300 to be suspended on the fixed frame 200.
[0056] Of course, in other embodiments, the connecting rope 400 may have other connection methods with the fixing frame 200 and the auxiliary sleeve 300. For example, one end of the connecting rope 400 may be fixedly connected to the auxiliary sleeve 300, and the other end of the connecting rope 400 may be fixedly connected to the fixing frame 200, so that the auxiliary sleeve 300 may be fixedly connected to the fixing frame 200 through the connecting rope 400.
[0057] The connecting rope 400 serves as a flexible connecting element, making the connection between the auxiliary sleeve 300 and the fixing frame 200 more flexible. This connection method allows the auxiliary sleeve 300 to move or adjust within a certain range, adapting to the needs of different usage scenarios.
[0058] like Figure 1As shown, in one embodiment, the fixing frame 200 has a U-shaped structure.
[0059] For example, the mounting platform 100 is horizontally positioned; the fixing frame 200 includes a first rod, a second rod, and a third rod. The first rod is vertically fixed to the mounting platform 100, and one end of the second rod is vertically fixed to the other end of the first rod. One end of the third rod is vertically fixed to the other end of the second rod, and the other end of the third rod is fixedly connected to the mounting platform 100. The first rod, the second rod, and the third rod form a U-shaped fixing frame 200; the fixing connection method is, for example, welding, snap-fit, or threaded connection.
[0060] like Figure 2 As shown, in one embodiment, the first end 310 and the second end 320 are coaxially fixedly connected, and the fixed connection method is, for example, adhesive, snap-fit or integral molding.
[0061] like Figure 2 As shown, in one embodiment, the removal hole 330 extends from the first end 310 to the second end 320. This allows the operator to squeeze the needle cap by holding the second end 320, leaving the needle cap in the removal hole 330.
[0062] like Figure 2 As shown, in one embodiment, the removal hole 330 extends through the first end 310 and the second end 320, so that the removal hole 330 has openings in the first end 310 and the second end 320 respectively to communicate with the outside, so as to balance the air pressure in the removal hole 330.
[0063] When the needle cap is inserted into the removal hole 330 from the first end 310, the gas inside the hole can be smoothly discharged through the opening of the second end 320. This design effectively avoids the situation where the needle cap is hindered from being inserted due to increased air pressure, ensuring that the needle cap can enter the removal hole 330 smoothly and without obstruction. Because the air pressure is balanced, the needle cap will not be stuck or obstructed due to air pressure issues when inserted into the removal hole 330.
[0064] like Figure 1 As shown, in one embodiment, the anti-puncture syringe needle cap removal and engagement auxiliary device further includes a placement rack 500, which is disposed on the mounting platform 100. The placement rack 500 is provided with a placement groove 510 for limiting the syringe. The syringe is placed in the placement groove 510, and the inner wall of the placement groove 510 can prevent the syringe needle from touching the mounting platform 100, etc.
[0065] The placement slot 510 can limit the syringe, ensuring that it will not wobble or slip during operation. This helps to improve the stability and accuracy of the needle cap engagement process and reduce operational errors caused by syringe movement.
[0066] The inner wall design of the placement slot 510 prevents the syringe needle from contacting the mounting platform 100 or other hard objects, thus preventing needle damage or dulling. This is crucial for maintaining the integrity and performance of the syringe.
[0067] For example, the placement rack 500 is movably or fixedly mounted on the mounting platform 100.
[0068] For example, in one embodiment, a first magnetic connector is provided on the mounting platform 100, and a second magnetic connector is provided on the placement rack 500. The first magnetic connector and the second magnetic connector are magnetically connected to each other so that the mounting platform 100 and the placement rack 500 are magnetically connected.
[0069] like Figure 1 As shown, in one embodiment, at least two placement shelves 500 are provided. Exemplarily, in one embodiment, two placement shelves 500 are provided. In another embodiment, three placement shelves 500 are provided. Of course, in some other embodiments, other numbers of placement shelves 500 may be provided, such as four, five, or six, etc.
[0070] The arrangement of multiple racks 500 allows for the simultaneous handling of multiple syringes, significantly improving the efficiency of needle cap removal or related operations. An operator can process one syringe on one rack 500 while simultaneously preparing or handling a syringe on another rack 500, thus parallelizing the workflow.
[0071] like Figure 1 As shown, in one embodiment, the placement rack 500 has at least two placement slots 510.
[0072] For example, such as Figure 1 As shown, in one embodiment, a placement rack 500 is provided with two placement slots 510, the opening directions of the two placement slots 510 are opposite, one placement slot 510 is used to place a syringe, and the other placement slot 510 is used to support the placement rack 500. However, in another embodiment, the two placement slots 510 are in the same direction, so that both placement slots 510 can place syringes.
[0073] In another embodiment, a placement rack 500 is provided with three placement slots 510, which are equidistantly distributed around the axis of the placement rack 500, i.e., the angular interval between the three placement slots 510 is 120°, so that the syringe can be quickly placed even if the placement rack 500 is rolled into other positions.
[0074] In another embodiment, a placement rack 500 is provided with four placement slots 510, which are equidistantly distributed circumferentially along the axis of the placement rack 500, i.e., the angular interval between the four placement slots 510 is 90°. Of course, a placement rack 500 may also be provided with other numbers of placement slots 510, such as five or six.
[0075] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0076] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
