Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to a syringe needle sealer. Background Art
[0002] In medical practice, medical instruments with sharp needles are widely used, such as syringes.
[0003] Generally, injections are given to patients with syringes, and the syringes and needles need to be handled separately. Since the needles of medical devices such as syringes are exposed after use, it is easy to stab the relevant personnel, which makes collection and treatment very difficult. Such stab wounds can also cause infection of bacteria. Moreover, when the used needles are reused, there is also a risk of cross infection.
[0004] In the related art, after the use of the syringe, the needle usually needs to be thrown into a sharp box for centralized storage, and finally processed by a professional medical waste treatment agency. However, if the needle cannot be thrown into the sharp box for recycling in time, there is still a large risk of exposure; even if the needle is thrown into the sharp box, since the sharp box needs to reach a certain capacity before it can be sealed, if the sharp box overturns or falls, for some sharp boxes that only have a storage function but no anti-exit function, a large number of used needles may be scattered, thereby forming a risk of stabbing. In addition, in the related art, the needle is usually equipped with a protective cover, but some protective covers are directly stuck on the needle by interference fit, and are very easy to fall off the needle when subjected to external force, thereby exposing the needle. Utility Model Content
[0005] The present application provides a syringe needle sealer, which seals the needle after use, and can prevent the needle from being separated from the sealer, thereby avoiding the risk of needle exposure.

The closing member comprises a rotating arm and a closing block mounted at one end of the rotating arm, and the closing block corresponds to the socket end;
[0010] Wherein, the sealing member is configured to be driven by the needle when the syringe needle is inserted into the cavity so as to rotate, so that the sealing block seals the socket end.
[0011] Furthermore, the cavity comprises a large inner diameter section and a small inner diameter section, the cross section of the large inner diameter section is a V-shaped structure, and the closure member is installed in the large inner diameter section.
[0012] Preferably, the rotating arm comprises an active arm and a passive arm, a rotating member is provided at the connection between the active arm and the passive arm, the closing block is connected to an end of the passive arm away from the active arm, and the passive arm is an elastic structural member.
[0013] Furthermore, the cavity is filled with pipe-blocking mud, and the pipe-blocking mud is located at the closed end.
[0014] Furthermore, the sealer also includes a guide cover, and the guide cover is connected to the socket end of the sealing body.
[0015] Preferably, the guide cover and the sealing body are detachably connected.
[0016] Preferably, the guide cover has a trumpet-shaped structure.

[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0032] In the description of the present application, “multiple” or “several” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0033] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0034] Reference Figure 1-4 , a syringe needle sealer, comprising:
[0035] A sealing body 100, wherein one end of the sealing body 100 is a socket end 101, the other end is a closed end 102, and the interior is a cavity capable of accommodating a syringe needle 500; and
[0036] A closing member 200, wherein the closing members 200 are at least two and are rotatably mounted in the cavity and located at the socket end 101, respectively. The closing member 200 comprises a rotating arm 202 and a closing block 201 mounted at one end of the rotating arm 202, and the closing block 201 corresponds to the socket end 101;
[0037] The closure member 200 is configured to be driven by the needle 500 to rotate when the needle 500 of the syringe 400 is inserted into the cavity, so that the closure block 201 closes the socket end 101 .
[0038] Specifically, when the needle 500 of the syringe 400 is inserted into the cavity of the sealing body 100 through the socket end 101, as shown in FIG. Figure 2 As shown, under the squeezing action of the pintle 501, the closing block 201 is separated and the rotating arm 202 rotates. Figure 3 As shown, the lower ends are close to each other and gather together. During the process of the needle 500 continuing to be inserted, the lower end of the pintle 501 contacts the lower end of the rotating arm 202. At this time, the squeezing effect of the pintle 501 causes the rotating arm 202 to have a tendency to rotate in the opposite direction, so that the closing block 201 moves in a direction close to the pintle 501 and the syringe 400; when the upper end of the pintle 501 passes over the closing block 201 and the needle 500 is completely inserted into the cavity of the sealing body 100, the rotating arm 202 stops rotating, and the closing block 201 stops moving and is stuck between the syringe 400 and the pintle 501.
[0039] When the syringe 400 is pulled out, the needle 500 and the syringe 400 will be separated because the needle plug 501 is stuck by the sealing block 201. After the syringe 400 is pulled out, the sealing block 201 has a blocking effect on the needle 500 on the one hand to prevent the needle 500 from retreating, and on the other hand, it has a sealing effect on the socket end 101, so that the needle 500 is sealed in the cavity of the sealing body 100.
[0040] Since the closing block 201 closes the socket end 101, the needle 500 cannot be accessed from the outside, and the opening of the socket end 101 is usually small (because the needle 500 itself is also small in size), it is difficult to directly pry open the closing block 201 from the outside. Therefore, it is difficult to remove the needle 500 without destroying the sealing body 100, thereby effectively reducing the risk of exposure of the needle 500.
[0041] Reference Figure 2-4 It is understandable that the cavity can also be configured as a large inner diameter section 105 and a small inner diameter section 106 , the cross section of the large inner diameter section 105 is a V-shaped structure, and the closure member 200 is installed in the large inner diameter section 105 .
[0042] Specifically, the large inner diameter section 105 of the cavity corresponds to the socket end 101, and is used to install the closure 200 and accommodate the needle plug 501 of the needle 500. The large inner diameter section 105 is configured as a V-shaped structure with a large opening at one end and a small opening at the other end. The closure 200 is also restricted in the large inner diameter section 105 to form a V-shaped structure with a large opening at one end and a small opening at the other end. Therefore, when the needle 500 is inserted into the cavity from the socket end 101, the needle plug 501 will squeeze the end of the rotating arm 202 away from the socket end 101, thereby making it easier for the rotating arm 202 to rotate, and further drive the closure block 201 to move toward the syringe 400 and the needle 500. Among them, the small inner diameter section 106 is mainly used to accommodate the needle stem 502 of the needle 500.
[0043] Reference Figure 2-4 It can be understood that the rotating arm 202 can include an active arm 2021 and a passive arm 2022, a rotating member 203 is provided at the connection between the active arm 2021 and the passive arm 2022, the closing block 201 is connected to one end of the passive arm 2022 away from the active arm 2021, and the passive arm 2022 is an elastic structural member.
[0044] It should be noted that the active arm 2021 and the passive arm 2022 can be made of the same material or different materials. In addition, the active arm 2021 can be an elastic structural part or a non-elastic structural part, but it is necessary to ensure that the passive arm 2022 is an elastic structural part, for example, the passive arm 2022 is an elastic plastic part, a metal part, etc. Among them, the active arm 2021 and the passive arm 2022 can be connected by hot-melt connection, clamping, threaded connection or other existing connection methods, and it is only necessary to ensure that the active arm 2021 and the passive arm 2022 can be linked. It should also be noted that the rotating member 203 is to install the entire rotating arm 202 in the inner cavity of the sealing body 100, rather than being used for the connection between the active arm 2021 and the passive arm 2022, wherein the rotating member 203 can be a rotating shaft structure.
[0045] It can be understood that the passive arm 2022 described in the present application is an elastic structural part. When the needle 500 is inserted, the front end of the syringe 400 will block the closing block 201, and the closing block 201 cannot completely close the socket end 101; as the needle 500 is inserted, the rotating arm 202 further rotates, and the passive arm 2022 will produce elastic bending; when the syringe 400 is pulled out, the passive arm 2022 returns to its original state due to the elastic effect, so that the closing block 201 can move further to complete the complete closure of the socket end 101.
[0046] Reference Figure 2-4It is understandable that the cavity may also be filled with pipe plugging mud 107 , and the pipe plugging mud 107 is located at the closed end 102 .
[0047] Specifically, since the tube-blocking mud 107 is provided at the closed end 102 in the cavity, after the needle 500 is inserted, the tube-blocking mud 107 will block the needle stem 502, and even if the needle 500 is violently removed, it cannot be reused.
[0048] Reference Figure 1 and 2 It can be understood that the sealer may further include a guide cover 300 , and the guide cover 300 is connected to the socket end 101 of the sealing body 100 .
[0049] Specifically, the guide cover 300 can play a protective role. When the needle 500 is inserted into the sealing body 100, the guide cover 300 can protect the hand holding the sealing body 100 to avoid being stabbed by the needle 500.
[0050] It is understandable that in the related art, a needle 500 protective cover is also provided. However, in daily care, after the nurse uses the syringe 400 to inject the patient, in order to avoid occupational exposure, the correct operation is not to put the protective cover back on. One of the most important reasons is that the opening of this protective cover is small, and it is very likely that the needle 500 will cause a puncture accident during the process of putting it back on. In this application, the guide cover 300 provided on the sealing body 100 can effectively prevent the needle 500 from puncturing.
[0051] Reference Figure 2-4 It is understandable that the guide cover 300 may be a trumpet-shaped structure, or may be other shapes and structures having a certain area protection function.
[0052] Reference Figure 2-4 It can be understood that the guide cover 300 and the sealing body 100 are detachably connected.
[0053] Specifically, a connecting sleeve 301 is provided at one end of the guide cover 300, wherein the connecting sleeve 301 and the sealing body 100 may be detachably connected by threaded connection, clamping connection, bonding or other prior art methods. Thus, the guide cover 300 is configured to be reusable, thereby reducing the use cost.
[0054] Reference Figure 2-4 It can be understood that the end of the closing block 201 away from the rotating arm 2021 is set as a wedge-shaped structure.
[0055] Specifically, one end of the closing block 201 is set as a wedge-shaped structure, which can more conveniently allow the closing block 201 to be inserted between the needle plug 501 and the syringe 400. When the syringe 400 is pulled out, the needle 500 can be clamped by the closing block 201, thereby completing the separation of the syringe 400 and the needle 500.
[0056] Reference Figure 2-4 It can be understood that a stopper 103 is also provided on the outer wall of the sealing body 100 .
[0057] Specifically, by providing the stopper 103 , the positioning connection between the guide cover 300 and the sealing body 100 is facilitated.
[0058] Reference Figure 2-4 It can be understood that the outer wall of the sealing body 100 is also provided with anti-slip textures.
[0059] Specifically, when in use, the sealing body 100 provided with protective patterns is more convenient to hold. Among them, the anti-slip patterns can be selected from existing technical means.
[0060] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the principles of the present application shall be included in the protection scope of the present application.
