Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a needle cap to prevent needlestick injuries. Background Technology

[0002] Needlestick injuries refer to skin injuries caused by medical sharp instruments such as injection needles, suture needles, and puncture needles. They have become a serious occupational hazard for medical staff. Currently, in clinical work, after an intravenous infusion is completed, nurses need to remove the needle and recycle the infusion bottle. If the needle cap is not replaced during transportation, the needle is likely to cause a puncture injury. If the needle cap is replaced, the existing needle cap is likely to cause a needlestick injury during the replacement process.

[0003] To address the problem of needlestick injuries, many medical professionals have conducted research and invented numerous practical patents for preventing needlestick injuries. However, most of these are needle cap supports. While existing technologies can effectively prevent needlestick injuries, they are relatively bulky and inconvenient to use in clinical work. Furthermore, these devices are expensive to manufacture and not easily popularized. Therefore, to address these issues, we propose a needle cap for preventing needlestick injuries. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a needle cap that prevents needlestick injuries, effectively preventing needlestick injuries while being easy for medical personnel to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a needle cap for preventing needlestick injuries, comprising a needle cap body, an auxiliary base, and a connector. One end of the needle cap body is open for covering the needle tip. The auxiliary base is located at the closed end of the needle cap body for positioning the needle cap body. The auxiliary base includes a suction cup and an adhesive component inside the suction cup. The connector is located between the closed end of the needle cap body and the auxiliary base for connecting the auxiliary base to the needle cap body.

[0006] The beneficial effects of this utility model are as follows: the needle cap body is connected to the auxiliary base through the connector. When the needle cap body is removed from the needle, the suction cup and adhesive are adsorbed and fixed to the placement surface. When the needle cap body is restored, the needle is inserted into the needle cap body, and then the needle cap body is separated from the placement surface. This avoids needle pricks when restoring the needle cap body. At the same time, the fixing effect of the auxiliary base on the needle cap body prevents the needle cap body from being lost or falling off, making it convenient for medical staff to use.

[0007] To connect the needle cap body to the auxiliary base;

[0008] As a further improvement to the above technical solution: the connector is a connecting plate, which is fixedly connected between the needle cap body and the auxiliary base.

[0009] The beneficial effect of this improvement is that by setting up the connector, the needle cap body and the auxiliary base can be fixedly connected, preventing the auxiliary base from falling off during use.

[0010] To allow for flexible use of the auxiliary base;

[0011] As a further improvement to the above technical solution: the connector is an elastic sleeve with at least one open end, one end of the elastic sleeve is fixedly connected to the suction cup component, and the open end of the elastic sleeve is detachably connected to the closed end of the needle cap body.

[0012] The beneficial effects of this improvement are as follows: by setting up the elastic sleeve, the elastic sleeve is put on the needle cap body when in use, and the elastic sleeve can be removed after use and then connected to other needle cap bodies. It can be reused multiple times, making it more flexible and convenient.

[0013] To ensure the adhesive can be reused effectively;

[0014] As a further improvement to the above technical solution: the number of adhesive components is multiple sets, and each set of adhesive components includes an adhesive layer and a release layer connected to the adhesive layer.

[0015] The beneficial effects of this improvement are: multiple adhesive components are connected layer by layer, and the release layer on the lower adhesive component is connected to the adhesive layer on the upper adhesive component. After one use, when it is needed for the next use, the bottom adhesive component can be peeled off to expose the adhesive layer on the upper adhesive component, thus avoiding the weakening of the adhesive strength of the adhesive components when reused.

[0016] In order to effectively increase adsorption capacity;

[0017] As a further improvement to the above technical solution: the suction cup component includes an adsorption part one and an adsorption part two integrally formed and connected to the adsorption part one. The diameter of the adsorption part one is smaller than the diameter of the adsorption part two, and the adhesive is located inside the adsorption part one.

[0018] The beneficial effects of this improvement are as follows: by connecting the adhesive to the inside of the first adsorption part, when adsorption occurs, the second adsorption part is in contact with the placement surface as a whole, the contact area between the second adsorption part and the placement surface is large, the adsorption force is better, and the adhesive can also be well bonded, increasing the adsorption force.

[0019] To make it easier to remove the adhesive parts;

[0020] As a further improvement to the above technical solution: each set of adhesive components is provided with a tear-off part.

[0021] The beneficial effect of this improvement is that the tear-off part makes it easy to peel off the used adhesive parts. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0031] like Figure 1-7As shown, a needle cap for preventing needlestick injuries includes a needle cap body 1, an auxiliary base, and a connector. One end of the needle cap body 1 is open, used to cover the needle tip. The auxiliary base is located at the closed end of the needle cap body 1 and is used to position the needle cap body 1. The auxiliary base includes a suction cup 201 and an adhesive component 202 located inside the suction cup 201. The connector is located between the closed end of the needle cap body 1 and the auxiliary base, used to connect the auxiliary base and the needle cap body 1. In use, the needle cap body 1 is removed from the needle tip, and then the open end of the needle cap body 1 is facing upwards. Due to the connecting effect of the connector, The auxiliary base is connected to the needle cap body 1. The auxiliary base is then bonded to the placement surface using suction cup 201 and adhesive 202. This ensures that the auxiliary base can be effectively fixed on both smooth and uneven surfaces. During needle use, the needle cap body 1 remains in a fixed position and will not fall off or be lost. When the needle cap needs to be restored, the needle can be directly inserted into the needle cap body 1 with the opening facing upwards. This prevents needle pricks during use. The auxiliary base's fixation of the needle cap body 1 also prevents it from being lost or falling off, making it convenient for medical personnel to use.

[0032] like Figure 1 As shown, the first embodiment provided by this utility model is as follows: the connecting member is a connecting plate 3, which is fixedly connected between the needle cap body 1 and the auxiliary base. The connecting plate 3 can be integrally formed and connected with the needle cap body 1 during production. The connecting plate 3 fixes the needle cap body 1 and the auxiliary base together, so that the auxiliary base will not fall off at will during use, which is more convenient during use.

[0033] like Figure 2 As shown, the second embodiment provided by this utility model is as follows: the connecting member is an elastic sleeve 4 with at least one open end. One end of the elastic sleeve 4 is fixedly connected to the suction cup 201, and the open end of the elastic sleeve 4 is detachably connected to the closed end of the needle cap body 1. The elastic sleeve 4 can be made of rubber, silicone, or other materials. When in use, the elastic sleeve 4 is placed on the closed end of the needle cap body 1. Under the elastic action of the elastic sleeve 4, the elastic sleeve 4 and the needle cap body 1 are tightly attached, so that the auxiliary base is connected to the needle cap body 1. After use, the elastic sleeve 4 can be removed from the needle cap body 1 and connected to other needle cap bodies 1 for use. It is more flexible. Unlike the first embodiment, the auxiliary base will not fall off the needle cap body 1 when in use, but the flexibility of use is limited. The second embodiment can be adapted to multiple needle cap bodies 1, reused, and is more flexible. At the same time, it reduces the cost of wear and tear. In actual use, it can be customized according to the needs of use.

[0034] Furthermore, the number of adhesive components 202 is multiple sets, and each set of adhesive components 202 includes an adhesive layer 2021 and a release layer 2022 connected to the adhesive layer 2021. The multiple sets of adhesive components 202 are connected layer by layer. The release layer 2022 on the lower adhesive component 202 is connected to the adhesive layer 2021 on the upper adhesive component 202. After one use, when it is needed for the next use, the bottom adhesive component 202 can be peeled off to expose the adhesive layer 2021 on the upper adhesive component 202, so as to avoid the adhesive strength of the adhesive component 202 weakening when reused.

[0035] Furthermore, the suction cup component 201 includes a first suction part 2011 and a second suction part 2012 integrally formed and connected to the first suction part 2011. The diameter of the first suction part 2011 is smaller than the diameter of the second suction part 2012, and the adhesive member 202 is located inside the first suction part 2011. Both the first suction part 2011 and the second suction part 2012 can be made of elastic materials such as rubber or silicone, which can be adsorbed and fixed to the placement surface. During use, the interior of the first suction part 2011... The adhesive component 202 is provided so that when the second adsorption part 2012 contacts the placement surface, the second adsorption part 2012 can fully contact the placement surface, avoiding interference from the adhesive component 202 that affects the adsorption effect of the second adsorption part 2012. The adhesive component 202 can also be well bonded and fixed to the placement surface. When it is necessary to replace the adhesive component 202, the second adsorption part 2012 and the first adsorption part 2011 can be flipped upwards and outwards to expose the adhesive component 202, making it easy to peel off the used adhesive component 202.

[0036] Furthermore, each set of adhesive components 202 is provided with a tear-off part 5. Due to the setting of the adhesive layer 2021, the release layer 2022 between the two adhesive components 202 is tightly bonded to the adhesive layer 2021. The setting of the tear-off part 5 makes it easy to tear off the adhesive component 202 after use.

[0037] The working principle and usage process of this utility model are as follows: When using this device, if the auxiliary base is fixedly connected to the needle cap body 1, first separate the needle cap body 1 from the auxiliary base, then press the needle cap body 1, simultaneously causing the auxiliary base to contact the placement surface. The suction cup and adhesive 202 will adhere and fix to the placement surface. When it is necessary to restore the needle cap body 1, hold the needle in one hand and directly insert the needle tip into the needle cap body 1. Then separate the auxiliary base from the placement surface for subsequent medical waste disposal. If the auxiliary base and the needle cap body 1 are detachably connected, first put the elastic sleeve 4 on the closed end of the needle cap body 1, and then observe the adhesion. If component 202 has been used, the first adsorption part 2011 and the second adsorption part 2012 need to be turned upwards and outwards to expose the adhesive component 202. Then, the bottom layer of adhesive component 202 is peeled off by the peeling part 5 to expose the new adhesive component 202. After separating the needle tip from the needle cap body 1, the needle cap body 1 is pressed down, and the auxiliary base is brought into contact with the placement surface. The suction cup and the adhesive component 202 are adsorbed and fixed to the placement surface. When it is necessary to restore the needle cap body 1, hold the needle with one hand and insert the needle tip directly into the needle cap body 1. Finally, separate the elastic sleeve 4 from the needle cap body 1 for connection with other needle cap bodies 1.
