Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an intravenous injection patch. Background Art

[0002] Intravenous injection is a medical method that involves injecting liquid substances such as blood, medicine, and nutrient solution directly into the vein. Intravenous injection can be divided into transient and continuous. Transient intravenous injection is usually injected directly into the vein with a syringe, which is the common "injection"; continuous intravenous injection is implemented by intravenous drip, commonly known as "drip". During use, in order to avoid the problem of the infusion tube falling off due to human error and device displacement, the infusion tube, needle holder tube, and needle are often required to be fixed at the injection site.

[0003] At present, the needle, needle holder tube and infusion tube are generally fixed by sticking multiple pieces of adhesive tape or multiple fixing dressings (at least three) on the back of the hand, which is inconvenient to operate. After the injection is completed, each adhesive tape or dressing needs to be lifted one by one before the needle can be removed. However, during this process, if the needle shakes due to improper operation, it may cause damage to the surrounding tissues, causing bleeding or nodules at the injection site to the patient. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned problems, the utility model provides an intravenous injection patch which can be fixed on an intravenous injection needle and can also be released from the intravenous injection needle, so that the needle can be quickly and conveniently fixed to the injection site such as the back of the hand, and the needle can be directly pulled out from there after the injection is completed, without causing any harm to the patient.

[0034] Furthermore, in order to provide a concise description of the exemplary embodiments, not all features of the actual embodiments (i.e., those features that are not relevant to the currently considered best mode for carrying out the present invention, or those features that are not relevant to the implementation of the present invention) may be described. Moreover, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0035] Please refer to Figure 1-Figure 4 , is a schematic diagram of the structure of an intravenous injection patch provided in an embodiment of the utility model, wherein the intravenous injection patch includes a first patch 1, a second patch 2 and a fixing member 3.

[0036] Please refer to Figure 1-Figure 3 The first patch 1 and the second patch 2 are connected to each other, and the second patch 2 can be folded along the first edge of the first patch 1. The first patch 1 is provided with a fixing hole 11.

[0037] Please refer to Figure 3 and Figure 4The fixing member 3 includes a connecting portion 31 and a clamping portion 32. The cross-sectional dimension of the connecting portion 31 is smaller than the cross-sectional dimension of the fixing hole 11, and the cross-sectional dimension of the clamping portion 32 is larger than the cross-sectional dimension of the fixing hole 11; one end of the connecting portion 31 is fixedly connected to the intravenous needle 4, and when the other end passes through the fixing hole 11 and is fixedly connected to the clamping portion 32, the clamping portion 32 abuts against the first surface of the first patch 1, and the first patch 1 is fixed on the intravenous needle 4; when the connecting portion 31 is disconnected from the intravenous needle 4, the first patch 1 is detached from the intravenous needle 4.

[0038] The intravenous injection patch of this embodiment has a first state in which the first patch 1 is fixed on the intravenous injection needle 4 and the second patch 2 is folded and raised (eg, Figure 1 and the first patch 1 is fixed on the intravenous needle 4, and the first patch 1 and the second patch 2 are both adhered to the second state around the injection site (as shown); Figure 2 and the first patch 1 and the second patch 2 are both adhered to the injection site around, the first patch 1 out of the intravenous needle 4 of the third state.

[0039] In this embodiment, Figure 5 As shown, the intravenous injection needle 4 in this embodiment includes a needle 41, a needle seat tube 42 connected to the needle 41, and an infusion tube 43 connected to the needle seat tube 42; in specific implementation, in order to prevent the first patch 1 from blocking the needle 41 and affecting the use of the intravenous injection needle 4, as shown in FIG. Figure 4 As shown, the second patch 2 can be arranged corresponding to the needle 41, and the first patch 1 can be arranged corresponding to the needle seat tube 42. At this time, based on the fact that the second patch 2 can be folded, when the acupuncture action is performed, the second patch 2 can be folded and pressed on the first patch 1, so that the needle 41 is completely exposed.

[0040] In addition, based on the description of the first state, the second state and the third state of the intravenous injection patch, those skilled in the art should understand that the first side of the first patch 1 is the side perpendicular to the extension direction of the intravenous injection needle 4 and is the side close to the needle head 41 of the intravenous injection needle 4. In addition, based on the third state, the intravenous injection needle 4 needs to be separated from the first patch 1, so the adhesive layers on the first patch 1 and the second patch 2 need to avoid the location of the intravenous injection needle 4; and based on the fact that after the intravenous injection needle 4 is inserted into the injection position, the distance between the first patch 1 and the injection position is small, in order to facilitate the removal of the release paper on the needle layer of the first patch 1 and the second patch 2, the release paper on the first patch 1 and the release paper on the second patch 2 can be provided with a side wing extending outwards respectively.

[0041] In this embodiment, when pasting the second patch 2, an alcohol cotton pad can be placed at the puncture site in advance, and then the alcohol cotton pad can be fixed to the puncture site by pasting the second patch 2 to disinfect and stop bleeding after the needle is removed. Figure 1 As shown, a hemostatic pad 21 is provided in the middle of the second surface of the second patch 2, and when the second patch 2 is pasted on the injection position, the hemostatic pad 21 is located at the injection position; specifically, by setting the size of the hemostatic pad 21 to be larger (for example, the diameter of the hemostatic pad 21 can be set between 1.5cm and 2.5cm), and setting the position of the hemostatic pad 21 in accordance with the penetration length during conventional acupuncture, it can be ensured that the hemostatic pad 21 can be located at the injection position when the second patch 2 is pasted on the injection position.

[0042] In this embodiment, the substrate of the first patch 1 and the second patch 2 (that is, the layer structure where the first surface is located, and the adhesive layer is arranged on this layer structure) can be PP, PETG or other materials with high strength and appropriate hardness.

[0043] In this embodiment, the fixing member 3 can be Figure 2 The one shown in the figure (at this time, based on the close fit between the first patch 1 and the second patch 2, and the fixation of the fixing member 3, the intravenous needle 4 can also be firmly fixed to the injection site); and in order to improve the fixing effect of the intravenous needle 4, it can also be set to two (at this time, the corresponding fixing holes 11 on the first patch 1 are also two).

[0044] In this embodiment, the material of the fixing part 3 can be a mixed material of PP and PETG, or other materials with relatively high hardness (relative to the base materials of the first patch 1 and the second patch 2); in order to ensure that the connecting part 31 in the fixing part 3 is easy to disconnect, the diameter of the connecting part 31 in this embodiment is about 1 mm.

[0045] In summary, the intravenous injection patch in this embodiment is provided with a connecting portion 31 with a smaller cross-section by setting the fixing member 3 therein, so that the connecting portion 31 can not only fix the first patch 1 on the intravenous injection needle 4 through the fixing portion 32 when being fixed on the intravenous injection needle 4, but also fix the first patch 1 on the intravenous injection needle 4, so that the first patch 1 and the second patch 2 can reach the injection position together with the needle-piercing action (based on the fact that the second patch 2 can be folded along the first patch 1, the second patch 2 can be pressed on the first patch 1 without blocking the needle 41), and then after the needle-piercing is completed, the first patch 1 and the second patch 2 can be directly pasted on the injection position (especially the second patch 2 can be directly pasted on the needle insertion site after being folded) to achieve the fixation of the needle 41 and the infusion tube 43, which is convenient and quick; the connecting portion 31 can also be easily twisted off or cut off, so that the intravenous injection needle 4 can be detached from the first patch 1, and the needle removal operation can be directly performed without lifting the first patch 1 and the second patch 2, thereby preventing damage to the patient's injection site; it is highly practical.

[0046] In an optional embodiment, in order to improve the conformity of the first patch 1 when it is attached to the patient's injection site, and further improve the stability of the first patch 1 for fixing the intravenous injection needle 4, the possibility of disturbing the intravenous injection needle 4 when twisting off or cutting off the connecting portion 31 in the fixing member 3 is reduced, thereby further reducing the possibility of causing damage to the patient's injection site. Figure 2 and Figure 4 As shown, the second surface of the first patch 1 (the surface of the first patch 1 close to the intravenous needle 4) can be provided with a first avoidance groove 12, and the first avoidance groove 12 is arranged corresponding to the intravenous needle 4. When the first patch 1 is fixed on the intravenous needle 4, part of the intravenous needle 4 is embedded in the first avoidance groove 12; at this time, the adhesive layer arranged on the second surface of the first patch 1 can be arranged to cover all other areas except the first avoidance groove 12.

[0047] In an optional embodiment, in order to improve the compliance of the second patch 2 when it is attached to the injection site of the patient, as shown in 1 and Figure 4 As shown, the second surface of the second patch 2 may be further provided with a second avoidance groove 22, the second avoidance groove 22 is arranged corresponding to the needle 41, and the second avoidance groove 22 is arranged between the hemostatic pad 21 and the first patch 1; based on the fact that the needle 41 on the other side of the hemostatic pad 21 has been inserted into the patient's blood vessel before the second patch 2 is pasted, the second avoidance groove 22 does not need to extend to the other side of the hemostatic pad 21 (that is, the side away from the first patch 1).

[0048] In an optional embodiment, in order to facilitate the operator to hold the patch for the injection, at least one reinforcing rib may be provided in the first patch 1, and when the first patch 1 is fixed on the intravenous needle 4, the extending direction of the reinforcing rib is perpendicular to the extending direction of the needle head 41 of the intravenous needle 4. Specifically, when there are two or more reinforcing ribs, the two or more reinforcing ribs are arranged at intervals, and the number of reinforcing ribs is set so as not to substantially affect the adhesive effect of the first patch 1 (the strength of the reinforcing ribs is relatively high, which will affect the adhesiveness of the first patch 1 to a certain extent).

[0049] 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.
