Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a light-shielding device for intravenous infusion injection sites. Background Art

[0002] During the infusion of new clinical anti-cancer drugs that require light protection, a series of light-shielding management measures must be implemented to ensure that these drugs can be safely and efficiently delivered to the patient's body, thus ensuring the patient's medication safety. Intravenous infusion catheters are commonly used medical devices for long-term placement of infusion lines in a patient's veins and can be used for the infusion of anti-cancer drugs.

[0003] Since the extension tube end of the indwelling needle is light-transmissive and has a poor light-shielding effect, it is impossible to perform light-shielded drug infusion during intravenous drip. The current clinical practice is to wrap the indwelling needle with a double layer of cotton cloth. Not only is the light-shielding effect poor, but when medical staff conduct infusion inspections, the double layer of cotton cloth covers the extension tube of the indwelling needle, making it impossible to observe the liquid medicine in the extension tube of the indwelling needle. The wrapped cotton cloth needs to be opened and re-wrapped, which is inconvenient and increases the risk of the drug being exposed to light. Utility Model Content

[0004] The purpose of the utility model is to provide a light-shielding device for intravenous infusion injection sites with good light-shielding effect and convenient observation, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0006] A light-shielding device for an intravenous infusion injection site comprises a light-shielding cloth cover and a pair of light-shielding plastic covers, wherein the two light-shielding plastic covers are respectively connected to the two ends of the light-shielding cloth cover, the light-shielding cloth cover is provided with a first incision for the entry and exit of an extension tube of an indwelling needle, and the two light-shielding plastic covers are both provided with a second incision for the entry and exit of the extension tube of the indwelling needle, and the second incisions on both sides are aligned with the positions of the first incisions.

[0007] It can be seen that compared with the traditional use of face wrapping, the light-shielding kit composed of a light-shielding cloth cover and two light-shielding plastic covers is put on the extension tube of the indwelling needle, which can better adapt to the shape of the extension tube, has a high degree of coverage and light-shielding matching, and has a better light-shielding effect. Secondly, the light-shielding cloth cover is highly soft and has the ability to bend and deform. It is connected between the two light-shielding plastic covers, so that the two light-shielding plastic covers have a high degree of freedom of movement, which is convenient for adapting to different angles and position changes of the extension tube. The length of the light-shielding cloth cover is variable, so that the overall length of the light-shielding cover formed by the light-shielding cloth cover and the light-shielding plastic cover is adjustable, so that it can be suitable for extension tubes of different models or lengths, and it has high versatility. In addition, because the light-shielding cloth cover is soft and has a variable length, the extension tube can be partially exposed by sliding the light-shielding plastic cover on one side toward the light-shielding plastic cover on the other side along the extension tube, which is convenient for medical staff to inspect and observe the circulation of the liquid medicine in the tube.

[0008] Furthermore, the two ends of the shading fabric cover are fixedly connected to the shading plastic covers on both sides by plastic connecting rings. The plastic connecting rings have a third incision aligned with the second incision for the entry and exit of the indwelling needle extension tube. Elastic metal rings are fixed on the inner walls of the two plastic connecting rings. The elastic metal rings are provided with a fourth incision for the entry and exit of the indwelling needle extension tube. The fourth incision is aligned with the third incision. When the elastic metal rings are not under force, the elastic metal rings are closed into a full circle.

[0009] When placing the indwelling needle extension tube into the light-shielding cloth cover and the light-shielding plastic cover, it is necessary to exert force to stretch the light-shielding plastic cover to expand the second incision. At the same time, the plastic connecting ring and the elastic metal ring are both stretched, and the third incision and the fourth incision are both expanded to facilitate the entry of the extension tube. At this time, the elastic metal ring elastically stores force. After the extension tube enters, the light-shielding plastic cover is loosened. Under the elastic reset action of the elastic metal ring, it automatically closes, thereby driving the plastic connecting ring and the light-shielding plastic cover to close and reset. The two end faces of the second incision are tightly attached to ensure the tightness of the light shielding.

[0010] Furthermore, the two ends of the light-shielding plastic sleeves away from each other are each provided with a cloth bundle opening, and the cloth bundle opening has a fifth incision aligned with the second incision position for the entry and exit of the indwelling needle extension tube. The diameter of the cloth bundle opening becomes smaller the further away from the light-shielding plastic sleeve.

[0011] Since there is a gap between the end of the light-shielding plastic sleeve and the extension tube, a conical fabric bundle opening is provided at the end of the light-shielding plastic sleeve to provide an auxiliary light-shielding effect, thereby preventing light from shining on the extension tube through the gap between the end of the light-shielding plastic sleeve and the extension tube, thereby further improving the light-shielding protection effect on anti-cancer drugs.

[0012] Furthermore, the shading fabric cover is provided with a mother Velcro and a child Velcro that cooperate with each other. When the mother Velcro and the child Velcro are adhered to each other, the first incision is blocked, so that the shading fabric cover is closed as a whole.

[0013] After the extension tube is placed into the shading fabric cover through the first incision, the shading fabric cover can be closed as a whole by adhering the female Velcro and the female Velcro to ensure tightness during shading.

[0014] Furthermore, the shading plastic cover and the plastic connecting ring are both made of brown transparent polyethylene material, and the shading fabric cover and the fabric drawstring are both made of non-woven fabric.

[0015] Furthermore, two pinching handles are fixed on the outer wall of each light-shielding plastic sleeve, and the two pinching handles on the same light-shielding plastic sleeve are symmetrically distributed on both sides of the second incision.

[0016] By pinching the two handles on the light-shielding plastic sleeve respectively, the light-shielding plastic sleeve can be easily pulled to drive the light-shielding plastic sleeve, the plastic connecting ring and the elastic metal ring to expand the second incision, the third incision and the fourth incision.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0018] 1. Compared with the traditional face wrapping, the utility model uses a light-shielding cloth cover and two light-shielding plastic covers to form a light-shielding kit, which is put on the extension tube of the indwelling needle. It can better adapt to the shape of the extension tube, has a high degree of coverage and light-shielding matching, and has a better light-shielding effect.

[0019] 2. The shading fabric cover in the present invention is highly flexible and has the ability to bend and deform. It is connected between the two shading plastic covers, so that the two shading plastic covers have a high degree of freedom of movement, which is convenient for adapting to different angles and position changes of the extension tube. The length of the shading fabric cover is variable, so that the overall length of the shading cover formed by the shading fabric cover and the shading plastic cover is adjustable, so that it can be applied to extension tubes of different models or lengths, and has high versatility.

[0020] 3. In the present invention, since the light-shielding fabric cover is soft and of variable length, the extension tube can be partially exposed by sliding the light-shielding plastic cover on one side toward the light-shielding plastic cover on the other side along the extension tube, making it convenient for medical staff to inspect and observe the flow of liquid medicine in the tube.

[0021] 4. The utility model provides a conical cloth bundle at the end of the light-shielding plastic sleeve to assist in light-shielding effect, thereby preventing light from shining on the extension tube through the gap between the end of the light-shielding plastic sleeve and the extension tube, thereby further improving the light-shielding protection effect of anticancer drugs.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 5 The utility model provides a light-shielding device for an intravenous infusion injection site, comprising a light-shielding cloth cover 1 and a pair of light-shielding plastic covers 2. The two light-shielding plastic covers 2 are respectively connected to the two ends of the light-shielding cloth cover 1. The light-shielding cloth cover 1 is provided with a first incision 11 for the entry and exit of the extension tube of the indwelling needle. The two light-shielding plastic covers 2 are both provided with a second incision 21 for the entry and exit of the extension tube of the indwelling needle. The second incisions 21 on both sides are aligned with the first incision 11.

[0030] When using the light-shielding device provided by the present invention to shield the extension tube of an indwelling needle from light, the indwelling needle extension tube is inserted into the light-shielding fabric cover 1 and the light-shielding plastic cover 2 through the first incision 11 and the second incision 21. The light-shielding fabric cover 1 and the two light-shielding plastic covers 2 are then placed over the indwelling needle extension tube. The light-shielding properties of the light-shielding fabric cover 1 and the light-shielding plastic covers 2 prevent the liquid medicine in the tube from being exposed to light, thereby improving the safety of anti-tumor drug infusion. Compared to traditional facial wrapping, the light-shielding fabric cover 1 and the two light-shielding plastic covers 2 form a light-shielding kit. When placed over the indwelling needle extension tube, it can better adapt to the deformation of the extension tube, provide a high degree of coverage and shading, and achieve a better light-shielding effect.

[0031] Secondly, the shading fabric cover 1 is highly flexible and has the ability to bend and deform. It is connected between the two shading plastic covers 2, so that the two shading plastic covers 2 have a high degree of freedom of movement, which is convenient for adapting to different angles and position changes of the extension tube. The length of the shading fabric cover 1 is variable, so that the overall length of the shading cover formed by the shading fabric cover 1 and the shading plastic cover 2 is adjustable, so that it can be suitable for extension tubes of different models or lengths, and has high versatility.

[0032] In addition, since the shading fabric cover 1 is soft and of variable length, the extension tube can be partially exposed by sliding the shading plastic cover 2 on one side toward the shading plastic cover 2 on the other side along the extension tube, making it convenient for medical staff to inspect and observe the flow of liquid medicine in the tube.

[0033] Specifically, the two ends of the shading cloth cover 1 are fixedly connected to the shading plastic covers 2 on both sides by plastic connecting rings 3. The plastic connecting rings 3 are provided with a third incision 31 aligned with the second incision 21 for the indwelling needle extension tube to enter and exit. An elastic metal ring 4 is fixed on the inner wall of the two plastic connecting rings 3. The elastic metal ring 4 is provided with a fourth incision 41 for the indwelling needle extension tube to enter and exit. The fourth incision 41 is aligned with the third incision 31. When the elastic metal ring 4 is not under force, the elastic metal ring 4 is closed into a full circle state. When the indwelling needle extension tube is placed in the shading cloth cover 1, the elastic metal ring 4 is closed into a full circle state. When the cloth cover 1 and the light-shielding plastic cover 2 are inside, it is necessary to exert force to stretch the light-shielding plastic cover 2 to expand the second incision 21. At the same time, the plastic connecting ring 3 and the elastic metal ring 4 are both stretched, and the third incision 31 and the fourth incision 41 are both expanded to facilitate the entry of the extension tube. At this time, the elastic metal ring 4 elastically stores force. After the extension tube enters, the light-shielding plastic cover 2 is loosened. Under the elastic reset action of the elastic metal ring 4, it automatically closes, and then drives the plastic connecting ring 3 and the light-shielding plastic cover 2 to close and reset. The two end faces of the second incision 21 are tightly attached to ensure the tightness of the light shielding.

[0034] Specifically, the ends of the two light-shielding plastic sleeves 2 that are away from each other are each provided with a cloth bundle opening 5, and the cloth bundle opening 5 has a fifth incision 51 that is aligned with the second incision 21 for the entry and exit of the indwelling needle extension tube. The diameter of the cloth bundle opening 5 becomes smaller as it moves away from the light-shielding plastic sleeve 2. Since there is a gap between the end of the light-shielding plastic sleeve 2 and the extension tube, by arranging the conical cloth bundle opening 5 at the end of the light-shielding plastic sleeve 2, an auxiliary light-shielding effect is achieved, which prevents light from irradiating the extension tube from the gap between the end of the light-shielding plastic sleeve 2 and the extension tube, thereby further improving the light-shielding protection effect of the anti-cancer drug.

[0035] Specifically, the shading fabric cover 1 is provided with a female Velcro 12 and a female Velcro 13 that cooperate with each other. When the female Velcro 12 and the female Velcro 13 are adhered to each other, the first incision 11 is blocked, so that the shading fabric cover 1 is closed as a whole. After the extension tube is placed into the shading fabric cover 1 through the first incision 11, the female Velcro 12 and the female Velcro 13 are adhered to each other, so that the shading fabric cover 1 can be closed as a whole, thereby ensuring the tightness during shading.

[0036] Specifically, the shading plastic sleeve 2 and the plastic connecting ring 3 are both made of brown polyethylene material, which has a good shading effect and a certain hardness. They are put on the extension tube and the internal center control is used to avoid squeezing the extension tube and affecting the circulation of the medicine. The shading fabric sleeve 1 and the fabric bundle 5 are both made of non-woven fabrics, which have a shading effect.

[0037] Specifically, two pinching handles 6 are fixed on the outer wall of each light-shielding plastic sleeve 2. The two pinching handles 6 on the same light-shielding plastic sleeve 2 are symmetrically distributed on both sides of the second incision 21. By pinching the two pinching handles 6 on the light-shielding plastic sleeve 2 respectively, the light-shielding plastic sleeve 2 can be easily pulled with force to drive the light-shielding plastic sleeve 2, the plastic connecting ring 3 and the elastic metal ring 4 to expand the second incision 21, the third incision 31 and the fourth incision 41.

[0038] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and the performance or use are the same, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
