Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to an infusion light-proof cover. Background Technology

[0002] Some intravenous medications require protection from light during infusion. This means that measures must be taken to protect the medication from light during the infusion process to prevent adverse reactions such as changes in drug properties caused by direct exposure to sunlight or indoor lighting. Examples include cisplatin and nitroglycerin. When administering light-protected medications, not only is a special light-protected infusion set required, but a light-protected sleeve or bag must also be placed over the infusion bag.

[0003] Current infusion light-shielding covers still have the following drawbacks in practical use:

[0004] First, an observation port needs to be opened on the front of the infusion light-proof cover for checking the patient's personal information affixed to the corresponding position of the infusion bag, or for scanning the code. Medical staff use a handheld scanner to scan the barcode or QR code on the infusion bag. In the existing technology, the opening and covering of the observation port is generally accomplished by a flip-up single piece of cloth and Velcro attached to the cloth. However, (1) the Velcro may not stick firmly after a long time, (2) after flipping the single piece of cloth for a long time, a slight gap may appear between the side and the observation port, and (3) when the single piece of cloth is flipped open, the entire observation port, especially the oblique side, is in contact with the light, and the shielding of the observation port needs to be improved.

[0005] Secondly, due to the light-blocking material of the cover itself, its transparency is low. Medical staff cannot observe the remaining amount of medication inside the infusion bag with the naked eye. If medical staff need to remove the infusion bag from the cover or open the observation port to check the remaining amount, sunlight or indoor lighting will inevitably shine on the infusion bag during this observation process, affecting the medication inside. Moreover, removing and putting the infusion bag back or opening and then covering the observation port is time-consuming and inefficient. Currently, there is no suitable and efficient remaining amount reminder device. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an infusion light-proof sleeve to solve at least one of the above technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An infusion light-shielding sleeve includes a light-shielding sleeve body for holding an infusion bag. The top of the light-shielding sleeve body has a placement opening, and the bottom of the light-shielding sleeve body has a tube outlet. The outer surface of the light-shielding sleeve body has an observation opening. The outer surface of the light-shielding sleeve body also has a first light-shielding plate and a second light-shielding plate located to the left and right of the observation opening, respectively, to shield the observation opening. The outer surface of the light-shielding sleeve body also has a third light-shielding plate and a fourth light-shielding plate located above and below the observation opening, respectively. The third light-shielding plate and the fourth light-shielding plate have mutually compatible locking interfaces. The light-shielding sleeve body also has a remaining fluid reminder device.

[0009] Furthermore, the depth of the card interface is 3-10mm.

[0010] Furthermore, the light-shielding sleeve body has matching sealing strips on both sides for closing the placement opening.

[0011] Furthermore, the top of the light-shielding sleeve body is provided with a suspension part.

[0012] Furthermore, the remaining volume reminder device includes an elastic frame disposed within the light-proof sleeve body. The elastic frame has a receiving opening for securing the infusion bag. The elastic frame is connected to a horizontally arranged sliding piece. The light-proof sleeve body has a sliding groove arranged along its own height direction. The sliding piece is slidably connected to the sliding groove and slides up and down within the sliding groove.

[0013] Furthermore, the outer surface of the light-shielding cover body is also provided with a rigid light-shielding cover to shield the sliding groove. The rigid light-shielding cover has a scale strip on the side facing the user, and the sliding piece and the scale strip are arranged perpendicular to each other.

[0014] Furthermore, the remaining volume reminder device includes a pressure sensor located at the bottom of the light-proof sleeve body, the pressure sensor being able to abut against the infusion bag, and the remaining volume reminder device also includes a controller electrically connected to the pressure sensor, the controller being electrically connected to an alarm unit.

[0015] Furthermore, the alarm unit is an alarm light, which is located on the outer surface of the light-shielding sleeve body.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model proposes an infusion light-shielding sleeve, comprising a light-shielding sleeve body for placing an infusion bag, a placement opening at the top of the light-shielding sleeve body, an outlet at the bottom of the light-shielding sleeve body, an observation opening on the outer surface of the light-shielding sleeve body, and a first light-shielding plate and a second light-shielding plate respectively located to the left and right of the observation opening on the outer surface of the light-shielding sleeve body to shield the observation opening; a third light-shielding plate and a fourth light-shielding plate respectively located above and below the observation opening on the outer surface of the light-shielding sleeve body, the third light-shielding plate and the fourth light-shielding plate having mutually compatible locking interfaces. The combined use of the first light-shielding plate, the second light-shielding plate, the third light-shielding plate and the fourth light-shielding plate and the locking interfaces makes it less likely for gaps to appear on the side when the observation opening is shielded, and when the observation opening is opened and exposed, the surrounding area, especially the oblique side, has corresponding light-shielding plates to block light to a certain extent, thereby improving the shielding performance. Moreover, this design is simple, convenient and durable.

[0018] 2. The infusion light-proof sleeve proposed in this utility model, with the setting of the remaining liquid reminder device, allows medical staff to assess the remaining liquid in the infusion bag without having to remove the infusion bag multiple times. This is achieved by observing the position of the slider, thereby preventing the liquid from being directly exposed to sunlight or indoor lighting. This process is simple and convenient, and can also effectively reduce the workload of medical staff and improve their work efficiency. Attached Figure Description

Detailed Implementation

[0028] The following is combined with Figure 1-7 This utility model will be described in detail.

[0029] Example 1

[0030] An infusion light-shielding sleeve includes a light-shielding sleeve body 10 for holding an infusion bag. The top of the light-shielding sleeve body 10 has a placement opening 101, and the bottom of the light-shielding sleeve body 10 has an outlet 102. The outer surface of the light-shielding sleeve body 10 has an observation opening 103. The outer surface of the light-shielding sleeve body 10 also has a first light-shielding plate 201 and a second light-shielding plate 202 located to the left and right of the observation opening 103, respectively, to shield the observation opening 103. The outer surface of the light-shielding sleeve body 10 also has a third light-shielding plate 203 and a fourth light-shielding plate 204 located above and below the observation opening 103, respectively. The third light-shielding plate 203 and the fourth light-shielding plate 204 have mutually compatible locking interfaces 205. The light-shielding sleeve body 10 also has a remaining fluid reminder device.

[0031] Specifically, the shape of the light-shielding sleeve body 10 is adapted to the shape of the infusion bag, and the light-shielding sleeve body 10 is made of a light-shielding material. The specific material can be found in existing technology and common knowledge in this field. The total area of ​​the first light-shielding plate 201 and the second light-shielding plate 202 is not less than the area of ​​the observation port 103, and must be sufficient to cover the observation port 103. Similarly, the total area of ​​the third light-shielding plate 203 and the fourth light-shielding plate 204, after being interlocked, must not be less than the area of ​​the observation port 103. This utility model only studies how to protect the infusion bag from light. For light protection of other infusion components such as infusion tubing, refer to existing technology, such as using light-shielding medical PVC infusion tubing.

[0032] In this embodiment, the depth of the card interface 205 is 3-10mm.

[0033] In this embodiment, the light-shielding sleeve body 10 has matching sealing strips 104 on both sides inside for closing the placement opening 101.

[0034] In this embodiment, the top of the light-shielding sleeve body 10 is provided with a suspension part 105. The light-shielding sleeve body 10 can be hung on the infusion stand through the suspension part 105, which facilitates fixing the position of the light-shielding sleeve body 10.

[0035] In this embodiment, the remaining fluid reminder device includes an elastic frame 301 disposed within the light-proof sleeve body 10. The elastic frame 301 has a receiving opening 302 for securing the infusion bag. The elastic frame 301 is connected to a horizontally arranged sliding piece 303. The light-proof sleeve body 10 has a sliding groove 304 arranged along its own height direction. The sliding piece 303 is slidably connected to the sliding groove 304 and slides up and down within the sliding groove 304. Specifically, the elastic frame 301 is located slightly below the light-proof sleeve body 10, and the elastic frame 301 is composed of four elastic bands and an elastic ring. The elastic ring is located in the middle of the four elastic bands to form the receiving opening 302.

[0036] When the infusion bag is placed into the receiving opening 302 inside the light-proof cover body 10, the elastic frame 301 is compressed and moves downward due to the gravity of the medicine inside the infusion bag. The elastic frame 301 also drives the sliding piece 303 to slide downward in the sliding groove 304 until the elastic force generated by the deformation of the elastic frame 301 is sufficient to match the gravity of the medicine inside the infusion bag.

[0037] As the infusion bag gradually reduces its contents during the infusion process, the elastic frame 301 gradually rebounds, causing the sliding plate 303 to slide upwards within the groove 304. When assessing the remaining contents of the infusion bag, medical staff can directly judge the situation by observing the position of the sliding plate 303. When the sliding plate 303 slides to the top of the groove 304, it indicates that the infusion bag has been completely delivered, and medical staff need to proceed to the next step.

[0038] In this embodiment, the outer surface of the light-shielding sleeve body 10 is also provided with a rigid light-shielding cover 305 to shield the sliding groove 304. The rigid light-shielding cover 305 has a scale strip 306 on the side facing the user, and the sliding piece 303 is set perpendicular to the scale strip 306. Specifically, in order to prevent external light from shining into the light-shielding sleeve body 10 from the sliding groove 304, a rigid light-shielding cover 305 is provided. The rigid light-shielding cover 305 is made of a semi-transparent light-shielding material, such as polyvinyl chloride (PVC) or polyolefin elastomer (TPE). This not only blocks light but also allows the current position of the sliding piece 303 to be seen through the rigid light-shielding cover 305, achieving the dual functions of light blocking and observation. The scale on the scale strip 306 represents the remaining amount of medicine in the infusion bag. For harmony and aesthetics, the light-shielding sleeve body 10 and the rigid light-shielding cover 305 can be made of the same material.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is that:

[0041] In this embodiment, the remaining fluid reminder device includes a pressure sensor (not shown in the figure) located at the bottom of the light-proof sleeve body 10. The pressure sensor can abut against the infusion bag. The remaining fluid reminder device also includes a controller electrically connected to the pressure sensor. The controller is electrically connected to an alarm unit. Further, the alarm unit is an alarm light 401, which is located on the outer surface of the light-proof sleeve body 10.

[0042] Specifically, by preset pressure values ​​within the controller, when the amount of liquid in the infusion bag decreases, the weight of the infusion bag changes. The pressure sensor detects the weight of the infusion bag in real time. When the preset pressure value is reached, the controller will activate the alarm light 401 to alert medical staff so that they can replace the infusion bag in a timely manner. The controller can be a digital pressure sensor controller, a programmable controller, or other common controllers in existing technologies.

[0043] The second embodiment is the same as the first embodiment except for the remaining quantity reminder device.

[0044] The light-proof sleeve for intravenous infusion proposed in this utility model is used as follows:

[0045] Place the infusion bag, opening downwards, into the light-proof sleeve body 10 through the placement port 101 and place it on the storage port, aligning the opening of the infusion bag with the outlet port 102 of the light-proof sleeve body 10. Then, engage the sealing strip 104 at the placement port 101, thereby covering the infusion bag inside the light-proof sleeve body 10 and achieving light protection for the medication inside the infusion bag. The light-proof sleeve body 10 is then hung on the infusion stand via the hanging part 105, and infusion can then be performed.

[0046] When medical staff need to verify information, they can use their hands to lift the third light-shielding sheet 203 and the fourth light-shielding sheet 204 to release their interlocking state. Then, they can lift the first light-shielding sheet 201 and the second light-shielding sheet 202 to the left and right respectively, exposing the observation port 103. At this time, medical staff can verify the information of the infusion bag inside the light-shielding sleeve body 10 through the observation port 103. The lifted first light-shielding sheet 201, the second light-shielding sheet 202, the third light-shielding sheet 203 and the fourth light-shielding sheet 204 will block the light around the observation port 103, thereby preventing the light from shining on the infusion bag to a certain extent. The front of the observation port 103 is blocked by the medical staff's body.

[0047] After observation, the first light-shielding plate 201 and the second light-shielding plate 202 can be flipped back first, and then the third light-shielding plate 203 and the fourth light-shielding plate 204 can be flipped back and connected to the third light-shielding plate 203 and the fourth light-shielding plate 204 through the card interface 205; or, the first light-shielding plate 201 can be flipped back first, then the third light-shielding plate 203 and the fourth light-shielding plate 204 can be flipped back, and the second light-shielding plate 202 located in the observation port 103 can be flipped back, and the upper half of the second light-shielding plate 202 can be inserted into the third light-shielding plate 203 so that it is located between the third light-shielding plate 203 and the observation port 103, while the upper half of the second light-shielding plate 202 is located on the fourth light-shielding plate 204. After the second light-shielding plate 202 is placed in this staggered manner, the third light-shielding plate 203 and the fourth light-shielding plate 204 can be connected to the third light-shielding plate 203 and the fourth light-shielding plate 204 through the card interface 205.

[0048] After placing the infusion bag inside the light-proof sleeve body 10, the infusion bag is then connected with an infusion tube. This step is specifically described in the prior art and will not be elaborated here.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
