Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a light-shielding cover. Background Technology

[0002] A microinfusion pump delivers small, precise, uniform, and continuous amounts of medication into the body. It is easy to operate, allows for timed and quantitative administration, and enables adjustments to drug concentration and delivery rate as needed to maintain an effective blood concentration. In clinical practice, medications such as nitroglycerin and sodium nitroprusside require protection from light.

[0003] Currently, the method to protect the medication in syringes from light is to wrap the syringes in black plastic bags. However, this method has the following drawbacks:

[0004] 1. Because the infusion rate is adjusted according to the patient's condition, the remaining volume cannot be calculated or visually observed, which can easily lead to delays in medication changes and affect the patient's condition; 2. The remaining volume cannot be directly observed during nursing shift handover, increasing the workload of clinical nurses; 3. If the syringe is removed at night to check the remaining volume, it will not only affect the patient's medication time and condition, but also delay the patient's rest, giving the patient a bad experience; 4. The syringe nipple cannot be covered, which can easily affect the efficacy of the medication. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a light-shielding sleeve, which effectively solves the problems of inconvenience in observing the remaining liquid and poor light-shielding effect when using black plastic bags to shield syringes from light.

[0006] The technical solution is as follows: This utility model includes two arc-shaped light-shielding plates with their arc openings facing each other along the left and right axes. The two arc-shaped light-shielding plates can form a circular ring shape. Two V-shaped plates facing each other are fixed to the front side of the two arc-shaped light-shielding plates respectively. Each pair of vertically opposite V-shaped plates is symmetrical. Each pair of vertically symmetrical V-shaped plates is hinged together by a pin along the left and right axes. A torsion spring is fitted on the pin. One free end of the torsion spring contacts the upper V-shaped plate and the other free end contacts the lower V-shaped plate. A rectangular window is opened on the upper arc-shaped light-shielding plate. An arc-shaped transparent plate is fixed to the lower side of the rectangular window. A semi-circular light-shielding plate is fixed to the left end of each of the two arc-shaped light-shielding plates. Semi-circular grooves are opened on the opposite sides of the two semi-circular light-shielding plates respectively. A circular light-shielding cloth is fixed to the right end of the two arc-shaped light-shielding plates. A through-hole is provided on the back side of the light-shielding cloth.

[0007] Compared with the prior art, this utility model has the following advantages:

[0008] This utility model has a clever structure and is easy to use. It is equipped with two sets of symmetrical V-shaped plates, an arc-shaped light-shielding plate, a semi-circular light-shielding plate, a light-shielding collar, and a light-shielding cloth. By relatively squeezing the two V-shaped plates, the two arc-shaped light-shielding plates, the two semi-circular light-shielding plates, and the two light-shielding collars are opened at the rear. The syringe is then fitted inside the arc-shaped light-shielding plate, which achieves light protection for the syringe barrel, the tip, and the connection with the connecting tube, thus improving the light-shielding effect on the drug.

[0009] The device is equipped with a rectangular window, a transparent panel, and a first black plastic sheet. After lifting the first black plastic sheet, the remaining amount of medication in the syringe can be observed through the transparent panel. The transparent panel also protects the medication from light. The device is simple to operate, easy for medical staff to use, and enhances the patient's medical experience.

[0010] A pull cord is installed to narrow the opening at the right end of the light-blocking cloth, thus blocking light from the right side of the syringe barrel and the fixing point of the micro-pump. The operation is simple, easy to disassemble, and suitable for syringes of different specifications, making it easy to promote and use. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 6The invention comprises two arc-shaped light-shielding plates 1 with their arc openings facing each other along the left and right axes. The two arc-shaped light-shielding plates 1 can form a circular ring shape. Two V-shaped plates 2 with their arc openings facing each other are fixed to the front side of the two arc-shaped light-shielding plates 1 respectively. Each pair of V-shaped plates 2 with their arc openings facing each other are symmetrical. Each pair of V-shaped plates 2 with their arc openings facing each other are hinged together by a pin with their arc openings facing each other along the left and right axes. A torsion spring 3 is fitted on the pin. One free end of the torsion spring 3 contacts the upper V-shaped plate 2 and the other free end contacts the lower V-shaped plate 2. A rectangular window 4 is opened on the upper arc-shaped light-shielding plate 1. An arc-shaped transparent plate 5 is fixed to the lower side of the rectangular window 4. Semi-circular light-shielding plates 6 are fixed to the left end of the two arc-shaped light-shielding plates 1 respectively. Semi-circular grooves are opened on the opposite sides of the two semi-circular light-shielding plates 6 respectively. A circular light-shielding cloth 7 is fixed to the right end of the two arc-shaped light-shielding plates 1. A through-hole 8 is provided on the rear side of the light-shielding cloth 7.

[0019] To facilitate observation of the amount of medicine in the syringe, the transparent plate 5 is made of amber-colored polypropylene.

[0020] To better shield the liquid medicine from light, a first black plastic sheet 9 is fixed to the upper surface of the upper arc-shaped light shield 1, which can block the rectangular window 4.

[0021] In order to facilitate the reduction of the opening on the right side of the light-shielding cloth 7 so as to better shield the right end of the syringe, a C-shaped cloth sleeve 10 is fixed to the right end of the light-shielding cloth 7. A pull rope 11 is threaded through the cloth sleeve 10. The two free ends of the pull rope 11 extend out of the two openings of the cloth sleeve 10 and are respectively fixed with buckles 12.

[0022] In order to better shield the nipple and connecting tube of the syringe from light, the left ends of the two semi-circular light shields 6 are respectively fixed with semi-circular light shielding rings 13, and the two light shielding rings 13 have openings facing each other and can form a tube.

[0023] In order to better shield the back of the syringe from light, a second black plastic sheet 14 is fixed to the inner surface of the upper arc-shaped light shield 1. The second black plastic sheet 14 hangs down to block the gap between the two arc-shaped light shields 1.

[0024] In order to shield syringes of different sizes from light, the inner diameter of the ring formed by the two arc-shaped light shields 1 is slightly larger than the outer diameter of the 50ml syringe.

[0025] The arc-shaped light-shielding plate 1, the semi-circular light-shielding plate 6, and the light-shielding collar 13 are all made of black light-shielding material.

[0026] In use, this utility model is set to an initial state where the pull rope 11 is not tightened at the right opening of the light-shielding cloth 7; when the syringe containing the drug that needs to be protected from light is installed on the micro-pump and the syringe needs to be shielded from light, the medical staff holds the V-shaped plate 2 so that the rectangular window 4 is at the top. The left index finger and thumb pinch the two V-shaped plates 2 on the left side respectively, and the right index finger and thumb pinch the two V-shaped plates 2 on the right side respectively. The two hands squeeze the V-shaped plates 2 relative to each other, so that the front ends of each pair of V-shaped plates 2 opposite each other swing relative to each other around the pin. The torsion spring 3 is compressed, and the rear sides of the two adjacent V-shaped plates 2 drive the arc-shaped light-shielding plates 1 to swing in opposite directions, so that the rear sides of the two arc-shaped light-shielding plates 1 open. At the same time, the rear sides of the semi-circular light-shielding plate 6 and the two light-shielding collars 13 also open, and the width of the notch 8 of the light-shielding cloth 7 increases.

[0027] When the opening between the two curved light shields 1 is larger than the outer diameter of the syringe, maintain the current state and move the two curved light shields 1 to gradually insert the syringe between the two curved light shields 1. Place the connection between the infusion set nipple and the connecting tube into the light shielding ring 13. During this process, the two adjacent V-shaped plates 2 will be gradually loosened until the syringe is completely inside the two curved light shields 1. Then, loosen the four V-shaped plates 2. Under the action of the torsion spring 3, the four V-shaped plates 2 keep the two curved light shields 1 covering the syringe and the light shielding ring 13 covering the nipple. Then adjust the state of the light shielding cloth 7 so that the light shielding cloth 7 blocks the right side of the syringe barrel and the fixing point of the micro-pump. Pull the two free ends of the pull rope 11 and shorten the cloth sleeve 10 so that the opening at the right end of the light shielding cloth 7 is reduced. Stop pulling the pull rope 11 and tie the two free ends of the pull rope 11 together to achieve light shielding of the syringe.

[0028] During intravenous infusion, when it is necessary to check the amount of medication in the syringe, the first black plastic sheet 9 is lifted upwards. After the medical staff observes the amount of medication in the syringe through the transparent plate 5, the first black plastic sheet 9 is covered to cover the rectangular window 4.

[0029] After the medication in the syringe is finished, untie the two free ends of the pull rope 11 and squeeze each pair of adjacent V-shaped plates 2 to open the back of the two arc-shaped light shields 1 and open the two light shielding rings 13. Then remove the two arc-shaped light shields 1 from the syringe. Alternatively, the syringe can be removed from the micro-pump first, and then the device can be removed from the syringe.

[0030] In use, the device can be installed on the syringe first, with the light-shielding cloth positioned to the right of the syringe's scale line. Then, the syringe with the device installed is fixed to the micro-pump. The clips on the micro-pump press the light-shielding cloth against the syringe, thus fixing the syringe to the micro-pump.
