Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a blood transfusion bag that prevents it from falling off. Background Technology

[0002] In clinical blood transfusion therapy, the stable suspension of blood bags is a key factor in ensuring the smooth conduct of the transfusion procedure.

[0003] Traditional blood transfusion bag installation typically relies on pre-drilled holes on the top of the bag for direct attachment or hanging on hooks in a transfusion stand for fixation. This traditional suspension structure has significant drawbacks: firstly, the connection between the bag's hanging holes and the hooks is often a simple snap-fit, lacking effective limiting or locking mechanisms. During clinical procedures, the bag is highly susceptible to detaching from the hooks when medical staff move around, patients turn over, or the blood volume decreases causing a shift in the center of gravity. Secondly, the contact area between the hooks and hanging holes is small, leading to instability such as swaying and rotation after hanging. This can not only loosen the transfusion line connections, affecting the stability of the transfusion rate, but also potentially cause blood stratification due to swaying, negatively impacting transfusion quality. Therefore, we propose an anti-detachment blood transfusion bag to address these issues. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A blood transfusion bag designed to prevent detachment includes: a blood transfusion bag body, wherein a drug administration line, a main infusion line, and a saline flushing line are sequentially connected from one side to the other at the bottom of the blood transfusion bag body; an extension strap is connected to the middle of the top of the blood transfusion bag body, and the surface of the extension strap has hanging holes; a base strap is provided in the middle of the back of the blood transfusion bag body, and a restraining strap is provided between the middle of the base strap and the blood transfusion bag body; the restraining strap is fitted onto the surface of the blood transfusion stand upright; a weak adhesive is applied to both sides of the outer surface of the base strap on both sides of the restraining strap, and release paper is adhered to the outer surface of the weak adhesive.

[0005] Furthermore, the hanging holes are evenly distributed along the length of the extension strip, and the number of them is greater than or equal to three.

[0006] Furthermore, one end of the restraint strap is provided with a sub-hook and loop fastener, and the other end is provided with a female hook and loop fastener that is compatible with the sub-hook and loop fastener.

[0007] Furthermore, the restraint band is an elastic band.

[0008] Furthermore, the restraint strap is slidably inserted between the middle of the base strap and the blood transfusion bag body.

[0009] Furthermore, the base tape is a thin PVC tape, and the adhesive is a polyurethane adhesive.

[0010] Furthermore, a pull strip is attached to one corner of the release paper.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model uses a triple fixation system of "hanging hole + binding strap + weak adhesive" to avoid the problem of traditional blood bags falling off due to collision, turning, and center of gravity shift. At the same time, the horizontal binding strap restricts the shaking and rotation of the blood bag, effectively preventing the blood transfusion line connection from loosening and avoiding blood leakage or air entry. It also avoids blood stratification caused by shaking, ensuring the quality of blood transfusion.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0015] This application provides an anti-drop blood transfusion bag, mainly to address the following issues in existing technologies: Firstly, the connection between the blood transfusion bag hanging hole and the blood transfusion stand hook is often a simple sleeve relationship, lacking an effective limiting or locking structure. During clinical operations, when medical staff move around and bump into the blood transfusion stand, when patients turn over, or when the blood volume in the blood transfusion bag decreases causing a shift in the center of gravity, the blood transfusion bag is very likely to fall off the hook. Secondly, the contact area between the hook and the hanging hole is small, making the blood transfusion bag prone to swaying and rotation after hanging. This can not only loosen the connection of the transfusion line, affecting the stability of the transfusion rate, but also potentially cause blood stratification due to swaying, potentially impacting the quality of the transfusion. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation: A blood transfusion bag designed to prevent detachment includes: a blood transfusion bag body 1, with a drug delivery line, a main infusion line 102, and a saline flushing line 103 sequentially connected from one side to the other at the bottom of the blood transfusion bag body 1; an extension strap 2 connected to the middle of the top of the blood transfusion bag body 1; a hanging hole 201 on the surface of the extension strap 2; a base strap 3 in the middle of the back of the blood transfusion bag body 1; a restraining strap 4 between the middle of the base strap 3 and the blood transfusion bag body 1; the restraining strap 4 is fitted onto the surface of the blood transfusion stand upright; a sub-hook and loop fastener 7 is provided at one end of the restraining strap 4, and a female hook and loop fastener 8 adapted to the sub-hook and loop fastener 7 is provided at the other end; a weak adhesive 5 is applied to the outer surface of the base strap 3 on both sides of the restraining strap 4; and release paper 6 is adhered to the outer surface of the weak adhesive 5.

[0016] Workflow Description Initial suspension and positioning: Medical staff first confirm the position of the blood transfusion stand hook, and then suspend the extension strap 2 with the hanging hole 201 on the blood transfusion stand hook to complete the initial suspension of the blood transfusion bag. At this time, the blood transfusion bag can maintain a basic suspension posture. Secondary binding and fixation: Wrap the binding strap 4 around the outside of the blood transfusion stand upright, so that the male Velcro 7 at the end of the binding strap 4 is precisely attached to the female Velcro 8 at the other end. The binding strap 4 is tightened and fixed to the surface of the upright by the adhesive force of the Velcro. At this time, the blood transfusion bag is restricted from shaking in the horizontal direction, avoiding rotation caused by collision or center of gravity shift. Assisted reinforcement and finishing touches: Locate the release paper 6 on the outer surface of the weak adhesive 5 on both sides of the base band 3, gently peel off the release paper 6 to expose the weak adhesive 5, then press the weak adhesive 5 on both sides of the base band 3 against the surface of the blood transfusion stand pole. Use the adhesiveness of the weak adhesive 5 to achieve auxiliary fixation between the base band 3 and the pole, further enhancing the vertical stability, and finally completing the anti-drop installation of the entire blood transfusion bag.

[0017] This device uses a triple fixation system of "hanging hole 201 + restraint strap 4 + weak adhesive 5" to avoid the problem of traditional blood bags falling off due to collisions, turning, and shifting center of gravity. At the same time, the horizontal restraint strap 4 restricts the shaking and rotation of the blood bag, effectively preventing the blood bag connection from loosening and avoiding blood leakage or air entry. It also prevents blood stratification caused by shaking, ensuring the quality of blood transfusion. In addition, the design of Velcro restraint strap 4 and pull strip 601 release paper 6 simplifies the fixing operation steps, and medical staff can quickly complete the installation without additional tools.

[0018] like Figure 1 As shown, in some embodiments, the hanging holes 201 are evenly distributed along the length of the extension strip 2, and the number of them is greater than or equal to three. More specifically, the hanging holes 201 are evenly distributed along the length of the extension strip 2 and the number is ≥3, which can match blood transfusion stand hooks of different heights. Medical staff can flexibly select the appropriate hanging hole 201 according to the blood volume of the blood bag, the patient's position and operation needs, avoiding the inconvenience of hanging due to the fixed height of the hook.

[0019] like Figure 4 As shown, in some embodiments, the restraint strap 4 is an elastic strap. More specifically, in clinical practice, the diameters of the infusion stand poles vary. Traditional non-elastic restraint straps 4 are prone to being too loose or too tight due to size mismatch. However, when the elastic restraint strap 4 wraps around the pole, it can automatically adjust its tightness according to the pole's thickness. For thicker poles, it can still be attached by the Velcro 8 after elastic stretching, forming an effective ring restraint force. For thinner poles, elastic contraction can prevent the restraint strap 4 from loosening, ensuring that the base strap 3 fits tightly with the pole. This adaptability eliminates the need for medical staff to replace restraint straps 4 with different specifications, simplifying the operation process. At the same time, it ensures stable horizontal positioning on various infusion stands, further improving the device's clinical versatility.

[0020] like Figure 1 As shown, in some embodiments, the restraint strap 4 is slidably inserted between the middle of the base strap 3 and the blood bag body 1. More specifically, the restraint strap 4 is slidably inserted between the middle of the base strap 3 and the blood bag body 1. This structure facilitates disassembly and reuse. During disassembly, simply unfasten the Velcro 8 and pull the restraint strap 4 out from the gap between the base strap 3 and the bag body to separate it from the blood bag. Because the restraint strap 4 is made of elastic material and the Velcro is stable, it is undamaged after separation and can be re-inserted between the base strap 3 and the bag body of a new blood bag of the same specifications, and fixed for reuse by the Velcro. This design reduces the amount of consumables per use and lowers medical costs.

[0021] like Figure 3 As shown, in some embodiments, the base band 3 is a thin PVC strip, and the weak adhesive 5 is a polyurethane adhesive. More specifically, the base band 3 is made of thin PVC strip, which has the characteristics of being thin, flexible and not easily deformed. It can fit tightly against the curved surface of the blood bag body 1 and the infusion stand pole, avoiding gaps caused by excessively hard materials that affect fixation. At the same time, the thin PVC strip is wear-resistant and anti-aging, and can withstand the tension of the restraint band 4 and the adhesion of the weak adhesive 5 for a long time, ensuring service life. The weak adhesive 5 is made of polyurethane adhesive, which has moderate and stable adhesion. It can not only be firmly bonded to the thin PVC strip, but also tightly adhere to the infusion stand pole, providing reliable auxiliary fixation force. It can also be easily peeled off without adhesive residue, without damaging the pole and the base band 3.

[0022] like Figure 3 As shown, in some embodiments, a pull strip 601 is connected to one corner of the release paper 6. More specifically, traditional release paper 6 has no auxiliary structure and often requires repeated pinching of the corner to tear it off, which is time-consuming and easily contaminates the weak adhesive 5. The pull strip 601 provides a clear point of force for removal. Medical staff only need to pinch the pull strip 601 and pull gently to quickly peel off the release paper 6.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
