Technical Field
[0001] The utility model relates to the field of medical devices, in particular to a blood transfusion set with quick connection. Background Art
[0002] At present, when a patient needs a blood transfusion, a blood transfusion tube with an insertion needle is inserted into the blood outlet tube of the blood bag (the blood outlet tube is initially sealed, and the insertion needle can be connected and communicated with the blood bag after being inserted into the blood outlet tube) to deliver the blood in the blood bag to the patient. Since the diameter of the existing insertion needle is relatively small and the tip is relatively sharp, and the diameter of the blood outlet tube on the blood bag is also relatively small, when inserting the insertion needle, the operation requirements for nurses are relatively high, and nurses need to be particularly careful and meticulous.
[0003] However, through communication and investigation with front-line clinical nurses regarding blood transfusion, it is found that most nurses have experienced the phenomenon of slow insertion of the insertion needle or blood leakage due to the insertion needle puncturing the blood bag during blood transfusion, which not only wastes blood but also poses a safety hazard to clinical blood transfusion.
[0004] Therefore, it is highly necessary to design a blood transfusion set with quick connection to solve the above technical problems. Content of the Utility Model

[0022] As Figures 1 to 4 shown, a blood transfusion set of the present utility model includes a blood bag 1 and a blood transfusion tube 2. A breakable blood passage plug body 3 is provided in the blood outlet tube 11 of the blood bag 1, and an elastic ferrule assembly 4 that can be sleeved on the blood outlet tube 11 is connected to the input end of the blood transfusion tube 2.
[0023] On this blood transfusion set, by connecting an elastic ferrule assembly 4 that can be sleeved on the blood outlet tube 11 at the input end of the blood transfusion tube 2, it is beneficial to quickly connect the blood transfusion tube 2 to the blood outlet tube 11. Additionally, a breakable blood passage plug body 3 is provided in the blood outlet tube 11 of the blood bag 1. This is beneficial for quickly connecting and communicating the blood transfusion tube 2 with the blood bag 1. This blood transfusion set enables nurses to quickly and accurately connect and communicate the blood transfusion tube with the blood bag, which can not only greatly improve the connection efficiency, but also greatly reduce the probability of blood leakage from the blood bag. This can not only avoid wasting blood, but also greatly improve the safety of clinical blood transfusion.
[0024] The breakable blood passage plug body 3 can adopt the breakable blood passage plug body in the existing blood transfusion catheter, so as to meet the normal breakable blood passage requirements and thus meet the actual use requirements.
[0025] As Figure 1 And Figure 3As shown, the elastic ferrule assembly 4 is sleeved on one end of the blood outlet tube 11 away from the blood bag 1, and the breakable blood passage plug body 3 is located on one end of the blood outlet tube 11 close to the blood bag 1. By sleeving the elastic ferrule assembly 4 on one end of the blood outlet tube 11 away from the blood bag 1 and making the breakable blood passage plug body 3 located on one end of the blood outlet tube 11 close to the blood bag 1; when the blood transfusion tube 2 is docked with the blood outlet tube 11, the breakable blood passage plug body 3 is not located inside the elastic ferrule assembly 4, which can avoid the elastic ferrule assembly 4 affecting the breaking process of the breakable blood passage plug body 3, so that the breaking operation can be conveniently carried out, which is conducive to improving the convenience and efficiency of blood transfusion operation.
[0026] As Figures 1 to 4 shown, a positioning ring groove 12 is formed on the outer circumferential surface of the blood outlet tube 11, and the elastic ferrule assembly 4 is sleeved in the positioning ring groove 12. The formation of the positioning ring groove 12 not only facilitates sleeving, but also ensures that the sleeving of the elastic ferrule assembly 4 is more stable and reliable, which helps to further improve the applicability and reliability of the blood transfusion device.
[0027] As Figures 1 to 4 shown, the elastic ferrule assembly 4 includes a sleeve tube 41, a limit sleeve 42, a spring 43, and at least two limit balls 44. At least two limit holes 45 penetrating through to its inner wall are formed on the outer wall of the sleeve tube 41, and the limit holes 45 are arranged around the axial center of the sleeve tube 41. Each limit ball 44 is respectively movably installed in each limit hole 45. The sleeve tube 41 is connected and communicated with the input end of the blood transfusion tube 2. The sleeve tube 41 is sleeved on the blood outlet tube 11. The spring 43 is sleeved on the sleeve tube 41. The limit sleeve 42 is axially slidably sleeved on the sleeve tube 41, and the spring 43 can push the limit sleeve 42 to act on each limit ball 44, so as to push a part of each limit ball 44 into the inner hole of the sleeve tube 41 through the limit sleeve 42. Such an elastic ferrule assembly 4 not only makes the operation very convenient, but also can achieve an extremely stable elastic ferrule effect, thus further improving the convenience and safety of blood transfusion.
[0028] In the actual manufacturing process, the elastic ferrule assembly 4 can also be constituted by an elastic snap ring or a plurality of elastic buckles, and other structures using elastic force to achieve sleeving can be adopted, which can meet more manufacturing and use requirements.
[0029] As Figure 4 shown, the number of the limit holes 45 is equal to the number of the limit balls 44, and the limit holes 45 are arranged in a circular array around the axial center line of the sleeve tube 41. This can not only control the processing difficulty, but also improve the stability and reliability of sleeving.
[0030] As Figures 1 to 4As shown, a sealing rubber ring 46 is arranged inside the sleeve pipe 41, and the blood outlet pipe 11 presses against the sealing rubber ring 46. This can improve the sealing performance to avoid blood leakage.
[0031] As Figure 3 shown Figure 4 in the figure, the inner hole of the sleeve pipe 41 is a stepped inner hole 410 with a large hole opening and a small hole inside. The sealing rubber ring 46 is embedded at the bottom of the large hole of the stepped inner hole 410. This can not only accurately position the sealing rubber ring 46, but also facilitate the clamping of the port of the blood outlet pipe 11 and the bottom of the large hole of the stepped inner hole 410 on the sealing rubber ring 46, which can help further improve the sealing performance and thus contribute to further improving the reliability of the blood transfusion set.
[0032] As Figure 3 shown Figure 4 in the figure, a limiting convex ring 411 is arranged on the outer circumferential surface of the sleeve pipe 41 near one end of the blood transfusion pipe 2. The limiting hole 45 is opened at one end of the sleeve pipe 41 far from the blood transfusion pipe 2. The limiting sleeve 42 includes a sleeve part 421 and a convex ring part 422. The convex ring part 422 is arranged on the inner wall of the sleeve part 421, and the inner diameter of the convex ring part 422 is smaller than the outer diameter of the limiting convex ring 411. The sleeve part 421 and the convex ring part 422 can be axially slidably sleeved on the limiting convex ring 411 and one end of the sleeve pipe 41 far from the blood transfusion pipe 2 respectively. The spring 43 is clamped between the limiting convex ring 411 and the convex ring part 422. The convex ring part 422 can push a part of the limiting ball 44 into the inner hole of the sleeve pipe 41. This can enable the spring 43 to play an elastic pressing role more stably, so that the limiting sleeve 42 can act on the limiting ball 44 more accurately and stably, and thus contribute to further improving the reliability of the blood transfusion set.
[0033] As Figure 3 shown Figure 4 in the figure, an anti - detachment convex ring 412 is arranged on the outer circumferential surface of the sleeve pipe 41. The outer diameter of the anti - detachment convex ring 412 is smaller than the inner diameter of the sleeve part 421 and larger than the inner diameter of the convex ring part 422. The convex ring part 422 and each limiting hole 45 are both located between the anti - detachment convex ring 412 and the limiting convex ring 411. The convex ring part 422 can press against the anti - detachment convex ring 412 under the action of the spring 43. At this time, the inner circumferential surface of the limiting convex ring 411 just pushes a part of the limiting ball 44 into the inner hole of the sleeve pipe 41. This can not only prevent the limiting sleeve 42 from loosening, but also enable the convex ring part 422 to limit the limiting ball 44 more accurately and stably. This can completely prevent the limiting ball 44 from detaching from the positioning ring groove 12 during blood transfusion connection, and thus can further improve the reliability and safety of the use of the blood transfusion set.
[0034] As Figure 4As shown, an annular positioning groove 413 is formed on the outer circumferential surface of the end of the sleeve pipe 41 away from the blood transfusion tube 2, and each limiting hole 45 is located between the annular positioning groove 413 and the limiting convex ring 411. A snap spring is clamped on the annular positioning groove 413, and the outer circumference of the snap spring protrudes out of the annular positioning groove 413 to form an anti - detachment convex ring 412. This can meet the normal installation requirements of the spring 43 and the limiting sleeve 42 before installing the snap spring; after installing the snap spring, it can achieve the purpose of accurately positioning the limiting sleeve 42 and preventing the limiting sleeve 42 from falling off.
[0035] As Figure 4 shown, the sleeve part 421 is axially slidably sleeved on the anti - detachment convex ring 412. An accommodation cavity 420 for accommodating part of the limiting balls 44 is formed between the inner wall of the end of the sleeve part 421 away from the blood transfusion tube 2 and the outer surface of the sleeve pipe 41, and the accommodation cavity 420 is located between the anti - detachment convex ring 412 and the convex ring part 422. Also, the thickness of the accommodation cavity 420 is less than the diameter of the limiting balls 44, and when part of the limiting balls 44 are accommodated in the accommodation cavity 420, the limiting balls 44 can completely leave the inner hole of the sleeve pipe 41. This can not only accurately limit the movement range of the limiting balls 44, but also greatly reduce the probability of the limiting balls 44 falling off, and can avoid the limiting balls 44 affecting docking and detachment, thus helping to further improve the reliability and applicability of the blood transfusion device.
[0036] As Figure 4 shown, the inner - hole diameter of the orifice of the limiting hole 45 is less than the diameter of the limiting balls 44, and the outer - hole diameter of the orifice of the limiting hole 45 is greater than the diameter of the limiting balls 44. This can not only meet the normal installation requirements of the limiting balls 44, but also more stably and accurately limit the movement range of the limiting balls 44, so that the movement of the limiting balls 44 is more accurate and stable, and further improve the applicability of the blood transfusion device.
[0037] As Figure 1 and Figure 2 shown, a drip tube 5 and a regulator 6 are provided on the blood transfusion tube 2, and a needle 7 is docked at the output end of the blood transfusion tube 2. This can better meet the actual blood transfusion requirements, thus helping to further improve the applicability of the blood transfusion device.
[0038] As Figures 1 to 4As shown in the figure, when docking is required, first move the limit sleeve 42 towards the direction close to the blood transfusion tube 2. At this time, the spring 43 is compressed, and a receiving cavity 420 is formed at the outer orifice of the limit hole 45. This can utilize the receiving cavity 420 to provide free movement space for the limit ball 44 to meet the normal socketing requirements of the socketing tube 41. Then, socket the socketing tube 41 onto the blood outlet tube 11. Next, release the limit sleeve 42, which can push the limit ball 44 into the positioning ring groove 12 under the elastic force of the spring 43 and restrict the limit ball 44 from disengaging from the positioning ring groove 12. Then, break off the blood passage plug body 3, and the blood can flow from the blood bag 1 through the blood outlet tube 11 and the socketing tube 41 into the blood transfusion tube 2 in sequence, thereby meeting the normal blood transfusion requirements. This quick-connect blood transfusion device effectively avoids the phenomenon of blood leakage caused by slow insertion of the infusion needle or blood leakage due to the infusion needle puncturing the blood bag. The operation is quick and labor-saving, greatly improving the working efficiency when multiple bags of blood need to be transfused. The connection is reliable and can effectively prevent the pipeline from falling off.
