Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a blood transfusion and infusion venting box. Background Technology

[0002] During intravenous infusion or blood transfusion, in order to prevent air or air bubbles from entering the blood vessels, a drip chamber is used to prevent air bubbles from entering the blood vessels and causing harm to the body. However, air can also accumulate inside the drip chamber during the infusion or blood transfusion process. When too much air accumulates inside, the infusion or blood transfusion process needs to be stopped, and medical staff need to manually remove the air from the drip chamber before the infusion or blood transfusion can be resumed.

[0003] Manually purging air from the drip chamber during a pause infusion or blood transfusion not only reduces the efficiency of the infusion or blood transfusion but also increases the risk of other unexpected events during the pause. Utility Model Content

[0004] (I) Technical problems to be solved

[0005] The technical problem this invention aims to solve is that the current method of infusion and blood transfusion using a drip chamber for venting air may require medical staff to pause the infusion process to vent air, which can increase medical risks and reduce the efficiency of infusion and blood transfusion.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a blood transfusion and infusion venting box, including an inlet and an outlet for input and output, and further comprising:

[0008] The central component includes a central frame and a baffle plate. The liquid inlet and the liquid outlet are respectively located at the upper and lower ends of the central frame. Several baffle plates are arranged sequentially above and below the central frame and are fixedly installed inside the central frame to prolong the time that the liquid flows in the inner cavity of the central frame.

[0009] The spoiler is divided into an inclined part and a vertical part, which are integrally formed. The middle frame has through holes on the side wall of the corresponding vertical part, and a waterproof and breathable membrane that cooperates with the liquid is provided in the through holes.

[0010] Side shell; including a square shell plate and triangular shells integrally formed on both sides of the square shell plate. The side shell is provided with two shells respectively placed on both sides of the middle frame. The square shell plate and the triangular shell are fitted together and installed on the side of the middle frame.

[0011] As an improvement, at least one insert rod is fixedly connected to the square shell plate, with the insert rods evenly distributed. The middle frame has several connecting holes that mate with the insert rods, and the insert rods are connected to the connecting holes by bolt threads. An inner panel that mates with the inside of the middle frame is integrally formed on the square shell plate. The inner panel contains a heating element and a heat-conducting plate placed between the heating element and the inner cavity of the middle frame. The heat-conducting plate is used to transfer the heat generated by the heating element. A transparent adhesive strip that mates with the middle frame is provided around the inner panel on the square shell plate. After the square shell plate is installed, the transparent adhesive strip is located at the joint between the square shell plate and the middle frame.

[0012] As an improvement, the waterproof and breathable membrane is a PTFE film, and the top wall of the middle frame is provided with oppositely arranged EVA films.

[0013] (III) Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. After the liquid is introduced through the inlet, it will flow along the inclined baffle. The inclined baffle can prolong the time that the liquid flows in the central component, which can help to expel air bubbles in the liquid. The air can be discharged through the EVA film and the waterproof and breathable membrane.

[0016] 2. When the liquid passes through the vertical position of the spoiler, the liquid can drip slowly at this point because the gap between the vertical spoiler and the inner wall of the middle frame is small. During the dripping process, the air in the liquid can pass through the waterproof and breathable membrane and be discharged into the middle frame. In this way, the liquid can undergo multiple turbulence and air discharge, and the air will not accumulate in the middle frame. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a blood transfusion and infusion venting box includes an inlet 10 and an outlet 11 for input and output, and further includes: a central assembly; including a central frame 1 and baffles 7, the inlet 10 and outlet 11 are respectively disposed at the upper and lower ends of the central frame 1, and several baffles 7 are arranged sequentially above and below and fixedly disposed within the central frame 1 to prolong the flow time of the liquid in the inner cavity of the central frame 1; and a side shell 2; including a square shell plate 3 and triangular shells 6 integrally formed on both sides of the square shell plate 3, the side shell 2 having two respectively disposed on both sides of the central frame 1, and the square shell plate 3 and the triangular shells 6 being fitted together and installed on the side of the central frame 1.

[0027] With the above structure, the flow time of liquid inside the middle frame 1 can be extended by using the baffle 7. The specific structure for achieving venting is as follows:

[0028] like Figure 3 , Figure 4 and Figure 5As shown, the spoiler 7 is divided into an inclined part and a vertical part, which are integrally formed. The middle frame 1 has through holes on the side walls of the corresponding vertical part, and a waterproof and breathable membrane 8 that cooperates with the liquid is provided in the through holes. The waterproof and breathable membrane 8 is a PTFE film. The top wall of the middle frame 1 is provided with EVA films 9 arranged opposite to each other to further increase the breathability. Both the EVA film 9 and the PTFE film can allow air to pass through and block liquid. At least one insert rod 5 is fixedly connected to the square shell plate 3. The insert rods 5 are evenly arranged. The middle frame 1 is provided with several connecting holes 12 that cooperate with the insert rods 5. The insert rods 5 and the connecting holes 12 are connected by bolt threads.

[0029] With the above structure, exhaust can be achieved using EVA film 9 and PTFE film. At the vertical position of the spoiler 7, the waterproof and breathable membrane 8 that is in contact with the liquid can be used for effective exhaust.

[0030] Example 2

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, an inner panel 4 is integrally formed on the square shell plate 3 to fit inside the middle frame 1. The inner panel 4 is provided with a heating component and a heat-conducting plate placed between the heating component and the inner cavity of the middle frame 1. The heat-conducting plate is used to transfer the heat generated by the heating component. A transparent adhesive strip is provided around the inner panel 4 on the square shell plate 3 to fit the middle frame 1. After the square shell plate 3 is installed, the transparent adhesive strip is located at the joint between the square shell plate 3 and the middle frame 1, and the transparent adhesive strip can play a sealing role at the joint.

[0032] With the above structure, the heat generated by the heating component is transferred to the internal space of the middle frame through the heat conduction plate, which can heat the liquid.

[0033] In practical implementation of this invention, when intravenous infusion or blood transfusion is required, two infusion tubes are connected to the inlet and outlet respectively. The liquid is input through the inlet and finally discharged through the outlet. During the process, after the liquid enters the internal space of the middle frame, it will fall on the inclined part of the baffle. The flow on the inclined part of each baffle can prolong the time it is in the internal space of the middle frame. The air inside the middle frame can be discharged through the EVA film and the waterproof and breathable membrane.

[0034] When the liquid flows to the vertical position of the baffle, the gap between the vertical baffle and the inner wall of the middle frame is small, and the liquid spends more time passing through it. During this process, the liquid is located on one side of the waterproof and breathable membrane, that is, on the side of the PTFE breathable membrane. The PTFE breathable membrane allows gas to pass through but not liquid, which can block the liquid and help the air in the liquid on one side to be discharged into the middle frame through the PTFE breathable membrane. In this way, the liquid passes through the vertical position of the baffle and the PTFE breathable membrane multiple times, which can efficiently discharge air and prevent excessive air accumulation inside the middle frame. There is no need to stop manually to vent air during the infusion process, which can avoid the medical risks caused by the interruption.
