Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a foaming experiment connection device. Background Technology

[0002] The bubble test is a clinically common preliminary screening method for determining the presence of patent foramen ovale. It involves injecting saline containing tiny bubbles into the patient's vein and using ultrasound technology to observe the flow of these microbubbles in the heart and large blood vessels to detect the presence of right-to-left shunts at the cardiac or pulmonary circulation level.

[0003] The foaming test requires an indwelling needle inserted into the patient's left arm. The indwelling needle is connected to a T-connector; one end of the T-connector is connected to the indwelling needle, and the other two ends are connected to syringes. To perform the foaming test, the passage at one end of the indwelling needle must first be closed. Blood and air are then aspirated from the patient using a syringe and injected into another syringe through the T-connector. This process is repeated multiple times to achieve the desired foaming effect.

[0004] Currently, during foaming experiments, the repeated aspiration of two syringes poses a risk of blood splashing, which can easily cause environmental pollution and increase the occupational exposure risk for medical staff. Utility Model Content

[0005] Based on the above analysis, the present invention aims to provide a foaming experiment connection device to solve the problem that blood splashing easily occurs during foaming experiments in the prior art, causing environmental pollution and increasing the occupational exposure risk for medical personnel.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] A foaming experiment connection device includes a connecting tube assembly, connectors, a splash shield assembly, and a connecting cavity. The connecting tube assembly communicates an indwelling needle with the connecting cavity. Two connectors are also provided on the connecting cavity. The splash shield assembly is connected to the connectors.

[0008] The splash-proof assembly includes a fixed end, a shielding membrane, and a shielding end. The shielding membrane is disposed between the shielding end and the fixed end, and the fixed end is connected to the connector.

[0009] Furthermore, the connector includes a conduit and a connection port, the conduit being connected to the connecting cavity, the connection port being connected to the conduit, the connection port being able to connect a syringe to the conduit, and the fixed end being connected to the conduit.

[0010] Furthermore, a valve is provided in the catheter, and the syringe is capable of piercing the valve to enter the catheter.

[0011] Furthermore, the diameter of the connection port is larger than the diameter of the conduit, and the diameter of the fixed end is smaller than the diameter of the connection port.

[0012] Furthermore, the cross-section of the shielding film gradually increases from the fixed end to the shielding end, and the shielding end is attached to the outer wall of the syringe.

[0013] Furthermore, the shielding film is a stretchable structure film.

[0014] Furthermore, the fixed end is configured as an arc-shaped structure, and the two fixed ends cooperate with each other to form a ring.

[0015] Furthermore, a spring groove and a spring are provided on the fixed end, and the two fixed ends are connected by the spring. The spring groove is provided on the connecting end face of the two fixed ends, and the spring is provided at the bottom of the spring groove.

[0016] Furthermore, the shielding film is connected to the inner wall of the fixed end, and the shielding film has a redundancy between the two fixed ends.

[0017] Furthermore, the connecting pipe assembly includes a connecting pipe and a control component, the control component being capable of controlling the connection of the connecting pipe.

The shielding film and shielding end block the blood and control the splashing range of the blood within the anti-splash components.

[0020] (2) The foaming experiment connection device of this utility model can adjust the shielding membrane by setting the shielding membrane as a stretchable structure. When it is necessary to connect the syringe to the connection port, the shielding membrane is in a contracted state, which makes it easy to connect the syringe to the connection port. When the foaming experiment is carried out, the shielding membrane is in a stretched state, thereby blocking the blood splashed from the connection port.

[0021] (3) The foaming experiment connection device of this utility model can reduce the risk of blood splashing from the connection port during the foaming experiment by setting a valve.

[0022] (4) The foaming test connection device of this utility model, by setting a spring groove and a spring on the fixed end, makes the anti-splash component and the connection port detachably connected, so as to facilitate the selection of whether to connect the anti-splash component according to actual needs, and can connect the anti-splash component with other medical devices to prevent blood splashing.

Detailed Implementation

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0034] Example 1

[0035] A specific embodiment of this utility model discloses a foaming experiment connection device, such as... Figure 1 As shown, the device includes a connecting tube assembly 1, a connector 2, a splash guard assembly 3, and a connecting cavity 4. One end of the connecting tube assembly 1 is connected to the connecting cavity 4, and the other end is connected to an indwelling needle inserted into the patient's body. The connecting tube assembly 1 connects the indwelling needle to the connecting cavity 4. Two connectors 2 are also provided on the connecting cavity 4. The splash guard assembly 3 is connected to the connectors 2. The splash guard assembly 3 is used to prevent blood from splashing out during the foaming experiment, thereby reducing the occupational exposure risk of medical staff and preventing splashed blood from contaminating the medical environment.

[0036] The connecting tube assembly 1 includes a connecting tube 11 and a control element 12. One end of the connecting tube 11 is connected to an indwelling needle, and the other end is connected to a connecting cavity 4. Blood enters the connecting tube 11 through the indwelling needle and then enters the connecting cavity 4 through the connecting tube 11. The control element 12 is disposed on the connecting tube 11 and can control the connectivity of the connecting tube 11, thereby controlling whether blood can enter the connecting cavity 4 from the connecting tube 11. For example, the control element 12 is an infusion tube flow regulator; for example, the control element 12 is an infusion tube clamp.

[0037] like Figure 2 As shown, the connector 2 includes a conduit 21 and a connector 22. The conduit 21 is connected to the connecting cavity 4, and the connector 22 is connected to the conduit 21. The connector 22 can connect the syringe 5 to the conduit 21, and the diameter of the connector 22 is larger than the diameter of the conduit 21. Preferably, the connector 22 is a threaded interface, thereby increasing the stability of the connection between the syringe 5 and the connector 22.

[0038] Preferred, such as Figure 3 As shown, a valve 211 is provided in the catheter 21. The syringe 5 can puncture the valve 211 to enter the catheter 21. The valve 211 can reduce the risk of blood splashing from the connection port 22 during the foaming experiment.

[0039] like Figure 4 As shown, the anti-splash assembly 3 includes a fixed end 31, a shielding membrane 32, and a shielding end 33. The fixed end 31 is connected to the conduit 21. Preferably, the diameter of the fixed end 31 is smaller than the diameter of the connection port 22 to prevent the fixed end 31 from slipping off the connection port 22. The shielding membrane 32 is disposed between the shielding end 33 and the fixed end 31. The cross-section of the shielding membrane 32 gradually increases from the fixed end 31 to the shielding end 33. The diameter of the shielding end 33 matches the syringe 5 so that the shielding end 33 can adhere to the outer wall of the syringe 5. Preferably, a sealing ring 331 is provided at the contact position between the shielding end 33 and the syringe 5 to prevent blood from leaking out through the gap between the shielding end 33 and the syringe 5.

[0040] Preferably, the shielding membrane 32 is configured as a telescopic membrane, and when the syringe 5 is connected to the connection port 22, the shielding membrane 32 is in a contracted state, such as... Figure 5 As shown, this facilitates the connection between the syringe 5 and the connector 22; when conducting a foaming experiment, the shielding membrane 32 is in a stretched state, as shown. Figure 4 As shown, when blood splashes at the connection port 22, the shielding membrane 32 and the shielding end 33 block the blood splashing from the connection port 22.

[0041] Preferably, the shielding film 32 is made of a transparent material, which makes it easy to observe the connection between the connector 22 and the syringe 5 and whether there is blood splashing at the connector 22.

[0042] When using the foaming experiment connection device to conduct a foaming experiment, the shielding membrane 32 is in a contracted state. After connecting the syringe 5 to the connection port 22, the shielding membrane 32 is stretched to keep it in a stretched state, and the shielding end 33 is kept in close contact with the syringe 5. The connecting tube 11 is connected to the indwelling needle. After drawing blood from the patient through the indwelling needle, the control component 12 is adjusted to close the passage of the connecting tube 11. The foaming experiment is conducted by repeatedly drawing blood through the two syringes 5.

[0043] Understandably, if blood splashes at the connection port 22, the shielding membrane 32 and the shielding end 33 will block the blood, controlling the splash range within the anti-splash component 3, preventing the splashed blood from contaminating the medical environment, and reducing the risk of occupational exposure for medical staff.

[0044] Example 2

[0045] Another specific embodiment of this utility model is as follows: Figure 6 As shown, the difference from Embodiment 1 is that the fixed end 31 also includes a spring groove 311 and a spring 312, so that the anti-splash assembly 3 can be detachably connected to the connection port 22, making it convenient to select whether to connect the anti-splash assembly 3 according to actual needs, and to connect the anti-splash assembly 3 to other medical devices to prevent blood splashing.

[0046] The fixed end 31 is configured with an arc-shaped structure, and the two fixed ends 31 cooperate to form a ring. Preferably, the inner diameter of the ring formed by the two fixed ends 31 is the same as the outer diameter of the conduit 21 and smaller than the diameter of the connection port 22. A spring groove 311 and a spring 312 are provided on the fixed end 31. The fixed end 31 is connected by the spring 312. The spring groove 311 is provided on the connecting end face of the two fixed ends 31, and the spring 312 is provided at the bottom of the spring groove 311. One end of the spring 312 is connected to the bottom of the spring groove 311, and the other end is connected to the bottom of the spring groove 311 on the other fixed end 31.

[0047] Preferably, when the fixed ends 31 are assembled into a ring, the spring 312 is located in the spring groove 311 and is in a stretched state, so that the ring formed by the fixed ends 31 is tightly attached to the conduit 21, thus fixing the connection between the anti-splash assembly 3 and the conduit 21.

[0048] The shielding membrane 32 is connected to the inner wall of the fixed end 31. The shielding membrane 32 has a redundancy between the two fixed ends 31 so that the shielding membrane 32 can be stretched as the spring 312 is stretched.

[0049] When it is necessary to connect the fixed end 31 to the conduit 21, pull the fixed end 31 forcefully to separate the fixed ends 31 from each other. The spring 312 is further stretched under the force, so that the fixed end 31 passes through the connection port 22 and is fitted onto the conduit 21. When the force on the fixed end 31 is stopped, the spring 312 returns to its original position and drives the fixed end 31 to move, so that the two fixed ends 31 cooperate to form a ring, thereby fixing the fixed end 31 onto the conduit 21.

[0050] Compared with existing technologies, the foaming experiment connection device of this invention, by setting up an anti-splash component 3, can prevent blood splashing from the connection port 22 from contaminating the medical environment, thereby reducing the risk of occupational exposure for medical personnel. The shielding membrane 32 and the shielding end 33 block the blood, controlling the blood splash range within the anti-splash component 3. By setting the shielding membrane 32 as a telescopic structure, the shielding membrane 32 can be adjusted. When it is necessary to connect the syringe 5 to the connection port 22, the shielding membrane 32 is in a contracted state, which facilitates the connection of the syringe 5 to the connection port 22; when the foaming experiment is performed, the shielding membrane 32 is in a stretched state, thereby blocking the blood splashing from the connection port 22. By setting up a valve 211, the risk of blood splashing from the connection port 22 during the foaming experiment can be reduced. By providing a spring groove 311 and a spring 312 on the fixed end 31, the anti-splash assembly 3 can be detachably connected to the connection port 22, thereby facilitating the selection of whether to connect the anti-splash assembly 3 according to actual needs, and enabling the anti-splash assembly 3 to be connected to other medical devices to prevent blood splashing.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
