Description

Technical Field

[0001] The utility model relates to the technical field of doctors' clinical practice, and particularly relates to a disposable push-type Y-shaped connector. Background Art

[0002] In view of the problems of the prior art, before the doctor clinically operates the Y-shaped connector, it is found that the inner cover is loose. Before improvement, because the inner cover is connected by screw threads, resonance during transportation will cause the inner cover and the Y-shaped main body to be loose, and the loosening will cause the hemostatic valve to fail.

[0003] The normal blood pressure range of the human body: systolic blood pressure 90 mmHg - 140 mmHg, diastolic blood pressure 60 mmHg - 90 mmHg. Because when using other Y-shaped connectors with loose inner covers clinically, the combination of the hemostatic valve silicone, the Y-shaped main body, and the inner cover thread is loose. At this time, the hemostatic function of the hemostatic valve is in a failure state, and due to the action of the pressure of the human body itself, blood keeps gushing out to the hemostatic valve and the hemostatic effect cannot be achieved. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a disposable push-type Y-shaped connector to solve the technical problem that the normal blood pressure range of the human body: systolic blood pressure 90 mmHg - 140 mmHg, diastolic blood pressure 60 mmHg - 90 mmHg. Because when using other Y-shaped connectors with loose inner covers clinically, the combination of the hemostatic valve silicone, the Y-shaped main body, and the inner cover thread is loose. At this time, the hemostatic function of the hemostatic valve is in a failure state, and due to the action of the pressure of the human body itself, blood keeps gushing out to the hemostatic valve and the hemostatic effect cannot be achieved.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A disposable push-type Y-shaped connector includes a Y-shaped connector main body. This push-type Y-shaped connector is assembled by a Y-shaped connector main body, a housing, a connecting sleeve, and a connector. A housing is provided at the bottom end of the Y-shaped connector main body, a hemostatic valve is provided at the connection between the bottom end of the Y-shaped connector main body and the housing, and a connector is provided at the top end of the Y-shaped connector main body.

[0007] As a preferred technical solution of the utility model, a hemostatic valve is provided at the bottom end of the Y-shaped connector main body, an inner cover is installed at the bottom end of the Y-shaped connector main body, the hemostatic valve is located inside the inner cover at the bottom end of the Y-shaped connector main body, and the inner cover is located inside the housing at the bottom end of the Y-shaped connector main body. When the housing is not pressed, the hemostatic valve can withstand a pressure of 3 bar (ATM) and cannot introduce instruments such as wire-through needles, and the hemostatic valve has an initial hemostatic effect.

[0008] When the outer shell is pressed, hemostatic valves can introduce medical devices such as guide wires, ensuring their passability. After passing the guide wire, when the outer shell is pulled back to the origin, the hemostatic valve still has a good hemostatic effect around the guide wire and can withstand a pressure of 3 bar.

[0009] As a preferred technical solution of the present utility model, an O-ring is provided at the top of the Y-shaped connector body, a connecting sleeve is installed at the top of the Y-shaped connector body, the O-ring is located inside the connecting sleeve at the top of the Y-shaped connector body, and the top of the joint Y-shaped connector body is located at the top of the connecting sleeve.

[0010] As a preferred technical solution of the present utility model, the joint can rotate freely and can be docked and tightened to all Luer interfaces.

[0011] As a preferred technical solution of the present utility model, the joint can lock all 6:100 Luer connectors.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the connection position between the Y-shaped main body and the inner cover is changed to a snap connection to prevent displacement. Improvement plan 2: thicken the hemostatic valve and optimize the design from a single-slit blade to an upper and lower cross-slit blade, so that when using a guide wire or a through-wire needle to pass through the hemostatic valve clinically, the hemostatic valve has better pressure resistance and airtightness. Thus, it better conforms to the assembly process, airtightness and passability, and there will be no loosening. It can perfectly solve the problem of air leakage caused by loosening in clinical practice.

[0014] The design of this Y-shaped connector is based on the concept of clinical use. The normal blood pressure range of the human body is: systolic blood pressure 90 mmHg - 140 mmHg, diastolic blood pressure 60 mmHg - 90 mmHg. Because when using other types of Y-shaped connectors with loose inner covers clinically, when the combination of the hemostatic valve silicone, the Y-shaped main body and the inner cover thread is loose, the hemostatic function of the hemostatic valve is in a failure state. Also, due to the action of the pressure inherent in the human body, blood keeps gushing out towards the hemostatic valve and the hemostatic effect cannot be achieved. Therefore, in this design, a snap connection to prevent displacement is made at the connection between the Y-shaped main body and the inner cover. The hemostatic valve is also thickened and a design of upper and lower cross-slit blades is made, so that the Y-shaped connector designed by the company has better anti-loosening performance, pressure resistance, airtightness and passability, and can perfectly solve the problems of loosening and poor pressure resistance. Through multiple simulations of clinical actual operations, it is verified that it can withstand a pressure of 3 ATM when passing a through-wire needle, and can also withstand a pressure of 3 ATM well when not passing a through-wire needle, so it can well withstand the highest pressure of 140 mmHg in the human body.

[0029] Embodiment 1

[0030] Please refer to Figure 1-7 , a technical solution provided by the present utility model: A disposable push - type Y - shaped connector, including a Y - shaped connector body 4. This push - type Y - shaped connector is assembled by a Y - shaped connector body 4, a housing 1, a connecting sleeve 7, and a connector 6. A housing 1 is provided at the bottom end of the Y - shaped connector body 4. A hemostatic valve 3 is provided at the connection between the bottom end of the Y - shaped connector body 4 and the housing 1. A connector 6 is provided at the top end of the Y - shaped connector body 4.

[0031] A hemostatic valve 3 is provided at the bottom end of the Y - shaped connector body 4. An inner cover 2 is installed at the bottom end of the Y - shaped connector body 4. The hemostatic valve 3 is located inside the inner cover 2 at the bottom end of the Y - shaped connector body, and the inner cover 2 is located inside the housing 1 at the bottom end of the Y - shaped connector body 4.

[0032] An O - ring 5 is provided at the top end of the Y - shaped connector body 4. A connecting sleeve 7 is installed at the top end of the Y - shaped connector body 4. The O - ring 5 is located inside the connecting sleeve 7 at the top end of the Y - shaped connector body 4, and the connector 6 is located at the top of the connecting sleeve 7 at the top of the Y - shaped connector body 4.

[0033] The connector 6 can rotate freely and can be docked and tightened to all Luer connectors.

[0034] The Y - shaped connector 6 can lock all 6:100 Luer connectors 6.

[0035] Specific principle description: This push-on Y-shaped connector is designed to address the clinical problem of loosening between the inner cover 2 and the main body. To this end, this design incorporates a snap-on connection at the junction of the Y-shaped main body and inner cover 2 to prevent displacement. The hemostatic valve is thickened and features upper and lower cross-cut edges, resulting in improved anti-loosening, pressure resistance, airtightness, and passability, effectively resolving loosening and poor pressure resistance issues.

[0036] Specific action description:

[0037] 1. When the housing 1 is not pressed, the hemostatic valve 3 can withstand a pressure of 3 bar (ATM) and cannot be inserted with a wire needle or other equipment. The hemostatic valve 3 has an initial hemostatic effect.

[0038] 2. When the housing 1 is pressed, the hemostatic valve 3 can be used to insert a safety needle or other device, ensuring its passability. After the safety needle has passed, when the housing 1 is pulled back to its original position, the hemostatic valve 3 still has a good hemostatic effect around the safety needle and can withstand a pressure of 3 bar.

[0039] 3. Connector 6 can lock all 6:100 Luer connectors 6.

[0040] 4. Connector 6 can rotate freely and can be docked and tightened with all Luer interfaces.

[0041] The specific technical effect is that the design of this Y-type connector is based on the concept of clinical use. The normal blood pressure range of the human body is: systolic pressure 90mmHg-140mmHg, diastolic pressure 60mmHg-90mmHg. Because when other Y-type connectors with loose inner cover 2 are used clinically, the combination of the hemostatic valve 3 silicone and the Y-type body and the inner cover 2 thread is loose. At this time, the hemostatic function of the hemostatic valve 3 is ineffective. Due to the pressure of the human body, the blood cannot be stopped and will flow out to the hemostatic valve 3, and the hemostatic effect cannot be achieved. For this reason, this design has an anti-displacement snap-on connection at the connection between the Y-type body and the inner cover 2. The hemostatic valve 3 is also thickened and has an upper and lower cross-cut design, so that the Y-type connector designed by our company has better anti-loosening, pressure resistance, airtightness and passability, which can perfectly solve the problems of loosening and poor pressure resistance. Multiple simulated clinical operations have verified that the device can withstand a pressure of 3ATM when a passwire needle is passed through, and can also withstand a pressure of 3ATM when a passwire needle is not passed through, so it can withstand the human body's maximum pressure of 140mmHg.

[0042] The specific technical effects are as follows: In response to the existing technical problems, before the doctor clinically operates the Y-shaped connector, it is found that the inner cover 2 is loose. Before the improvement, since the inner cover 2 is connected by screw threads, the resonance during transportation will cause the inner cover 2 and the Y-shaped main body to be loose, and the loosening will cause the hemostatic valve 3 to fail. Therefore, this design makes two improvement solutions to optimize this situation. Improvement solution 1: Change the connection position between the Y-shaped main body and the inner cover 2 to a non-displaceable snap connection. Improvement solution 2: Thicken the hemostatic valve 3 and optimize the design from a single-slit blade to an upper and lower cross-slit blade, so that when using a guide wire or a through-wire needle clinically to pass through the hemostatic valve 3, the hemostatic valve 3 has better pressure resistance and airtightness. Thus, it better meets the assembly process, airtightness and passability, and there will be no looseness. It can perfectly solve the problem of air leakage caused by looseness in clinical applications.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
