Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel hemostatic powder delivery system. Background Art

[0002] In the medical device field, hemostatic powders are used not only to stop bleeding from surface wounds but also to stop bleeding from capillaries, veins, and arterioles, as well as oozing from surgical wounds, during general and gynecological surgeries when compression, bandaging, or other conventional hemostatic measures are ineffective or impossible. These hemostatic procedures typically require endoscopic intervention, making quick and easy delivery of the powder to the bleeding site a significant challenge.

[0003] Currently, the delivery of hemostatic powder to the patient's bleeding point on the market relies on an airbag to transport the hemostatic powder through a catheter to the bleeding point. The disadvantage is that the air contains polluted particles, which are harmful to the human body. In addition, the hemostatic powder will float and stick to the endoscope lens at the outlet of the flexible endoscope working channel, thereby blurring the doctor's vision and affecting the operation. In view of this, we proposed a new hemostatic powder delivery system. Utility Model Content

[0004] The purpose of the present utility model is to provide a novel hemostatic powder delivery system to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new hemostatic powder delivery system, comprising a spray pipe and a Y-shaped three-way pipe connected to the spray pipe, the spray pipe comprising an injection port, the side wall of the injection port being provided with a Luer connector connected thereto, the side wall of the injection port being also fixedly connected to a spray pipe handle, the bottom of the spray pipe handle being connected to a catheter, and the injection port, the Luer connector and the catheter being connected to each other.

[0006] Optionally, one end of the catheter away from the drug injection port is connected to one end of a flexible endoscope working channel through a biopsy valve, and the other end of the flexible endoscope working channel is provided with an endoscope working component.

[0007] Optionally, the Y-type three-way pipeline includes pipe 1 and pipe 2, pipe 1 is connected to one end of the Luer connector, and pipe 2 is connected to a biopsy valve, and the biopsy valve is assembled at the input port of the working channel of the flexible endoscope.

[0008] Optionally, the Y-shaped three-way pipeline is connected to one end of the two-way valve through a hose, and a filter is passed through and placed in the hose.

[0009] Optionally, one end of the two-way valve away from the Y-shaped three-way pipeline is connected to the carbon dioxide pump station.

[0010] Optionally, the endoscope working component includes a light source, a water and gas port, a lens, and an internal working channel output port.

[0011] Compared with the existing technology, the present invention provides a new hemostatic powder delivery system with the following beneficial effects:

[0012] This new hemostatic powder delivery system uses a Y-shaped three-way pipeline in which gas flows into the human body through a Luer connector and a catheter passing through a biopsy valve and a working forceps channel of a flexible endoscope. At this time, a hemostatic powder balloon is inserted into the injection port and squeezed to deliver the hemostatic powder to the inside of the injection port. As carbon dioxide gas is injected from the Luer connector in the spray tube, the hemostatic powder is quickly injected into the bleeding part of the patient through the catheter to achieve the purpose of hemostasis and relieve the patient's pain. In addition, the catheter of the Y-shaped three-way pipeline flows out of the working forceps outlet through the gap between the biopsy valve, the working forceps channel and the catheter, preventing the hemostatic powder from sticking to the lens, making the doctor's vision clearer and thus saving treatment time.

[0020] The end of the catheter 104 away from the injection port 101 passes through the flexible endoscope working channel 302, and the other end of the flexible endoscope working channel 302 is provided with an endoscope working component 303. The end of the injection port 101 is connected to a balloon 105.

[0021] In this embodiment, the endoscope working component 303 includes a light source 3031, a water vapor port 3032, a lens 3033, and an output port for the flexible endoscope working channel 302. This working component is used by the operator to take photos and view the bleeding site of the patient while spraying hemostatic powder. The Y-shaped three-way pipe 205 is connected to one end of the Luer connector 207 via pipe 1 2051. The other end of the Luer connector 207 is connected to the injection port 101.
