Description

Sinus radiography device

Technical Field

The application relates to the technical field of medical instruments, in particular to a sinus radiography device.

Background

Sinus tract refers to infection and necrosis of body tissue, and is a potential blind tube which is formed after body surface is discharged from body surface and is opened on the body surface and is not communicated with internal cavity viscera, and can be formed on soft tissue, fat, muscle and even bone, etc.

Sinogram is a method of examining the position, shape, extent, shape and relationship of surrounding tissue and organs of the sinus by injecting an iodine contrast agent through a contrast catheter, preferably in an amount to fill the sinus cavity.

In clinical general sinogram, a syringe is directly connected with a tubule and inserted into a sinus orifice, and the contrast agent cannot completely enter the sinus because of sinus tortuosity or poor tightness, so that the condition of the sinus can not be fully displayed.

Therefore, the conventional sinogram contrast agent cannot completely enter the sinus, resulting in insufficient display of the sinus condition, which is a technical problem that the skilled person is urgent to solve.

The above information disclosed in the background section is only for enhancement of understanding of the background of the application and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.

Disclosure of Invention

The embodiment of the application provides a sinus radiography device to solve the technical problem that traditional sinus radiography contrast medium can not fully enter the sinus, and the sinus condition can not be fully displayed.

An embodiment of the present application provides a sinogram device, including:

an inner funnel;

a first contrast medium conduit, the lower end of which is communicated with the mouth part of the inner funnel;

a contrast agent injector;

and a second contrast medium conduit connecting the upper end of the first contrast medium conduit and the contrast medium injector.

By adopting the technical scheme, the embodiment of the application has the following technical effects:

when the sinus contrast device is used, the large end of the inner funnel is covered around the sinus orifice of a patient, and the contrast agent with pressure generated by the contrast agent injector is pushed to enter the sinus through the contrast agent second conduit, the contrast agent first conduit and the inner funnel and then through the sinus orifice. The big end of the inner funnel covers around the sinus orifice of the patient, and a relatively closed space is formed in the inner funnel, so that the pressurized contrast agent generated by pushing the contrast agent injector can only be pushed into the sinus but not flow out of the inner funnel, i.e. the contrast agent can completely enter the sinus. Therefore, the sinus contrast device can completely inject the contrast agent into the sinus, so that the sinus condition can be fully displayed.

Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of exemplary embodiments of the present application is given with reference to the accompanying drawings, and it is apparent that the described embodiments are only some of the embodiments of the present application and not exhaustive of all the embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.

Example 1

As shown in fig. 1 and 2, an sinogram device according to an embodiment of the present application includes:

an inner funnel 11;

a first contrast medium duct 21, wherein the lower end of the first contrast medium duct 21 is communicated with the mouth part of the inner funnel 11;

a contrast agent injector 23;

a second contrast medium conduit 22 connecting the upper end of the first contrast medium conduit 21 and the contrast medium injector 23.

In practice, as shown in fig. 1 and 2, the sinogram device further comprises:

an outer funnel 12 sleeved outside the inner funnel 11, wherein the upper end of the contrast agent first conduit 21 passes through the mouth of the outer funnel 12 and is fixed with the mouth of the outer funnel 12; the bottom end of the large end of the outer funnel 12 is provided with a groove 121, and the outer wall of the outer funnel is provided with a groove hole 122 communicated with the groove;

a negative pressure pump syringe (not shown);

a suction duct (not shown) connects the recess hole 122 and the suction syringe.

When using the sinus contrast device of this application embodiment, the big end shield of interior funnel is around patient's sinus orifice, and outer funnel and patient's skin contact this moment, and the negative pressure syringe takes out the air in the recess away, plays the air that takes out promptly and forms the negative pressure in the recess for outer funnel and patient's skin in close contact, played the fixed effect with outer funnel and whole sinus contrast device, make the operator of sinus contrast device after fixing sinus contrast device, the operator can be convenient carry out the operation of injecting into the sinus with the contrast agent. In this way, the operation of the sinogram device is more convenient.

Specifically, the size of the small funnel needs to be matched with the sinus ostium in design, so that the size of the small funnel is smaller. Thus, the size of the outer funnel can be set larger, and the manual operation of an operator is facilitated.

In practice, as shown in fig. 1 and 2, the notch of the groove 121 is an inverted V-shaped notch.

The notch of the inverted V-shaped structure makes the size of the groove smaller, and then makes the size of the outer funnel smaller.

As an alternative, the distance between the bottom end of the inner funnel and the bottom end of the outer funnel is 3mm or more and 6mm or less.

As an alternative, the distance between the bottom end of the inner funnel and the bottom end of the outer funnel is 5mm.

Thus, when the sinogram device is fixed on the skin of a patient through the outer funnel, the inner funnel can be in close contact with the skin around the sinus ostium of the patient, and does not excessively squeeze the skin around the sinus ostium.

In practice, as shown in fig. 1 and 2, the first contrast medium conduit 21 is a hard conduit and the second contrast medium conduit 22 is a soft conduit.

The first catheter of contrast agent adopts the hard pipe for the position between interior funnel, the first catheter of contrast agent and the outer funnel is fixed relatively, the operator of being convenient for operates sinus contrast device. The second contrast medium conduit adopts a soft conduit, can be conveniently connected with a contrast medium injector, and is also convenient for an operator to operate the sinus contrast device.

In implementation, the negative pressure pumping catheter is a soft catheter.

The negative pressure pumping catheter adopts a soft catheter, can be conveniently connected with a negative pressure pumping injector, and is also convenient for an operator to operate the sinus radiography device.
