Detailed Description

In order to enable those skilled in the art to better understand the present utility model, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1-5, a non-return structure comprises a housing 1, a sealing plug 2 connected with one end of the housing 1, an air charging component 3 connected with the other end of the housing, an air inlet channel 21 arranged in the sealing plug 2, a non-return component 4 arranged on the air inlet channel 21, an indication component 5 arranged on the non-return component 4 and capable of preventing air from flowing from the inside to the outside of the air charging component 3, and a prompt provided by the indication component 5 when the air is charged or is charged. The non-return structure of the utility model can ensure that the gas can only flow into the inflatable part 3 in the forward direction and can not flow out of the inflatable part in the reverse direction, and the indication part 5 is arranged on the sealing plug 2, and the indication part 5 can clearly indicate whether the gas is in the inflow state. The non-return structure of the present utility model is suitable for an arterial compression hemostat, and since the arterial compression hemostat is used for a femoral artery interventional operation, medical staff needs to compress and stop bleeding on the affected part of a patient, and the balloon 31 of the inflation component 3 needs to be inflated to a proper procedure. The medical staff can control whether to stop the inflation by observing the size of the balloon 31, and the non-return structure of the utility model specifically indicates the component 5, so that the inflation suitability of the non-return structure can be further ensured.

Specifically, the non-return part 4 includes a connecting post 41, a movable rod 42, a compression spring 43, and a push rod cap 44; the intake passage 21 is provided with a support member 22, and the movable rod 42 is movable on the support member 22. The indicating member 5 comprises a dome 51 and a protrusion 52, the dome 51 being arranged on the inner wall of the sealing plug 2, the protrusion 52 being arranged on the push rod cap 44, the dome 51 being able to cooperate with the protrusion 52, i.e. the dome being able to give off a warning sound when the dome 51 is in contact with the protrusion 52. In the initial state, the elastic piece 51 is located at the lower part of the protrusion 52, when the air inlet channel 21 is inflated, the push rod cap 44 is extruded by the external air, so that the push rod cap moves downwards, and at this time, the thickness of one side of the elastic piece 52 close to the sealing plug is larger than that of one side of the elastic piece far away from the sealing plug, so that the protrusion 52 can stir the elastic piece 52, and the elastic piece can give out a prompt tone to prompt that the air is inflated. In addition, during the filling process, since the visual window 23 is provided on the sealing plug 2, the elastic sheet is provided on the visual window, and the movement of the protrusion 52 is visualized, the position of the elastic sheet 51 can be regarded as a standard scale mark, when the protrusion 52 is far away from the elastic sheet 51, it can be regarded as that the gas inside the inflatable member 3 is less, and when the protrusion 52 starts to approach the elastic sheet 51, it can be regarded as that the gas inside the inflatable member 3 has started to increase, and attention is required. Whether the external air is required to be removed or not, or the experience of medical staff is relied on to judge the proper degree of the air filling. The size of the balloon 31, the protrusion 52 and the distance from the elastic sheet 51 are all the judging criteria for judging whether to inflate properly. Of course, when the external air is removed, the push rod cap 44 is also reset, and at this time, the elastic sheet 51 can be contacted with the protrusion 52, and the elastic sheet 51 can give out a prompt tone to prompt the end of inflation.

The non-return element 4 mainly effects the opening or closing of the air inlet 24 against the movable rod 42 and the compression spring 43. Specifically, the movable rod 42 includes a cross bar 421 and a straight bar 422, the compression spring 43 is sleeved on the movable rod 42, one end of the compression spring 43 abuts against the cross bar 421, and the other end abuts against the connecting column 41; the support is provided with an air inlet 24, a straight rod 422 can move in the air inlet, a push rod cap 44 is positioned at the end of the straight rod 422 and on one side of the support 22, and a cross rod 421 is positioned on the other side of the support 22; when the cross bar 421 abuts the support 22, the air inlet 24 can be sealed. In a simple manner, in the initial state, the cross bar 421 abuts against the support 22, the cross bar 421 is provided with a sealing layer, which seals the air inlet 24, when the external air is filled into the air inlet channel of the sealing plug, the compression spring 43 is pressed, and the movable rod 42 moves downwards, the cross bar 421 is away from the air inlet 24, and the external air can enter the air inlet channel 21 of the sealing plug from the air inlet 24, thereby entering the inflatable member 3. The inflatable member 3 includes a balloon 31 and a balloon tube 32, one end of the balloon tube 32 is connected to the balloon 31, and the other end is connected to the housing 1, so that gas can flow from the housing 1 into the balloon 31. With the increase of the gas in the balloon 31, the pressure of the gas in the balloon 31 is increased, the movable rod 42 can be pushed outwards, and when the gas is completely withdrawn, the movable rod 42 can be reset under the action of the pressure spring 43, that is, the gas inlet 24 is blocked, and the gas in the inflatable part is blocked.

It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model.
