Description

Technical Field

[0001] The utility model relates to the technical field of blood pressure instruments, in particular to a rubber airway tube used for blood pressure instruments. Background Art

[0002] A sphygmomanometer is an instrument for measuring blood pressure, also known as a blood pressure monitor. Sphygmomanometers mainly include auscultatory sphygmomanometers and oscillometric sphygmomanometers. Auscultatory sphygmomanometers mainly include: mercury sphygmomanometer, spring gauge sphygmomanometer, light display sphygmomanometer, liquid crystal sphygmomanometer, etc. The oscillometric method is also called the oscillation method. Its principle is to obtain the oscillation wave generated during the deflation process and convert it into the blood pressure value through a certain algorithm. Most electronic sphygmomanometers are designed using the oscillometric principle.

[0003] The rubber hose used in existing blood pressure monitors is made of rubber, and will be deformed and broken due to bending during long-term use. In this way, the rubber airway will leak gas through the broken part during the gas transmission process, resulting in the inability to effectively deliver the gas in the pressurized airbag into the cuff, thereby affecting the blood pressure data measured by the blood pressure monitor. In addition, the staff cannot observe the tiny cracks on the rubber hose with the naked eye, and will inform the patient of the wrong measurement data. Utility Model Content

[0004] The utility model aims to solve the above problems and provides a rubber airway for a blood pressure monitor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rubber airway for a blood pressure monitor comprises a rubber hose, a movable collar is mounted on the rubber hose, a through slot is provided on one side of the collar, a support block is fixedly connected to the inner wall of the through slot, a film fixing ring is fixedly connected to the inner wall of the support block, a film is fixedly connected to the outer wall of the film fixing ring, an extension slot is provided on one side of the support block, and the collar is fixed to the rubber hose by a fastener.

[0007] Preferably, the fastener includes an arc-shaped sealing block 1, one side of which is fixedly connected to a support shaft, an arc-shaped sealing block 2 is hingedly connected to the outer wall of the support shaft, one side of the arc-shaped sealing block 1 is fixedly connected to a clamping block, one side of the arc-shaped sealing block 2 is fixedly connected to a clamping column, and the clamping column and the clamping block are connected by a limit piece.

[0009] Preferably, a side ear is fixedly connected to one side of the clamping plate.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] In the present application, the staff first puts two rings on the two ends of the rubber hose, and then tightens the film on the film fixing ring so that the film covers the entire outer wall of the rubber hose, then grasps the side ear and rotates the clamping plate through the torsion spring shaft, and then rotates the arc sealing block 2, so that the arc sealing block 1 and the arc sealing block 2 clamp and fix the outer wall of the rubber hose. At this time, the clamping column will be inserted into the arc groove, and the staff will loosen the side ear, and the clamping plate will be pushed by the torsion spring shaft to limit the clamping column, so that the ring is fixed on the rubber hose. When the rubber hose ruptures, the leaked gas will cause the film to expand, so that the staff can intuitively understand the rupture of the rubber hose. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] Embodiment 1:

[0021] like Figure 1-4 As shown, a rubber airway for a blood pressure monitor comprises a rubber hose 1, on which a movable collar 2 is mounted, the number of collars 2 being two and the two collars 2 being mounted at different ends of the rubber hose 1 respectively, a through slot 3 being provided on one side of the collar 2, the through slot 3 being annularly arranged, a support block 4 being fixedly connected to the inner wall of the through slot 3, the support block 4 being used to fix a film fixing ring 5, a film 16 being fixedly connected to the outer wall of the film fixing ring 5, the two ends of the film 16 being fixed inside the collar 2, the inner wall of the support block 4 being fixedly connected to the film fixing ring 5, an extension groove 9 being provided on one side of the support block 4, the extension groove 9 allowing the film to extend from the groove through the support block 4, thereby making the film 16 of the film fixing ring 5 annularly sleeved on the outer wall of the rubber hose 1 to improve the sealing performance of the film 16, and the collar 2 being fixed to the rubber hose 1 by a fastener.

[0022] Embodiment 2:

[0023] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the fastener includes an arc-shaped sealing block 6, which is fixedly installed on one side of the collar 2, and a support shaft 7 is fixedly connected to one side of the arc-shaped sealing block 6. An arc-shaped sealing block 2 8 is hinged on the outer wall of the support shaft 7. After the arc-shaped sealing block 2 8 and the arc-shaped sealing block 6 abut against each other, the collar 2 can be fixed to the outer wall of the rubber hose 1 in a circle. A clamping block 10 is fixedly connected to one side of the arc-shaped sealing block 6, and a clamping column 11 is fixedly connected to one side of the arc-shaped sealing block 2 8. The clamping column 11 is connected to the clamping block 10 through a limiter.

[0024] Embodiment three:

[0025] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the limit member includes an arc groove 12, which is opened on one side of the clamping block 10, and the rotation center of the arc groove 12 and the clamping column 11 are concentric circles. A torsion spring shaft 13 is installed on one side of the clamping block 10, and a clamping plate 14 is installed on the torsion spring shaft 13. The shape of the clamping plate 14 is set to be L-shaped, and a side ear 15 is fixedly connected to one side of the clamping plate 14. The staff can rotate the clamping plate 14 by pressing the side ear 15.

[0026] In summary, the staff first inserts one end of the rubber hose into the two collars 2, then moves one of the collars 2 so that the two collars 2 are located at the two ends of the rubber hose 1, and at the same time, the film 16 installed on the film fixing ring 5 can be tightened when the collar 2 is moved, so that the film 16 can cover the entire rubber hose 1, and then the staff presses the side ear 15 to rotate the clamping plate 14 through the torsion spring shaft 13, and the receiving staff rotates the arc-shaped sealing block 2 8. After rotating to a certain extent, the arc-shaped sealing block 2 8 will be against the arc-shaped sealing block 1 6. Then, at the same time, the clamping column 11 will be inserted into the interior of the arc groove 12, and then the staff will release the hand pressing the side ear 15, and the clamping plate 14 will be pushed to reset by the torsion spring shaft 13, and the clamping plate 14 will cover the arc groove 12 to limit the clamping column 11, so that the ring 2 will be fixed on the rubber hose 1, and the film 16 will also be covered by the rubber hose 1. When the rubber hose 1 ruptures and leaks, the gas will be trapped inside the film 16, and the film 16 will expand and become larger, so that the staff can intuitively understand that the rubber hose 1 is ruptured.
