Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a multifunctional gynecological and obstetric postoperative bleeding collection and measurement device. Background Art

[0002] The collection and measurement of bleeding after gynecological and obstetric surgery is an important part of postoperative care, especially for the monitoring of postpartum hemorrhage. The main methods of traditional bleeding collection and measurement are weighing and volume measurement. The weighing method requires the use of an absorbent pad (such as gauze or a special absorbent pad). The amount of bleeding can be estimated by calculating the weight difference between the wet pad and the dry pad and subtracting the water absorption of the pad itself (usually 1 gram of blood is absorbed per gram of absorbent). The volume measurement method requires the use of a specially designed container to collect blood, and the amount of bleeding can be measured by directly reading the scale on the container. Improving the accuracy of bleeding volume measurement can enable more effective clinical decisions for patients.

Compared with the prior art, the Chinese invention patent with publication number CN114869248A connects different drainage tubes inside the shunt frame to replace the loading block to collect blood, thereby avoiding blood leakage caused by untimely replacement of the loading block.

[0004] However, in the process of filtering blood through the sieve plate (filter) to prevent blockage, the blood clots in the blood will be filtered on the sieve plate (filter), and the blood clots filtered on the sieve plate (filter) will affect the blood passage rate, and the removal of blood clots as a component of the blood will cause a large error in the final measurement of the amount of bleeding. Therefore, there is a need for a multifunctional gynecological and obstetrical postoperative bleeding collection and measurement device that can prevent blockage and reduce the error in bleeding measurement, and can autonomously replace the collection container to avoid untimely replacement. Summary of the invention

[0035] The cutting and knocking leaves 8 are axially symmetrically arranged at the inner upper part of the collecting main pipe 4. A driving mechanism 9 for driving the movement of the cutting and knocking leaves 8 is arranged between the axially symmetrically arranged cutting and knocking leaves 8. The driving mechanism 9 includes a driving rod 901 rotatably connected to the bottom of the axially symmetrical cutting and knocking leaves 8 and a rotating groove 902 opened on the inner upper side of the collecting main pipe 4.

The sealing rotating ring 903 A vertical slide groove 912 is symmetrically provided on the outside, and a belt shaft 913 located inside the upper inclined groove 910 or the lower inclined groove 911 is slidably connected inside the vertical slide groove 912.

The symmetrical belt shaft 913 can rotate at the top of the abutment ring 914 but does not separate from the top of the abutment ring 914.

[0037] The driving mechanism 9 also includes an air pressure chamber 915 embedded between the electric telescopic rod 22 and the mounting cylinder 23, a piston block 916 is arranged inside the air pressure chamber 915, a linkage rod 917 is fixedly connected between the piston block 916 and the reciprocating frame 907, an air vent group 918 is evenly opened on the upper part of the outer part of the air pressure chamber 915, an air pressure tube 919 extending to the inner side of the collecting main pipe 4 is axially fixedly connected to the lower part of the outer part of the air pressure chamber 915, a piston rod 920 fixedly connected to the abutment ring 914 is arranged on the upper part of the inner part of the air pressure tube 919, when the reciprocating frame 907 reciprocates up and down, the linkage rod 917 can drive the piston block 916 to move up and down inside the air pressure chamber 915, so that the piston rod 920 can drive the abutment ring 914 to move reciprocatingly up and down, thereby realizing intermittent reversing of the cutting and knocking leaves 8.

[0038] The working principle of this embodiment is as follows: in order to reduce the error in measuring the amount of bleeding, the liquid anticoagulant can be introduced into the interior of the collecting chamber 1 and the collecting main pipe 4 in advance, so that the interior of the collecting chamber 1 and the collecting main pipe 4 are soaked with the liquid anticoagulant. At this time, the amount of liquid anticoagulant introduced is recorded, and then the bottom block 6 can be rotated in sequence to allow the liquid anticoagulant to be discharged through the collecting branch pipe 5. At this time, the amount of liquid anticoagulant discharged is recorded, and the amount of liquid anticoagulant introduced minus the amount of liquid anticoagulant discharged is the amount of liquid anticoagulant adhered. Finally, the measured amount of bleeding (intuitively measured by the metering scale 31 on the measuring bottle 3) minus the amount of liquid anticoagulant adhered is closer to the actual amount of bleeding;

[0039] First, the length of the electric telescopic rod 22 is adjusted through the external controller so that the collecting chamber 1 is embedded in the middle of the nursing bed and located below the patient's buttocks. After that, the patient's bleeding can be collected through the collecting chamber 1, and the blood entering the collecting chamber 1 enters the inside of the collecting main pipe 4 and filters the larger blood clots through the filter sheet 7, while the blood without the large blood clots passes through the concave surface 61, the connecting hole 62 and the collecting branch pipe 5 and enters the inside of the measuring bottle 3;

[0040] In the process of the filter sheet 7 filtering the blood clot, the driving motor 905 can be started by an external controller to drive the incomplete gear 906 to rotate continuously. The incomplete gear 906 rotates continuously, and the reciprocating frame 907 is driven to move up and down reciprocatingly through the symmetrical meshing saw teeth 908, so that the driving rod 901 drives the cutting and knocking leaves 8 to move up and down reciprocatingly. The cutting and knocking leaves 8 that move up and down reciprocatingly can cut the blood clots on the filter sheet 7, so that the larger blood clots are cut into smaller blood clots, and the smaller blood clots can follow the subsequent blood into the interior of the measuring bottle 3;

[0041] When the cutting and striking leaves 8 cut the blood clots on the filter screen 7, the reciprocating frame 907 that reciprocates up and down can drive the linkage rod 917 to move, so that the piston block 916 can reciprocate up and down inside the air pressure chamber 915. When the piston block 916 moves downward inside the air pressure chamber 915 to below the air vent group 918, the internal air pressure of the air pressure chamber 915 increases and the internal gas will be squeezed into the axially symmetrical air pressure tube 919, so that the axially symmetrical piston rod 920 can drive the symmetrical belt rotating shaft 913 to move upward through the abutment ring 914. The upward moving belt rotating shaft 913 slides inside the vertical slide groove 912 and abuts against the inner wall of the upper inclined groove 910, so that the belt rotating shaft 913 and the abutment ring 914 rotate relative to each other and drive the sealing rotating ring 903 to rotate counterclockwise by a certain angle, and the sealing rotating ring 903 can rotate symmetrically. The belt rotating rod 904 drives the cutting and knocking leaves 8 to rotate counterclockwise by a certain angle. During the process of the piston block 916 moving upward to the top of the air vent group 918, the internal air pressure of the air pressure chamber 915 is reduced and the internal part of the axially symmetrical air pressure tube 919 presents a negative pressure, so that the axially symmetrical piston rod 920 can drive the symmetrical belt rotating shaft 913 to move downward through the abutment ring 914. The downward moving belt rotating shaft 913 slides inside the vertical slide groove 912 and abuts against the inner wall of the lower inclined groove 911. Similarly, the belt rotating shaft 913 and the abutment ring 914 rotate relative to each other and the cutting and knocking leaves 8 rotate counterclockwise by a certain angle, that is, every time the cutting and knocking leaves 8 cut a blood clot downward, the sealing rotating ring 903 can drive the cutting and knocking leaves 8 to reverse once through the symmetrical belt rotating rod 904, and every time the cutting and knocking leaves 8 reset upward, the cutting and knocking leaves 8 will reverse once in the same way;

[0042] When the liquid weight sensor 11 at the bottom of the measuring bottle 3 for collecting blood reaches a preset liquid weight sensing value, the replacement motor 13 is started to drive the driving gear 14 to rotate 90°, so that the meshing gear ring 15 drives the connecting hole 62 on the bottom block 6 to rotate 90° through the rotating cylinder 12 to align with the next collecting branch tube 5, so that the next replaced measuring bottle 3 can continue to collect blood.

[0043] The main difference between the present embodiment and the prior art is that in the process of filtering out larger blood clots through the filter mesh 7 to prevent clogging, the cutting and knocking leaves 8 located above the filter mesh 7 can reciprocate up and down and cut the blood clots, and the cutting and knocking leaves 8 that reciprocate up and down can autonomously perform intermittent reversal, so that the cutting and knocking leaves 8 can rotate and cut the larger blood clots on the filter mesh 7 in turn, and after the larger blood clots are cut into smaller blood clots, they can follow the subsequent blood into the interior of the measuring bottle 3 to reduce the measurement error of the bleeding amount.

[0044] Embodiment 2

[0045] like Figure 1-Figure 10 As shown, based on the first embodiment, the filter sheet 7 is axially symmetrically arranged in the inner middle part of the collecting main pipe 4, and a flipping mechanism 10 for driving the flipping thereof is arranged between the axially symmetrically arranged filter sheets 7, and the flipping mechanism 10 comprises a sealing fixing ring 101 fixedly connected to the inner middle side of the collecting main pipe 4 and an inner connecting ring 102 slidably connected to the outside of the driving rod 901, and a rotating rod 103 fixedly connected to the filter sheet 7 is axially symmetrically rotated between the sealing fixing ring 101 and the inner connecting ring 102, and the rotating rod 103 drives the filter sheet 7 to rotate 180° to realize flipping, so that the cutting and knocking leaf 8 knocks the cut blood clot onto the concave surface 61 and enters the inside of the connecting hole 62 along with the blood;

[0046] The flipping mechanism 10 also includes an electro-hydraulic push rod 104 axially symmetrically installed on the outside of the collecting main pipe 4, and the top of the axially symmetrical electro-hydraulic push rod 104 is fixedly connected to a sliding ring 105 slidably connected to the outside of the collecting main pipe 4, and the top of the sliding ring 105 is axially symmetrically fixedly connected to a vertical gear rod 106. The rotating rod 103 extends to the outside of the collecting main pipe 4 and is fixedly connected to a meshing gear 107 meshing with the vertical gear rod 106. By starting the electro-hydraulic push rod 104 to extend or shorten, the axially symmetrical filter mesh 7 can be turned over through the vertical gear rod 106 and the meshing gear 107, so as to achieve continued filtration of the filter mesh 7 and knock off small blood clots.

[0047] The working principle of this embodiment is as follows: when blood accumulates above the filter sheet 7 inside the collecting main pipe 4, the driving motor 905 can be turned off by the external controller to ensure that the position of the cutting and knocking leaves 8 at this time does not affect the turning over of the filter sheet 7, and then the electro-hydraulic push rod 104 is started to extend by the external controller. The extension of the electro-hydraulic push rod 104 will drive the axially symmetrical vertical gear rod 106 to move upward through the sliding ring 105, so that the meshing gear 107 rotates and drives the filter sheet 7 to rotate 180° through the rotating rod 103 to turn over, and the axially symmetrical filter sheet 7 can continue to filter the blood clots after turning over, and then the driving motor 905 is started by the external controller to allow the cutting and knocking leaves 8 to continue to move. The cutting and knocking leaves 8 that continue to move can, on the one hand, cut the large blood clots filtered above the filter sheet 7, and on the other hand, knock the small blood clots adhered to the bottom of the filter sheet 7, so that the small blood clots can fall onto the concave surface 61 and enter the interior of the measuring bottle 3 along with the blood.

[0048] The main difference between the present embodiment and the prior art is that in the process of the present embodiment rotating and cutting the blood clots in sequence by the cutting and knocking leaves 8, the axially symmetrical filter screen 7 can be turned over, and the turned over filter screen 7 can continue to filter the blood clots, and the continuously moving cutting and knocking leaves 8 can not only cut the large blood clots filtered above the filter screen 7, but also knock the small blood clots adhered to the bottom of the filter screen 7, so that the small blood clots can fall onto the concave surface 61 and enter the interior of the measuring bottle 3 along with the blood, which can further prevent the adhesion of blood clots, thereby further reducing the measurement error of the bleeding amount.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
