Description

Technical Field

[0001] The present invention relates to the technical field of obstetric care equipment, and particularly to a postpartum predictive blood loss monitoring and nursing device. Background Art

[0002] Childbirth refers to the emergence of a new individual from the mother's body; specifically, it refers to the period and process during which the fetus detaches from the mother's body and exists independently. After vaginal delivery, bleeding generally occurs. In order to deal with the bleeding after childbirth, medical staff will provide predictive care to the parturient. During the process of predictive care, it is necessary to measure the amount of blood flowing out of the mother's body to ensure the personal safety of the mother.

[0003] For this reason, the Chinese patent with the publication number "CN216090462U" discloses "a device for measuring predictive care blood loss after vaginal delivery". Its main structure includes a horizontally arranged bottom plate. A bearing plate that can vertically approach or move away from the bottom plate is arranged on the top of the bottom plate. A groove that fits the human body is constructed on the top of the bearing plate, and a number of through holes are opened in the groove. The device for measuring predictive care blood loss after vaginal delivery can adjust the height between the bearing plate and the patient's buttocks by vertically approaching or moving away the bearing plate from the bottom plate. During the process of predictive care, the blood flowing out of the patient's vagina will flow into the collection cylinder through the through holes in the groove. Then, the volume of the blood inside can be observed according to the volume scale on one side of the collection cylinder. After the device is used, the collection cylinder can be taken out of the installation groove, which is convenient for cleaning and disinfecting the collection cylinder. And after cleaning, the collection cylinder can be re - clamped into the installation groove through the clamping component.

[0004] However, when the above - mentioned device for measuring predictive care blood loss after vaginal delivery collects blood flow, due to the viscosity of the blood, some blood will adhere to the surface of the structures it contacts, and the adhered blood cannot flow into the collection cylinder normally, resulting in insufficient measurement of the actual blood discharge volume of the parturient and relatively low accuracy. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a postpartum predictive blood loss monitoring and nursing device, which uses a quantitative cleaning liquid to clean the blood adhering to the surface of the structure, so that the blood and the cleaning liquid can be simultaneously discharged into the liquid collection cylinder. Since the amount of the cleaning liquid used is a known number, an accurate blood volume can be obtained, thereby reducing the occurrence of insufficient measurement caused by blood adhesion, and further improving the accuracy of detecting the blood discharge volume, and solving the above - mentioned technical problems.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figure 1 and Figure 2, A postpartum predictive blood volume monitoring and nursing device, including a bottom support substrate 1, a liquid collection cylinder 2 located directly above the bottom support substrate 1, a collection cavity 4 provided inside the liquid collection cylinder 2 with an open top, and scale values 3 provided on the outer circumferential surface of the liquid collection cylinder 2 for displaying the liquid volume in the liquid collection cylinder 2. After the liquid collection is completed, the liquid collection cylinder 2 is removed. By observing the scale values 3 on the surface of the liquid collection cylinder 2, the sum of the blood volume and the cleaning liquid volume at this time can be known. Subtracting the known cleaning liquid volume from this sum gives the actual blood discharge volume of the parturient.

[0024] To reduce blood adhesion, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , it is necessary to set up a liquid guiding and collecting mechanism 5, which internally has a rectangular collecting housing 51 installed at the top of the liquid collection cylinder 2, a conical liquid flow cavity 53 provided at the center of the rectangular collecting housing 51 for concentrating and discharging blood into the collection cavity 4, multiple liquid flushing holes 56 provided on the outer periphery of the circumferential surface of the conical liquid flow cavity 53 and capable of making the cleaning liquid flush the wall surface of the conical liquid flow cavity 53 with an eddy current effect, and an annular liquid flow cavity 55 for supplying flushing liquid to the multiple liquid flushing holes 56. The liquid required for cleaning will enter the annular liquid flow cavity 55 along the rectangular liquid flow cavity 57, and then enter the cylindrical liquid flow cavity 52 through the multiple liquid flushing holes 56. Since the liquid flushing holes 56 are connected to the circumferential surface of the communicating cylindrical liquid flow cavity 52 in a tangential manner, the cleaning liquid entering the cylindrical liquid flow cavity 52 will enter the conical liquid flow cavity 53 in an eddy current manner, thereby flushing the blood attached to the surface of the conical liquid flow cavity 53, enabling the blood to enter the liquid collection cylinder 2 to the greatest extent, and thus reducing the blood adhesion phenomenon.

[0025] Regarding the specific structure of the liquid guiding and collecting mechanism 5, please refer to Figure 3 , Figure 4 and Figure 5, including a rectangular collection housing 51, a cylindrical liquid flow cavity 52 with an open top is provided at the center of the rectangular collection housing 51, a conical liquid flow cavity 53 with an upper opening diameter larger than the lower diameter is provided at the bottom end of the cylindrical liquid flow cavity 52, a bottom mounting port 54 for clamping the top port structure of the liquid collection cylinder 2 is provided at the bottom end of the conical liquid flow cavity 53, an annular liquid flow cavity 55 is provided on the periphery of the circumferential surface of the cylindrical liquid flow cavity 52 in the rectangular collection housing 51, a plurality of liquid flushing holes 56 are provided between the circumferential inner wall of the annular liquid flow cavity 55 and the circumferential surface of the cylindrical liquid flow cavity 52, two symmetric rectangular liquid flow cavities 57 are provided outside the annular liquid flow cavity 55, and two first liquid flow holes 58 communicating the bottom surface of the rectangular liquid flow cavity 57 and the bottom surface of the rectangular collection housing 51 are provided inside the rectangular collection housing 51.

[0026] In order to utilize the weight of the parturient to achieve the directional driving function of the cleaning liquid, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , two cleaning liquid driving mechanisms 6 need to be provided. Inside, there is a longitudinal hollow support rod 61 fixedly installed on the upper surface of the bottom support substrate 1 and hollow inside, a piston body 68 placed inside the longitudinal hollow support rod 61 and capable of achieving the directional driving effect of the cleaning liquid during longitudinal movement, and a longitudinal movable rod 610 that moves with the piston body 68 and can support the rectangular collection housing 51. Before work, the flushing liquid injection channel 67 needs to be connected to the drain port of a cleaning liquid storage tank at a higher horizontal height relative to the device through a pipeline. When the parturient sits on the upper surface of the rectangular collection housing 51, under the weight of the parturient, the piston body 68 will move downward. At this time, the space above the piston body 68 increases and the air pressure decreases, sucking the cleaning liquid into the conical liquid flow cavity 53. When the blood discharge of the parturient is completed, the parturient leaves the rectangular collection housing 51. Under the elastic action of the spiral spring 69, the piston body 68 will move upward. At this time, the cleaning liquid located above the piston body 68 will move upward along the longitudinal movable rod 610, thereby utilizing the weight of the parturient to achieve the directional driving function of the cleaning liquid.

[0027] Regarding the specific structure of the cleaning liquid driving mechanism 6, please refer to Figure 6 and Figure 7, including a longitudinal hollow support rod 61. A bottom fixing plate 62, which is integrally structured with the longitudinal hollow support rod 61 and fixedly installed on the upper surface of the bottom support substrate 1, is provided at the bottom of the longitudinal hollow support rod 61. A middle component moving cavity 64 is provided in the middle region of the longitudinal hollow support rod 61. A bottom component moving cavity 63 is provided at the bottom end of the middle component moving cavity 64. A top component moving cavity 65 is provided at the top end of the middle component moving cavity 64. A rod body perforation 66 is provided at the top end of the top component moving cavity 65. A flushing liquid injection channel 67, which is used to inject cleaning liquid into the top component moving cavity 65 and has a first liquid one-way valve 614 installed inside, is provided on the circumferential side surface of the longitudinal hollow support rod 61. A piston body 68, which can move axially along the middle component moving cavity 64, is placed inside the longitudinal hollow support rod 61 at the position of the middle component moving cavity 64. A spiral spring 69, which is located inside the middle component moving cavity 64 and the bottom component moving cavity 63, is installed at the bottom end of the piston body 68, and the spiral spring 69 is in a compressed state. A longitudinal moving rod 610, which penetrates through the rod body perforation 66, is fixedly installed on the upper surface of the piston body 68. A top fixing plate 612, which is integrally structured with the longitudinal moving rod 610 and fixedly installed on the bottom surface of the rectangular collection housing 51, is provided at the top end of the longitudinal moving rod 610. A third liquid flow hole 613, which communicates with the first liquid flow hole 58, is provided inside the longitudinal moving rod 610, and a second liquid one-way valve 615 is installed inside the third liquid flow hole 613. A second liquid flow hole 611, which communicates the third liquid flow hole 613 and the top component moving cavity 65, is provided on the circumferential surface of the longitudinal moving rod 610 near its bottom. The structural radius of the rod body perforation 66 is smaller than the structural radius of the top component moving cavity 65. The structural radius of the top component moving cavity 65 is smaller than the structural radius of the middle component moving cavity 64. The structural radius of the middle component moving cavity 64 is larger than the structural radius of the bottom component moving cavity 63, and the depth of the bottom component moving cavity 63 is greater than the elastic height of the spiral spring 69 after being completely compressed. The liquid discharge port of the first liquid one-way valve 614 faces the direction where the top component moving cavity 65 is located. The liquid inlet port of the second liquid one-way valve 615 faces the direction where the second liquid flow hole 611 is located.

[0028] In use, a flushing liquid needs to be injected into the channel 67, which is connected through a pipeline to the drainage port of a cleaning liquid storage tank that is at a higher horizontal height relative to the device. Then, the rectangular collection housing 51 is pressed downward and then the pressure on the rectangular collection housing 51 is released. When the cleaning liquid can first flow out along the cylindrical liquid flow cavity 52, the liquid collection cylinder 2 is installed at the bottom installation port 54. Then, the parturient sits on the upper surface of the rectangular collection housing 51. Under the weight of the parturient herself, the piston body 68 will move downward. At this time, the space above the piston body 68 increases and the air pressure decreases, sucking the cleaning liquid into the conical liquid flow cavity 53. When the blood discharge of the parturient is completed, the parturient leaves the rectangular collection housing 51. Under the elastic action of the spiral spring 69, the piston body 68 will move upward. At this time, the cleaning liquid located above the piston body 68 will move upward along the longitudinal movable rod 610, and the liquid required for cleaning will enter the annular liquid flow cavity 55 along the rectangular liquid flow cavity 57, and then enter the cylindrical liquid flow cavity 52 through a plurality of liquid flushing holes 56. Since the liquid flushing holes 56 are connected to the circumferential surface of the cylindrical liquid flow cavity 52 in a tangential manner, the cleaning liquid entering the cylindrical liquid flow cavity 52 will enter the conical liquid flow cavity 53 in a vortex manner, thereby flushing the blood attached to the surface of the conical liquid flow cavity 53, enabling the blood to enter the liquid collection cylinder 2 to the greatest extent. After taking the liquid, the liquid collection cylinder 2 is removed. By observing the scale value 3 on the surface of the liquid collection cylinder 2, the sum of the blood volume and the cleaning liquid volume at this time can be known. Subtracting the known amount of the cleaning liquid from this sum is the actual blood discharge volume of the parturient.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
