The application discloses a hemodialysis sufficiency evaluation method based on sodium balance, and relates to the technical field of hemodialysis, and the method comprises the following steps: obtaining the body weight, dry body weight and serum sodium concentration of a patient before dialysis; calculating a target sodium removal amount Na_target=DeltaW* [Na]s / 0.93, and establishing a quantitative equivalent relationship between the body weight increase and sodium accumulation; obtaining or calculating an actual sodium removal amount (including two ways of convection and diffusion); calculating a sodium removal ratio R_Na=Na_actual / Na_target; and evaluating the dialysis sufficiency according to the R_Na. The application firstly changes the dialysis sufficiency evaluation from 'urea removal' to'sodium and water removal', and directly aims at the main pathological burden of kidney failure patients, i.e. sodium and water retention. The sodium removal ratio R_Na is more directly related to the volume state and cardiovascular prognosis of the patient than the traditional Kt / V index. The method only needs the body weight and serum sodium before and after dialysis to be calculated, and can be integrated into the existing dialysis information system.

The utility model discloses a Chinese herbal medicine planting water conservation fertilization device, including drip irrigation tape body still includes drop -fertilizing mechanism, drop -fertilizing mechanism includes base plastic piece, bend cut muscle piece, spin -on pipe, spin -connected pipe, hollow spin column, four -hole core sac and side handle head, the inner tape surface of drip irrigation tape body is bonded with base plastic piece, set up drop -fertilizing mechanism at the drip irrigation tape body, and the bend cut muscle piece of drop -fertilizing mechanism and the water passage caliber of spin -on pipe, spin -connected pipe and other components constitute are bigger, can effectively reduce the risk of impurity stagnation, and the porous leakage structure of four -hole core sac is the key position of drip irrigation, but its installation on the design of hollow spin column makes liquid flow path more smooth, and the stable soil -removing water -out environment formed when the taper head of cooperation conical cylinder inserts the soil, effectively reduced the drip irrigation tape blockage probability when Chinese herbal medicine planting water conservation fertilization, and drop -fertilizing mechanism adopts modularization detachable design, and cleaning operation is convenient and efficient.

Pond (1) for water retention in the landscape, wherein the pond (1) comprises a water reservoir (2) and an earth embankment (3) for water retention, wherein the earth embankment (3) surrounds the water reservoir (2) over at least one quarter of the circumference of the water reservoir (2), wherein the water reservoir (2) comprises a bottom (7) of the water reservoir (2), characterized in that the pond (1) further comprises an underground clay layer (4) for limiting the escape of water from the water reservoir (2) by underground seepage, wherein the underground clay layer (4) is arranged under at least a part of the earth embankment (3), wherein at least a part of the earth embankment (3) is in contact with the underground clay layer (4).

This utility model relates to the technical field of shower head (overhead spray) drainage, and in particular to a device for quickly draining residual water, comprising a main body having an inlet chamber and an outlet chamber, an inner body, a sealing element, and a return spring. The sealing element includes a plug, a first sealing part, and a second sealing part, used to close the inlet channel and connect the drain chamber to the atmosphere, respectively. When the water is turned off, the return spring drives the sealing element to return to its original position, opening the drain chamber and the air inlet chamber to quickly drain residual water; when the water is turned on, the water flow pushes the sealing element to close the drain chamber and the air inlet chamber, opening the inlet channel. This device ensures stable movement of the sealing element through guide strips, buckles, and other structures, and utilizes raised features to accelerate the water shut-off time. This utility model can effectively reduce residual water retention in the cavity, reduce the risk of bacterial growth, and requires no electricity, has a simple structure and low cost, significantly improving user experience and safety.

This utility model discloses a storage device for processing celery, comprising: a placement rack, a placement limiting groove on the front surface of the placement rack, a water guide plate fixedly connected to the lower surface of the placement rack, a water guide groove on the side wall of the water guide plate, a sealing baffle fixedly connected to the lower surface of the placement rack, a drainage block fixedly connected to the side wall of the placement rack, a water storage tank on the upper surface of the drainage block, and a connecting groove on the inner surface of the water storage tank. The placement limiting groove precisely engages the celery container, preventing it from shifting during storage or slight movement, thus ensuring storage stability. The water guide plate catches dripping water from the container, the water guide groove quickly guides the water flow, preventing water accumulation and impurity growth at the bottom of the placement rack, the drainage block provides support, the water storage tank temporarily stores water, the connecting groove connects to the drainage path to prevent water retention, and the sealing baffle effectively prevents water leakage.
