The utility model relates to medical equipment technical field, specifically disclose a detachable infusion regulator, including can combine and separate first side combination shell and second side combination shell, still include: connecting structure, set up one contact's edge portion of first side combination shell and second side combination shell, first side combination shell and second side combination shell can rotate around the edge portion and realize the opening and closing action, guide structure, fixedly arranged on the inner wall surface among first side combination shell and / or second side combination shell, all -round has promoted the practicality and reliability of infusion regulator, effectively solved the operation of traditional infusion regulator possibly existing, the problem such as inaccuracy of adjustment and stability deficiency, provided high -efficient, safe infusion operation tool for medical staff, greatly optimized infusion process, has important significance in medical practice.

The utility model discloses a deformable working tape stamping die for backward extrusion forming, which is characterized in that a handle accommodating cavity is arranged in the connecting end of a stamping rod, and an annular convex shoulder is arranged on the connecting end surface of the stamping rod; the punch comprises a punch handle part and a punch working part, the punch handle part is arranged on the tail end face of the punch working part, a pin hole is formed in the punch handle part, the pin hole is connected with the handle part containing cavity in a matched mode through a joint pin, an adjusting gap is formed between the pin hole and the joint pin, and an annular cavity is formed in the tail end face of the punch working part; a working belt is arranged on the periphery, close to the tail end face, of the punch working part. According to the utility model, the annular cavity at the end part of the punch is matched with the annular convex shoulder of the punch rod, so that the diameter of a working belt of the punch can be increased in the working stroke and can be reduced in the return stroke, thereby reducing the demolding force, enabling the punch to be easy to separate when being lifted, reducing the demolding procedures of the punch, realizing the repeated use of the punch, and reducing the production cost. And the production cost is reduced.

The invention discloses an atmospheric neutron shielding device, which comprises a sample thyristor 1, a protective resistor 2, a measuring resistor 3, data acquisition equipment 4, a direct current voltage source 5, an artificial neutron source 6, an aluminum alloy plate 7, a first nylon plate 8, a second nylon plate 9, a screw 10 and a shielding material layer 11, wherein the direct-current voltage source 5, the protective resistor 2, the measuring resistor 3 and the sample thyristor 1 form a main loop; the grounding end of the direct-current power supply 5 is grounded and is used for providing direct-current bias voltage with variable polarity and adjustable amplitude for the sample thyristor 1; one end of the protective resistor 2 is connected with the output end of the direct-current power supply 5, and the other end is connected with one end of the sample thyristor 1; one end of the measuring resistor 3 is connected with the low-voltage side of the sample thyristor 1, the other end of the measuring resistor 3 is grounded, and loop current is obtained by monitoring voltages at two ends of the measuring resistor 3; the sample thyristor 1 is arranged in a neutron beam channel of the artificial neutron source 6 and is protected by the shielding material layer 11.
