Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a kind of irradiation cup applied to on irradiation instrument. BACKGROUND

[0002] X-ray biological irradiation instrument is a kind of analytical instrument for biology, basic medicine, pharmacy field, mainly for cancer biology, human genome, induced genetic change, stem cell, small animal irradiation, cell culture and division inhibition research, T-B cell research and blood cell, bone marrow transplant irradiation, transplant immunity, immunosuppressive therapy, radiosensitivity research, DNA damage research, food irradiation, microbial inactivation, plant and seed irradiation etc.

[0003] The lead room of irradiation instrument is the place where irradiation product receives irradiation in the irradiation instrument, and the lead room is in the form of a square box structure, a ball tube is installed at the back plate of the lead room, and a plurality of irradiation cups are arranged around the outer periphery of the ball tube in the lead room for containing irradiation products, such as blood bags. During irradiation, the plurality of irradiation cups revolve around the ball tube, and at the same time, the irradiation cups also rotate, so as to avoid that the irradiation cups only have one side facing the ball head.

[0004] As shown in Figure 1 Further explanation of the movement posture of the irradiation cup: the irradiation cup is in the form of a cylinder, the axis of the ball tube 1 and the irradiation cup 2 is arranged in a horizontal direction in the lead room, and the vertical direction upper part of the irradiation cup at any position during revolution around the ball tube is taken as a mark point, and the mark point is always located above the vertical direction irradiation cup 2 during revolution.

[0005] Since the irradiation cup is arranged around the outer periphery of the ball tube, X-rays mainly enter along the side wall of the columnar surface of the irradiation cup, and in combination with the movement posture of the irradiation cup in the lead room, the irradiation intensity at the axis of the irradiation cup is lower than that at the side wall of the irradiation cup, and the position of the ball tube is located in the middle of the axis direction of the irradiation cup, therefore, the irradiation intensity at both ends of the irradiation cup is smaller than that at the middle of the irradiation cup, and the irradiation intensity received by the irradiation products at different positions in the irradiation cup is different. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims at providing an irradiation cup, which can make the irradiation of the irradiation products in the irradiation cup more uniform, and improve the irradiation effect of the irradiation instrument.

[0007] The technical scheme of the utility model is as follows:

[0008] An irradiation cup, comprising a cup body and a cup cover, the cup body is in the form of a cylinder, the cup cover is detachably connected with the cup body, a handle is arranged on the outer side of the cup cover, and a spherical crown-shaped top block is arranged at the center of the inner side of the cup cover.

[0009] Since the irradiation intensity at the axis of the irradiation cup is low, and the irradiation intensity at the positions at both ends of the axis is even lower, the utility model discloses a top block is arranged at the middle of the inner side of the cup cover to occupy the position with low irradiation intensity in the irradiation cup, thereby improving the uniformity of the irradiation intensity in the irradiation cup, and improving the irradiation effect.

[0010] Specifically, the detachable connection between the cup cover and the cup body is generally achieved by thread connection or rotary buckle connection, and the cup cover needs to rotate relative to the cup body during the cup cover clamping process. In order to effectively utilize the space in the irradiation cup, the irradiation product is usually filled in the irradiation cup, and the top block will rub against the irradiation product during the cup cover clamping rotation. Taking a common irradiation product, a blood bag, as an example, the rubbing process will increase the probability of the blood bag damage, and the smooth spherical cap-shaped top block can effectively reduce the probability of the blood bag damage.

[0011] The ratio of the height of the top block to the diameter of the ball where the top block is located is 1:30-1:20.

[0012] The curved surface of the spherical cap-shaped top block has a certain reflection effect on X-rays, the height of the top block is set to be small, and X-rays are more conducive to being reflected to the axis of the irradiation cup, thereby improving the intensity of X-rays at the axis of the irradiation cup, and improving the uniformity of the irradiation intensity in the irradiation cup,

[0013] The handle, the cup cover and the top block are connected through a screw, and the side of the top block close to the cup cover is provided with a threaded blind hole matched with the screw.

[0014] The handle, the cup cover and the top block are separately processed and then assembled, the screw is inserted from one side of the handle, the smoothness of the spherical surface of the top block can be ensured, the friction with the irradiation product during clamping is reduced, and the probability of irradiation product damage is reduced.

[0015] The material of the top block is aluminum, boron carbide or a material with low atomic number and a composite thereof.

[0016] The above-mentioned materials have good reflection effect on X-rays, and are more conducive to the reflection of X-rays to the axis of the irradiation cup.

[0017] The inner side of the bottom wall of the irradiation cup is provided with a spherical cap-shaped top block.

[0018] The utility model has the advantages and positive effects that: due to the above technical scheme, the position occupation and reflection effect of the top block can effectively improve the uniformity of the irradiation intensity in the irradiation cup, and the damage to the irradiation product is small.
