Detailed Description
Referring to fig. 1 to 2 together, the present embodiment provides a low-dose negative angle injector for cancer patients, which is mainly used for the problem of incomplete liquid residue in needle liquid injection caused by poor turning of cancer patients, and the injector is already in actual research and development stage.
The small-dose negative angle injector for the cancer patient comprises a needle tube body 2, a functional component, a communicating tube 13, a pressure block 11, an elastic supporting wire 10, a liquid storage cavity 12 and a pushing block 4. The functional component comprises a liquid storage tube and a syringe; the liquid storage tube for pre-storing the medicament and the injection tube for injecting the medicament are arranged in the needle tube body 2 at intervals, the mode of interval arrangement can ensure that the storage and the output of liquid have the effect of mutual noninterference, and the mode of interval arrangement can be equidistant intervals or non-equidistant intervals. The pressure block 11 that is used for intraductal sliding connection to be used for intraductal pressure to change is connected to the sliding in the stock solution pipe, and pressure block 11 is located stock solution chamber 12 and with stock solution pipe flexonics's elastic support silk 10 between, and the setting of pressure block 11 helps the intraductal liquid of stock solution to carry out continuous flow and rises, can not cause remaining, and concrete process is: when the liquid storage tube is filled with liquid, the liquid can slowly accumulate from the upper surface of the pressure block, at this time, a part of the plane of the liquid medicament is lower than the connection part of the communicating tube 13 communicated with the liquid outlet tube, at this time, the external pressure is required to perform pressure action on the liquid in the lower area, so that the liquid is promoted to move upwards, and siphoning action or direct pressure action can be performed according to the quantity of the moved liquid. The pushing block 4 is slidably connected in the injection tube and is positioned between the liquid outlet cavity 3 and the first pressure cavity 5, and the pushing block 4 is used for controlling the pressure in the liquid outlet tube, so that the pushing of the liquid medicament and the change of the pressure can be conveniently carried out in time. The first pressure chamber 4 is communicated with the second pressure chamber 9 arranged in the liquid storage pipe through the rectangular channel 8, the liquid storage chamber 12 is communicated with the liquid outlet chamber through the communicating pipe 13, as shown in the attached drawing 2, one end of the communicating pipe 13 close to the liquid storage chamber 12 is lower than one end close to the liquid outlet chamber 3, and the technical scheme integrally forms a siphon structure, improves the fluidity of liquid, and is specifically as follows: the liquid storage cavity 12 and the liquid outlet cavity 3 are in a sealed state in advance, and the communicating pipe 13 forms siphon through negative pressure to perform liquid flow when the liquid in the liquid storage cavity 12 and the communicating pipe 13 are in the same height near one end of the liquid outlet cavity 3 according to the siphon principle.
The injection head 1 is detachably connected to one end of the injection tube, when the injection head 1 is used, the head needs to be sealed and closed firstly, the stability of air pressure in the tube is guaranteed, after the liquid storage tube stores liquid, the injection head 1 is opened for pressure change, a liquid medium is drained to enter, and the other end of the injection head is movably connected with the push head 6 for compressing air in the cavity. An elastic supporting wire 10 for supporting is arranged inside the second pressure cavity 9, one end of the elastic supporting wire is flexibly connected with the liquid storage pipe, and the other end of the elastic supporting wire is connected with the pressure block 11. One end of the liquid storage tube is detachably connected with a liquid suction head 14 for absorbing media, the other end of the liquid storage tube is closed, the closed arrangement is used for sealing air pressure in the tube, and the embodiment is based on the use of a needle tube and adopts a direct closing mode, including but not limited to mechanical sealing, labyrinth sealing, liquid sealing and other methods. The needle tube body 2 is detachably connected with the shielding cover 7 for sealing dust, the surface of the shielding cover 7 is paved with a copper material for wear resistance, and the paved material can be replaced in a correlated way, so long as the paved material has a wear-resisting effect, for example, ceramics, nylon, ferroalloy and the like can be subjected to wear-resisting arrangement.
The medical staff pre-injects the prepared medicament into the liquid storage tube in advance, simultaneously seals the mouth of the liquid outlet tube to form a relatively airtight pressure space, then carries the prepared medicament needle tube for guiding the patient to inject before the patient is put on a bed, the patient only needs to slightly turn over, the medical staff removes the sealing material of the liquid outlet tube connected with the needle head, the medicament in the liquid storage tube can be moved to the liquid outlet tube under the siphoning action to inject, and the whole flowing process is carried out in a negative pressure environment, so that the medical staff can realize injection only by normally and slowly pushing the push head without observing the liquid in the tube, the problem that the injection angle of the cancer patient cannot be well turned over is the injection negative angle is solved, the injection efficiency is improved by the medical staff, the waiting injection time of the cancer patient is reduced, and the injection is efficient and convenient.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
