the rack locking device is characterized in that a limiting piece is arranged on the second locking plate in a sliding mode through a sliding groove and connected with the shifting piece, and an opening through which a rack can pass conveniently and an expansion opening through which the limiting piece can deform conveniently are formed in the second locking plate.

The utility model has the advantages that:

by using injectable enema, the patient can operate himself if the catheter is sufficiently long.

Through set up the recess on the catheter, can promote the pipe wall intensity of catheter, when adopting soft materials, promote the intensity of catheter through the structure of recess, be convenient for reduce the damage to anus and rectum mucosa. The liquid separation head at the end of the liquid guide pipe improves the speed of the glycerine enema flowing out of the micropores, and the distribution area of the glycerine enema is wider.

The connector enables the connection and the disassembly of the syringe and the catheter to be more convenient, after the injection is finished, the syringe is disassembled, so that the pressure inside and outside the catheter can be balanced, the residual enema liquid inside can flow out through the micropores, the medicine residue is reduced, and the waste of the liquid medicine is avoided.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes will be apparent to those skilled in the art as long as they are within the spirit and scope of the present invention as defined and defined by the appended claims, and all inventions contemplated by the present invention are protected.

Example 1

As shown in figures 1-3, the injection type enema comprises a syringe 1 and a catheter 2. The syringe 1 is connected with a leak-proof cap 4 by screw thread to be convenient for individual storage, and the enema 3 is stored inside. The catheter 2 is in a strip-shaped tubular shape and has a longer length, so that the operation of a patient is facilitated. One end of the catheter 2 is provided with a connector 7 connected with the injector 1, the other end is a smooth closed end, the closed end is provided with a plurality of micropores 5, and the micropores 5 cover the front end of the catheter 2 by the length of 0.8 cm-2 cm, so that the enema 3 can be conveniently dispersed. The connector 7 facilitates quick mounting and dismounting of the syringe 1 and the catheter 2. After the injection is finished, the injector 1 and the catheter 2 are quickly separated through the connector 7 so as to balance the internal and external pressure of the catheter 2, so that the residual glycerine enema 3 in the catheter 2 can be quickly discharged from the micropore 5, and the waste of the glycerine enema 3 is avoided.

Example 2

In the present embodiment, as shown in fig. 4 to 6, the connector 7 includes an arc-shaped body 701 and a first locking plate 704 and a second locking plate 703 provided on the arc-shaped body 701; the arc-shaped body 701 is provided with a plurality of tooth heads 702. The first locking plate 704 is provided with a rack 705.

The second locking plate 703 is provided with a limiting piece 708 through a sliding groove 709 in a sliding manner, the limiting piece 708 is connected with the shifting piece 706, and the second locking plate 703 is provided with an opening for facilitating the rack 705 to pass through and an expansion opening 707 for facilitating the deformation of the limiting piece 708.

In the using process, the first locking plate 704 and the second locking plate 703 are strongly kneaded, the rack 705 penetrates through the second locking plate 703 to be matched with the limiting piece 708, the rack 705 presses the limiting piece 708 in the process that the rack 705 penetrates through the second locking plate 703, and the expanded opening 707 provides a deformation space for the limiting piece 708 in the pressing process, so that the matching length of the rack 705 and the limiting piece 708 can be conveniently controlled through force. In the process that the rack 705 passes through the second locking plate 703, the two ends of the arc-shaped body 701 are also bent inwards, so that the tooth heads 702 on the arc-shaped body 701 are driven to press the liquid guide pipe 2, the extrusion force of the arc-shaped body 701 on the liquid guide pipe 2 is improved, and the sealing performance is improved.

After use, the pushing-pulling piece 706 slides in the sliding groove 709, and the stopper 708 slides out of the second locking plate 703, so that the stopper of the stopper 708 and the rack 705 is disabled, the first locking plate 704 and the second locking plate 703 return to the initial position, the catheter 2 is no longer pressed by the tooth head 702, and the syringe 1 is separated from the catheter 2. In the whole process, the operation can be carried out by one hand, so that the operation of the patient is facilitated.

Example 3

In this embodiment, the liquid guiding tube 2 is provided with a plurality of grooves 6, and the liquid guiding tube 2 is internally provided with a liquid separating head 601 at the end. The liquid separation head 601 reduces the inner diameter of the liquid guide tube 2 in the area, and can improve the flow rate of liquid discharged from the micropore 5 area and improve the dispersion speed of the glycerine enema 3 under the condition that the pressure of the injector 1 is not changed, thereby improving the curative effect.
