A sealed support plate package of a catheter delivery device includes a sterile bag 1 and a support plate 2, the support plate 2 is arranged in the sterile bag 1, and the opposite sides of the support plate 2 are folded to be provided with first flanges 3. At least two first straight holes 4 are formed in the middle of the support plate 2, and the clamping belt 5 is formed by folding along the first straight hole 4. The clamping belt 5 is provided with a clamping card 51 and a clamping slot 52, and the clamping belt 5 is staggered with the clamping slot 52 to be provided with a gap 53 on both sides. The side of the support plate 2 away from the clamping belt 5 is folded to be provided with a flap 6. The sterile bag 1 is heat-sealed and adhered, so that the support plate 2 is sealed in the sterile bag 1. The sterile bag 1 is divided into an upper film 7 made of PET / PE adhesive and a lower film 8 made of TYVEK. The upper film 7 and the lower film 8 are heat-sealed and adhered at the end edges.

[0030] The support plate 2 is provided with a second straight hole 9, and the flap 6 is provided with a second flange 10, and the second flange 10 and the second straight hole 9 make the flap 6 have a certain degree of folding cooperation. The two sides of the flap 6 are provided with arc-shaped grooves 11, and the two ends of the arc-shaped grooves 11 extend to the two ends of the flap 6 respectively, and folding along the arc-shaped grooves 11 makes the flap 6 form a flip cover 12. A plurality of misaligned arc-shaped grooves 13 are further arranged between the flap 6 and the tape 5. The two ends of the tape 5 are respectively provided with a mounting hole 14 and a hanging buckle 15 matched with the mounting hole 14.

[0031] In order to facilitate the use of the catheter conveyor, prevent the pre-installed battery from causing continuous charging and discharging of the battery, reduce the service life, and prevent the battery from leaking and being polluted due to long-term non-use. The preferred technical solution further comprises: the support plate 2 is further detachably connected with a battery bag 16 through the mounting hole 14 and the hanging buckle 15. The hanging buckle 15 of the tape 5 and the battery bag 16 is foldably provided with a limiting piece 17, which can be inserted into the mounting hole 14 when folded, and the folded state is released after insertion. The limiting piece 14 is in interference fit with the mounting hole 15, so as to fix the battery bag. Similarly, the flap 6 extends out a plug 18 in a direction away from the arc-shaped groove 11, and the support plate 2 is provided with a plug groove 19 matched with the plug 18, and the plug 18 is provided with a limiting piece 17.

[0032] Fixed through the mounting hole-hanging buckle structure. Or after the flap 6 wraps the support plate conveyor, the flap 6 can be limited from the outside of the support plate through a sterile bag 1 matched in size with the support plate 2.

[0033] Firstly, the support plate shown in the utility model is obtained by die cutting corresponding plate material using corresponding die cutting mold, then the first flange on both sides is turned out along the crease, the first flange is used for supporting the sterile bag and making the support plate have a certain thickness (more than 1cm), facilitating subsequent transportation and stacking related instruments to reduce bumping; the support conveyor is placed on the support plate, is turned into a card tape along the first straight hole, the card of the card tape is inserted into the card slot of the body to fix the conveyor handle, after the card is folded along the dotted line, the card can be pulled in one of the card slots to tighten, after tightening, the folded state gap limits the card tape, so that the size of the handle is adjusted and fastened. The gap can reduce the card jam caused by pulling action, and has a certain elastic change to prevent breakage. Then the circular arc groove is turned up, the catheter sheath is clamped into the misaligned circular arc groove, and the circular arc groove is folded to turn out a semicircular piece to fix the catheter sheath; the turning plate is buckled along the crease of the support plate, and is fixed through the second flange and the second long hole to prevent the support conveyor from moving, preferably, the turning plate is folded along the arc-shaped groove to become a flip cover, compared with the turning plate which is not resistant to the pressure perpendicular to the turning plate, the protection effect of the flip cover is better. The battery bag is also detachably installed on the support plate, to avoid interference and collision between the battery bag and the support conveyor, the battery bag and the support conveyor are installed on both sides of the support plate respectively. The use of the support conveyor is facilitated, and the battery needs to be found separately. The mounting hole and the hanging buckle are locked by the limiting piece of the hanging buckle, and the specific operation is as follows: fold the limiting piece of the hanging buckle to be smaller than the diameter of the mounting hole, then pass the hanging buckle through the mounting hole, and finally restore the folded limiting piece to achieve locking by interference fit. The arc-shaped groove can also adopt a similar folding structure of the plug-in piece, the plug-in slot and the limiting piece, but for the long hole, the limiting piece can only be folded to achieve locking effect, so it is not necessary to restore the folded state. The upper layer of the sterile bag adopts PET / PE composite material, and the lower layer uses flash evaporation non-woven fabric, such as TYVEK material. When the upper layer uses PET / PE composite material, it is a transparent structure, which facilitates direct observation of the state of the catheter conveyor in the package. The utility model combines HDPE to make the support plate, which has simple structure and strong practicability, is suitable for ethylene oxide sterilization and radiation sterilization, and increases the protection of the instrument.

[0034] The above only describes the preferred embodiments of the utility model, and it should be pointed out that for ordinary technical personnel in the technical field, without departing from the technical principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection range of the utility model.
