[0002] Postoperative pelvic adhesions have always been a headache for many obstetricians and gynecologists, and there is an urgent need for effective methods to prevent adhesions in clinical practice. Relevant studies have shown that 60% to 90% of obstetricians and gynecologists will develop adhesions after pelvic and abdominal surgery, and up to 20% of patients will experience chronic abdominal pain after abdominal surgery, of which about 57% of chronic pain is related to adhesions. Currently, the disposable syringes used in clinical trials are mainly single-unit syringes. When clinical practice requires instant mixing of two liquid preparations to achieve the best efficacy, single-unit syringes will be more difficult to achieve.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0027] See also Figure 1-3 , the utility model provides a technical solution:

[0028] A spray glue dispenser includes a syringe card slot plate 1 and an adapter 3. The syringe card slot plate 1 is provided with at least two card slots 10 for placing a syringe body 2. The syringe body 2 is placed in the card slots 10 from top to bottom and the injection head 20 of the syringe body 2 faces outward. Each card slot 10 is provided with a clamping assembly 12 for clamping the injection tube body 22 of the syringe body 2. The bottom of the plurality of card slots 10 is provided with a connecting frame 13 for driving the injection push rods 21 of the plurality of syringe bodies 2 to move synchronously. The adapter 3 includes a plurality of plugs 30 for sealingly connecting the plurality of injection heads 20 respectively. Each plug 30 is connected to the same mixing tube cavity 32 through a confluence branch pipe 31. The mixing tube cavity 32 is provided with an air pressure regulating mechanism. The outer end of the mixing tube cavity 32 is provided with a nozzle 36 for drug administration, and the nozzle 36 is provided with a filter membrane 35 for filtering.

[0029] When working, Figure 1As shown, two card slots 10 are provided here, that is, a double-linked setting, one of which can be configured with A solution and the other with B solution. For example, A solution can be composed of a mixture of N-hydroxysuccinimide carboxymethyl dextrin, sodium hyaluronate, collagen, trehalose hydrate and purified water, and B solution can be composed of a mixture of sodium carbonate, sodium bicarbonate and purified water. First, each syringe body 2 after preparation is inserted into the corresponding card slot 10 until the injection push rod 21 of the syringe body 2 is tightly pressed against the connecting frame 13 and the injection head 20 is in a state of being filled with liquid and overflowing, that is, the excess air in the syringe body 2 is exhausted to ensure that when the connecting frame 13 is pushed, multiple injection heads 20 can discharge liquid together, and then the corresponding injection tube body 22 is clamped by the clamping assembly 12 to ensure that when the connecting frame 13 drives the injection push rod 21 to move, the syringe body 2 will not be stuck. The syringe body 2 slides in the slot 10, thereby completing the installation of the syringe main body 2 and the syringe card slot plate 1. After the multiple syringe main bodies 2 are installed, the multiple plugs 30 of the adapter 3 are sealed and plugged into the corresponding injection heads 20, and then the connection frame 13 is pushed. The connection frame 13 pushes the multiple injection push rods 21 synchronously, and the liquid in the multiple syringe main bodies 2 will enter the mixing tube cavity 32 through the confluence branch 31 to mix. At this time, the A solution and the B solution are mixed evenly in the mixing tube cavity 32, cross-linked and esterified to form a carboxymethyl dextrin-N-hydroxysuccinimide ester fluid dressing, and then the fluid dressing is filtered out of related impurities, microorganisms, etc. through the filter membrane 35 again, and sprayed out in the form of mist through the nozzle 36, attached to the action site, as a temporary physical barrier, to prevent the deposition of fibrin that damages the mesothelium, avoid the formation of bridges and interconnection with the opposite tissue surface, and play an anti-adhesion effect. Afterwards, the gel decomposes at the attachment site, is absorbed into the body, and is finally metabolized and excreted out of the body by the body. It is used for the injured parts of the abdominal wall, abdominal organs, uterus, and uterine appendages under the abdominal incision of patients undergoing abdominal or pelvic surgery to reduce the frequency, range, and degree of postoperative adhesions. At the same time, the air pressure regulating mechanism is set to ensure that the air pressure in the mixing tube cavity 32 is normal, and the drug administration operation can be carried out after the mixing tube cavity 32 is filled with liquid.

[0030] Among them, the clamping assembly 12 includes a threaded hole opened on the side wall of the syringe slot plate 1 and connected to the corresponding slot port 10, and a stud is threaded through the threaded hole; when working, after the syringe body 2 is adjusted to the insertion depth position, the stud is rotated until its inner end is tightly against the outer wall of the injection tube body 22, and the syringe body 2 cannot be pulled out from the slot port 10, thereby completing the clamping limit function.

[0031] The inner end of the stud is provided with a rubber pad for pressing against the injection tube body 22;

[0032] During operation, the rubber pad is mainly used to ensure the degree of clamping, prevent slipping, and prevent the injection tube body 22 from being damaged.

[0033] The gas pressure regulating mechanism includes a gas connecting tube 33 communicating with the mixing tube cavity 32, and a gas pressure regulator 34 is provided at the outer end of the gas connecting tube 33;

[0034] During operation, when the liquid medicine flows into the mixing tube cavity 32 for mixing, the appropriate air pressure in the mixing tube cavity 32 is maintained. During the pushing process of the connecting frame 13, the air pressure regulator 34 can pressurize the inside of the mixing tube cavity 32 through the gas connecting tube 33, thereby increasing the pressure in the mixing tube cavity 32, increasing the pressure at the injection point of the liquid medicine, and improving the atomization effect.

[0035] The connection frame 13 is provided with a frame groove 11 for placing the outer end of the injection push rod 21 . The frame groove 11 can mainly stabilize the pushing action of the injection push rod 21 and improve consistency.

[0036] Wherein, the nozzle 36 is sealed and connected to the mixing cavity 32 in a detachable manner;

[0037] During operation, a threaded or snap-fit ​​connection may be used, mainly to replace or clean the filter membrane 35 in the nozzle 36 . Example 2

[0038] See also Figure 4 The difference between this embodiment and embodiment 1 is that:

[0039] Wherein, a spring assembly for resetting the connecting frame 13 is arranged on the syringe slot plate 1 .

[0040] The spring assembly includes a frame spring slot 14 opened at the bottom center of the syringe card slot plate 1, the frame spring slot 14 has a frame spring 16 with elastic force toward the bottom opening, a frame connecting rod 15 is fixed to the top center of the connecting frame 13, the frame connecting rod 15 is slidably inserted into the frame spring slot 14 and fixedly connected to the frame spring 16;

[0041] During operation, the provided frame spring groove 14 and frame connecting rod 15 can ensure the smoothness of the pushing direction of the connecting frame 13 without tilting, and ensure that the connecting frame 13 can evenly act on the injection push rods 21 of multiple syringe bodies 2, wherein the provided frame spring 16 can automatically reset after the connecting frame 13 is pushed.
