Description

Technical Field

[0001] The utility model relates to the technical field of the structural design of a saline supply and storage device used in cardiac surgery, in particular to a saline constant temperature storage device during surgery. Background Art

[0002] During surgical operations, when using polypropylene suture (PROLENE) on the operating table, in order to make the suture easy to lift and tie knots, it is often necessary to pour water on the hands of the surgeon and the assistant who hold the suture.

[0003] During cardiac surgery, almost every operation requires frequent pouring of water.

[0004] With the rapid progress of surgical techniques and the increase in beating-heart surgeries, during beating-heart surgeries, warm saline must be used on the sterile table to avoid cold water stimulating the heart, which may cause the risk of cardiac arrest.

[0005] Also, before closing the chest or abdomen, warm saline is routinely used to irrigate the chest or abdomen. The first purpose is to wash away the tissue residues or impurities left over from the operation; the second is to play an anti-inflammatory and hemostatic role; the third is to prevent the patient from hypothermia and play a role in keeping warm. Therefore, the demand for warm saline on the operating table cannot be ignored.

[0006] Currently, in the operating room, sterile normal saline is heated in a special liquid warming box for the operating room. When needed, the circulating nurse takes it out, opens the outer packaging, and hands it to the sterile table. The instrument nurse cuts a small opening with scissors and inserts a water injection ball into the opening to aspirate and use it when needed.

[0007] There are the following problems:

[0008] First, since the size of the opening cut by the scissors does not match the size of the water injection ball, it is easy for the sterile saline to spill onto the sterile drape when aspirating the saline, causing the risk of wetting and contaminating the sterile drape.

[0009] Second, due to the poor heat preservation effect of ordinary saline bags, when the operation time is long, it is often found that the warm saline in the saline bag on the table has cooled down before it is used up, and it is necessary to repeatedly heat the warm saline.

[0010] Third, especially during OFFPUMP bypass surgery, the requirements for warm saline are more stringent. Coupled with the long operation time, the replacement of warm saline on the table is more frequent, increasing the workload of nurses and also causing waste of sterile saline.

[0011] Sometimes, some nurses will also wrap the saline bag with the sterile towel on the table to increase the heat preservation duration. However, the sterile towel is too large and inconvenient to wrap. Each time of aspiration requires opening the wrapped sterile towel first, and it is easy to leak water and wet the sterile towel during aspiration.

[0012] It can be seen that in the prior art, there is no device with a reasonable structure for the supply equipment of warm saline in cardiac surgery, which causes serious troubles for the supply of a large amount of warm saline used in the surgery. Such a small defect problem greatly affects the surgical effect. Summary of the Invention

[0060] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0064] As Figures 1-5 As shown, the saline constant temperature memory in this operation includes: a storage bag 1 mainly for storing warm saline used during the operation and a suction pipe 2 for facilitating the discharge of the saline in the storage bag 1. The suction pipe 2 is threadedly connected to the opening of the storage bag 1. The threaded connection method can facilitate the removal of the suction pipe 2, so as to meet the requirements of multiple uses of the storage bag 1 and the injection of warm saline. In order to prevent the liquid in the suction pipe 2 from flowing back into the storage bag 1 and to facilitate the insertion of use utensils such as a water injection ball into the suction pipe 2 to suck the saline, a one-way valve 3 is provided on the side of the suction pipe 2 close to the storage bag 1 to ensure that the saline in the storage bag 1 flows into the suction pipe 2 unidirectionally. In order to seal the suction pipe 2 and only allow the saline in the suction pipe 2 to be discharged when a use utensil such as a water injection ball is inserted, a diaphragm seal 4 is provided at the end of the suction pipe 2 away from the storage bag.

[0065] In order to improve the heat preservation effect of the storage bag 1 and meet the requirement of continuously supplying appropriate-temperature saline during a long surgical procedure. A heat preservation bag is sleeved outside the storage bag 1. The separate sleeving method facilitates the cleaning and replacement of the heat preservation bag. Especially during the surgical procedure, the heat preservation bag is prone to being contaminated. The separate replacement method can conveniently meet the requirement of the repeated use of the storage bag 1.

[0066] In order to facilitate the connection between the storage bag 1 and the suction pipe 2, especially to conveniently remove the suction pipe 2 to meet the requirement of injecting saline into the storage bag 1 for use during the surgery. A connecting pipe 5 is fixedly connected to the opening of the storage bag 1, and the outer wall of the connecting pipe 5 is threadedly connected to the suction pipe 2. By integrally molding or fixedly bonding the connecting pipe 5 in a sealed manner, a rigid connecting structure can be extended from the flexible material structure of the storage bag 1, which can facilitate the detachable connection with the suction pipe 2.

[0067] In order to achieve the one-way conduction function of the suction pipe 2, ensure that the saline can smoothly flow from the storage bag into the suction pipe 2, and the contaminated saline in the suction pipe 2 will not flow back into the storage bag 1, reducing the possibility of the saline in the storage bag 1 being contaminated and improving the cleaning effect of the saline. The one-way valve 3 includes: a support frame 31 for support and guidance; a sliding plug 32 for achieving one-way sealing. The support frame 31 is fixedly connected to the inner wall of the suction pipe 1, and the sliding plug 32 is sleeved on the support frame 31 to provide support for the sliding direction of the sliding plug 32 and ensure the support effect of the sliding plug 32.

[0068] In order to meet the sealing effect of the sliding plug 32 on the suction pipe 2, especially when the saline flows back from the suction pipe 2 into the storage bag 1, the suction pipe 2 can be sealed to prevent the contaminated saline in the suction pipe 2 from flowing into the storage bag 1. A circulation hole 21 is opened in the middle of one end of the suction pipe 2 close to the storage bag 1, and the overall maximum outer diameter of all the circulation holes 21 is smaller than the outer diameter of the sliding plug 32; that is to say, when the sliding plug 32 slides towards the circulation hole 21, it can completely cover all the circulation holes 21 to meet the plugging of the circulation hole 21, so that the saline will not flow into the storage bag 1.

[0069] Of course, in order for the saline to flow smoothly from the storage bag 1 into the suction pipe 2. The outer diameter of the sliding plug 32 is smaller than the inner diameter of the suction pipe 2; under the impact of the saline in the storage bag 1, the sliding plug 32 slides away from the circulation hole 21, and the saline flows along the circulation hole 21 into the interior of the suction pipe 2 to achieve the one-way conduction function of the one-way valve.

[0070] In order to ensure that the saline can smoothly flow into the interior of the suction pipe 2 after flowing past the edge of the sliding plug 32, a circulation slot 33 is opened at the position where the support frame 31 is close to the inner wall of the suction pipe 2. The support frame 31 supports and limits the sliding distance of the sliding plug 32, and the saline can flow along the edge of the sliding plug 32 and into the interior of the suction pipe 2 through the circulation slot 33.

[0071] To ensure the flow effect of the flow holes 21 and to support and fix the support frame 31 at one end of the flow holes 21. A plurality of the flow holes 21 are provided, and the plurality of flow holes 21 enclose a circle. A connection seat 22 is provided at the center of the flow holes 21, and one end of the support frame 31 is fixedly connected to the connection seat 22. This not only increases the entire flow area of the flow holes 21, but also further improves the fixed connection strength of the support frame 31 through the fixing effect of the connection seat 22.

[0072] To further improve the effect of the support frame 31 in circulating brine and to satisfy the support and sliding effect on the sliding plug 32. The support frame 31 includes: a notch frame 311 that is connected to the suction pipe 2 and allows brine to flow through; a connecting rod 312 that supports the sliding plug 32 and provides a sliding channel for the sliding plug 32. The connecting rod 312 is fixedly connected to the center of the notch frame 311, and the lower end of the connecting rod 312 is fixedly connected to the connection seat 22.

[0073] The sliding plug 32 is sleeved on the outer wall of the connecting rod 312; the sliding plug 32 slides along the connecting rod 312.

[0074] To avoid the blocking effect of the sliding plug 32 and ensure the flow effect of the flow notch 33. The flow notch 33 is provided at the edge of the notch frame 311. When the sliding plug 32 slides to one side close to the notch frame 311, at the edge position of the notch frame 311, the flow notch 33 can smoothly allow brine to flow through, satisfying the effect of one-way conduction.

[0075] To facilitate the fixing effect on the notch frame 311, a fixing protrusion 23 is convexly provided on the inner wall of the suction pipe 2, and the fixing protrusion 23 limits and fixes the edge of the notch frame 311;

[0076] To improve the flow effect of the notch frame 311 and the effect of the one-way valve in one-way circulating brine. The notch frame 311 includes: a connecting rod 313 that connects to the inner wall of the suction pipe 2 and a central seat 314 that fixedly supports the connecting rod 312. A plurality of connecting rods 313 are connected to the edge of the central seat 314, and the circumference formed by the ends of the plurality of connecting rods 313 away from the central seat 314 is the same as the inner diameter of the suction pipe 2; that is to say, the ends of the connecting rods 313 away from the central seat 314 are attached to the inner wall of the suction pipe 2 and are limited and fixed by the fixing protrusion 23.

[0077] The flow notch 33 is formed between adjacent connecting rods 313. Preferably, three or four connecting rods 313 are provided, which can leave a flow notch 33 with sufficient size between the connecting rods 313.

[0078] To facilitate the connection between the suction pipe 2 and the connecting pipe 5 and ensure that the connecting pipe does not affect the one-way conduction effect of the one-way valve 3, a connecting cylinder 24 extends from the outer wall of the suction pipe 2 at the edge of the through-hole 21, and internal threads are provided on the inner wall of the connecting cylinder 24 to connect the connecting pipe 5.

[0079] Preferably, the inner diameter of the connecting pipe 5 is the same as the outer diameter of the circle formed by the plurality of through-holes 21.

[0080] To ensure smooth conduction when the water injection ball is inserted into the suction pipe 2 and prevent the saline solution inside the suction pipe 2 from flowing out under a small pressure (the internal pressure of the suction pipe 2 is very small). A diaphragm seal 4 is fixedly connected to the upper end of the suction pipe 2; of course, the diaphragm seal 4 is made of an elastic material and can deform within a certain space to accommodate the insertion of the water chasing ball.

[0081] When not in use, for example, during non-surgical procedures, the diaphragm seal 4 can be covered to prevent contamination. A sealing plug 6 is also provided at the end of the diaphragm seal 4 away from the suction pipe 2.

[0082] To facilitate the insertion of the front end of the water injection ball into the suction pipe 2 and achieve the suction effect on the saline solution inside the suction pipe 2. The diaphragm seal 4 is of a circular structure, and a Y-shaped slit or a cross-shaped slit is provided in the center of the diaphragm seal 4; the total length of the cross-shaped slit, or twice the length of each slit of the Y-shaped slit, is the same as the diameter of the front-end straw of the water injection ball, which can ensure the sealing effect of the diaphragm seal 4 while allowing the insertion of the water injection ball.

[0083] To facilitate the fixation of the diaphragm seal 4 and its installation. A diaphragm connection head 25 protrudes from the end of the suction pipe 2 at the edge of the diaphragm seal 4, and a diaphragm pressing member 26 is fixedly connected inside the diaphragm connection head 25 to press the diaphragm seal 4.

[0084] To improve the sealing effect of the diaphragm seal 4 and reduce the defect of saline solution leaking along the diaphragm seal 4. The diaphragm seal is a hemispherical structure with a downward bulge in the middle. When the saline solution inside the suction pipe 2 impacts the diaphragm seal 4, the slit of the diaphragm seal 4 is tightened more, improving the sealing effect of the diaphragm seal 4.

[0085] In order to improve the sealing effect and provide a supporting function for the diaphragm seal 4 of the hemispherical structure, the sealing plug 6 includes a sealing cylinder 61 for connection and a support rod 62 for supporting the diaphragm seal 4. One end of the sealing cylinder 61 is sealed with a sealing plate 63, and the center of the sealing plate 63 is fixedly connected to the support rod 62, and the support rod 62 extends into the upper side of the diaphragm seal 4; to avoid the defect that the support force of the diaphragm seal 4 made of elastic material is insufficient, resulting in the leakage of brine from the diaphragm seal 4. Through the auxiliary support function of the support rod 62, it is ensured that the diaphragm seal 4 will not be extruded and deformed by the brine in the suction pipe 2.

[0086] Preferably, the support rod 62 is a plate-like structure with a cross-section in the shape of a cross, which can meet the support function, reduce the size, and conveniently extend along the diaphragm pressing member 26.

[0087] In order to facilitate the connection between the sealing cylinder 61 and the suction pipe 2, the end of the sealing cylinder 61 away from the sealing plate 63 is threadedly connected to the outer wall of the diaphragm connector 25. Through the diaphragm connector 25 fixedly connected to the end of the suction pipe 2, the connection between the sealing cylinder 61 and the suction pipe 2 is realized.

[0088] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
