Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a liquid bag pressurizing device. Background Art

[0002] Intraoperative hypothermia is one of the common complications during anesthesia and surgery, especially in patients who need to transfuse a large amount of frozen stored blood, cryogenic fluids, and a large amount of body cavity flushing during long-term surgery, major surgery, surgery on the elderly and children. When the body temperature is <36 degrees Celsius during surgery, it is called intraoperative hypothermia. It is reported that the incidence of intraoperative hypothermia can reach 50% to 70%. Although hypothermia can reduce the body's metabolic rate, reduce oxygen consumption, and increase the tolerance of tissues and organs to ischemia and hypoxia, it still leads to a variety of complications, such as postoperative chills, increased incision infection rate and cardiovascular complications, abnormal coagulation function, delayed anesthesia awakening, etc., which have an adverse effect on the patient's surgical safety. Therefore, the heated blood transfusion and infusion system is often used to quickly pressurize, heat, and remove bubbles during the blood transfusion and infusion process to prevent the patient from having a low body temperature.

[0003] In actual clinical applications, it may be necessary to pressurize the liquid bag by gravity. However, the existing heated blood transfusion and infusion system can only pressurize the liquid bag placed inside it through the pressurization chamber, and does not have the function of gravity pressurization. Therefore, it is inconvenient when gravity pressurization is required. Utility Model Content

[0004] Based on this, in order to solve the above technical problems, a liquid bag pressurizing device is provided.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A liquid bag pressurizing device comprises a pressurizing cabin for pressurizing a liquid bag placed therein, and is characterized in that it also comprises a telescopic rod whose height can be adjusted up and down, the telescopic rod is connected to the pressurizing cabin, and a liquid bag hook is provided on the top of the telescopic rod.

[0007] The liquid bag pressurizing device of the utility model can not only pressurize the liquid bag through the pressurizing cabin, but also pressurize the liquid bag through gravity, so that medical staff can choose the pressurizing method according to actual clinical needs.

[0012] The following will illustrate the implementation methods of the utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent, and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment.

[0013] like Figure 1 As shown, this embodiment provides a fluid bag pressurizing device, which can be applied to a heated blood transfusion and infusion system, and includes a pressurizing cabin 110 and a telescopic rod 120 .

[0014] The pressurized cabin 110 is used to pressurize the liquid bag placed inside it, and includes a cabin body 111, a cabin door 112, and a torsion spring lock hook 113. Figure 2 .

[0015] The cabin 111 has a liquid bag placement chamber 111a with an open front side, and a pressurized bag 111b is arranged in the liquid bag placement chamber 111a. Figure 3 The pressurized bag 111b can be fed with pressurized gas through an external pipeline, thereby pressurizing the liquid bag in the liquid bag placement cavity 111a.

[0016] like Figure 2 As shown, the cabin 111 has a blocking member 111c, which is used to block the liquid bag located in the liquid bag placement cavity 111a at the front side of the liquid bag placement cavity 111a. In this embodiment, the blocking member 111c is an elastic self-recovering member. On the one hand, it can block the liquid bag and prevent the liquid bag from escaping from the liquid bag placement cavity 111a. On the other hand, the cabin door 112 can compress the elastic self-recovering member after closing the liquid bag placement cavity 111a. Due to the effect of the self-recovering force, it is more convenient to open the cabin door 112. For example, the elastic self-recovering member is composed of an L-shaped elastic metal wire, and its lower part is fixed to the lower side of the cabin 111, see Figure 2 .

[0017] The hatch 112 is used to close the liquid bag placement chamber 111a. The hatch 112 is hinged to the left edge of the front side of the cabin body. The lower edge of the hatch 112 has an open structure for the liquid outlet interface of the liquid bag to pass through after the cabin body 111 is closed, so as to avoid the liquid outlet interface being compressed to cause poor liquid discharge. For example, the lower edge of the hatch 112 is in an outwardly arched arc shape, constituting the above-mentioned open structure, see Figure 3 .

[0018] In order to send an indication signal to the blood transfusion and infusion system host when the door 112 is closed, Figure 3 As shown, a travel switch 111d is provided at the front right edge of the cabin body 111, and a pressing block 112a is provided on the inner side of the cabin door 112 for pressing the travel switch 111d after the liquid bag placement cavity 111a is closed.

[0019] The torsion spring lock hook 113 is used to lock the hatch door 112 on the free side (right side) of the hatch door 112. Figure 2 As shown, the lock hook 113 is rotatably fixed to the ear portion 111e formed on the right outer side of the cabin body 111, and the upper side of the lock hook 113 has an arc surface 113a facing the cabin door 112, see Figure 3 Due to the existence of torsion spring 113b, the lock hook 113 is in the locked position without being subjected to external force. During the process of closing the hatch 112, the hatch 112 pushes the lock hook 113 through the curved surface 113a, causing the lock hook 113 to rotate outward. At this time, the torsion spring 113b is compressed, and the hatch 112 is just disengaged from the curved surface 113a after closing. The lock hook 113 returns to the locked position through the self-restoring force of the torsion spring 113b, and just hooks down on the edge of the hatch 112, thereby locking the hatch 112.

[0020] When opening the door 112, the lock hook 113 is rotated outward by the fingers of one hand, and the self-restoring force of the blocking member 111c is cooperated to make the door 112 open automatically, so that the door can be opened with one hand, which is easy to operate.

[0021] Of course, the door 112 and the cabin body 111 may also be locked by their own structures. In this embodiment, the torsion spring lock hook 113 may be omitted.

[0022] like Figure 1 As shown, the telescopic rod 120 can be adjusted in height up and down, is connected to the pressurized cabin 110, and is provided with a liquid bag hook 130 on the top.

[0023] In actual clinical applications, there is also a need to pressurize the liquid bag by gravity. The higher the position of the liquid bag, the greater the pressure. Therefore, when in use, the height of the liquid bag on the liquid bag hook 130 can be adjusted by the telescopic rod 120. At the same time, the height of the liquid bag hook 130 can be lowered by the telescopic rod 120 to facilitate medical staff to hang the liquid bag.

[0024] In this embodiment, if Figure 1 As shown, the telescopic rod 120 includes a first tube 121 and a second tube 122. The first tube 121 is a hollow tube, the lower end of which is fixed to the top of the pressurized cabin 110, and a locking bolt 121a is provided around the upper end. The second tube 122 is inserted into the first tube 121, and a liquid bag hook 130 is provided on the top. When in use, after the second tube 122 is adjusted to a desired height, the height is locked by the locking bolt 121a.

[0025] It can be seen from the above that the liquid bag pressurizing device of this embodiment can not only pressurize the liquid bag through the pressurization cabin, but also pressurize the liquid bag by gravity, which is convenient for medical staff to choose the pressurization method according to actual clinical needs. At the same time, due to the setting of the telescopic rod, it is not only convenient to adjust the height of the liquid bag on the liquid bag hook, but also convenient for medical staff to hang the liquid bag.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
