Description

TECHNICAL FIELD

[0001] The present disclosure relates to medical aids. More particularly, it relates to a visit bag for patients undergoing peritoneal equilibration test. BACKGROUND

[0002] Patients with severe chronic kidney disease can be treated with peritoneal dialysis (PD). A common complication of peritoneal dialysis treatment is peritonitis, which is a common cause of temporary or permanent termination of peritoneal dialysis for patients. Delayed diagnosis of peritonitis can also lead to death. In addition, there are many complications that can occur during peritoneal dialysis.

[0003] Peritoneal dialysis is to use the peritoneum of the human body itself as a semi-permeable membrane, utilize the solute concentration difference on both sides of the peritoneum, continuously and slowly remove metabolic products and excess water in the body, so as to maintain the stability of the body internal environment, and achieve the purpose of blood purification, which is one of the main methods of kidney replacement therapy.

[0004] Patients need to complete the dialysis process themselves during home treatment. In addition, patients need to go to the hospital for outpatient review every 1 to 3 months, including regularly performing peritoneal equilibration test (PET; for example, once every 3 months). Generally, the attending physician will adjust the dialysis prescription, oral medicine prescription, etc. according to the results of the peritoneal equilibration test. The significance of peritoneal equilibration test includes but is not limited to: evaluating peritoneal transport function (e.g., determining peritoneal transport type, developing individualized dialysis plan); monitoring dialysis effect (e.g., evaluating solute clearance rate, monitoring water ultrafiltration); predicting complication risk (e.g., predicting peritonitis risk, assessing nutritional status); guiding treatment adjustment (e.g., timely adjusting treatment plan, guiding drug dosage adjustment). In summary, peritoneal equilibration test provides an important evaluation tool for peritoneal dialysis patients, which helps to achieve individualized dialysis treatment, improve dialysis effect, reduce the occurrence of complications, and improve the quality of life of patients.

[0005] Generally, a patient to be subjected to a peritoneal equilibration test needs to retain peritoneal dialysate in the abdomen (for up to 8 to 12 hours before the day of the test) the day before coming to the hospital. After the patient comes to the hospital on the day of the test (e.g., in the morning), the patient is guided by medical staff to connect a first end of a "Y" shaped catheter of a "double double bag" (i.e., a first bag B1 filled with dialysate, a second bag B2 for drainage, and a "Y" shaped catheter connected to the first bag B1 and the second bag B2) to one end of a peritoneal dialysis extension tube, connect the other end of the peritoneal dialysis extension tube to a titanium joint of a peritoneal dialysis tube extending from the patient's abdomen, connect a second end of the "Y" shaped catheter to the first bag B1 filled with fresh peritoneal dialysate (i.e., new fluid, typically 1000 to 2000 ml), and connect a third end of the "Y" shaped catheter to the second bag B2 (i.e., a drainage bag) for receiving old dialysate (i.e., old fluid) in the patient's abdominal cavity. With the connection, the old fluid is drained (i.e., the old fluid retained in the abdomen is drained into the second bag B2), and the new fluid is infused (i.e., the new fluid in the first bag B1 is infused into the patient's abdominal cavity, and the first bag B1 is emptied). Then, the patient stays in the hospital for more than 4 hours with the first bag B1 and the second bag B2 connected to complete blood drawing and sampling, etc. Typically, a nurse draws a blood sample once and takes three peritoneal dialysate samples at predetermined time intervals during the stay. After the peritoneal equilibration test is completed, the connection between the "Y" shaped catheter and the peritoneal dialysis extension tube is disconnected, and the used first bag, second bag, and "Y" shaped catheter are discarded.

[0006] A patient coming to the hospital for a peritoneal equilibration test carries many items, and it is easy to miss one or more items. Typically, the patient coming to the hospital carries multiple bags to accommodate the required items. During the outpatient review including the peritoneal equilibration test, the patient may carry the "double double bag" in one hand, and complete the steps of taking medicine, paying, receiving blood drawing, and collecting test results, etc., and the patient's movement is limited. In addition, the peritoneal dialysis tube may be accidentally pulled, causing the patient to be uncomfortable, and even causing peritonitis. Invention content

[0017] Exemplary embodiments of this disclosure will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual embodiments are described in the specification. However, it should be understood that many embodiment-specific decisions can be made in the development of any such actual embodiment to achieve the developer’s specific objectives, and these decisions may vary as the embodiments differ.

[0018] It should also be noted that, in order to avoid obscuring the contents of this disclosure with unnecessary details, only the device structure closely related to the solution according to this disclosure is shown in the accompanying drawings, while other details that are not closely related to this disclosure are omitted.

[0019] It should be understood that this disclosure is not limited to the described embodiments by virtue of the following description with reference to the accompanying drawings. Throughout this document, embodiments may be combined with each other, features may be substituted or borrowed between different embodiments, and one or more features may be omitted in one embodiment. The same reference numerals in different drawings may denote the same features.

[0020] One aspect of this disclosure relates to a patient bag for undergoing a peritoneal balancing test. This patient bag is particularly suitable for use as a "backpack" by patients with kidney disease during peritoneal balancing tests in a medical facility (e.g., a hospital). That is, the patient bag is a backpack suitable for use by patients undergoing peritoneal balancing tests during their medical visit, serving as a portable container and an auxiliary medical aid. Reference is made below. Figures 1 to 5 An exemplary description is provided.

[0021] Figure 1 An exemplary medical package 10 for a patient undergoing a peritoneal balancing test is shown according to one embodiment of the present disclosure. Figure 2 This is a schematic diagram showing the perspective structure of the medical bag 10, in which, for clarity, some details such as the entrance on the back of the medical bag 10 are not shown. Figure 3 A schematic view of the back of a medical bag 10 according to one embodiment of this disclosure is shown, wherein, for clarity, some details such as the shoulder straps are not shown. Figure 1 As shown, the medical bag 10 includes: a backpack body 110 extending along a first direction Z (i.e., the height direction of the medical bag); and two shoulder straps connected to the backpack body 110 to enable the medical bag 10 to be used as a backpack: a first shoulder strap 130-1 and a second shoulder strap 130-2 (also referred to as "shoulder strap 130" when no distinction is made). The backpack body 110 includes a front compartment 111 and a rear compartment 113 arranged along a second direction X perpendicular to the first direction Z. The rear compartment 113 includes a top compartment bottom 113U-b (see reference) that divides the internal space of the rear compartment along the first direction Z into a top compartment 113U and a bottom compartment 113L.Figure 2 ) is set so that the height of the bottom compartment in the first direction Z is in the range of 13 cm to 19 cm to accommodate the dialysis fluid bag and the drainage bag. The bottom compartment 113L has an entrance 113L-e provided on the back of the clinic bag 10 to place the dialysis fluid bag and the drainage bag into the bottom compartment 113L from the entrance 113L-e (see FIG. 2B). Figure 3 That is, the size of the bottom compartment is set according to the size of the “double double bag” to be suitable for placing the “double double bag”.

[0022] The clinic bag 10 is provided with the bottom compartment 113L intended to place the dialysis fluid bag and the drainage bag (“double double bag”), and the entrance 113L-e of the bottom compartment 113L is provided on the back of the clinic bag 10. In this way, during the peritoneal equilibrium test, after the introduction of fresh dialysis fluid, the patient can put the drainage bag, part of the catheter, and the empty dialysis fluid bag (for example, double double bag) into the bottom compartment, and put the clinic bag in front of the chest (referred to as “front use mode”), complete the steps of taking medicine, paying, receiving blood sampling, and receiving test results. During this period, the items carried by the patient can be placed in the respective compartments or sub-bags of the clinic bag, and the patient does not need to carry the bag with his hands, so as to free his hands, and the patient can conveniently take the items needed from the front clinic bag, and the patient’s hands can be free to handle various matters. At the same time, in this front use mode, the bottom compartment of the clinic bag containing the dialysis fluid bag and the drainage bag is close to the peritoneal dialysis catheter outlet of the patient’s abdomen, and compared with the case of carrying the dialysis fluid bag, the length of the exposed catheter between the clinic bag and the peritoneal dialysis catheter outlet can be kept short, the environment around the catheter is within the visual range of the patient, and most of the items are stored in the top compartment or the front compartment, and when taking these items, the possibility of accidentally pulling the catheter or violently disturbing the catheter is low, so it is not easy to occur that the catheter is accidentally pulled. Therefore, the clinic bag of the present disclosure brings convenience and safety to the patient who comes to the hospital for peritoneal equilibrium test.

[0023] Considering that the patient is not suitable to carry too heavy items, and when the backpack is too large, it blocks the line of sight during use, is easy to collide, and may touch the peritoneal dialysis catheter outlet, the preferred size of the clinic bag of the present disclosure is not more than 48 cm*31 cm*25 cm (height*length*width, i.e., Z direction size*Y direction size*X direction size, wherein the X direction, the Y direction, and the Z direction are perpendicular to each other). Preferably, the height of the backpack body (the height from the bottom of the bottom compartment to the sewing surface of the handle) is not more than 45 cm. For example, the height of the backpack body is in the range of 38 cm to 41 cm, and the height of the bottom compartment is in the range of 13 cm to 17 cm.

[0024] In view of the fact that the patient has a peritoneal dialysis catheter exit in the abdomen, the bottom of the bag body of the visit pack is preferably distanced from the peritoneal dialysis catheter exit when the visit pack is in the front use mode (i.e. the visit pack is slung in front of the chest). Although it is possible to shorten the shoulder straps using the common "O" shaped length adjustment buckles and / or "H" shaped length adjustment buckles on the shoulder straps (optionally, such "O" shaped length adjustment buckles and / or "H" shaped length adjustment buckles can be provided for the visit pack 10). However, this can be annoying (e.g. after the completion of the visit, the opposite process of lengthening the shoulder straps using the "O" shaped length adjustment buckles needs to be performed to carry the visit pack in the comfortable back use mode of carrying the visit pack on the way home, in which the comfortable back use mode requires longer shoulder straps than the front use mode) and inconvenient. In one embodiment, the visit pack further comprises buckles for quick shortening of the shoulder straps. Figure 4 An exemplary view of a buckle 40 for use in the present embodiment is shown. The buckle 40 comprises a male head 401 and a female head 403. Figure 5 An exemplary visit pack 50 for a patient undergoing a peritoneal equilibration test is shown according to one embodiment of the present disclosure, in which some details such as the entry on the back of the visit pack 50 are not shown for clarity. For each of the two shoulder straps of the visit pack 50 (take the shoulder strap 130-2 as an example): the shoulder strap has a main shoulder strap 130-2m for slinging over the shoulder, an additional connecting strap 501 and a buckle for shortening the length of the main shoulder strap; the buckle has a male head 401 and a female head 403; one of the male head and the female head (exemplarily shown as the female head 403) is directly fixed at a first predetermined position of the main shoulder strap 130-2m; the other of the male head and the female head (exemplarily shown as the male head 401) is directly fixed at a second predetermined position of the additional connecting strap 501. Figure 5 The first predetermined position and the second predetermined position are arranged such that the main shoulder strap 130-2m and the additional connecting strap 501 are in a substantially parallel arrangement when the visit pack 50 is in the front use mode. Figure 5Exemplarily shown is that the male head (401) is connected to the first end of the additional connecting strap (501); the second end of the additional connecting strap (501) is connected to the main shoulder strap at the second predetermined position of the main shoulder strap so that the shoulder strap becomes shorter after the male head and the female head are buckled. The other shoulder strap (130-1) is also configured with the same structure as the shoulder strap (130-2). Thus, when the patient places the medical treatment bag in the front, the shoulder strap can be quickly shortened (i.e., the actual use length of the shoulder strap becomes shorter) by using the buckle structure to avoid the bottom of the bottom compartment accidentally touching the peritoneal dialysis tube outlet. Optionally, only one shoulder strap (e.g., the shoulder strap on the side close to the interface) can be shortened. The additional connecting strap can be configured as an additional connecting strap with adjustable length. For example, a "mesh" - shaped length adjustment buckle and / or a "day" - shaped length adjustment buckle can also be configured for the additional connecting strap to make the length of the additional connecting strap adjustable. Thus, the medical treatment bag is suitable for patients with different physiques. After the patient pre - adjusts (e.g., at home) the length of the additional connecting strap to a length suitable for himself / herself, in the front - placed use mode (e.g., when visiting the hospital), the shoulder strap can be quickly shortened to a predetermined length by buckling the buckle, and before enabling the rear - placed use mode (e.g., before going home from the hospital), the shoulder strap can be quickly restored to a longer state by loosening the buckle. It can be understood that the medical treatment bag of the present disclosure can be configured such that each main shoulder strap includes a length adjustment buckle, each additional connecting strap includes a length adjustment buckle, and a buckle for quickly adjusting the length of the shoulder strap is configured between the main shoulder of each shoulder strap and its corresponding additional connecting strap.

[0025] In one embodiment, a lid can be configured for the bottom compartment to prevent items in the compartment from falling out. As Figure 3 shown, a bottom compartment lid (113L - c) covering the inlet (113L - e) is arranged on the back of the medical treatment bag (10). The first side (i.e., the upper edge) of the bottom compartment lid (113L - c) is sewn to the back of the medical treatment bag. The bottom compartment lid has a plurality of buttonholes. A plurality of buttons (e.g., button 301) corresponding to the plurality of buttonholes are arranged on the back of the medical treatment bag (10) to connect the bottom compartment lid (i.e., the lower edge of the bottom compartment lid) to the back of the medical treatment bag through the plurality of buttonholes and the plurality of buttons. This structure enables the catheter to pass through the gap of the inlet even when the buttons are buckled. And no zipper is used to prevent metal burrs from accidentally scratching the dialysis solution bag or the drainage bag. It can be understood that although not preferred, it is also possible to configure a zipper for the inlet to close the inlet.

[0026] In one embodiment, the bottom compartment lid is an isosceles trapezoid.

[0027] In one embodiment, the backpack body can further include two side pockets provided on both sides of the backpack body (see Figure 1Alternatively, an opening of the open-bottom compartment is provided on one side of the visit bag. That is, the open-bottom compartment can further comprise an opening on the side of the visit bag, which is in communication with the inlet to lead out the catheter for peritoneal equilibration test. Further, a buckle is provided on the upper and lower sides of the opening and close to the inlet, so as to achieve that after the "double-double bag" is put into the open-bottom compartment and the catheter is led out from the side of the visit bag, the male head and the female head of the buckle are buckled, so that the inlet and / or the opening of the open-bottom compartment are not excessively sagged.

[0028] In one embodiment, the backpack body further comprises a transparent bag (see Figure 3 transparent bag 170 in FIG. 1) provided on the back of the visit bag. The transparent bag can be used to clip the contact information of family members, the description of the patient's condition, the check list of carrying articles, etc. In order to facilitate the medical staff to contact the patient's family members and quickly understand the patient's condition in the case of emergency; and, to facilitate the patient to take the articles according to the check list before leaving home to go to the hospital for treatment.

[0029] In one embodiment, the volume of the top compartment is greater than the volume of the bottom compartment. The large top compartment can be used to accommodate other articles in addition to the dialysis liquid bag, such as food, mobile phone, medicine, other dialysis articles, etc. In one example, a (first) elastic band with both ends fixed is provided in the bottom compartment to bind the dialysis liquid bag and the drainage bag, or a second elastic band to fix the catheter is further provided.

[0030] In one embodiment, the top compartment comprises a main volume space and a plurality of discrete sub-bags provided on the inner wall of the top compartment, so as to classify and place the articles for easy searching.

[0031] In one embodiment, the visit bag further comprises a handle (see Figure 1 handle 190 in FIG. 1) provided on the top of the backpack body.

[0032] In one embodiment, the thickness of the bottom of the top compartment is greater than the thickness of the bottom of the bottom compartment (for example, the bottom of the top compartment can comprise a sandwich layer, in which a buffer pad with a thickness of more than 2 cm, a hard partition, etc. are placed). This can prevent the articles in the top compartment from accidentally damaging or damaging (including puncturing) the articles (such as the dialysis liquid bag and the drainage bag) in the bottom compartment. In one example, a removable strip-shaped pad (length direction along the Y direction) with a thickness of 2 cm to 5 cm is provided above the inlet on the back of the visit bag. In the front use mode, the strip-shaped pad can be removed in the rear mode, to weaken the movement or stress of the catheter extending from the bottom compartment due to the movement of the back of the visit bag relative to the patient's abdomen.

[0033] Compared with the common clinic bag, the scheme of the present disclosure has the beneficial effects including but not limited to: the clinic bag of the present disclosure is specially designed for peritoneal balance test, and the structure is scientific and reasonable; a storage space is provided for the items that can be used in the clinic process, and the use is safe and convenient; the clinic bag of the present disclosure avoids carrying multiple bags during the clinic, and also avoids holding the bag with one hand or both hands; during the journey, the clinic bag can be used as an ordinary clinic bag, and the clinic bag is carried on the back; during the clinic process in the hospital, the shoulder strap can be quickly shortened through the buckle on the shoulder strap, and the clinic bag is carried in front of the body (in "front use mode"), so as to facilitate taking the required items; during the peritoneal balance test, the peritoneal dialysis liquid bag and the drainage bag connected with the peritoneal dialysis external pipe can be placed in the bottom compartment, and the clinic bag is used in "front use mode", which can not only reduce the pulling and avoid the radial movement of the peritoneal dialysis pipe caused by external force, thereby reducing the possibility of peritoneal dialysis related peritonitis, but also facilitate the patient to complete the payment, medicine taking, test sheet taking, and taking items from the top compartment or front compartment of the clinic bag, etc. with both hands. At the same time, the actions and operations of the patient have little effect on the catheter connected to the patient's abdomen, and the possibility of accidental pulling of the catheter is minimized.

[0034] As described above, according to the present disclosure, the design principle of the clinic bag for the patient receiving the peritoneal balance test has been disclosed. It should be noted that the effects of the scheme of the present disclosure are not necessarily limited to the above-mentioned effects, and in addition to or instead of the effects described in the preceding paragraph, any of the effects shown in the present specification or other effects that can be understood from the present specification can be achieved.

[0035] It should be emphasized that the term "comprises / comprising" as used herein refers to the presence of the features, elements, steps or components, but does not exclude the presence or addition of one or more other features, elements, steps or components.

[0036] Although the present application has been disclosed by the description of the specific embodiments of the present application above, it should be understood that those skilled in the art can design various modifications (including the combination or replacement of features between embodiments, if feasible), improvements or equivalents of the present application within the spirit and scope of the appended claims. These modifications, improvements or equivalents should also be considered to be included in the protection scope of the present disclosure.
