DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waist mat, and more particularly to a medical waist mat used for resting a patient on a post-operative bed and capable of suppressing or reducing the occurrence of back pain. .

[0002]

2. Description of the Related Art In recent years, treatment techniques for ischemic heart disease have been remarkably developed, and in particular, progress in non-surgical treatment using a catheter has been remarkable.
(Hereinafter referred to as "PTCA") is becoming popular, and the number of annual PTCA procedures is nearly 10 times that of three years ago. The time required for PTCA treatment is an average of 1-2 hours, but patients return to their rooms from the operating room with the sheath inserted so that they can respond to emergencies, and rest 6 hours after the sheath is removed the next day. Is released from. Therefore, although it may be shortened in the future, the time required for resting at present is generally about 20 to 24 hours, and the bed adjustment angle is limited so that the sheath does not bend. Up to 30 ° in the supine position and up to 15 ° in the lateral position, but in practice it is almost in a supine position, and more than 90% of patients are aware of low back pain before releasing their rest, and most of them are low back pain. Complain. As a countermeasure for this back pain, putting a compress, putting a back pillow,
Measures such as the combined use of these are taken, and if necessary, analgesics are administered.

[0003] In view of such circumstances, a literature search was conducted, and it was reported in a nursing magazine that a back mat was prepared using Hi-cali Pack to take measures against back pain [Miki Shitara et al. Technology, Vol. 36, No. 15, pp. 27-30 (199
0 year) "A device for relieving low back pain due to long-term bed rest".

[0004]

The application of a compress and the use of a lumbar pillow as described above is an emergency treatment when a patient complains of low back pain, but the effect of alleviating the low back pain cannot be said to be sufficient. Yes, the administration of analgesics is not preferred and the frequency of administration should be minimized. On the other hand, the one described in the above nursing magazine uses a 750 ml high caliper pack as a cushion for the mat, but it can sufficiently alleviate the lower back pain that has occurred and use it immediately after surgery. In order to suppress the occurrence of low back pain itself and to make the degree of low back pain mild, it is important to make further efforts. Accordingly, a basic object of the present invention is to provide a medical waist mat which can solve the above-mentioned problems. An additional object of the present invention is to provide a medical waist mat that reassures the patient and alleviates the mental discomfort of being unable to move because the occurrence and degree of back pain also depends on the patient's mental state. Is to do.

[0005]

Means for Solving the Problems and Means In turn, when a human is divided into a head, a chest, a buttock, and a leg, the direction of the load coincides with the direction of gravity when the human is in a standing position. In the position, the load distribution is 7% for the head, 33% for the chest, 44% for the buttocks, and 16% for the legs. Nearly half of the total load is applied to the lower back, and the skin of the spine, especially the protruding part of the sacrum and hip bone. Suffers strong pressure. If this compression continues for a long time, the blood flow at the site becomes slow, causing low back pain. Therefore, in order to alleviate low back pain, it is necessary to first distribute the load concentrated at one location. In addition, the distortion of the physiological curvature of the spine also causes back pain. That is, the physiological lumbo-sacral angle is about 30 °, but the lumbo-sacral angle in the supine position is about 45 °, and the difference between the angles causes back pain.
In other words, to alleviate the low back pain that occurs when it is required to maintain the supine position for a long time, to reduce the degree of low back pain, and to suppress the occurrence of low back pain itself, It is important that the lumbosacral angle be such that it can sometimes result in body pressure dispersion and that back pain is minimized. Taking these points into consideration, the present inventors have conducted intensive studies, and as a result, the principle of a water bed that can disperse the body pressure applied to the body in the lying position and the principle of an air pillow that can be adjusted in height With attention paid to the fact that the present invention was used to develop a medical waist mat, various basic experiments were conducted, and as a result, the present invention was completed.

Therefore, according to the present invention, there is provided a bag made of a plurality of flexible materials capable of containing and discharging water, and a mat cover having a plurality of bag-shaped portions for accommodating each of these bags. A plurality of air bags disposed below the mat cover, and a manually operated air pump that is individually attached to each of these air bags and is capable of sending and discharging air. The medical waist mat solves the above-mentioned problems and achieves the above object.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In a waist mat according to the present invention,
The above-mentioned water-containing bag is desirably of a size corresponding to a medical 1000 ml infusion pack from the viewpoint of the base area, and the number of the bags is used in order for the bag to stably support the entire waist. It is preferable that the number is six in relation to the above.

In the recumbent position, a strong compression is applied to the waist. Therefore, it is preferable to take into consideration the air permeability, the hygroscopicity and the gradual pressure of the mat cover. In general, Decubitex (trademark) is superior in terms of air permeability and reduced pressure,
Mouton is said to be superior in terms of air permeability and moisture absorption. However, since the waist mat according to the present invention is used after surgery, there is a possibility that it will be contaminated by bleeding, etc.
From the viewpoint of practicality, washing is easy and high durability is required. Therefore, the material is preferably a slightly thick cotton fabric. Incidentally, in the waist mat according to the present invention, the water cover bag is used for the mat cover as described above, and the water temperature is about 30 ° C. or lower, which may cause a feeling of cooling when the waist mat is used. Therefore, for example, a bath towel is laid on the waist mat, so that the material of the mat cover has no influence on the feeling of use of the waist mat.

[0009] In the waist mat according to the present invention, the remaining components, the air bag and the manual air pump, can be similar to the manchette of the sphygmomanometer and the air pump with the pressure adjusting valve, and the structure and the like are also equivalent. Can be It is preferable that the size of the air bag is the same as that of the bag described above, and the number is 3 when the bag containing water is stored in the mat cover (3 pieces x 2 rows). Preferably, the number is The air bag is placed on the bed and the mat cover containing the water storage bag is placed on it, but the air bag may move during use of the waist mat. A long hook-and-loop fastener on one side of the mat cover and across the mat cover
(Magic tape, trademark) is attached, and one side of the air bag is also attached with a hook-and-loop fastener, and the double-sided fastener prevents the air bag from moving and is located at any position within the range of the mat cover. It is preferable that the attachment position of the air bag can be set.

[0010]

Next, the present invention will be described in more detail and specifically with reference to Test Examples and Examples. Preliminary Test Example 1 Voluntary tests were conducted by volunteers to determine how many and how many water storage bags were arranged to support the entire lumbar region and to distribute the pressure applied to the sacrum in particular. That is, a 1000 ml infusion pack is used to set a large base area, and the pack is placed on the bed and at a position corresponding to the lumbar region in four (two juxtaposed x 2 rows) or six (3 juxtaposed x 2). Row), place a bath towel on it and ask them to use it.
Everyone stated that using six was better.

Preliminary Test Example 2 Since the arrangement of the water storage bag was determined based on the results of Preliminary Test Example 1, a preliminary test was conducted by volunteers on the amount of water that affects body pressure dispersion. That is, as in Preliminary Test Example 1, a 1000 ml infusion pack was used, and 800 ml, 900 ml, 1000 ml, or 1100 ml of water was used in each of the six infusion packs. In the case of, the buttocks are too small and the buttocks are stuck on the bed and it is not much different from the state of sleeping on a normal bed, while in the case of 1100 ml, when the waist is moved too much, the flow feeling like a water bed is too strong Not found and good at 900ml and 1000ml. Statistical processing was performed in consideration of body weight, age, and gender when the water capacity was set to 900 ml and 1000 ml, however, no significant difference was observed between the two, and therefore, due to personal preference. 90
It turned out that setting the water capacity to 0-1000ml was no problem.

[0012] Since the amount of placement aspect and water to be contained in each bag of Example Preliminary Test Example 1 and the results bag to be accommodated water from the 2 was found, the prototype medical waist mat. Therefore, this waist mat will be described with reference to the drawings. FIG. 1 schematically shows a use state of a medical waist mat 10 according to the present invention. This medical waist mat 10 basically comprises a water mat 12 and an air bag 14 to be placed under the water mat, and is placed on a bed B to support the waist of the patient H. . When the medical waist mat is actually used, a bath towel is laid on the water mat 12 so as not to give a cold feeling to the patient. Water mat 12 is 6 as shown in Figure 2.
A mat cover 12A having a bag-shaped portion, and a bag body 12B housed in each bag-shaped section. Mat cover 12A is sewn using cotton canvas fabric,
On the other hand, each bag 12B is made using a soft synthetic resin sheet, and is designed to store about 1000 ml of water. One side of the mat cover 12A, that is,
When the medical waist mat 10 shown in FIG. 1 is in use, a plurality of long hook-and-loop fasteners 12a are sewn on the back surface of the surface shown in FIG. The air bag 14 is attached using a hook-and-loop fastener. In this embodiment, there are six water storage bags 12B to be stored in the mat cover 12A, and three water bags 12B are arranged side by side.Thus, three air bags 14 are also arranged side by side. I have. Each of these air bladders 14 has its own independent air pump 14A
The air bag is provided with a hook-and-loop fastener (not shown) which can be engaged with the hook-and-loop fastener 12a attached to the mat cover 12A on one side.
Each of the above air pumps 14A is naturally provided with a pressure regulating valve (not shown).
4A By manually operating the air, the air can be sent into the air bag 14 to increase the internal pressure to inflate the air bag, discharge the air from the air bag, and maintain the air pressure in the air bag at a constant level. Has been made possible.

Since the medical waist mat 10 according to the present embodiment is configured as described above, the mat cover 12A is turned over and the hook-and-loop fastener 12a and the hook-and-loop fastener attached to the air bag 14 are engaged. After three air bladders 14 are mounted, the mat cover 12A is turned over, and the air bladder 14 is placed on the bed B such that the air bladders 14 are positioned at the waist of the patient.
It can be used if 12B is stored in each of the six bag-shaped parts of the mat cover 12A. In this case, the user, that is, the patient who has undergone PTCA, should
For example, by placing a bath towel on the bed and lying on the bed B, the three manual air pumps 14A are operated to send air into the air bag 14 and inflate it. A part of the water mat 12 composed of the body 12B is lifted and the waist is set so that the waist can be supported by the water mat 12 as desired. Thereafter, if the patient intends to lower his / her lower back, the air pump 14A may be operated to evacuate part or all of the air from the central or all air bladders 14, and to the right or left. If it is desired to tilt the waist, air may be discharged from the right or left air bag.
Therefore, the use of this waist mat allows the patient to move his / her waist up and down or tilt it to the right and left without any help from another person such as a nurse. Even when it is required to maintain the lying position for a long time, the above-mentioned lower back movement makes it possible to suppress the occurrence of low back pain and to cope with at least some of the early stages of low back pain generation.

Preliminary Test Example 3 In the medical waist mat according to the present invention, after the PTCA treatment, the patient operates the manual air pumps to appropriately set the internal pressure of the air bladder and to change it at any time. There was a concern that the operation of the air pump caused by this could lead to an increase in blood pressure and adversely affect the post-operative course. Therefore, the medical waist mat obtained by the above example was used by volunteers, the manual air pump was operated as needed, and the blood pressure was measured before and after the operation.
The increase in blood pressure due to the operation of the air pump was 10 mmHg or less, and the effect of grasping the grip of the air pump on the blood pressure had little effect on blood pressure. Therefore, it was considered that there was no problem in the safety of this medical waist mat.

Test Example 1 Patients scheduled to undergo PTCA treatment and patients receiving PTCA again (total
(30, including 22 men, 8 women, ages 40-79)
For the medical waist mats according to the examples, the orientation of the method of use was preliminarily performed, and each of the manual air pumps was actually operated in the supine position, and interviews were conducted on impressions. The results were as follows. Looks good: 69% Looks distracted: 19% Looks interesting: 12%

[0016] For the above patients who received PTCA sequentially,
Immediately after TCA treatment, use of the medical waist mat according to the example was started (each bag holds 1000 ml of water), and when the sheath was removed the next day, the entire water containing bag inside the mat cover was pulled out to stop hemostasis. There was no trouble. After that, without re-introducing the water storage bag into the mat cover, use the air mat only until the rest is released (the last 6 hours during the rest period), and operate each manual air pump freely by operating the air pump freely. Adjustment of pressure, height of air mat, etc. was permitted, and a questionnaire survey was conducted after rest was released.
The questionnaire items and results were as follows. (1) What was the hardest thing during the rest period? Low back pain: 40% Unable to move: 40% Others: 20% (2) How severe was the low back pain? Minor: 60% Insignificant: 10% Neither: 30% (3) Did you take any analgesics? Take: 30% Did not take: 70% (By the way, the medical waist mat according to the present invention The rate of analgesic use when not used is 54% according to past data, and the rate of analgesic use for patients using the medical waist mat according to the present invention is again 0% when PTCA is performed again.
(4) Would you like to use this medical waist mat if you would undergo PTCA again? Would you like to use: 81% Do not want to use: 6% Cannot judge at present: 13% (5) Air The bag was set so that it could be pressurized to about 150 mmHg. Do you have any opinion related to the pressure of the air bag? (A) When the pressure is increased, the inflated part may feel tightly touching the body. The more you raise your waist, the more it feels like a solid ball is hitting it. (b) It is easier to set the pressure to a relatively high
(The majority opinion of those who were relatively easy to have back pain).

Considerations: (1) The use of the medical waist mat according to the present invention has revealed that more than half of the patients have low back pain, and there are individual differences in evaluating the rate of taking analgesics. Difficult but reduced the rate of oral administration when simply evaluated by numerical values. (2) Regarding the most difficult postoperative PTCA
The percentage was related to bed rest, but in view of the same percentage of patients supporting the medical waist mat according to the present invention, this waist mat is judged to be effective in alleviating low back pain. A breakdown of 30% of respondents in the questionnaire who said that the degree of back pain was "neither of the two" was that it was good at first, but that back pain developed with the passage of time. The lack of criteria for evaluating the correlation turned out to be such an answer. Indeed, the bed rest for 20 hours or more is presumed to be more painful than the patient himself imagined, based on the results of the questionnaire. The waist mat according to the present invention is intended to promote blood flow by raising and lowering the waist or tilting the waist up and down by operating the three manual air pumps individually and by the patient himself. Since the mat did not support the entire back, it seemed that with the passage of time from the back to the buttocks, "numbness" occurred and pain gradually appeared.

[0018] In the interview survey during the orientation, there were impressions that "they seem to be distracted" and "it seemed interesting."
A Some people brought back cushions such as waist pillows after remembering the back pain that occurred after the treatment, but looking at the medical waist mat according to the present invention, it may be unnecessary to bring back waist pillows, This is going to make my life a little easier. " Furthermore, in the control of pain and relaxation method, "in pain, the patient tries to endure the pain, the muscles where the pain is felt become tense, so the pain increases. The tension will persist, and the patient will lose calm, so relaxing the body and mind can reduce pain. There is a relaxation method, an autonomous training method, etc. ", and when the patient is aware of such back pain, the patient has no countermeasures, and the nerves are caught by the generated back pain itself. In other words, in the past, there were only dependent measures to call a nurse and have them change their positions a little. You will spend a long time while. That is, in this case, since the back pain produces a back pain, the mental pain is extremely high. However, if the waist mat according to the present invention is used, it is possible to bring about a certain degree of change in the body position by operating a manual air pump, so that it has means capable of coping with low back pain. It is presumed that mental distress has been alleviated as compared with the conventional case. Therefore, the waist mat according to the present invention has an idea based solely on measures against low back pain, but has an unexpected effect on the mental aspect of the patient before and during use.

[0019]

According to the present invention, by supporting the waist with a water mat, the load concentrated on a small portion can be dispersed, and the patient can operate the manual air pump to move the waist up and down or tilt left and right. By doing so, blood flow can be promoted, so that it is possible to suppress blood flow obstruction when maintaining the same posture for a long time and to alleviate the degree of back pain, and to rely on conventional nurses and the like. The change in body position can be performed to a limited extent by the person himself, which alleviates the mental distress of being unable to move for a long time.
